A model of the Twin Ds: optimal default and devaluation
This paper characterizes jointly optimal default and exchange-rate policy in a small open economy with limited enforcement of debt contracts and downward nominal wage rigidity. Under optimal policy, default occurs during contractions and is accompanied by large devaluations. The latter inflate away real wages, thereby avoiding massive unemployment. Thus, the Twin Ds phenomenon emerges endogenously as the optimal outcome. In contrast, under fixed exchange rates, optimal default takes place in the context of large involuntary unemployment. Fixed-exchange-rate economies are shown to have ...

Optimal Foreign Reserve Intervention and Financial Development
We document evidence of a U-shaped relationship between financial development and the adjustments of foreign exchange (FX) reserve holdings in response to a U.S. interest rate increase. Countries with intermediate levels of financial development sell reserves aggressively, while those with low or high levels adjust little. A model with borrowing constraints and foreign-currency debt rationalizes these findings. Optimal FX reserve policy faces a tradeoff between the rate of return on capital outflows and a pecuniary externality linked to foreign currency debt in the borrowing constraints. This ...

Optimal Foreign Reserve Intervention and Financial Development
We document evidence of a U-shaped relationship between financial development and the adjustments of foreign exchange (FX) reserve holdings in response to a U.S. interest rate increase. Countries with intermediate levels of financial development sell reserves aggressively, while those with low or high development adjust little. Domestic interest rate responses are not systematically related to financial development. A model with borrowing constraints and foreign-currency debt rationalizes these findings: the associated pecuniary externality is maximized at intermediate levels of financial ...

Optimal Capital Account Liberalization in China
China maintains tight controls over its capital account. Its current policy regime also features financial repression, under which banks are required to extend funds to state-owned enterprises (SOEs) at favorable terms, despite their lower productivity than private firms on average. We incorporate these features into a general equilibrium model. Our model illustrates a tradeoff between aggregate productivity and inter-temporal allocative efficiency from capital account liberalization under financial repression. As a result, along a transition path with a declining SOE share, ...

Capital Controls and Income Inequality
We examine the distributional implications of capital account policy in a small open economy model with heterogeneous agents and financial frictions. Households save through deposits in both domestic and foreign banks. Entrepreneurs finance investment with borrowed funds from domestic banks and foreign investors. Domestic banks engage in costly intermediation of deposits from households and loans to entrepreneurs. Government capital account policy consists of taxes on outflows and inflows. Given policy, a temporary decline in the world interest rate leads to a surge in inflows, benefiting ...

The Effect of the China Connect
We document the effect on Chinese firms of the Shanghai (Shenzhen)-Hong Kong Stock Connect. The Connect was an important capital account liberalization introduced in the mid-2010s. It created a channel for cross-border equity investments into a selected set of Chinese stocks while China's overall capital controls policy remained in place. Using a difference-in-difference approach, and with careful attention to sample selection issues, we find that mainland Chinese firm-level investment is negatively affected by contractionary U.S. monetary policy shocks and that firms in the Connect are more ...

Capital Controls and the Global Financial Cycle
Capital flows into emerging markets are volatile and associated with risks. A common prescription is to impose counter-cyclical capital controls that tighten during economic booms to mitigate future sudden-stop dynamics, but it has been challenging to document such patterns in the data. Instead, we show that emerging markets tighten their capital controls in response to volatility in international financial markets and elevated risk aversion. We develop a model in which this behavior arises from a desire to manipulate the risk premium. When investors are more risk-averse or markets are ...

Spillovers at the Extremes: The Macroprudential Stance and Vulnerability to the Global Financial Cycle
Evidence suggests that macroprudential policy has small and insignificant effects on the volume of portfolio flows. We show, however, that these minor effects mask very different relationships across the global financial cycle. A tighter ex-ante macroprudential stance amplifies the impact of global risk shocks on bond and equity flows—increasing outflows by significantly more during risk-off episodes and increasing inflows significantly more during risk on episodes. These amplification effects are more prominent at the “extremes,” especially for extreme risk-off periods, and are larger ...

Measuring Capital Controls: Data, Methods, and Trade-offs across De Jure and De Facto Measures
From the tightly managed capital accounts of the Bretton Woods era to today's globally integrated financial markets, capital controls have fundamentally shaped the world economy. Yet, measuring these restrictions accurately remains a challenge for economic researchers. This article provides a comprehensive review of the major approaches to measuring capital controls that exist in the literature. These approaches can be categorized into two types: de jure measures, which capture legal restrictions as written in official policy documents, and de facto measures, which quantify the actual ...
