This paper examines the effects of restrictions on international financial markets. We analyze a general equilibrium, rational expectations model of a two-country world in which well-functioning international financial markets premit trade in all state-contingent securities except insofar as...

This paper presents a simple model of how a small open economy can undervalue its real exchange rate using its capital account policies. The paper presents several properties of such policies, and proposes a rule of thumb to assess their welfare cost. The model is applied to an analysis of...

We lay down a standard macroeconomic model of a small open economy with a fixed exchange rate and study optimal capital controls (defined as maximizing the utility of a representative household). We provide sharp analytical and numerical characterizations for a variety of shocks. We find that...

The 'International Policy Trilemma' refers to the constraint on independent monetary policy that is forced on a country which remains open to international financial markets and simultaneously pursues an exchange rate target. This paper shows that, in a global economy with open financial...

In a standard two country international macro model we ask whether imposing restrictions on international non-contingent borrowing and lending is ever desirable. The answer is yes. If one country imposes capital controls unilaterally, it can generate favorable changes in the dynamics of...

While new conventional wisdom warns that developing countries should be aware of the risks of premature capital account liberalization, the costs of not removing exchange controls have received much less attention. This paper investigates the negative effects of exchange controls on trade. To...

In this paper I analyze whether restrictions to capital mobility reduce vulnerability to external shocks. More specifically, I ask if countries that restrict the free flow of international capital have a lower probability of experiencing a large contraction in net capital flows. I use three new...

This paper studies the effects of prohibiting individuals from holding foreign assets, and of allowing firms to trade in foreign assets only up to what is needed to finance export and import activities. Although firms can perform arbitrage between domestic and foreign financial markets, the...
