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, using a six-region DSGE model of the world economy, assesses the GDP and current account implications of permanent oil supply shocks hitting the world economy at an unspecified future date. For modest-sized shocks and conventional production technologies the effects are modest. But...

This paper assesses sustainable fiscal behavior in an economy where wealth is derived predominantly from a non-renewable resource. It explores the issue in a simple dynamic framework that highlights the structural weaknesses in the underlying budgetary position, takes into account the rate of...

Exporters of exhaustible resources have historically exhibited higher income volatility than other economies, suggesting a heightened role for precautionary savings. This paper uses a parameterized small open economy model to quantify the role of precautionary savings in economies with...

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 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....
