This paper extends the standard Diamond's two-period OLG model of capital accumulation by introducing labor-leisure choice into the first-period of agents' life. Under the assumption of gross substitutability, we show that multiple intertemporal equilibria require both highly complementary...

Empirical evidence suggests that goods are highly heterogeneous with respect to the degree of price rigidity. We develop a two-sector dynamic general equilibrium model to study the equilibrium determinacy properties of interest rate rules that respond to inflation measures differing in their...

We argue that more workers choose to switch occupations in booms than in recessions. That is, skill retooling is procyclical. This view is consistent with Lucas and Prescotts (1974) equilibrium search model modified with aggregate shocks and unemployment insurance. Empirical support is found in...

We construct a dynamic general equilibrium model to assess the quantitative relationship between real interest rates and output fluctuations in the Brazilian economy from 1980 to 2001. When firms are subject to working capital restrictions, the model is consistent with both the cyclical...

This paper estimates and simulates a sticky-price dynamic stochastic general-equilibrium model with a financial accelerator, a la Bernanke, Gertler, and Gilchrist (1999), to assess the importance of the financial accelerator mechanism in fitting the data and its role in the amplification and...

There are substantial differences in business cycle fluctuations across countries. These differences are systematically related to the share of agriculture in the economy: Countries with a high share of employment in agriculture feature high fluctuations in aggregate output, low relative...

This paper examines the impact of sticky price and limited participation frictions, both separately and combined, in a dynamic stochastic general equilibrium model. Using U.S. data on output, inflation, interest rates, money growth, consumption, and investment, likelihood ratio tests and...

Open economy extensions of real business cycle models, even if generally successful, have met some difficulties replicating a few important stylized facts. In particular these models tend to predict excessive consumption smoothing and consumption correlation across countries. The observed...

I study the welfare cost of business cycles in a complete-markets economy where some people are more risk averse than others. Relatively more risk-averse people buy insurance against aggregate risk, and relatively less risk-averse people sell insurance. These trades reduce the welfare cost of...

In a standard overlapping generations model, active monetary policy reinforces mechanisms that lead to equilibrium indeterminacy and to countercyclical behavior of young-age consumption. The policy rule which minimizes inflation volatility can be active or passive, depending on the...
