The Real Exchange Rate, Innovation and Productivity
Addressing debates on the effects of real exchange rate (RER) movements on the economy, this study examines manufacturing firm-level effects of medium-term fluctuations, in particular firm-level productivity across a wide range of countries. RER changes have different impacts depending on the export and import orientation of regions and the prevalence of credit constraints. Effects are non-linear and asymmetric, suggesting that the link between RER changes and macroeconomic performance might be much more nuanced than usually thought.

Sovereign Risk, Currency Risk, and Corporate Balance Sheets
Why would a country default on its sovereign debt when the government could instead inflate it away? The authors argue that a government is more inclined to default than inflate when the currency mismatch of the corporate sector implies large adverse balance sheet effects from a currency depreciation. To make this argument they construct a dataset on the currency composition of emerging market external borrowing. Results show that the corporate sector relies on external foreign currency debt even as sovereigns have swiftly moved toward borrowing in their own currency.
