State Income Accounting Measures Economic Activity Narrowly Defined

But this Measure misses many Aspects of Human Welfare

The Components of GSP
Gross State Product (GSP) is the sum of the following:• Consumption (C)
• Investment (I)
• Government Expenditures (G)
• Net Exports (NE)
GSP = C + I + G + NE

GSP to NSP to GNSP
Another measure is Net State Product, which deducts
capital depreciation from GSP NSP = C + I + G + NE – CD Green NSP measures environomy. From NSP, subtract
• Depreciation of natural capital (biodiversity, aquifers, reefs)
• Defensive expenditures (scrubbers on smokestacks to reduce pollution)» Falsely included in NSP in the first place
» Subtract again to better reflect net increase in welfare
• Residual damages from pollution, congestion, and ecological damages (flooding, sewage spills, leptospirosis)
GNSP = C + I + G + NE – CD – (NCD + 2DE + RPD)

Case study – Ko`olau forested watershed
Amenity NPV, in millions MethodGroundwater quantity $4570 Lost recharge
Water quality $83.7 – $394 Averted dredging costs
In-stream uses $82.4 Survey on single fish species
Species habitat $487 Survey on single bird species
Biodiversity $0.6 – $5.5 Average cost listing 11 Ko`olau plant species
Subsistence $34.7 Replacement value, pigs
Hunting $62.8 Hunting expenditures
Aesthetic values $1040 Survey
Commercial harvests $0.6 Koa harvest
Ecotourism $1000 Ecotourism expenditures
Climate control $82.2 Replacement cost, carbon sequestration
TOTAL $7.4 – $7.8 billion

Sustainable/Green Income Accounting
Would include depreciation of natural capital, pollution damages
Better indicator of levels-of-living, forward-looking welfare
GNSP reflects the performance of the environomy
