This paper is a chapter in the forthcoming Handbook of International Economics. It surveys the literature on the specification of models of asset markets and the implications of differences in specification for the macroeconomic adjustment process. Builders of portfolio balance models have...

We show that a fiscal expansion by the core economies of the euro area would have a large and positive impact on periphery GDP assuming that policy rates remain low for a prolonged period. Under our preferred model specification, an expansion of core government spending equal to one percent of...

This paper uses an open economy DSGE model to explore how trade openness affects the transmission of domestic shocks. For some calibrations, closed and open economies appear dramatically different, reminiscent of the implications of Mundell-Fleming style models. However, we argue such stark...

This paper examines the ability of a simple stylized general equilibrium model that incorporates nominal wage rigidity to explain the magnitude and persistence of the Great Depression in the United States. The impulses to our analysis are money supply shocks. The Taylor contracts model is...

In the wake of a severe recession and a sluggish recovery, labor market slack cannot be gauged solely in terms of the conventional measure of the unemployment rate (that is, the number of individuals who are not working at all and actively searching for a job). Rather, assessments of the...

We use a micro-founded macroeconometric modeling framework to investigate the design of monetary policy when the central bank faces uncertainty about the true structure of the economy. We apply Bayesian methods to estimate the parameters of the baseline specification using postwar U.S. data, and...

If the global economy encounters another severe adverse shock in coming years, will major central banks be able to provide sufficient monetary stimulus to preserve price stability and foster economic recovery? Our empirical analysis indicates that the Federal Reserve's QE3 program was not an...

We consider how a central bank digital currency (CBDC) could transform all aspects of the monetary system and facilitate the systematic and transparent conduct of monetary policy. In particular, we find that CBDC can serve as a practically costless medium of exchange, secure store of value, and...

Microeconomic evidence indicates a very high frequency of price adjustment in low income countries (LICs), raising the question of whether LICs may be reasonably characterized as exhibiting monetary neutrality. To address this question, we analyze a cross-country panel dataset of 79 LICs over...

To assess age-specific infection fatality rates (IFRs) for COVID-19, we have conducted a systematic review of seroprevalence studies as well as countries with comprehensive tracing programs. Age-specific IFRs were computed using the prevalence data in conjunction with reported fatalities four...
