We study the welfare implications of uncertainty in business cycle models. In the modern business cycle literature, multiplicative real shocks to production and/or preferences play an important role as the impulses that produce aggregate fluctuations. Introducing shocks in this way has the...

This paper introduces Heckscher-Ohlin trade features into a two-country dynamic stochastic general equilibrium model, and studies the international transmission of productivity shocks through trade in goods. This framework improves upon existing international real business cycle models in that...

If entitlement to UI benefits must be earned with employment, generous UI is an additional benefit to working, so, by itself, it promotes job creation. If individuals are risk neutral, then there is a UI contribution scheme that eliminates any effect of UI on employment decisions. As with...

This paper extends the Markov-switching vector autoregressive models to accommodate both the typical lack of synchronicity that characterizes the real-time daily flow of macroeconomic information and economic indicators sampled at different frequencies. The results of the empirical application...

Previous work of monetary dynamic stochastic general equilibrium models with nominal rigidity a la Taylor, particularly the Cho-Cooley model, was abandoned in favor of the New-Keynesian analysis due to the model's failure to deliver business cycle statistics that match the U.S. economy along...

This paper presents a DGE model in which aggregate price level inertia is generated endogenously by the optimizing behaviour of price-setting firms. All the usual sources of inertia are absent here ie., all firms are simultaneously free to change their price once every period and face no...

We build upon recent research that attributes the moderation of output volatility since the 1980s to the reduced volatility of the Total Factor Productivity (TFP) by investigating the linkage between energy price fluctuations and the stochastic process for TFP. First, we estimate a joint...

In a sticky-price model with labor market search and habit persistence, Walsh (2005) shows that inertia in the interest rate policy helps to reconcile the inflation and output persistence with empirical observations for the US economy. We show that this finding is sensitive with regard to the...

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...
