Does macroeconomic volatility/uncertainty affect accumulation of net foreign assets? In OECD economies over the period 1970-2012, changes in country specific aggregate volatility are, after controlling for a wide array of factors, significantly positively associated with net foreign asset...

We study fiscal and monetary policy in a monetary union with the potential for rollover crises in sovereign debt markets. Member-country fiscal authorities lack commitment to repay their debt and choose fiscal policy independently. A common monetary authority chooses inflation for the union,...

We provide an introduction to optimal fiscal and monetary policy using the primal approach to optimal taxation. We use this approach to address how fiscal and monetary policy should be set over the long run and over the business cycle. We find four substantive lessons for policymaking: Capital...

This paper develops the quantitative implications of optimal fiscal policy in a business cycle model. In a stationary equilibrium the ex ante tax rate on capital income is approximately zero. There is an equivalence class of ex post capital income tax rates and bond policies that support a given...

We examine the limiting behavior of cooperative and noncooperative fiscal policies as countries’ market power goes to zero. We show that these policies converge if countries raise revenues through lump-sum taxation. However, if there are unremovable domestic distortions, such as distorting...

We analyze a real business cycle model in which the government optimally chooses public investment and nonmilitary current expenditures, to maximize the welfare of the representative private agent. We characterize the optimal response of endogenous spending to shocks to technology and to...

This paper develops a two-sector neoclassical model of international trade with endogenous capital accumulation and intertemporal optimization. In contrast to the traditional “2x2x2” model, there is a Ricardian implication that countries specialize according to comparative advantage....

In this paper we use the common perspective provided by the neoclassical growth model to evaluate the size of the distortions associated with different monetary and fiscal policies designed to finance a given sequence of government expenditures. We construct an artificial monetary economy...

A two-country Real Business Cycle (RBC) model is used to study the behavior of the United States trade balance. In this model, economic fluctuations are driven by productivity shocks and by variations in government purchases and in distorting taxes. The model is simulated using quarterly data on...

Inspired by the current European developments, we study equilibrium fiscal policy under alternative constitutional arrangements in a “federation” of countries. There are two levels of government: local and federal. Local policy redistributes across individuals and affects the probability of...
