Many social outcomes are reached by means of competitions between opposing actors. While the positive effects of competition are beyond dispute, this paper contends that competitive situations also trigger a particular psychological mindset that can distort contestants’ judgment and lead to...

An Equivalence Theorem between geometric structures and utility functions allows new methods for understanding preferences. Our classification of valuations into “Demand Types” incorporates existing definitions (substitutes, complements, “strong substitutes,” etc.) and permits new ones....

We investigate how irreversibility in “dirty” and “clean” capital stocks affects optimal climate policy, from both theoretical and numerical perspectives. An increasing carbon tax will reduce investments in assets that pollute, and so reduce emissions in the short term: our...
