We examine the effectiveness of capital controls versus macroprudential regulation in reducing financial fragility in a small open economy model in which there is excessive borrowing because of externalities associated with financial crises and contractionary exchange rate depreciations. We find...

A salient characteristic of sovereign defaults is that they are typically accompanied by large devaluations. This paper presents new evidence of this empirical regularity known as the Twin Ds and proposes a model that rationalizes it as an optimal policy outcome. The model combines limited...

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...

This paper studies optimal capital-control and bank-reserve remuneration policy in an open economy with a banking channel and a collateral constraint that limits household debt by a fraction of income. It finds that the unregulated economy borrows too little relative to what is optimal...

This paper develops a dynamic model of mismatch. Workers and jobs are randomly assigned to labor markets. Each labor market clears at each instant but some labor markets have more workers than jobs, hence unemployment, and some have more jobs than workers, hence vacancies. As workers and jobs...

Standard neoclassical growth models rarely admits international factor mobility: convergence may result from factor accumulation in a closed economy, or from technology transfer. Conventional models are thus poorly equipped to explain the contribution of international factor flows to convergence...

While technologies and policy fundamentals are presumably different internationally, inducing differences in growth rates, capital mobility is shown to be a powerful force in achieving complete growth rate equalization across countries. We provide evidence in support of this effect, showing that...

This paper analyzes the effectiveness of capital controls, in particular the Chilean experience with the use of the unremunerated reserve requirement. We examine the effects on interest rates, real exchange rate, and the volume and composition of capital inflows. The effects are elusive and it...

The purpose of this paper is to explain the reluctance of developing countries to open up their capital market to foreigners, and the conditions inducing an emerging market economy to switch its policies. We consider an economy characterized initially by a one-sided openness to the capital...
