We characterize a planner's optimal allocation of consumption and capital in an overlapping generations model with exogenous government purchases, privately-observed idiosyncratic shocks to the depreciation rate of capital, and a proportional cost of reversing investment to transform used...

To help first- or second-year graduate students in economics apply their theoretical training, this paper shows how to solve a simple and intuitive computable general equilibrium (CGE) model using a calculator. Because this simplified Harberger model uses Cobb Douglas functional forms for...

Monetary theory and policy are part of intertemporal public finance. The lecture reviews some interesting recent developments. The two ghosts are the venerable liquidity trap and the Pigou effect or real balance effect. The eccentricities are negative nominal interest rates and the helicopter...

Financial reports present assets, liabilities, and earnings on a nominal basis (unadjusted for inflation). Using a novel dataset of nearly a century of financial reports, this paper examines whether and how inflation affects the relation between accounting earnings and stock market value, i.e.,...

Local governments spend roughly $1.6 trillion per year to provide a variety of public services ranging from police and fire protection to public schools and public transit. However, we know little about public sector's productivity in delivering key services. To understand the productivity both...

America's local governments spend about one-eighth of our national income, one-fourth of total government spending, and employ over 14 million people. This paper surveys the large and growing economics literature on local governments and their finances. A primary difference between local and...

This paper uses historical census data from Burkina Faso to characterize local demographic pressures associated with internal migration into river valleys after Onchocerciasis eradication, combined with a new survey of village elders to document change over time and differences across villages...

This paper revisits the classic argument that a system of local governments financing public service provision via property taxes will produce an efficient allocation of both housing and services if communities can implement zoning ordinances. The novel feature of the analysis is a dynamic model...

Governments often contract with private firms to provide public services such as health care and education. To decrease firms' incentives to selectively enroll low-cost individuals, governments frequently "risk-adjust" payments to firms based on enrollees' characteristics. We model how risk...

We develop and test an economic theory of insurgency motivated by the informal literature and by recent military doctrine. We model a three-way contest between violent rebels, a government seeking to minimize violence by mixing service provision and coercion, and civilians deciding whether to...
