We investigate optimal consumption, asset accumulation and portfolio decisions in a realistically calibrated life-cycle model with flexible labor supply. Our framework allows for wage rate uncertainly, variable labor supply, social security benefits and portfolio choice over safe bonds and risky...

Fiscal policy in the U.S. and other countries renders intertemporal budgets non-differentiable, nonconvex, and discontinuous. Consequently, assessing work and saving responses to policy requires global optimization. This paper develops the Global Life-Cycle Optimizer (GLO), a stochastic...

Policy rules that are consistent with inflation targeting are examined in a small macroeconomic model of the US economy. We compare the properties and outcomes of explicit instrument rules' as well as targeting rules.' The latter, which imply implicit instrument rules, may be closer to actual...

Recent changes in patterns of international trade and growth have rekindled interest in the relationships among trade, growth, and the international distribution of income. Three alternative models can serve as a theoretical foundation for an empirical analysis of these relationships. The first...

This paper develops a general equilibrium two country, two commodity dynamic simulation model of international trade in commodities and financial claims. The model generalizes the Heckscher-Ohlin static theory of trade by incorporating costs of quickly adjusting levels of capital stocks in...

China eventually becomes the world's saver and, thereby, the developed world's savoir with respect to its long-run supply of capital and long-run general equilibrium prospects. And, rather than seeing the real wage per unit of human capital fall, the West and Japan see it rise by one fifth by...

We simulate corporate tax reform in a single good, five-region (U.S., Europe, Japan, China, India) model, featuring skilled and unskilled labor, detailed region-specific demographics and fiscal policies. Eliminating the model's U.S. corporate income tax produces rapid and dramatic increases in...

The paper extends previous analysis of closed-economy inflation targeting to a small open economy with forward-looking aggregate supply and demand with some microfoundations, and with stylized realistic lags in the different transmission channels for monetary policy. The paper compares targeting...

This paper develops, calibrates, and simulates a dynamic 88-period OLG model to study the intergenerational transmission of U.S. wealth inequality via bequests. The model features marriage, realistic fertility patterns, random death, assortative mating based on skills, heterogeneous skill...

This paper presents a new solution to the time-consistency problem that appears capable of enforcing ex ante policy in a variety of settings in which other enforcement mechanisms do not work. The solution involves formulating a law, institution, or agreement that specifies the optimal ex ante...
