This paper uses a dynamic general equilibrium model to analyze and quantify the aggregate effects of the timing of tax rate changes enacted in 2001 (which called for successive rate reductions through 2006) and 2003 (which made immediate tax rate cuts scheduled for 2004 and 2006). The phased-in...

The intertemporal elasticity of investment for long-lived capital goods is nearly infinite. Consequently, investment prices should fully reflect temporary tax subsidies, regardless of the investment supply elasticity. Since prices move one-for-one with the subsidy, elasticities can be inferred...

The inclusion of a durable goods sector in sticky-price models has strong and unexpected implications. Even if most prices are flexible, a small durable goods sector with sticky prices may be sufficient to make aggregate output react to monetary policy as though most prices were sticky. In...

We estimate a state-of-the-art DSGE model to study the natural rate of interest in the United States over the last 20 years. The natural rate is highly procyclical, and fell substantially below zero in each of the last three recessions. Although the drop was of comparable magnitude across the...
