This finding has raised doubts concerning the relevance of the RBC model as well as the quantitative significance of technology shocks as a source of aggregate fluctuations....

The Great Recession, and the fiscal response to it, has revived interest in the size of fiscal multipliers. Standard business cycle models have difficulties generating multipliers greater than one. And they also fail to produce any significant asymmetry in the size of the multipliers over the...

Financial constraints are often thought as representing a barrier to entry for new firms, thus potentially limiting competition in product markets. We investigate the relationship between finance and product market competition in the context of a general equilibrium, two-sector model. The...

We study the effects of uncertainty on the allocation of resources in the standard, static, general equilibrium, two-sector, two-factor model. The elasticity of substitution in production vs that in consumption plays a key role in determining whether uncertainty attracts or repels resources....
