Measuring economic performance
GDP = value of final goods and services produced domestically GDP per person -- or per worker, per labor hour, per life Market exchange rates, or purchasing-power-parity rates Comparing commodity bundles across nations Measuring non-market public and private production
Real GDP adjusts for changes in general price level Accounting for quality change and new products
Other indicators Unemployment Inflation Inequality Extent of business cycles (instability) Health Longevity Environment Freedom
Data for 1995 United States Japan
GDP $7,415.7 billion 483.22 trillion yen N (population) 267 million 125 million GDP/N $27,774 3,866 thousand yen
Use market exchange rate of 94 yen/$1 to compare:
GDP/N $27,774 $41,128 Japan 48% above US!_______________________________________________________________
Big Mac $2.00 340 yen PPP exchange rate is 170 yen/$1 (yen is over-valued)
GDP/N at PPP $27,774 $22,741 Japan 18% below US
Real GDP/N in Big Macs 13,887 11,371
Data for 1995 United States Japan
GDP/N at PPP $27,774 $22,741 Japan 18% below US
GDP/E at PPP $55,334 $42,838 Japan 23% below US
CONS/N at PPP $18,800 $11,691 Japan 38% below US
Life expectancy (years) 77.2 81.8 Japan 34% below US in lifetime consumption

Broader Measures of Performance
Human Development Index
United Nations, Human Development Report
HDI is average of three indexes:
Life expectancy index
Education index = (2/3)*ALI + (1/3)*GEIALI = Adult literacy rate indexGEI = Combined gross enrollment index
GDP per capita index
Broader Measures of Performance
Gallop World Poll
Asks people about satisfaction with personal life and nation
On a scale of 0-10, from worst to best possible life for you:Where do you feel you stand?Where did you stand 5 years ago?Where do you expect to stand 5 years from now?
Same questions for country rather than for selfOptimism = outlook for 5 years hence – present
See Nestor Gandelman and Ruben Hernandez-Murillo,“The Impact of Inflation and Unemployment on Subjective
Personal and Country Evaluations”Federal Reserve Bank of St. Louis Review, May/June 2009

Broader Measures of Performance
Dashboard Concept
Interntional Commission on Measurement of Economic Performance and Social Progress (Joseph Stiglitz, Amartya Sen)
Speedometer alone not enough to steer car; need a dozen dials
State of the USA Project
National Academy of SciencesMulti-faceted, 300 or more indicators arranged by categoriesHealth care legislation calls for new body to administer Key National Indicators System web siteNot yet “live”
Sources of GDP Growth
Growth of factor s of productionLand (L), including natural resourcesLabor (N), adjusted for health, training, experienceCapital (K), i.e., equipment, commercial and residential structures
More efficient allocation of factors of production
Improvements in technology Techniques of productionManagement methodsMarketing and distribution methodsNew products
Sources of Growth in GDP per Capita (GDP/N)
N increases through population growthIncreases in N alone reduce GDP/N: diminishing returns
K increases through saving and investmentIncreases in K/N increase GDP/N, but less than in proportion
Improvements in efficiency through expansion of market (division of labor), competitive pressures, advances in technology
Improvements in technology through research, creative activity, entrepreneurial activity
Empirically, most GDP/N increase due to improvements in efficiency and technology

China’s Leadership in Technology before 1400
See Joel Mokyr’s The Lever of Riches
Examples of China’s technical advances:
Wet-field techniques for rice cultivationAdvances in other agricultural techniques -- iron plow, fertilizersTracts and handbooks to disseminate agricultural methodsBlast furnaces, iron castingSpinning wheel, driven by central powerHydraulic power, waterwheelAccurate water clocksMaritime technology – compass, large ocean-going junksPaper (money, wallpaper)WheelbarrowProcelains, lacquers, explosives, pharmaceuticalsHorse collar, crossbow
Why Did China Fail to Become Europe?
Population pressure required increases in agricultural productivity, not manufacturing
Chinese philosophy turned inward looking, stressed harmony with nature, not exploiting nature
Chinese failed to develop system of formal, deductive logic –no Galileo, Descartes, Newton, or Leibniz
Merchants did not rise to power in China; imperial bureaucracy dominant
Imperial court halts geographical exploration after 1430
Growing desire of traditional groups (government, e.g.,) in China to avoid social conflicts associated with technological changes
Netherlands Leadership: 17th to late 18th century
Reasons for success:Modern institutionsLand ownership by small proprietorsSmall nobilityNo church landReligious toleranceRational approach to problemsGeography - coast; mouths of major European riversMercantilist policiesBlocked Antwerp’s sea accessCaptured Asian and Latin American trade from PortugalEntrepôt trade (transshipment, warehousing)
Reasons Dutch dethroned:Loss of monopolies in trade in conflicts with France and UKCurrency became overvalued
Entrepôt trade makes banking center
United Kingdom: Late 18th to late 19th century
Dutch had highest productivity, but little productivity growth
Spurs to UK productivity growth:
Higher capital investment than Dutch
Promotion of free markets, international competition
Technical advances in cotton textiles, iron and steel, steam power, railways
Application of scientific principles, but why in UK? See Robert C. Allen, The British Industrial Revolution in Global Perspective
Property rights more secure in FranceItaly and Germany develop science of steam engineDutch were highly urbanized, higher literacy rate
Military demands of Royal Navy create demand for technologyDevelopment of patent systemHigh wages, cheap coal, consumer society
Reasons UK Dethroned
Did not explicitly foster education and technology
Capital stock grew slowly; savings available, but foreigninvestment as large as domestic
Diffused growth process to follower countries through freetrade, foreign investment, exportof technology
Currency became overvalued
US: Late 19th century to ?
US advantages
Abundant natural resources
High rates of investment (twice UK in 1890-1950), including public investment in infrastructure and education
Large, free domestic market fosters large companies enjoying scale economies, able to fund research
Protectionist trade policies, slavery
Position strengthened by two world wars
