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 ...

Liquidity traps, capital flows
Motivated by debates surrounding international capital flows during the Great Recession, we conduct a positive and normative analysis of capital flows when a region of the global economy experiences a liquidity trap. Capital flows reduce inefficient output fluctuations in this region by inducing exchange rate movements that reallocate expenditure toward the goods it produces. Restricting capital mobility hampers such an adjustment. From a global perspective, constrained efficiency entails subsidizing capital flows to address an aggregate demand externality associated with exchange rate ...

The Impact of Bretton Woods International Capital Controls on the Global Economy and the Value of Geopolitical Stability: A General Equilibrium Analysis
This paper quantifies the positive and normative effects of Bretton Woods capital controls on global economic activity. It applies a three-region DSGE model of the U.S., Western Europe, and the Rest of the World (ROW) that measures capital controls using observed regional consumption growth differences. We find sizable controls during Bretton Woods that prevented ROW capital from flowing to the U.S., and which reduced U.S. welfare and raised ROW welfare. By preventing capital flight in developing economies, we find that Bretton Woods controls promoted the U.S. foreign policy objective of ...

Optimal Policy for Macro-Financial Stability
There is a new and now large literature analyzing government policies for financial stability based on models with endogenous borrowing constraints. These normative analyses build upon the concept of constrained efficient allocation, where the social planner is constrained by the same borrowing limit that agents face. In this paper, we show that the same set of policy tools that implement the constrained efficient allocation can be used by a Ramsey planner to replicate the unconstrained allocation, thus achieving higher welfare. The constrained social planner approach may lead to inaccurate ...

The Anatomy of Export Controls
Governments increasingly use export controls to limit the spread of domestic cutting-edge technologies to other countries. The sectors that are currently involved in this geopolitical race include semiconductors, telecommunications, and artificial intelligence. Despite their growing adoption, little is known about the effect of export controls on supply chains and the productive sector at large. Do export controls induce a selective decoupling of the targeted goods and sectors? How do global customer-supplier relations react to export controls? What are their effects on the productive sector? ...

The Impact of Bretton Woods International Capital Controls on the Global Economy and the Value of Geopolitical Stability: A General Equilibrium Analysis
This paper quantifies the positive and normative impacts of Bretton Woods capital controls on global and regional economic activity. A three-region DSGE capital flows accounting framework consisting of the U.S., Western Europe, and the Rest of the World (ROW) is developed to quantify capital controls and evaluate their impact on the world economy. We conduct counterfactual analyses that eliminate Bretton Woods’ capital controls and find these controls substantially reduced global capital flows, had large negative welfare effects on the U.S., raised welfare substantially in the ROW, and ...

Securing Technological Leadership? The Cost of Export Controls on Firms
To safeguard its technological leadership, the U.S. has restricted domestic suppliers from exporting specific cutting-edge technologies to selected Chinese firms. Domestic firms affected by these export controls halt sales to Chinese customers, as intended, but struggle to establish new relations with alternative customers domestically or in politically aligned regions. As a result, domestic suppliers experience a $130 billion decline in market capitalization, along with reductions in profitability, employment, and bank lending. We also show how Chinese firms strategically respond to export ...

The Consequences of Bretton Woods’ International Capital Controls and the High Value of Geopolitical Stability
This paper quantifies the positive and normative effects of international capital controls on global and regional economic activity under The Bretton Woods international financial system and thereafter. A three region, open economy, DSGE capital flows accounting framework consisting of the U.S., Western Europe, and the Rest of the World, is developed to identify capital controls and quantify their impact. We find these controls had large positive and normative effects by restricting international capital flows. Counterfactual analyses show world output would have been 0.6% higher had there ...

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 ...

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 ...
