Galí's innovative approach of imposing long-run restrictions on a vector autoregression (VAR) to identify the effects of a technology shock has become widely utilized. In this paper, we inves-tigate its reliability through Monte Carlo simulations using calibrated business cycle models. Overall,...

In this paper, we use a dynamic stochastic general equilibrium model to examine the effects of an expansion in government spending in a liquidity trap. If the liquidity trap is very prolonged, the spending multiplier can be much larger than in normal circumstances, and the budgetary costs...

In this paper we use a Dynamic Stochastic General Equilibrium (DSGE) model for an open economy to examine the role of sticky prices in explaining the joint behaviour of inflation and a fairly large set of macroeconomic variables. We find that price stickiness is an important feature for firms...
