Green Accounting, Growth, and other Measurement Issues

Peter Berck(c) 2010

18-1


How are we doing?

• National Income and Products Accounts are a balance sheet for a country.

• They are a measure of what happened this year.

• They are not an assets statement.

18-2


Firms

• Linked sheets– Assets on Jan 1

• Factories, inventory, cash, whatever

– Income from Jan1 – Dec 30• Revenue – cost of goods sold – etc

– Gives Assets on Dec 30

• We don’t do the assets part for countries, just the income part.

18-3


Gross Domestic Product

• Value of all final goods and services produced within a countries borders.

• Final goods are marketed to someone.– Candy bars. Final. Not used to make other

goods.– Steel. Intermediate. Used to make cars, a

final good. Believe that intermediate must be used up within the year.

– Cars, final.

18-4


Conservation Reserve

• Farmer is paid for land that grows birds ( a conservation use)– Birds are not marketed and hence not a final good.– Land payments to the farmers should be a final

good, but I doubt it is counted that way.

• SCR unit on a powerplant.– A final good (investment is a type of final good) and

not as an intermediate good.– Change in clean air is not valued.

18-5


So GDP

• Values things that make the planet better but not the change in the value of the planet itself.– SCR in GDP– Clean air not in GDP

• Be careful! If clean air were in GDP as a final good than we would need to reconsider how to handle SCR’s.

Table 18.1: U.S. National Income and Product Accounts for 2008 (in billions of dollars).


Three missing elements

• 1. Leisure. 37% to 66% of women in labor force. (1959-2004). GDP goes up because of the final product they now produce. GDP does not go down because of the unmarketed products they longer produce. (Hey, any of you parents? Do you find Leisure a strange name for what you produce when you are not at work…?)

18-8


Second Missing Element

• 2. Natural Resource Depletion.– When you build an SCR, it shows up in GDP.– About 1/30 of it shows up each year

thereafter as capital consumption and is subtracted from GDP to get NNP.

– When you take oil out of the ground, it shows up in GDP.

– Exactly 0% of it shows up each year as capital consumption.

18-9


And third

• Non-marketed goods.– Environmental services– Clean air

• Not a market good but final goods used to produce it are valued.

– Pollination• An intermediate good if ever there was one.

Properly excluded from GDP

18-10


What of education?

• It is a final good; an investment just like building a building or an SCR.

• It is included in GDP (usually as part of government, but private universities count too.)

• If it were treated as an asset, it should be depreciated! That is NNP is too big because we don’t account for strokes, death, forgetfullness, and leaving the labor force

18-11


Figure 18.1: Adjusted Net Savings and Its Components.


Figure 18.2: Human Development Index for Sweden, Brazil, Ethiopia, and India.


Why have an HDI?

• Is there more to be learned from HDI than from GDP?– Think of an oilopoly that stashes it cash in a

swiss bank account.– How about Cuba in its heyday with just

enough food and healthcare and lots of education?

18-14


Are Richer countries cleaner

• Maybe

18-15


Figure 18.3: Environmental Kuznets Curve for SOx.


Figure 18.4: Greenhouse Gas Emissions and U.S. Real GDP.


Why is China (or at least Beijing) getting cleaner?

• Physical answer: moving out polluting industry and even closing it. More mass transit. Controlling erosion. Etc.

• Economic Answer: Why? Hint: they are getting much more income over time.

18-18


Jobs and Environment

• US as a whole. Supply equals demand for labor. Makes no difference whether we make cars or Modern Dance instruction.

• CA. Isn’t it possible that we are so clean that no one can work here? All industry and people move to Texas?– But there is no evidence that this happens.

18-19


CDM

• Clean Development Mechanism– A project in a developing country that saves

carbon. Example: Better cement kiln in china.

– Carbon savings are sold to an EU country that has obligations under Kyoto/EU trading scheme.

– Additionality. Did the CDM do more than they would have done anyway?

18-20


CDM—emissions trading

• Works just like our emissions trading diagrams.– Do the cleanup where it is cheaper.

18-21


REDD/REDD+

• United Nations Collaborative Programme on Reducing Emissions from Deforestation and Forest Degradation in Developing Countries

• Same idea as CDM—except save carbon by keeping forests.– Verification is very, very hard.– Additionality is hard, too.

18-22


IPAT

• Impact = Pop * Cons/Pop * impact/cons– My view: The biggest and most important

pollution control project on the planet is the one child policy in China.• Policy is a real burden to average person.• Policy will save the pollution from perhaps a ½

billion people over the next 20 years.• Comparison: Nile river basin—Ethiopia at 80m

and 3% growth.
