2012 38th Annual Conference of the Eastern Community College Social Science Association (ECCSSA) Center for Innovative Technology 2214 Rock Hill Road Herndon VA ldquoThe Great Renewal Rebuilding Our NationmdashVisions and Challengesrdquo March 30 2012 Presenters Dipak K (Dee) Roy and Ian Taylor

1Theory both ldquorepresentative agentrdquo (RA) ndashbased and DSGE models ignore adaptive interactions of a variety of actors in networks that lead to crisis Big weakness Treats colds not serious illnesses (Stiglitz) 2 Policy complex systems science may provide essential insight about economic outcomes--better guidance and tools for regulation (eg mapping of financial networks)

Why is Economics not an Evolutionary Science Thorstein Veblen The Quarterly Journal of Economics vol 12 1898 On the individual in economic theory ldquoHe is an isolated definitive human datum in stable equilibrium except for the buffets of the impinging forces that displace him in one direction or anotherrdquo On the reality ldquoThe economic life history of the individual

is a cumulative process of adaptation of means to ends that cumulatively change as the process goes onhelliprdquo

Classical economics is a ldquotaxonomicrdquo discipline not an evolutionary one

Assumption of ldquoconstrained optimization by representative agentsrdquo ignores the adaptive and historical nature of economic relationships processes and their consequences (Foster 2004)

Standard macro models do not consider the

networked aspects of lending and global banking

(Gallegati Stiglitz 2011)

ldquoEconomic theory based on the RA model has in short nothing to say about financial crises bankruptcies dominorsquos (sic) effects systemic risk and any pathology in generalrdquo Heterogeneous Interacting Agent Models for Understanding Monetary Economies Joseph E Stiglitz and Mauro Gallegati Eastern Economic Journal 2011 37 (6ndash12)

ldquo The era of globalization is the era of connectedness This reality represents an increasingly troubling challenge to traditional theories and models of social systems which assume the independence of individuals from their broader social milieurdquo httpwwwiqharvardedublognetgov

ldquohellipinterdependencies across different systems and markets are potentially more important for financial stability than interdependencies within the system This is the case because these types of links have the potential to dramatically change the behaviour of market participantsrdquo --European Central Bank (ECB) ldquoRecent advances in modelling systemic risk using network analysisrdquo January 2010 (p 25)

ldquoWithin a certain range connections serve as a shock-absorber The system acts as a mutual insurance device with disturbances dispersed and dissipated Connectivity engenders robustness Risk-sharing ndash diversification ndash prevails But beyond a certain range the system can flip the wrong side of the knife-edge Interconnections serve as shock-amplifiers not dampeners as losses cascaderdquo

1 Financial networks now spread contagion much like

a disease epidemic (Stiglitz 2010)

2 Public health epidemics are stopped through quarantine

3 In finance similar policy needed capital controls (circuit breakers)

ldquoWith fluctuations in the supply of credit being at the center of many economic fluctuations a theory that has little to say about credit and its determinants is obviously of limited userdquo --standard models assume shocks are exogenous Stiglitz indicates that they are now often man-made endogenous ldquothe sub-prime mortgage crisis was man-maderdquo (p 596 Rethinking Macroeconomics)

ldquohellipStandard Models focusing on money not credit where banks and security markets were not well analyzed provided little guidance on how government could restore the flow of credit Thatmdashnot interest ratesmdashwas the central issuerdquo (p609) RETHINKING MACROECONOMICS WHAT FAILED AND HOW TO REPAIR IT Joseph Stiglitz Journal of the European Economic Association August 2011

ldquoMacro models agree that optimal monetary policy is to keep interest rates low to avoid sectoral misallocationrdquo

Stiglitz argues otherwise puts him ironically on the same page as the Austrian economists icons of the Tea Partyists and Rep Ron Paul Thatrsquos a revolution

ldquoWhile the economic system sometimes amplifies shocks standard theory argues that economic systems do just the opposite through several mechanismsrdquo ldquoUnderstanding amplificationmdashhow small disturbances can give rise to large effectsmdashshould be one of the key objectives of macroeconomic researchrdquo ldquohellipeconomic systems (viewed as complex adaptive processes) may exhibit major phase transitionsrdquo This is where the revolution in macroeconomics is coming

ldquoDodd-Frank and the Myth of ldquoInterconnectednessrdquo by Peter J Wallison American Enterprise Institute Wall Street Journal Friday Feb 10 2012

ldquoTherersquos no evidence that exposure to Lehman imperiled other banks So why base a law on that premiserdquo (Ignores AIGderivatives-DKR)

Real separation of investment banking from commercial banking (return to simple Glass-Steagall type laws strong Volcker rules no proprietary trading by banks)

Breaking up the banks (seen as crucial by Simon Johnson MIT prof former chief economist of the IMF)

Reduce the size of financial derivative transactions and contracts outstanding There were proposals to tax them in the EU (OTC notional value is $708 trillion as of 611)

Limiting international financial network connectivity capital movements temporarily ldquocircuit breakersrdquo like in the stock market (NYSE) currently (Helbing Stiglitz)

The euro Robert Mundellrsquos theory calls for factor mobility in optimal currency areas

hellipThat includes capital mobility

Yet capital mobility may be a transmitting factor in financial networks that have by now reached a tipping pointhellip Mundell considers fixed exchange rates a stabilizing factor for global financial markets Obsolete view

ROBERT MUNDELL

Professor Robert Mundell 1999 Nobel Laureate the father of the Theory of Optimum Currency Areas

NOBEL PRIZE 1999

A Theory of Optimal Currency Areas (1958-1961) ldquofather of the eurordquo

(proposed ldquoeuropardquo in 1969) For the Mundell-Fleming

model which integrated the domestic and international sides of an economy (1958-1961) new policy guide

Should central banks adopt a more discretionary monetary (and regulatory) policy to head off speculative bubbles

They now operate mainly with inflation

targeting rules Ben Bernanke wants to make such a rule official at the Federal Reserve (itrsquos now informal) this is opposite of discretion

Emphatic yes we already find game theory in our introductory textbooks

Important to put the 2008 and eurozone financial crises in perspective We live in a globalized society and economy

Make students aware of the emerging complex systems perspectives and tools being developed Tipping points systemic riskshellip these are central concepts now Will be in textbooks So we should be aware of these trends too

