Annie Soyean Lee

I am an Assistant Professor of International Economics at Johns Hopkins University, SAIS. I received my Ph.D. in Economics from the University of Wisconsin-Madison in May 2022.

My research interest lies in the determinants of the currency composition of assets and liabilities of governments, private agents, and the aggregate economy. I specifically focus on the role of exchange rate risk in currency choice, and the macroeconomic implications of such choices.

I am co-organizing Johns Hopkins University SAIS-KSAS-Carey Geoeconomics Conference on May 2-3, 2025.

Carry Trades and FX Risk Buffers: Foreign Currency Debt of Emerging Market Firms (with Steve Pak Yeung Wu)

Accepted at Review of Economics and Statistics

[publisher link] [working paper version] [online appendix]

Abstract: The surge in foreign currency (FC) corporate debt in emerging economies has sparked concerns about macroeconomic stability, heightened by speculation about non-financial firms engaging in carry trades. Using firm-level data on the currency denomination of both assets and liabilities, we find evidence of firms’ carry trades: firms save in local currency liquid assets and earn higher interest income after issuing short-term FC debt. They also set aside FC liquid assets as FX risk buffers. A large degree of heterogeneity in incentives is observed. Notably, listed firms participate more in carry trades and allocate less FX risk buffers than non-listed firms.

Liability Dollarization and Exchange Rate Pass-Through To Domestic Prices (with Junhyong Kim), Revision Requested

[paper] This version: June 2024

Abstract: We explore the negative balance sheet effect of foreign currency borrowing on the exchange rate pass-through to domestic prices. Exploiting a large unexpected devaluation episode in Korea in 1997, we show that firms with higher foreign currency debt have indeed experienced balance sheet deterioration and faced lower growth rates of sales and net worths and reduced their price-cost markups. We then empirically document that a sector populated by firms with higher foreign currency debt exposure prior to the crisis experienced a larger price increase. Building a heterogeneous firm model with financial constraints, we quantify the role of foreign currency liabilities in explaining the exchange rate pass-through to prices and find that 20% to 80% of the sectoral price changes during the crisis can be explained by the balance sheet effect of foreign currency debt alone. We emphasize the role of strategic complementarity in amplifying the sectoral price increase.

U.S. Liquid Government Liabilities and Emerging Market Capital Flows (with Charles Engel)

[paper] [NBER WP] This version: March 2025

Abstract: Empirical work finds that flows of investments from the U.S. and other high income countries to emerging markets increase during times of quantitative easing (QE) by the U.S. Federal Reserve, and the reverse movement occurs under quantitative tightening. We offer new evidence to confirm these findings, and then propose a theory based on the liquidity of U.S. government liabilities held by the public. We hypothesize that QE, by increasing liquidity, offers greater flexibility for investors that might be concerned their funds will be tied up when shocks to income or investment opportunities arise. With the assurance that some of their portfolio can be readily sold in liquid markets, rich country investors are more willing to increase investments in illiquid loans to emerging markets. The effect of increasing the liquidity of U.S. government liabilities on investments in EMs may even be stronger during times of greater uncertainty. We find evidence to support our interpretation: QE lowers covered interest parity deviations for the dollar, as our model predicts.

Corporate Dollar Debt and Global Trades: The Role of Firm Heterogeneity (with Junhyong Kim and Saiah Lee)

[paper] This version: September 2024

Abstract: This paper investigates the role of dollar debt and firm heterogeneity in shaping the exchange rate pass-through to global trades. We employ a unique dataset that combines detailed firm-level balance sheet information with transaction-level Korean customs data. Our findings reveal that after the 1997 devaluation, small exporters with higher levels of foreign currency debt tend to reduce their export quantities and raise their prices. In contrast, for large exporters, higher foreign currency debt results in higher export quantities and lower prices. The heterogeneous price and quantity responses across firm size may stem from financial frictions that smaller firms face, unlike large firms. Small firms burdened by foreign currency debt face tighter financial constraints, which limit their production. Large firms, however, may experience less disruption in their production even when highly exposed to foreign currency debt. Consequently, they could increase their exports to generate more cashflows, even if it means sacrificing future cash flows, particularly when they require liquidity due to high levels of foreign currency debt. The panel data analysis from 2001-2020 confirms the relevance of the financial channel of dollar debt in the exchange rate pass-through to export prices and quantities in more recent periods.

Why Do Emerging Economies Borrow in Foreign Currency? The Role of Exchange Rate Risk

[paper] [slides] This version: October 2024

Abstract: Borrowing in foreign currency often leads to currency mismatches on emerging economies’ balance sheets, causing financial instability. Nonetheless, emerging market governments borrow more in foreign currency, particularly when exchange rate volatility is higher. This paper develops a sovereign default model with risk-averse international lenders, where emerging economies bear the exchange rate risk due to the high foreign exchange risk premium on local currency debt. The model effectively captures the cost of borrowing in local and foreign currency and the currency composition of external public debt, suggesting a 0.35% welfare gain from exchange rate stabilization for emerging market sovereigns.

Implications of Infrequent Portfolio Adjustment for International Portfolio Choices

[paper] This version: April 2022

Abstract: This paper helps unravel the long-standing equity home bias puzzle by building a model in which an agent infrequently adjusts her portfolio holdings of home and foreign equities. As real exchange rate returns are volatile, an investor who invests in foreign equities and holds on to her portfolio holdings for a long duration is likely to drift away from an optimal allocation. The agent, taking infrequent adjustment into account ex-ante, lowers her demand for foreign equities, generating home bias in equities. The introduction of the euro into various European countries and the enlargement of euro area in subsequent years provide a natural environment in which to validate the implications of the model. We empirically document that European countries experience lower equity home bias after adopting the euro as cross-border equity investment within the euro area entails no nominal exchange rate risk. When the levels of real exchange rate volatility are calibrated to match the average levels for European countries in the euro area and outside the euro area, the model can match the difference in levels of equity home bias between European countries experienced after the introduction of the euro.
