Global warming is a worldwide and protracted phenomenon with heterogeneous local economic effects. In order to evaluate the aggregate and local economic consequences of higher temperatures, we propose a dynamic economic assessment model of the world economy with high spatial resolution. Our...

We develop a dynamic equilibrium model of labor demand with adverse selection. Firms learn the quality of newly hired workers after a period of employment. Adverse selection makes it costly to hire new workers and to release productive workers. As a result, firms hoard labor and under-react to...

We study the relationship between unemployment, environmental policy, and business cycles. We develop a dynamic stochastic general equilibrium real business cycle model that includes both a pollution externality and congestion externalities from labor market search frictions, which generate...

An important component of the debate surrounding climate legislation in the United States is its potential impact on labor markets. Theoretically the connection is ambiguous and depends on the sign of cross-elasticity of labor demand with respect to energy prices, which is a priori unknown. This...

This paper builds a single model that can be used to show efficiency and distributional effects of eight different types of environmental policies (including taxes, subsidies, regulations, permits, and legal liability). All eight approaches can be designed to have the same efficiency effects,...

This paper analyzes the effects of environmental policy on employment (and unemployment) using a new general-equilibrium two-sector search model. We find that imposing a pollution tax causes substantial reductions in employment in the regulated (polluting) industry, but this is offset by...

Increasingly in U.S. public insurance programs, the state finances and regulates competing, capitated private health plans but does not itself directly insure beneficiaries through a public fee-for-service (FFS) plan. We develop a simple model of risk-selection in such settings. Capitation...

We analyze the interaction between managerial decisions and firm value/asset prices by embedding the standard agency model of the firm into an otherwise standard asset pricing model. When the manager-agent's compensation depends on the firm's stock price performance, stock prices are set to...