Harvard University Northwestern University (NetLogo) University of Chicago (Booth School) NYU MIT Columbia U (in sociology economics) Cornell (mathematics small world networks) The Santa Fe Institute US Military Academy Also the New York Fed There are others this is a rapidly growing list

1 Globalization means interconnectedness

2 Interconnectedness is changing economic and social relations in profound ways not well understood but easy to observe

3 Dynamic and diverse agent interactions interconnected networks and their interactions with their environment can now result in tipping points that amplify shocks which then cascade throughout the system Roles of credit and bankruptcy crucial

4 Such spreading of systemic risks require an immediate and massive fiscal and monetary policy response Free market advocates greatly underestimate these effects 5 But the economy is less responsive in terms of growth and unemployment than before Okuns Law has become unstable (In 2008 and 2009 unemployment rose faster and higher than Okuns Law would indicate but recently unemployment is falling faster than the rate real GDP growth would normally be associated with)

6 Aggressive macro policies may not be sustainable they may create instability in the global monetary and financial architecture What should they be if changes in employment are no longer as clearly linked to changes in output

7 Systemic risks continue to be large proposed and likely regulatory regimes are nowhere near as significant as during the Great Depression Derivatives continue to hang over global finance and banking is becoming even more concentrated around the world

8 Macro models need to be overhauled to make them more useful as diagnostic tools and to point to directions for policy The interaction of heterogeneous agents and credit not money and interest rates need to play a more central role Economists need to understand banking and finance Mapping of financial networks might help policymakers better understand the risk and sources of shocks

9 Policy needs to be directed both toward the too big to fail and the too interconnected to fail problems

10 Such policies may create deadweight losses but such losses are much less than those from a phase transition and resulting global financial crisis with huge losses of wealth as seen in 20089 (Stiglitz)

11 Politics will stymie real reform until the next crisis in which case the risks of continued reliance on outmoded economic ideologies and models then aggressive monetary and fiscal measures in response to crisis will become even more clear

--the new science of networks (ldquomacrordquo or system-wide perspective) --dynamic agent-based systems (ldquomicrordquo or adaptive interaction of agents with environment perspective)

model which integrated the domestic and international sides of an economy (1958-1961) new policy guide

Should central banks adopt a more discretionary monetary (and regulatory) policy to head off speculative bubbles

They now operate mainly with inflation

targeting rules Ben Bernanke wants to make such a rule official at the Federal Reserve (itrsquos now informal) this is opposite of discretion

Emphatic yes we already find game theory in our introductory textbooks

Important to put the 2008 and eurozone financial crises in perspective We live in a globalized society and economy

Make students aware of the emerging complex systems perspectives and tools being developed Tipping points systemic riskshellip these are central concepts now Will be in textbooks So we should be aware of these trends too

Harvard University Northwestern University (NetLogo) University of Chicago (Booth School) NYU MIT Columbia U (in sociology economics) Cornell (mathematics small world networks) The Santa Fe Institute US Military Academy Also the New York Fed There are others this is a rapidly growing list

1 Globalization means interconnectedness

2 Interconnectedness is changing economic and social relations in profound ways not well understood but easy to observe

3 Dynamic and diverse agent interactions interconnected networks and their interactions with their environment can now result in tipping points that amplify shocks which then cascade throughout the system Roles of credit and bankruptcy crucial

4 Such spreading of systemic risks require an immediate and massive fiscal and monetary policy response Free market advocates greatly underestimate these effects 5 But the economy is less responsive in terms of growth and unemployment than before Okuns Law has become unstable (In 2008 and 2009 unemployment rose faster and higher than Okuns Law would indicate but recently unemployment is falling faster than the rate real GDP growth would normally be associated with)

6 Aggressive macro policies may not be sustainable they may create instability in the global monetary and financial architecture What should they be if changes in employment are no longer as clearly linked to changes in output

7 Systemic risks continue to be large proposed and likely regulatory regimes are nowhere near as significant as during the Great Depression Derivatives continue to hang over global finance and banking is becoming even more concentrated around the world

8 Macro models need to be overhauled to make them more useful as diagnostic tools and to point to directions for policy The interaction of heterogeneous agents and credit not money and interest rates need to play a more central role Economists need to understand banking and finance Mapping of financial networks might help policymakers better understand the risk and sources of shocks

9 Policy needs to be directed both toward the too big to fail and the too interconnected to fail problems

10 Such policies may create deadweight losses but such losses are much less than those from a phase transition and resulting global financial crisis with huge losses of wealth as seen in 20089 (Stiglitz)

11 Politics will stymie real reform until the next crisis in which case the risks of continued reliance on outmoded economic ideologies and models then aggressive monetary and fiscal measures in response to crisis will become even more clear

--the new science of networks (ldquomacrordquo or system-wide perspective) --dynamic agent-based systems (ldquomicrordquo or adaptive interaction of agents with environment perspective)

Harvard University Northwestern University (NetLogo) University of Chicago (Booth School) NYU MIT Columbia U (in sociology economics) Cornell (mathematics small world networks) The Santa Fe Institute US Military Academy Also the New York Fed There are others this is a rapidly growing list

1 Globalization means interconnectedness

2 Interconnectedness is changing economic and social relations in profound ways not well understood but easy to observe

3 Dynamic and diverse agent interactions interconnected networks and their interactions with their environment can now result in tipping points that amplify shocks which then cascade throughout the system Roles of credit and bankruptcy crucial

4 Such spreading of systemic risks require an immediate and massive fiscal and monetary policy response Free market advocates greatly underestimate these effects 5 But the economy is less responsive in terms of growth and unemployment than before Okuns Law has become unstable (In 2008 and 2009 unemployment rose faster and higher than Okuns Law would indicate but recently unemployment is falling faster than the rate real GDP growth would normally be associated with)

6 Aggressive macro policies may not be sustainable they may create instability in the global monetary and financial architecture What should they be if changes in employment are no longer as clearly linked to changes in output

7 Systemic risks continue to be large proposed and likely regulatory regimes are nowhere near as significant as during the Great Depression Derivatives continue to hang over global finance and banking is becoming even more concentrated around the world

8 Macro models need to be overhauled to make them more useful as diagnostic tools and to point to directions for policy The interaction of heterogeneous agents and credit not money and interest rates need to play a more central role Economists need to understand banking and finance Mapping of financial networks might help policymakers better understand the risk and sources of shocks

