Data for the United States and countries in Western Europe indicate a negative correlation between the dependency ratio and both labor tax rates and the generosity of social transfers, after controlling for other factors that influence the size of the welfare state. This is despite the increased...

We compare the long-term output and current account effects of pension reforms that increase the retirement age with those of reforms that cut pension benefits, conditional on reforms achieving similar fiscal targets. We show the presence of a policy trade-off. Pension reforms that increase the...

Several European countries are currently considering reversing parts of their pension reforms that were adopted previously to improve sustainability. In this paper we present a framework that allows us to quantify the macroeconomic and fiscal costs of such reversals. We thereby integrate the...

As of 2015, U.S. log output per capita was 12 percent below what its pre-2008 linear trend would predict. To understand why, I develop and estimate a model of the US with demographics, real and monetary shocks, and the occasionally binding ZLB on nominal rates. Demographic changes generate...

This paper examines whether there is a case for temporary but persistent fiscal surpluses in economies heavily endowed with nonrenewable resources. It finds that there generally is a case. Fiscal surpluses permit replacing nonfinancial wealth with financial assets, the return on which increases...

This paper simulates the macroeconomic effects of population aging in a dynamic overlapping generations model of a small open economy. The model is calibrated to data for the Czech Republic, where population aging is proceeding at a pace comparable to that in other advanced countries in Europe....

This paper analyzes the dynamic interactions between the precision of information, technological development, and welfare within an overlapping generations model. More precise information about idiosyncratic production shocks has ambiguous effects on technological progress and welfare, which...

This paper examines the link between capital stock and unemployment persistence. An overlapping-generations model with endogenous labor supply and imperfect competition is presented. It is used to interpret the unusual persistence of unemployment in Trinidad and Tobago during the last twenty...

An increasing body of evidence suggests that the behavior of the economy has changed in many fundamental ways over the last decades. In particular, greater financial deregulation, larger wealth accumulation, and better policies might have helped lower uncertainty about future income and lengthen...
