The view that intergenerational distributive justice and efficiency should be treated separately is familiar, yet controversial. This article elaborates the often-implicit justifications for separate treatment and provides a more express statement of how and when such treatment is appropriate....

Economic theory predicts that individual recycling behavior gravitates toward extremes--either diligent recycling or no recycling at all. Using a nationally representative sample of 3,158 bottled water users, this article finds that this prediction is borne out for consumer recycling of plastic...

Governments are facing an increasing number of arbitration claims by foreign investors relating to important public policies or seeking substantial damages, and many governments are taking a greater joint interest in how such cases are resolved in investor-state dispute settlement (ISDS). This...

We extend the Arrow-Fisher-Hanemann-Henry (AFHH) and Dixit-Pindyck (DP) option values to a game situation. By reinterpreting the AFHH option value as a change in the surplus from conservation because of the prospect of future information, we deal with a conceptual difficulty associated with the...

We consider a simple two-period model of irreversible investment under strategic interactions between two players. In this setup, we show that the quasi-option value may cause some conceptual difficulties. In case of asymmetric information, decentralized investment decisions fail to induce...

How much does the environment affect human health? Is air pollution shortening our lives and those of our children? These questions are fundamental to environmental policies. Air pollution is a major environmental health threat in OECD countries, contributing to a number of illnesses, such as...

The choice of the rate at which one should discount the long-term benefits of mitigating climate change is highly controversial. Both the level and the slope of the term structure of discount rates have been discussed intensively in relation to the determination of the social cost of carbon....

Optimal policy rules--including those regarding income taxation, commodity taxation, public goods, and externalities--are typically derived in models with homogeneous preferences. This article reconsiders many central results for the case in which preferences for commodities, public goods, and...

For two independent principles of intergenerational equity, the implied discount rate equals the growth rate of real per capita income, say, 2%, thus falling right into the range suggested by the U.S. Office of Management and Budget. To prove this, we develop a simple tool to evaluate small...