9 Policy needs to be directed both toward the too big to fail and the too interconnected to fail problems

10 Such policies may create deadweight losses but such losses are much less than those from a phase transition and resulting global financial crisis with huge losses of wealth as seen in 20089 (Stiglitz)

11 Politics will stymie real reform until the next crisis in which case the risks of continued reliance on outmoded economic ideologies and models then aggressive monetary and fiscal measures in response to crisis will become even more clear

Real separation of investment banking from commercial banking (return to simple Glass-Steagall type laws strong Volcker rules no proprietary trading by banks)

Breaking up the banks (seen as crucial by Simon Johnson MIT prof former chief economist of the IMF)

Reduce the size of financial derivative transactions and contracts outstanding There were proposals to tax them in the EU (OTC notional value is $708 trillion as of 611)

Limiting international financial network connectivity capital movements temporarily ldquocircuit breakersrdquo like in the stock market (NYSE) currently (Helbing Stiglitz)

7 Systemic risks continue to be large proposed and likely regulatory regimes are nowhere near as significant as during the Great Depression Derivatives continue to hang over global finance and banking is becoming even more concentrated around the world

8 Macro models need to be overhauled to make them more useful as diagnostic tools and to point to directions for policy The interaction of heterogeneous agents and credit not money and interest rates need to play a more central role Economists need to understand banking and finance Mapping of financial networks might help policymakers better understand the risk and sources of shocks

9 Policy needs to be directed both toward the too big to fail and the too interconnected to fail problems

10 Such policies may create deadweight losses but such losses are much less than those from a phase transition and resulting global financial crisis with huge losses of wealth as seen in 20089 (Stiglitz)

They now operate mainly with inflation

Emphatic yes we already find game theory in our introductory textbooks

Harvard University Northwestern University (NetLogo) University of Chicago (Booth School) NYU MIT Columbia U (in sociology economics) Cornell (mathematics small world networks) The Santa Fe Institute US Military Academy Also the New York Fed There are others this is a rapidly growing list

1 Globalization means interconnectedness

2 Interconnectedness is changing economic and social relations in profound ways not well understood but easy to observe

3 Dynamic and diverse agent interactions interconnected networks and their interactions with their environment can now result in tipping points that amplify shocks which then cascade throughout the system Roles of credit and bankruptcy crucial

4 Such spreading of systemic risks require an immediate and massive fiscal and monetary policy response Free market advocates greatly underestimate these effects 5 But the economy is less responsive in terms of growth and unemployment than before Okuns Law has become unstable (In 2008 and 2009 unemployment rose faster and higher than Okuns Law would indicate but recently unemployment is falling faster than the rate real GDP growth would normally be associated with)

6 Aggressive macro policies may not be sustainable they may create instability in the global monetary and financial architecture What should they be if changes in employment are no longer as clearly linked to changes in output

7 Systemic risks continue to be large proposed and likely regulatory regimes are nowhere near as significant as during the Great Depression Derivatives continue to hang over global finance and banking is becoming even more concentrated around the world

8 Macro models need to be overhauled to make them more useful as diagnostic tools and to point to directions for policy The interaction of heterogeneous agents and credit not money and interest rates need to play a more central role Economists need to understand banking and finance Mapping of financial networks might help policymakers better understand the risk and sources of shocks

9 Policy needs to be directed both toward the too big to fail and the too interconnected to fail problems

10 Such policies may create deadweight losses but such losses are much less than those from a phase transition and resulting global financial crisis with huge losses of wealth as seen in 20089 (Stiglitz)

11 Politics will stymie real reform until the next crisis in which case the risks of continued reliance on outmoded economic ideologies and models then aggressive monetary and fiscal measures in response to crisis will become even more clear

They now operate mainly with inflation

Emphatic yes we already find game theory in our introductory textbooks

Harvard University Northwestern University (NetLogo) University of Chicago (Booth School) NYU MIT Columbia U (in sociology economics) Cornell (mathematics small world networks) The Santa Fe Institute US Military Academy Also the New York Fed There are others this is a rapidly growing list

1 Globalization means interconnectedness

2 Interconnectedness is changing economic and social relations in profound ways not well understood but easy to observe

3 Dynamic and diverse agent interactions interconnected networks and their interactions with their environment can now result in tipping points that amplify shocks which then cascade throughout the system Roles of credit and bankruptcy crucial

4 Such spreading of systemic risks require an immediate and massive fiscal and monetary policy response Free market advocates greatly underestimate these effects 5 But the economy is less responsive in terms of growth and unemployment than before Okuns Law has become unstable (In 2008 and 2009 unemployment rose faster and higher than Okuns Law would indicate but recently unemployment is falling faster than the rate real GDP growth would normally be associated with)

6 Aggressive macro policies may not be sustainable they may create instability in the global monetary and financial architecture What should they be if changes in employment are no longer as clearly linked to changes in output

7 Systemic risks continue to be large proposed and likely regulatory regimes are nowhere near as significant as during the Great Depression Derivatives continue to hang over global finance and banking is becoming even more concentrated around the world

8 Macro models need to be overhauled to make them more useful as diagnostic tools and to point to directions for policy The interaction of heterogeneous agents and credit not money and interest rates need to play a more central role Economists need to understand banking and finance Mapping of financial networks might help policymakers better understand the risk and sources of shocks

9 Policy needs to be directed both toward the too big to fail and the too interconnected to fail problems

10 Such policies may create deadweight losses but such losses are much less than those from a phase transition and resulting global financial crisis with huge losses of wealth as seen in 20089 (Stiglitz)

11 Politics will stymie real reform until the next crisis in which case the risks of continued reliance on outmoded economic ideologies and models then aggressive monetary and fiscal measures in response to crisis will become even more clear

model which integrated the domestic and international sides of an economy (1958-1961) new policy guide

Should central banks adopt a more discretionary monetary (and regulatory) policy to head off speculative bubbles

They now operate mainly with inflation

targeting rules Ben Bernanke wants to make such a rule official at the Federal Reserve (itrsquos now informal) this is opposite of discretion

Emphatic yes we already find game theory in our introductory textbooks

Important to put the 2008 and eurozone financial crises in perspective We live in a globalized society and economy

