This paper reexamines the question of how to explain business cycle co-movements within and between countries. First, we present a simple flexible price models to illustrate how and why news shocks can generate robust positive co-movements in economic activity across countries. We also discuss...

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...

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...

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...

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...

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 extend the basic RBC model to allow for biased technical changes. One broad definition of biased technical changes is changes that directly affect factor elasticities. Given the link between changes in factor elasticities and factor shares, observed fluctuations in US labor's share are...

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...

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...
