Two heterogeneous agents contribute over time to a joint project, and collectively decide its scope. A larger scope requires greater cumulative effort and delivers higher benefits upon completion. We show that the efficient agent prefers a smaller scope, and preferences are time-inconsistent: as...

I examine Ronald Coase's criticism of standard regulatory and tax policies to address environmental externalities. I elaborate some of Coase's key points and discuss opportunities for Coasean exchange as an alternative mitigation approach. Regulation, tax, and Coasean exchange, such as through...

We develop a conceptual framework to highlight the role of ideas as a catalyst for policy and institutional change. We make an explicit distinction between ideas and vested interests and show how they feed into each other. In doing so the paper integrates the Keynes-Hayek perspective on the...

Observed fiscal policy varies greatly across time and countries. How can we explain this variation across time and countries? This paper surveys the recent literature that has tried to answer this question. We adopt a unified approach in portraying public policy as the equilibrium outcome of an...