Harvard University Northwestern University (NetLogo) University of Chicago (Booth School) NYU MIT Columbia U (in sociology economics) Cornell (mathematics small world networks) The Santa Fe Institute US Military Academy Also the New York Fed There are others this is a rapidly growing list

1 Globalization means interconnectedness

2 Interconnectedness is changing economic and social relations in profound ways not well understood but easy to observe

3 Dynamic and diverse agent interactions interconnected networks and their interactions with their environment can now result in tipping points that amplify shocks which then cascade throughout the system Roles of credit and bankruptcy crucial

4 Such spreading of systemic risks require an immediate and massive fiscal and monetary policy response Free market advocates greatly underestimate these effects 5 But the economy is less responsive in terms of growth and unemployment than before Okuns Law has become unstable (In 2008 and 2009 unemployment rose faster and higher than Okuns Law would indicate but recently unemployment is falling faster than the rate real GDP growth would normally be associated with)

6 Aggressive macro policies may not be sustainable they may create instability in the global monetary and financial architecture What should they be if changes in employment are no longer as clearly linked to changes in output

7 Systemic risks continue to be large proposed and likely regulatory regimes are nowhere near as significant as during the Great Depression Derivatives continue to hang over global finance and banking is becoming even more concentrated around the world

8 Macro models need to be overhauled to make them more useful as diagnostic tools and to point to directions for policy The interaction of heterogeneous agents and credit not money and interest rates need to play a more central role Economists need to understand banking and finance Mapping of financial networks might help policymakers better understand the risk and sources of shocks

9 Policy needs to be directed both toward the too big to fail and the too interconnected to fail problems

10 Such policies may create deadweight losses but such losses are much less than those from a phase transition and resulting global financial crisis with huge losses of wealth as seen in 20089 (Stiglitz)

11 Politics will stymie real reform until the next crisis in which case the risks of continued reliance on outmoded economic ideologies and models then aggressive monetary and fiscal measures in response to crisis will become even more clear

(proposed ldquoeuropardquo in 1969) For the Mundell-Fleming

model which integrated the domestic and international sides of an economy (1958-1961) new policy guide

Should central banks adopt a more discretionary monetary (and regulatory) policy to head off speculative bubbles

They now operate mainly with inflation

targeting rules Ben Bernanke wants to make such a rule official at the Federal Reserve (itrsquos now informal) this is opposite of discretion

Emphatic yes we already find game theory in our introductory textbooks

Important to put the 2008 and eurozone financial crises in perspective We live in a globalized society and economy

Make students aware of the emerging complex systems perspectives and tools being developed Tipping points systemic riskshellip these are central concepts now Will be in textbooks So we should be aware of these trends too

Harvard University Northwestern University (NetLogo) University of Chicago (Booth School) NYU MIT Columbia U (in sociology economics) Cornell (mathematics small world networks) The Santa Fe Institute US Military Academy Also the New York Fed There are others this is a rapidly growing list

1 Globalization means interconnectedness

2 Interconnectedness is changing economic and social relations in profound ways not well understood but easy to observe

3 Dynamic and diverse agent interactions interconnected networks and their interactions with their environment can now result in tipping points that amplify shocks which then cascade throughout the system Roles of credit and bankruptcy crucial

4 Such spreading of systemic risks require an immediate and massive fiscal and monetary policy response Free market advocates greatly underestimate these effects 5 But the economy is less responsive in terms of growth and unemployment than before Okuns Law has become unstable (In 2008 and 2009 unemployment rose faster and higher than Okuns Law would indicate but recently unemployment is falling faster than the rate real GDP growth would normally be associated with)

6 Aggressive macro policies may not be sustainable they may create instability in the global monetary and financial architecture What should they be if changes in employment are no longer as clearly linked to changes in output

7 Systemic risks continue to be large proposed and likely regulatory regimes are nowhere near as significant as during the Great Depression Derivatives continue to hang over global finance and banking is becoming even more concentrated around the world

8 Macro models need to be overhauled to make them more useful as diagnostic tools and to point to directions for policy The interaction of heterogeneous agents and credit not money and interest rates need to play a more central role Economists need to understand banking and finance Mapping of financial networks might help policymakers better understand the risk and sources of shocks

9 Policy needs to be directed both toward the too big to fail and the too interconnected to fail problems

10 Such policies may create deadweight losses but such losses are much less than those from a phase transition and resulting global financial crisis with huge losses of wealth as seen in 20089 (Stiglitz)

11 Politics will stymie real reform until the next crisis in which case the risks of continued reliance on outmoded economic ideologies and models then aggressive monetary and fiscal measures in response to crisis will become even more clear

ROBERT MUNDELL

Professor Robert Mundell 1999 Nobel Laureate the father of the Theory of Optimum Currency Areas

NOBEL PRIZE 1999

A Theory of Optimal Currency Areas (1958-1961) ldquofather of the eurordquo

(proposed ldquoeuropardquo in 1969) For the Mundell-Fleming

model which integrated the domestic and international sides of an economy (1958-1961) new policy guide

Should central banks adopt a more discretionary monetary (and regulatory) policy to head off speculative bubbles

They now operate mainly with inflation

targeting rules Ben Bernanke wants to make such a rule official at the Federal Reserve (itrsquos now informal) this is opposite of discretion

Emphatic yes we already find game theory in our introductory textbooks

Important to put the 2008 and eurozone financial crises in perspective We live in a globalized society and economy

Make students aware of the emerging complex systems perspectives and tools being developed Tipping points systemic riskshellip these are central concepts now Will be in textbooks So we should be aware of these trends too

Harvard University Northwestern University (NetLogo) University of Chicago (Booth School) NYU MIT Columbia U (in sociology economics) Cornell (mathematics small world networks) The Santa Fe Institute US Military Academy Also the New York Fed There are others this is a rapidly growing list

1 Globalization means interconnectedness

2 Interconnectedness is changing economic and social relations in profound ways not well understood but easy to observe

3 Dynamic and diverse agent interactions interconnected networks and their interactions with their environment can now result in tipping points that amplify shocks which then cascade throughout the system Roles of credit and bankruptcy crucial

4 Such spreading of systemic risks require an immediate and massive fiscal and monetary policy response Free market advocates greatly underestimate these effects 5 But the economy is less responsive in terms of growth and unemployment than before Okuns Law has become unstable (In 2008 and 2009 unemployment rose faster and higher than Okuns Law would indicate but recently unemployment is falling faster than the rate real GDP growth would normally be associated with)

