This paper combines theory with data from different domains to provide an empirical analysis of the scale and variability of social capital as wealth. The analysis is used to argue, given what has been learned from the literature on social capital, that the welfare returns to investing in trust...

The fact that developing countries do not have carbon emission caps under the Kyoto Protocol has led to the current interest in high-income countries in border taxes on the "virtual" carbon content of imports. The authors use Global Trade Analysis Project data and input-output analysis to...

Recent carbon market prices are substantially lower than mean or median estimates of the social cost of carbon in the literature. Intuition would therefore suggest that 'investment errors' are being made, in the sense that markets favor higher carbon-emitting projects, while global welfare would...

Since income is the return on wealth, the total wealth of any given country should be on the order of 20 times its gross domestic product. Instead the average observed ratio from the balance sheet accounts of the System of National Accounts is a factor of 2.6 to 6.6, depending on whether natural...

Biodiversity, a property of natural areas, provides a range of benefits to the economy including bioprospecting rents, knowledge and insurance, ecotourism fees, and ecosystem services. Many of these values can be broken out in the System of National Accounts, leading to better estimates of the...

Questions about the ultimate size of mineral and energy resource endowments and the degree of fiscal prudence which should be exercised by countries engaged in resource extraction have become central for many developing countries during the recent resource boom. To explore these questions, this...

How rich would resource-abundant countries be if they had actually followed the Hartwick Rule (invest resource rents in other assets) over the past 30 years? The authors use time series data on investments and rents on exhaustible resource extraction for 70 countries to answer this question. The...

The World Bank has been publishing estimates of adjusted net or "genuine" saving since 1999. This measure of saving treats depletion of natural resources as a type of economic depreciation. Hamilton uses recent theoretical results relating growth in saving to growth in future consumption to...

How has environment mattered for the World Bank? The aggregate figures suggest that it has mattered a great deal, since the Bank's total environmental lending has exceeded $US 9 billion over the past six years. In this paper the authors use newly available data to address a more precise version...

New research on urban air pollution casts doubt on the conventional view of the relationship between economic growth and environmental quality. This view holds that pollution automatically increases until societies reach middle-income status because poor countries have neither the institutional...
