Financial Frictions and International Trade

This paper reviews recent studies on the impact of financial frictions on international trade. We first present evidence on the relation between measures of access to external finance and export decisions. We then present an analytical framework to analyze the impact of financial frictions on firms' export decisions. Finally, we review recent applications of this framework to investigate the impact of financial frictions on international trade dynamics across firms, industries, and in the aggregate. We discuss related empirical, theoretical, and quantitative studies throughout.

Navigating the Waves of Global Shipping: Drivers and Aggregate Implications

This paper studies the drivers of global shipping dynamics and their aggregate implications. We document novel evidence on the dynamics of global shipping supply, demand, and costs. Motivated by this evidence, we set up a dynamic model of international trade with a global shipping market where shipping firms and importers endogenously determine shipping supply and costs. We find the model successfully accounts for the dynamics of global shipping observed in the aftermath of COVID-19 as well as at business cycle frequencies. We find that accounting for global shipping is critical for the ...

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 ...

Firms in international trade

Firms play a critical role in the global economy. In this paper, we survey the behavior of firms in the international economy, both in theory and in the data. We first summarize the key empirical facts that motivate the study of firms in trade. Then, we detail recent theoretical developments on the micro-foundations of firm behavior in an international context, focusing on how firms select into exporting, and how firms respond to international shocks. Finally, we turn to a ?real world,? empirically focused view of exporting, beginning with the growth dynamics of firms expanding to global ...

The Effects of Terror on International Air Passenger Transport: An Empirical Investigation

This paper presents a theoretical model (adapted from the structural gravity model by Anderson and van Wincoop, 2003) to capture the effects of terrorism on air passenger traffic between nations affected by terrorism. We then use equations derived from this model, in conjunction with alternative functional forms for trade costs, to estimate the effects of terrorism on bilateral air passenger flows from 57 source countries to 25 destination countries for the period of 2000 to 2014. We find that an additional terrorist incident results in approximately a 1.2% decrease in the bilateral air ...

Shortages of Critical Goods in a Global Economy: Optimal Trade and Industrial Policy

This paper studies the role for optimal trade and industrial policy to mitigate shortages of critical goods following global shocks. We develop a dynamic model of trade with producers of essential and non-essential goods owned by heterogeneous households under incomplete markets. Shocks that increase global demand for critical goods lead to underinvestment relative to an economy with a representative household or complete markets. Trade exacerbates the shock as producers reallocate domestic sales toward exports. Shortages can be mitigated, increasing welfare, by taxing exports while ...

Knowledge Diffusion, Trade and Innovation across Countries and Sectors

We provide a unified framework for quantifying the cross country and cross-sector interactions among trade, innovation, and knowledge diffusion. We study the effect of trade liberalization in a multi-country, multi-sector endogenous growth model in which comparative advantage and the stock of knowledge are determined by innovation and diffusion. A reduction in trade costs induces a re-allocation of comparative advantage in production and innovation across sectors, which translates into higher growth along the counterfactual balanced growth path (BGP). Heterogeneous knowledge diffusion across ...

International trade and labor reallocation: misclassification errors, mobility, and switching costs

Over the last few decades, international trade has increased at a rapid pace, altering domestic production and labor demand in different sectors of the economy. A growing literature studies the heterogeneous effects of trade shocks on workers’ employment and on welfare when reallocation decisions are costly. The estimated effects critically depend on data on workers’ reallocation patterns, which is typically plagued with coding errors. In this paper, I study the consequences of misclassification errors for estimates of the labor market effects of international trade and show that ...

The Economic Impact of COVID-19 around the World

This article provides an account of the worldwide economic impact of the COVID-19 shock. In 2020, it severely impacted output growth and employment, particularly in middle-income countries. Governments responded primarily by increasing expenditure, supported by an expansion of the supply of money and debt. These policies did not put upward pressure on prices until 2021. International trade was severely disrupted across all regions in 2020 but subsequently recovered. For 2021, we find that the adverse effects of the COVID-19 shock on output and prices were significant and persistent, ...

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 ...