6 Aggressive macro policies may not be sustainable they may create instability in the global monetary and financial architecture What should they be if changes in employment are no longer as clearly linked to changes in output

7 Systemic risks continue to be large proposed and likely regulatory regimes are nowhere near as significant as during the Great Depression Derivatives continue to hang over global finance and banking is becoming even more concentrated around the world

8 Macro models need to be overhauled to make them more useful as diagnostic tools and to point to directions for policy The interaction of heterogeneous agents and credit not money and interest rates need to play a more central role Economists need to understand banking and finance Mapping of financial networks might help policymakers better understand the risk and sources of shocks

9 Policy needs to be directed both toward the too big to fail and the too interconnected to fail problems

10 Such policies may create deadweight losses but such losses are much less than those from a phase transition and resulting global financial crisis with huge losses of wealth as seen in 20089 (Stiglitz)

11 Politics will stymie real reform until the next crisis in which case the risks of continued reliance on outmoded economic ideologies and models then aggressive monetary and fiscal measures in response to crisis will become even more clear

A Theory of Optimal Currency Areas (1958-1961) ldquofather of the eurordquo

(proposed ldquoeuropardquo in 1969) For the Mundell-Fleming

model which integrated the domestic and international sides of an economy (1958-1961) new policy guide

Should central banks adopt a more discretionary monetary (and regulatory) policy to head off speculative bubbles

They now operate mainly with inflation

targeting rules Ben Bernanke wants to make such a rule official at the Federal Reserve (itrsquos now informal) this is opposite of discretion

Emphatic yes we already find game theory in our introductory textbooks

Important to put the 2008 and eurozone financial crises in perspective We live in a globalized society and economy

Make students aware of the emerging complex systems perspectives and tools being developed Tipping points systemic riskshellip these are central concepts now Will be in textbooks So we should be aware of these trends too

Harvard University Northwestern University (NetLogo) University of Chicago (Booth School) NYU MIT Columbia U (in sociology economics) Cornell (mathematics small world networks) The Santa Fe Institute US Military Academy Also the New York Fed There are others this is a rapidly growing list

1 Globalization means interconnectedness

2 Interconnectedness is changing economic and social relations in profound ways not well understood but easy to observe

3 Dynamic and diverse agent interactions interconnected networks and their interactions with their environment can now result in tipping points that amplify shocks which then cascade throughout the system Roles of credit and bankruptcy crucial

4 Such spreading of systemic risks require an immediate and massive fiscal and monetary policy response Free market advocates greatly underestimate these effects 5 But the economy is less responsive in terms of growth and unemployment than before Okuns Law has become unstable (In 2008 and 2009 unemployment rose faster and higher than Okuns Law would indicate but recently unemployment is falling faster than the rate real GDP growth would normally be associated with)

6 Aggressive macro policies may not be sustainable they may create instability in the global monetary and financial architecture What should they be if changes in employment are no longer as clearly linked to changes in output

7 Systemic risks continue to be large proposed and likely regulatory regimes are nowhere near as significant as during the Great Depression Derivatives continue to hang over global finance and banking is becoming even more concentrated around the world

8 Macro models need to be overhauled to make them more useful as diagnostic tools and to point to directions for policy The interaction of heterogeneous agents and credit not money and interest rates need to play a more central role Economists need to understand banking and finance Mapping of financial networks might help policymakers better understand the risk and sources of shocks

9 Policy needs to be directed both toward the too big to fail and the too interconnected to fail problems

10 Such policies may create deadweight losses but such losses are much less than those from a phase transition and resulting global financial crisis with huge losses of wealth as seen in 20089 (Stiglitz)

11 Politics will stymie real reform until the next crisis in which case the risks of continued reliance on outmoded economic ideologies and models then aggressive monetary and fiscal measures in response to crisis will become even more clear

ldquoWith fluctuations in the supply of credit being at the center of many economic fluctuations a theory that has little to say about credit and its determinants is obviously of limited userdquo --standard models assume shocks are exogenous Stiglitz indicates that they are now often man-made endogenous ldquothe sub-prime mortgage crisis was man-maderdquo (p 596 Rethinking Macroeconomics)

ldquohellipStandard Models focusing on money not credit where banks and security markets were not well analyzed provided little guidance on how government could restore the flow of credit Thatmdashnot interest ratesmdashwas the central issuerdquo (p609) RETHINKING MACROECONOMICS WHAT FAILED AND HOW TO REPAIR IT Joseph Stiglitz Journal of the European Economic Association August 2011

ldquoMacro models agree that optimal monetary policy is to keep interest rates low to avoid sectoral misallocationrdquo

Stiglitz argues otherwise puts him ironically on the same page as the Austrian economists icons of the Tea Partyists and Rep Ron Paul Thatrsquos a revolution

ldquoWhile the economic system sometimes amplifies shocks standard theory argues that economic systems do just the opposite through several mechanismsrdquo ldquoUnderstanding amplificationmdashhow small disturbances can give rise to large effectsmdashshould be one of the key objectives of macroeconomic researchrdquo ldquohellipeconomic systems (viewed as complex adaptive processes) may exhibit major phase transitionsrdquo This is where the revolution in macroeconomics is coming

ldquoDodd-Frank and the Myth of ldquoInterconnectednessrdquo by Peter J Wallison American Enterprise Institute Wall Street Journal Friday Feb 10 2012

ldquoTherersquos no evidence that exposure to Lehman imperiled other banks So why base a law on that premiserdquo (Ignores AIGderivatives-DKR)

Real separation of investment banking from commercial banking (return to simple Glass-Steagall type laws strong Volcker rules no proprietary trading by banks)

Breaking up the banks (seen as crucial by Simon Johnson MIT prof former chief economist of the IMF)

Reduce the size of financial derivative transactions and contracts outstanding There were proposals to tax them in the EU (OTC notional value is $708 trillion as of 611)

Limiting international financial network connectivity capital movements temporarily ldquocircuit breakersrdquo like in the stock market (NYSE) currently (Helbing Stiglitz)

