The Social Discount Rate
What discount rate should be applied to social investments? It is standard to use the market interest rate, thereby respecting private preferences. We show that application of this “revealed preference” criterion rests on faith, not logic. It is justified only if preferences over all choices, including past choices, are time invariant. The conditions for this to be true are stringent. Under mor...
متن کاملThe Long-Term Discount Rate∗
We develop an expression for the long-term discount rate in an economy in which a representative consumer has access to both a risk-free and a risky production technology. Even when the risk-free sector is very small, and with probability one becomes a negligible fraction of the economy in the long run, interest rates are determined differently than in a single-sector economy. As in a single-ri...
متن کاملThe Consumption Discount Rate for the Distant
Gollier and Weitzman (2010) show that if future consumption discount rates are uncertain and persistent, the consumption discount rate should decline to its lowest possible value for events in the most distant future. In this paper, I argue that the lowest possible growth rate of consumption per capita in the distant future is zero (assuming that humans do not die out). Substituting in the Rams...

The underlying assumptions are that public budgets displace the marginal private investment, and that US citizens borrow to finance home mortgages. The average debt capacity of the US citizen, or the representative investor, is 20%. It is argued that...
متن کاملEnergy Policy and the Social Discount Rate
Recent debates over the economics of climate change underscore the importance of what at first blush is a narrow technical issue in welfare economics and cost-benefit analysis (CBA). Yet even before the need to study the economics of climate change, debate over both nuclear energy policy and water resource policy highlighted the fateful role that social discount rates play in policy prescriptio...
