We develop a theory of capital controls as dynamic terms-of-trade manipulation. We study an infinite-horizon endowment economy with two countries. One country chooses taxes on international capital flows in order to maximize the welfare of its representative agent, while the other country is...

This paper develops a simple theory of capital controls as dynamic terms-of-trade manipulation. We study an infinite horizon endowment economy with two countries. One country chooses taxes on international capital flows in order to maximize the welfare of its representative agent, while the...

The theory of comparative advantage is at the core of neoclassical trade theory. Yet we know little about its implications for how nations should conduct their trade policy. For example, should import sectors with weaker comparative advantage be protected more? Conversely, should export sectors...

What circumstances or policies leave sovereign borrowers at the mercy of self-fulfilling increases in interest rates? To answer this question, we study the dynamics of debt and interest rates in a model where default is driven by insolvency. Fiscal deficits and surpluses are subject to shocks...

We explore steady-state inequality in an intergenerational model with altruistically linked individuals who experience privately observed taste shocks. When the welfare function depends only on the initial generation, efficiency requires immiseration: inequality grows without bound and...

Abstract We provide a unifying foundation for monetary policy and macroprudential policies in financial markets for economies with nominal rigidities in goods and labor markets and constraints on monetary policy such as the zero lower bound or fixed exchange rates. Macroprudential interventions...

This paper builds a continuous time model of government saving behavior. The model features rulers that rotate out of power. The ruler makes two decisions: a. total spending expenditure; and b. the composition of spending between two goods, one with public benefits and another with private...