The euro Robert Mundellrsquos theory calls for factor mobility in optimal currency areas

hellipThat includes capital mobility

Yet capital mobility may be a transmitting factor in financial networks that have by now reached a tipping pointhellip Mundell considers fixed exchange rates a stabilizing factor for global financial markets Obsolete view

ROBERT MUNDELL

Professor Robert Mundell 1999 Nobel Laureate the father of the Theory of Optimum Currency Areas

NOBEL PRIZE 1999

A Theory of Optimal Currency Areas (1958-1961) ldquofather of the eurordquo

(proposed ldquoeuropardquo in 1969) For the Mundell-Fleming

model which integrated the domestic and international sides of an economy (1958-1961) new policy guide

Should central banks adopt a more discretionary monetary (and regulatory) policy to head off speculative bubbles

They now operate mainly with inflation

targeting rules Ben Bernanke wants to make such a rule official at the Federal Reserve (itrsquos now informal) this is opposite of discretion

Emphatic yes we already find game theory in our introductory textbooks

Important to put the 2008 and eurozone financial crises in perspective We live in a globalized society and economy

Make students aware of the emerging complex systems perspectives and tools being developed Tipping points systemic riskshellip these are central concepts now Will be in textbooks So we should be aware of these trends too

Harvard University Northwestern University (NetLogo) University of Chicago (Booth School) NYU MIT Columbia U (in sociology economics) Cornell (mathematics small world networks) The Santa Fe Institute US Military Academy Also the New York Fed There are others this is a rapidly growing list

1 Globalization means interconnectedness

2 Interconnectedness is changing economic and social relations in profound ways not well understood but easy to observe

3 Dynamic and diverse agent interactions interconnected networks and their interactions with their environment can now result in tipping points that amplify shocks which then cascade throughout the system Roles of credit and bankruptcy crucial

4 Such spreading of systemic risks require an immediate and massive fiscal and monetary policy response Free market advocates greatly underestimate these effects 5 But the economy is less responsive in terms of growth and unemployment than before Okuns Law has become unstable (In 2008 and 2009 unemployment rose faster and higher than Okuns Law would indicate but recently unemployment is falling faster than the rate real GDP growth would normally be associated with)

6 Aggressive macro policies may not be sustainable they may create instability in the global monetary and financial architecture What should they be if changes in employment are no longer as clearly linked to changes in output

7 Systemic risks continue to be large proposed and likely regulatory regimes are nowhere near as significant as during the Great Depression Derivatives continue to hang over global finance and banking is becoming even more concentrated around the world

8 Macro models need to be overhauled to make them more useful as diagnostic tools and to point to directions for policy The interaction of heterogeneous agents and credit not money and interest rates need to play a more central role Economists need to understand banking and finance Mapping of financial networks might help policymakers better understand the risk and sources of shocks

9 Policy needs to be directed both toward the too big to fail and the too interconnected to fail problems

10 Such policies may create deadweight losses but such losses are much less than those from a phase transition and resulting global financial crisis with huge losses of wealth as seen in 20089 (Stiglitz)

11 Politics will stymie real reform until the next crisis in which case the risks of continued reliance on outmoded economic ideologies and models then aggressive monetary and fiscal measures in response to crisis will become even more clear

--the new science of networks (ldquomacrordquo or system-wide perspective) --dynamic agent-based systems (ldquomicrordquo or adaptive interaction of agents with environment perspective)

ldquoWe believe that it will be necessary for supervisory authorities to develop a perspective on the network aspects of the financial system collect appropriate data define measures of connectivity and perform macro stress testing at the system level In this way new measures of financial fragility would be obtainedrdquo

ldquoWith fluctuations in the supply of credit being at the center of many economic fluctuations a theory that has little to say about credit and its determinants is obviously of limited userdquo --standard models assume shocks are exogenous Stiglitz indicates that they are now often man-made endogenous ldquothe sub-prime mortgage crisis was man-maderdquo (p 596 Rethinking Macroeconomics)

ldquohellipStandard Models focusing on money not credit where banks and security markets were not well analyzed provided little guidance on how government could restore the flow of credit Thatmdashnot interest ratesmdashwas the central issuerdquo (p609) RETHINKING MACROECONOMICS WHAT FAILED AND HOW TO REPAIR IT Joseph Stiglitz Journal of the European Economic Association August 2011

ldquoMacro models agree that optimal monetary policy is to keep interest rates low to avoid sectoral misallocationrdquo

Stiglitz argues otherwise puts him ironically on the same page as the Austrian economists icons of the Tea Partyists and Rep Ron Paul Thatrsquos a revolution

ldquoWhile the economic system sometimes amplifies shocks standard theory argues that economic systems do just the opposite through several mechanismsrdquo ldquoUnderstanding amplificationmdashhow small disturbances can give rise to large effectsmdashshould be one of the key objectives of macroeconomic researchrdquo ldquohellipeconomic systems (viewed as complex adaptive processes) may exhibit major phase transitionsrdquo This is where the revolution in macroeconomics is coming

ldquoDodd-Frank and the Myth of ldquoInterconnectednessrdquo by Peter J Wallison American Enterprise Institute Wall Street Journal Friday Feb 10 2012

ldquoTherersquos no evidence that exposure to Lehman imperiled other banks So why base a law on that premiserdquo (Ignores AIGderivatives-DKR)

Real separation of investment banking from commercial banking (return to simple Glass-Steagall type laws strong Volcker rules no proprietary trading by banks)

Breaking up the banks (seen as crucial by Simon Johnson MIT prof former chief economist of the IMF)

Reduce the size of financial derivative transactions and contracts outstanding There were proposals to tax them in the EU (OTC notional value is $708 trillion as of 611)

Limiting international financial network connectivity capital movements temporarily ldquocircuit breakersrdquo like in the stock market (NYSE) currently (Helbing Stiglitz)

The euro Robert Mundellrsquos theory calls for factor mobility in optimal currency areas

hellipThat includes capital mobility

Yet capital mobility may be a transmitting factor in financial networks that have by now reached a tipping pointhellip Mundell considers fixed exchange rates a stabilizing factor for global financial markets Obsolete view

ROBERT MUNDELL

Professor Robert Mundell 1999 Nobel Laureate the father of the Theory of Optimum Currency Areas

NOBEL PRIZE 1999

A Theory of Optimal Currency Areas (1958-1961) ldquofather of the eurordquo

(proposed ldquoeuropardquo in 1969) For the Mundell-Fleming

model which integrated the domestic and international sides of an economy (1958-1961) new policy guide

