|Optimal Reserves in Financially Closed Economies|
with : w22139
Financially closed economies insure themselves against current-account shocks using international reserves. We characterize the optimal management of reserves using an open-economy model of precautionary savings and emphasize several results. First, the welfare-based opportunity cost of reserves differs from the measures often used by practitioners. Second, under plausible calibrations the model is consistent with the rule of thumb that reserves should be close to three months of imports. Third, simple linear rules can capture most of the welfare gains from optimal reserve management. Fourth, policymakers should place more emphasis on how to use reserves in response to shocks than on the reserve target itself.

|December 2014||Capital Controls or Macroprudential Regulation?|
with : w20805
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 that both types of instruments play distinct roles: macroprudential regulation reduces the indebtedness of leveraged borrowers whereas capital controls induce more precautionary behavior for the economy as a whole, including for savers. This reduces crisis risk by shoring up aggregate net worth and mitigating the transfer problem that occurs during crises. In advanced countries where the risk of large contractionary depreciations is more limited, the role for capital controls subsides. However, mac...

|October 2009||Macro-Hedging for Commodity Exporters|
with , : w15452
This paper uses a dynamic optimization model to estimate the welfare gains of hedging against commodity price risk for commodity-exporting countries. We show that the introduction of hedging instruments such as futures and options enhances domestic welfare through two channels. First, by reducing export income volatility and allowing for a smoother consumption path. Second, by reducing the country's need to hold foreign assets as precautionary savings (or by improving the country's ability to borrow against future export income). Under plausibly calibrated parameters, the second channel may lead to much larger welfare gains, amounting to several percentage points of annual consumption.
