We study the optimal design of corporate tax policy in a textbook life-cycle model featuring two key deviations: (i) firms are imperfectly competitive and (ii) households save by purchasing equity shares in a stock market. In this simple environment, the financial wealth of savers is equal to...

This paper considers growth and fluctuations in a standard Overlapping Generations (OLG) model with rational expectations, with land (a non-produced asset), credit frictions, and endogenous growth. Under plausible conditions, there can be multiple momentary equilibria, with the multiplicity...

This paper examines the simplest OLG models with capital accumulation, demonstrating three results that stand in marked contrast to those of the standard model: first, the possibility of multiple steady states; second, the possibility of multiple momentary equilibria under rational expectations;...

This paper analyses the impact of credit expansions arising from increases in collateral values or lower interest rate policies on long-run productivity and economic growth in a two-sector endogenous growth economy with credit frictions, with the driver of growth lying in one sector...

This paper analyzes optimal and equilibrium insurance contracts under adverse selection and moral hazard, comparing them with those under a single informational asymmetry. The complex interactions of self-selection and moral hazard constraints have important consequences. We develop an analytic...

In an earlier paper, we showed that integrated individual accounts, allowing individuals to borrow against future pensions when they are unemployed, can be welfare increasing, because it allows increased inter-temporal consumption smoothing without attenuating incentives to search. Here, we...

This paper attempts to provide a more complete reckoning of the costs of the Iraq War, using standard economic and accounting/ budgetary frameworks. As of December 30, 2005, total spending for combat and support operations in Iraq is $251bn, and the CBO's estimates put the projected total direct...

This paper examines alternative hypotheses concerning the determinants of success in the transition from Communism to the market. In particular, we look at whether speed of privatization, legal institutions or initial conditions are more important in explaining the growth of the transition...

This paper analyzes a social insurance system that integrates unemployment insurance with a pension program through an individual account, allowing workers to borrow against their future wage income to finance consumption during an unemployment episode and thus improving their search incentives...

The central objective of this paper is to show how vertical restraints, which affect intra-brand competition, can and will be used as an effective mechanism for reducing inter-brand competition and increasing producer profits. We show how exclusive territories alter the perceived demand curve,...
