A conservation good, such as the rainforest, is a hostage: it is possessed by S who may prefer to consume it, but B receives a larger value from continued conservation. A range of prices would make trade mutually beneficial. So, why doesn't B purchase conservation, or the forest, from S?

This paper discusses the recent research on the consumption function that has attempted to relax the assumption of certainty equivalence. While there remain many open questions, both theoretical and empirical, it is clear that the assumption of certainty equivalence can be misleading. Under more...

Mankiw [1982] explores the Permanent Income Hypothesis implication that durable expenditures follow an ARMA(1,1) representation. He finds that durable expenditures are represented by an AR(1) process which implies that the rate of depreciation of durables, under the PIH model, is 100%. This...

A standard model of addictive process is Becker and Murphy's rational addiction' model, which has the key empirical prediction that the current consumption of addictive goods should respond to future prices, and the key normative prediction that the optimal government regulation of addictive...

Theory predicts that in markets with increasing returns, the number of differentiated products and resulting consumer satisfaction grow in market size. We document this phenomenon across 246 US radio markets. By a mechanism that we term 'preference externalities', an increase in the size of the...

This paper extends my research applying statistical decision theory to treatment choice with sample data, using maximum regret to evaluate the performance of treatment rules. The specific new contribution is to study as-if optimization using estimates of illness probabilities in clinical choice...
