Working Paper
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 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 aggregate-level. These ...

No Credit, No Gain: Trade Liberalization Dynamics, Production Inputs, and Financial Development
We study the role of financial development on the aggregate and welfare implications of reducing import tariffs on capital and intermediate inputs. We document that financially underdeveloped economies feature a slower aggregate response following trade liberalization. We set up a quantitative general equilibrium model with heterogeneous firms subject to collateral constraints and estimate it to match salient features from Colombian plant-level data. Our model explains a substantial fraction of the differences in the empirical responses of GDP, consumption, and capital across economies with ...

International Shipping Costs: Determinants and Outlook
The COVID-19 period saw a huge rise in international shipping costs, but price pressure is likely to ease further as containerships on order are built and delivered.

No Credit, No Gain: Trade Liberalization Dynamics, Production Inputs, and Financial Development
We study the role of financial development on the aggregate and welfare implications of reducing trade barriers on imports of physical capital and intermediate inputs. We document that financially underdeveloped economies feature a slower response of real GDP, consumption, and investment following trade liberalization episodes that improve access to imported production inputs. To quantify the role of financial development, we set up a quantitative general equilibrium model with heterogeneous firms subject to financial constraints and estimate it to match salient features from Colombian ...
Employment Losses in Contact-Intensive Industries
The COVID-19 pandemic has had uneven effects on employment across industries. Nonessential contact-intensive industries have experienced the largest job losses.

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 ...

Artificial Intelligence and Inflation Forecasts
We explore the ability of Large Language Models (LLMs) to produce 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. We argue that this method of generating forecasts is inexpensive and can be ...

What Happens When Countries Increase Tariffs?
This essay investigates the potential impact of higher U.S. tariffs on the U.S. economy. To do so, we investigate the evolution of key macroeconomic variables following past episodes of tariff increases across a large number of countries.
Immigrant Workers and U.S. Trade Activity
States with higher shares of immigrant workers in the manufacturing sector are more likely to trade more in manufactured goods.

Trade Adjusts Gradually After Trade Liberalization
In recent years, the impact of international trade liberalization on economic outcomes such as output, investment, and employment has been at the forefront of political and economic discussions.