Should central banks adopt a more discretionary monetary (and regulatory) policy to head off speculative bubbles

They now operate mainly with inflation

targeting rules Ben Bernanke wants to make such a rule official at the Federal Reserve (itrsquos now informal) this is opposite of discretion

Emphatic yes we already find game theory in our introductory textbooks

Important to put the 2008 and eurozone financial crises in perspective We live in a globalized society and economy

Make students aware of the emerging complex systems perspectives and tools being developed Tipping points systemic riskshellip these are central concepts now Will be in textbooks So we should be aware of these trends too

Harvard University Northwestern University (NetLogo) University of Chicago (Booth School) NYU MIT Columbia U (in sociology economics) Cornell (mathematics small world networks) The Santa Fe Institute US Military Academy Also the New York Fed There are others this is a rapidly growing list

1 Globalization means interconnectedness

2 Interconnectedness is changing economic and social relations in profound ways not well understood but easy to observe

3 Dynamic and diverse agent interactions interconnected networks and their interactions with their environment can now result in tipping points that amplify shocks which then cascade throughout the system Roles of credit and bankruptcy crucial

4 Such spreading of systemic risks require an immediate and massive fiscal and monetary policy response Free market advocates greatly underestimate these effects 5 But the economy is less responsive in terms of growth and unemployment than before Okuns Law has become unstable (In 2008 and 2009 unemployment rose faster and higher than Okuns Law would indicate but recently unemployment is falling faster than the rate real GDP growth would normally be associated with)

6 Aggressive macro policies may not be sustainable they may create instability in the global monetary and financial architecture What should they be if changes in employment are no longer as clearly linked to changes in output

7 Systemic risks continue to be large proposed and likely regulatory regimes are nowhere near as significant as during the Great Depression Derivatives continue to hang over global finance and banking is becoming even more concentrated around the world

8 Macro models need to be overhauled to make them more useful as diagnostic tools and to point to directions for policy The interaction of heterogeneous agents and credit not money and interest rates need to play a more central role Economists need to understand banking and finance Mapping of financial networks might help policymakers better understand the risk and sources of shocks

9 Policy needs to be directed both toward the too big to fail and the too interconnected to fail problems

10 Such policies may create deadweight losses but such losses are much less than those from a phase transition and resulting global financial crisis with huge losses of wealth as seen in 20089 (Stiglitz)

11 Politics will stymie real reform until the next crisis in which case the risks of continued reliance on outmoded economic ideologies and models then aggressive monetary and fiscal measures in response to crisis will become even more clear

--the new science of networks (ldquomacrordquo or system-wide perspective) --dynamic agent-based systems (ldquomicrordquo or adaptive interaction of agents with environment perspective)

ldquoDodd-Frank and the Myth of ldquoInterconnectednessrdquo by Peter J Wallison American Enterprise Institute Wall Street Journal Friday Feb 10 2012

ldquoTherersquos no evidence that exposure to Lehman imperiled other banks So why base a law on that premiserdquo (Ignores AIGderivatives-DKR)

Real separation of investment banking from commercial banking (return to simple Glass-Steagall type laws strong Volcker rules no proprietary trading by banks)

Breaking up the banks (seen as crucial by Simon Johnson MIT prof former chief economist of the IMF)

Reduce the size of financial derivative transactions and contracts outstanding There were proposals to tax them in the EU (OTC notional value is $708 trillion as of 611)

Limiting international financial network connectivity capital movements temporarily ldquocircuit breakersrdquo like in the stock market (NYSE) currently (Helbing Stiglitz)

The euro Robert Mundellrsquos theory calls for factor mobility in optimal currency areas

hellipThat includes capital mobility

Yet capital mobility may be a transmitting factor in financial networks that have by now reached a tipping pointhellip Mundell considers fixed exchange rates a stabilizing factor for global financial markets Obsolete view

ROBERT MUNDELL

Professor Robert Mundell 1999 Nobel Laureate the father of the Theory of Optimum Currency Areas

NOBEL PRIZE 1999

A Theory of Optimal Currency Areas (1958-1961) ldquofather of the eurordquo

(proposed ldquoeuropardquo in 1969) For the Mundell-Fleming

model which integrated the domestic and international sides of an economy (1958-1961) new policy guide

Should central banks adopt a more discretionary monetary (and regulatory) policy to head off speculative bubbles

They now operate mainly with inflation

targeting rules Ben Bernanke wants to make such a rule official at the Federal Reserve (itrsquos now informal) this is opposite of discretion

Emphatic yes we already find game theory in our introductory textbooks

Important to put the 2008 and eurozone financial crises in perspective We live in a globalized society and economy

Make students aware of the emerging complex systems perspectives and tools being developed Tipping points systemic riskshellip these are central concepts now Will be in textbooks So we should be aware of these trends too

Harvard University Northwestern University (NetLogo) University of Chicago (Booth School) NYU MIT Columbia U (in sociology economics) Cornell (mathematics small world networks) The Santa Fe Institute US Military Academy Also the New York Fed There are others this is a rapidly growing list

1 Globalization means interconnectedness

2 Interconnectedness is changing economic and social relations in profound ways not well understood but easy to observe

3 Dynamic and diverse agent interactions interconnected networks and their interactions with their environment can now result in tipping points that amplify shocks which then cascade throughout the system Roles of credit and bankruptcy crucial

4 Such spreading of systemic risks require an immediate and massive fiscal and monetary policy response Free market advocates greatly underestimate these effects 5 But the economy is less responsive in terms of growth and unemployment than before Okuns Law has become unstable (In 2008 and 2009 unemployment rose faster and higher than Okuns Law would indicate but recently unemployment is falling faster than the rate real GDP growth would normally be associated with)

6 Aggressive macro policies may not be sustainable they may create instability in the global monetary and financial architecture What should they be if changes in employment are no longer as clearly linked to changes in output

7 Systemic risks continue to be large proposed and likely regulatory regimes are nowhere near as significant as during the Great Depression Derivatives continue to hang over global finance and banking is becoming even more concentrated around the world

8 Macro models need to be overhauled to make them more useful as diagnostic tools and to point to directions for policy The interaction of heterogeneous agents and credit not money and interest rates need to play a more central role Economists need to understand banking and finance Mapping of financial networks might help policymakers better understand the risk and sources of shocks

