Standard models of fiscal federalism suggest many benefits of decentralization in developing economies, and there has been a recent push toward decentralization around the world. However, developing countries presently still have less decentralization, particularly on the revenue side, than both...

This paper develops a dynamic, life-cycle, general equilibrium model to study the interdependent demographic, fiscal, and economic transition paths of China, Japan, the U.S., and the EU. Each of these countries/regions is entering a period of rapid and significant aging requiring major fiscal...

One of the most important behavioral parameters in macroeconomics is the elasticity of intertemporal substitution (EIS). Starting with the seminal work of Hall (1978), researchers have used an Euler equation framework to estimate the EIS, relating the growth rate of consumption to the after-tax...

For U.S. annual data that include WWII, the estimated multiplier for temporary defense spending is 0.4-0.5 contemporaneously and 0.6-0.7 over two years. If the change in defense spending is "permanent" (gauged by Ramey's defense-news variable), the multipliers are higher by 0.1-0.2. The...

Many households devote a large fraction of their budgets to "consumption commitments" -- goods that involve transaction costs and are infrequently adjusted. This paper characterizes risk preferences in an expected utility model with commitments. We show that commitments affect risk preferences...

This paper studies Pareto-optimal risk-sharing arrangements in a private information economy with aggregate uncertainty and ex ante heterogeneous agents. I show how to implement Pareto-optima as equilibria when agents can trade claims to consumption contingent on aggregate shocks in financial...

We seek to understand how Laffer curves differ across countries in the US and the EU-14, thereby providing insights into fiscal limits for government spending and the service of sovereign debt. As an application, we analyze the consequences for the permanent sustainability of current debt...

In this paper, we use household-level data from the Panel Study of Income Dynamics to examine the impact of new saving incentives that were implemented as part of the overhaul of U.S. welfare policy during the mid-1990s on the saving of households at risk of entering welfare. The Temporary...

I study the allocation of human capital in an economy with production externalities, financial constraints and career choices. Agents choose to become entrepreneurs, workers or financiers. Entrepreneurship has positive externalities, but innovators face borrowing constraints and require the...

Most economies experience episodes of persistent real exchange rate appreciations, when the question arises whether there is a need for intervention to protect the export sector. In this paper we present a model of irreversible destruction where exchange rate intervention may be justified if the...
