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,...

We develop and estimate an open economy New Keynesian Phillips curve (NKPC) in which variable demand elasticities give rise to movements in desired markups in response to changes in competitive pressure from abroad. A parametric restriction on our specification yields the standard NKPC, in which...

We develop and estimate an open economy New Keynesian Phillips Curve (NKPC) in which variable demand elasticities give rise to movements in desired markups in response to changes in competitive pressure from abroad. A parametric restriction yields the standard NKPC under constant elasticity and...

In a stylized DSGE model with an energy sector, the optimal policy response to an adverse energy supply shock implies a rise in core inflation, a larger rise in headline inflation, and a decline in wage inflation. The optimal policy is well approximated by policies that stabilize the output gap,...

We examine the effects of endogenously determined oil price fluctuations in a two-country DSGE model. Under incomplete financial markets, an oil market-specific shock that boosts the oil price results in a wealth transfer toward oil exporters, depresses the oil importer's consumption, and causes...

Using Bayesian methods, we estimate a nonlinear DSGE model in which the interest-rate lower bound is occasionally binding. We quantify the size and nature of disturbances that pushed the U.S. economy to the lower bound in late 2008 as well as the contribution of the lower bound constraint to the...
