Over the past 15 years there has been remarkable progress in the specification and estimation of dynamic stochastic general equilibrium (DSGE) models. Central banks in developed and emerging market economies have become increasingly interested in their usefulness for policy analysis and...

We examine the effect of uncertainty arising from policy-shock volatility on yield-curve dynamics. In contrast to the assumption of many macro-finance models, policy-shock processes appear to be time varying and persistent. We allow for this heteroskedasticity by constructing a no-arbitrage...

The paper discusses the latest economic crisis and the public policies used to mitigate the recession and improve the economic growth. The current target rate (monetary policy) is closed to zero since December 2008 with a new experimental policy (“quantitative easing”) to stimulate...

This paper offers a reappraisal of the inflation-unemployment tradeoff, based on "frictional growth" describing the interplay between nominal frictions and money growth. When the money supply grows in the presence of price inertia (due to staggered wage contracts with time discounting), the...

It is widely believed that the Fed controls the funds rate by altering the degree of pressure in the reserve market through open market operations when it changes its target for the federal funds rate. Recently, however, several economists have suggested that open market operations may not be...

This paper takes a new look at the long-run dynamics of inflation and unemployment in response to permanent changes in the growth rate of the money supply. We examine the Phillips curve from the perspective of what we call "frictional growth," i.e. the interaction between money growth and...

Recent studies on the growth effects of exchange rate regimes offer a wide range of different, sometimes contradictory results. In this paper, we systematically compare three prominent contributions in this field. Using a common data set, a common specification, and common estimation methods, we...