9 Policy needs to be directed both toward the too big to fail and the too interconnected to fail problems

10 Such policies may create deadweight losses but such losses are much less than those from a phase transition and resulting global financial crisis with huge losses of wealth as seen in 20089 (Stiglitz)

11 Politics will stymie real reform until the next crisis in which case the risks of continued reliance on outmoded economic ideologies and models then aggressive monetary and fiscal measures in response to crisis will become even more clear

ROBERT MUNDELL

Professor Robert Mundell 1999 Nobel Laureate the father of the Theory of Optimum Currency Areas

NOBEL PRIZE 1999

A Theory of Optimal Currency Areas (1958-1961) ldquofather of the eurordquo

(proposed ldquoeuropardquo in 1969) For the Mundell-Fleming

model which integrated the domestic and international sides of an economy (1958-1961) new policy guide

Should central banks adopt a more discretionary monetary (and regulatory) policy to head off speculative bubbles

They now operate mainly with inflation

targeting rules Ben Bernanke wants to make such a rule official at the Federal Reserve (itrsquos now informal) this is opposite of discretion

Emphatic yes we already find game theory in our introductory textbooks

Important to put the 2008 and eurozone financial crises in perspective We live in a globalized society and economy

Make students aware of the emerging complex systems perspectives and tools being developed Tipping points systemic riskshellip these are central concepts now Will be in textbooks So we should be aware of these trends too

Harvard University Northwestern University (NetLogo) University of Chicago (Booth School) NYU MIT Columbia U (in sociology economics) Cornell (mathematics small world networks) The Santa Fe Institute US Military Academy Also the New York Fed There are others this is a rapidly growing list

1 Globalization means interconnectedness

2 Interconnectedness is changing economic and social relations in profound ways not well understood but easy to observe

3 Dynamic and diverse agent interactions interconnected networks and their interactions with their environment can now result in tipping points that amplify shocks which then cascade throughout the system Roles of credit and bankruptcy crucial

4 Such spreading of systemic risks require an immediate and massive fiscal and monetary policy response Free market advocates greatly underestimate these effects 5 But the economy is less responsive in terms of growth and unemployment than before Okuns Law has become unstable (In 2008 and 2009 unemployment rose faster and higher than Okuns Law would indicate but recently unemployment is falling faster than the rate real GDP growth would normally be associated with)

6 Aggressive macro policies may not be sustainable they may create instability in the global monetary and financial architecture What should they be if changes in employment are no longer as clearly linked to changes in output

7 Systemic risks continue to be large proposed and likely regulatory regimes are nowhere near as significant as during the Great Depression Derivatives continue to hang over global finance and banking is becoming even more concentrated around the world

8 Macro models need to be overhauled to make them more useful as diagnostic tools and to point to directions for policy The interaction of heterogeneous agents and credit not money and interest rates need to play a more central role Economists need to understand banking and finance Mapping of financial networks might help policymakers better understand the risk and sources of shocks

9 Policy needs to be directed both toward the too big to fail and the too interconnected to fail problems

10 Such policies may create deadweight losses but such losses are much less than those from a phase transition and resulting global financial crisis with huge losses of wealth as seen in 20089 (Stiglitz)

11 Politics will stymie real reform until the next crisis in which case the risks of continued reliance on outmoded economic ideologies and models then aggressive monetary and fiscal measures in response to crisis will become even more clear

--the new science of networks (ldquomacrordquo or system-wide perspective) --dynamic agent-based systems (ldquomicrordquo or adaptive interaction of agents with environment perspective)

1 Globalization means interconnectedness

2 Interconnectedness is changing economic and social relations in profound ways not well understood but easy to observe

3 Dynamic and diverse agent interactions interconnected networks and their interactions with their environment can now result in tipping points that amplify shocks which then cascade throughout the system Roles of credit and bankruptcy crucial

4 Such spreading of systemic risks require an immediate and massive fiscal and monetary policy response Free market advocates greatly underestimate these effects 5 But the economy is less responsive in terms of growth and unemployment than before Okuns Law has become unstable (In 2008 and 2009 unemployment rose faster and higher than Okuns Law would indicate but recently unemployment is falling faster than the rate real GDP growth would normally be associated with)

6 Aggressive macro policies may not be sustainable they may create instability in the global monetary and financial architecture What should they be if changes in employment are no longer as clearly linked to changes in output

7 Systemic risks continue to be large proposed and likely regulatory regimes are nowhere near as significant as during the Great Depression Derivatives continue to hang over global finance and banking is becoming even more concentrated around the world

8 Macro models need to be overhauled to make them more useful as diagnostic tools and to point to directions for policy The interaction of heterogeneous agents and credit not money and interest rates need to play a more central role Economists need to understand banking and finance Mapping of financial networks might help policymakers better understand the risk and sources of shocks

9 Policy needs to be directed both toward the too big to fail and the too interconnected to fail problems

10 Such policies may create deadweight losses but such losses are much less than those from a phase transition and resulting global financial crisis with huge losses of wealth as seen in 20089 (Stiglitz)

11 Politics will stymie real reform until the next crisis in which case the risks of continued reliance on outmoded economic ideologies and models then aggressive monetary and fiscal measures in response to crisis will become even more clear

6 Aggressive macro policies may not be sustainable they may create instability in the global monetary and financial architecture What should they be if changes in employment are no longer as clearly linked to changes in output

7 Systemic risks continue to be large proposed and likely regulatory regimes are nowhere near as significant as during the Great Depression Derivatives continue to hang over global finance and banking is becoming even more concentrated around the world

8 Macro models need to be overhauled to make them more useful as diagnostic tools and to point to directions for policy The interaction of heterogeneous agents and credit not money and interest rates need to play a more central role Economists need to understand banking and finance Mapping of financial networks might help policymakers better understand the risk and sources of shocks

9 Policy needs to be directed both toward the too big to fail and the too interconnected to fail problems

10 Such policies may create deadweight losses but such losses are much less than those from a phase transition and resulting global financial crisis with huge losses of wealth as seen in 20089 (Stiglitz)

11 Politics will stymie real reform until the next crisis in which case the risks of continued reliance on outmoded economic ideologies and models then aggressive monetary and fiscal measures in response to crisis will become even more clear
