The textbook neoclassical growth model predicts that countries with faster productivity growth should invest more and attract more foreign capital. We show that the allocation of capital flows across developing countries is the opposite of this prediction: capital does not flow more to countries...

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...

Has the US dollar delivered the benefit that the rest of the world is expecting from its holdings of international liquidity? US government debt has been liquid and safe, and it is supplied in sufficient quantity. But it has given a low return to the countries that accumulated the most reserves,...

We model the motives for residents of a country to hold foreign assets, including the precautionary motive that has been omitted from much previous literature as intractable. Our model captures many of the principal insights from the existing specialized literature on the precautionary motive,...

This paper shows that the scope for bond yields to fall below zero is strictly limited by market expectations about how far below zero central banks are willing to set their short-term policy rates. If a central bank communicates a credible commitment to keeping its policy rate above a given...

In theory, tariffs are partially offset by a currency appreciation in the tariff imposing country or by a depreciation in the country on which the tariff is imposed. Based on a calibrated model, this paper finds that US tariffs imposed in 2018 should not have had a large impact on the dollar but...

We study a dynamic model in which the interaction between debt accumulation and asset prices magnifies credit booms and busts. We find that borrowers do not internalize these feedback effects and therefore suffer from excessively large booms and busts in both credit flows and asset prices. We...

This paper analyzes prudential controls on capital flows to emerging markets from the perspective of a Pigouvian tax that addresses externalities associated with the deleveraging cycle. It presents a model in which restricting capital inflows during boom times reduces the potential outflows...
