International Trade of Essential Goods During a Pandemic
This paper studies the role of international trade of essential goods during a pandemic. We consider a multi-country, multi-sector model with essential and non-essential goods. Essential goods provide utility relative to a reference consumption level, and a pandemic consists of an increase in this reference level. Each country produces domestic varieties of both types of goods using capital and labor subject to sectoral adjustment costs, and all varieties are traded internationally subject to trade barriers. We study the role of international trade of essential goods in mitigating or ...

Financial Development and International Trade
This paper studies the industry-level and aggregate implications of financial development on international trade. I set up a multi-industry general equilibrium model of international trade with input-output linkages and heterogeneous firms subject to financial frictions. Industries differ in capital-intensity, which leads to differences in external finance dependence. The model is parameterized to match key features of firm-level data. Financial development leads to substantial reallocation of international trade shares from labor- to capital-intensive industries, with minor effects at the ...

COVID-19 Containment Measures, Health and the Economy
While COVID-19-related restrictions in 2020 spurred short-term rises in unemployment, states with stricter measures saw faster labor market recoveries.

International Trade Openness and Monetary Policy: Evidence from Cross-Country Data
This article studies the extent to which open economies conduct monetary policy differently from economies that are relatively closed to international trade. I first estimate country-specific Taylor rules for 26 economies, following the approach of Clarida, Gal, and Gertler (1998 and 2000). Then, I examine the extent to which open economies assign systematically different weights to changes in economic outcomes, such as inflation and the output gap, than their closed economy counterparts do. I find that open economies respond less strongly to changes in expected inflation than relatively ...

Firm Exit and Liquidity: Evidence from the Great Recession
This paper studies the role of credit constraints in accounting for the dynamics of firm exit during the Great Recession. We present novel firm-level evidence on the role of credit constraints on exit behavior during the Great Recession. Firms in financial distress, with tighter access to credit, are more likely to default than firms with more access to credit. This difference widened substantially in the Great Recession while, in contrast, default rates did not vary much by size, age, or productivity. We identify conditions under which standard models of firms subject to financial frictions ...

Artificial Intelligence and Inflation Forecasts
We explore the ability of Large Language Models (LLMs) to produce in-sample conditional inflation forecasts during the 2019-2023 period. We use a leading LLM (Google AI's PaLM) to produce distributions of conditional forecasts at different horizons and compare these forecasts to those of a leading source, the Survey of Professional Forecasters (SPF). We find that LLM forecasts generate lower mean-squared errors overall in most years, and at almost all horizons. LLM forecasts exhibit slower reversion to the 2% inflation anchor.

International Trade Policy During a Pandemic
This paper studies international trade policy during a pandemic. We consider a multi-sector small open economy model with essential and non-essential goods. Essential goods provide utility relative to a reference consumption level, and a pandemic consists of an increase in this reference level along with higher import and export prices of these goods. The economy produces domestic varieties of both types of goods subject to sectoral adjustment costs, and varieties are traded internationally subject to trade barriers. We find that trade provides limited relief to the increased demand for ...
