Technology, Geography, and Trade over Time: The Dynamic Effects of Changing Trade Policy
I study the dynamic effects of changes in trade policy in a multi-country model with firms that make durable and destination-specific investments in exporting capacity. Using Mexican exporter-level data, I show that incumbent exporters to minor trade partners account for a smaller share of bilateral exports than do incumbent exporters to major trade partners, indicating a systematic difference in the persistence of the export decision across destinations. The model is calibrated to capture the positive relationship between exporting persistence and export volume, and predicts that trade ...

Investment Responses to Trade Liberalization : Evidence from U.S. Industries and Establishments
This paper examines the effect of a change in U.S. trade policy on the domestic investment of U.S. manufacturers. Using a difference-in-differences identification strategy, we find that industries more exposed to reductions in import tariff uncertainty exhibit relative declines in investment after the change in trade policy. Within industries, we find that this relationship is concentrated among establishments with low initial levels of labor productivity, capital intensity and skill intensity. For plants with high initial levels of skill intensity, we find that increased exposure is ...

Innovation and Trade Policy in a Globalized World
How do import tariffs and R&D subsidies help domestic firms compete globally? How do these policies affect aggregate growth and economic welfare? To answer these questions, we build a dynamic general equilibrium growth model where firm innovation endogenously determines the dynamics of technology, market leadership, and trade flows, in a world with two large open economies at different stages of development. Firms? R&D decisions are driven by (i) the defensive innovation motive, (ii) the expansionary innovation motive, and (iii) technology spillovers. The theoretical investigation illustrates ...

To Find Relative Earnings Gains After the China Shock, Look Upstream and Outside Manufacturing
We find that US workers outside manufacturing exhibit relative earnings increases after US trade liberalization with China. These relative gains cumulate over time as the beneficial effect of a workerâ s upstream exposureâ increased competition from China in input marketsâ more than offsets the detrimental impact of her own and downstream (customer) exposures. These relative gains are smaller for non-manufacturing workers with less ex ante firm tenure and lower initial earnings, and are absent among manufacturing workers due to a lack of upstream gains and stronger downstream losses.

The Macroeconomic Effects of Trade Policy
We study the short-run macroeconomic effects of trade policies that are equivalent in a friction-less economy, namely a uniform increase in import tariffs and export subsidies (IX), an increase in value-added taxes accompanied by a payroll tax reduction (VP), and a border adjustment of corporate pro.t taxes (BAT). Using a dynamic New Keynesian open-economy framework, we summarize conditions for exact neutrality and equivalence of these policies. Neutrality requires the real exchange rate to appreciate enough to fully offset the effects of the policies on net exports. We argue that a ...

What is Certain about Uncertainty?
Researchers, policymakers, and market participants have become increasingly focused on the effects of uncertainty and risk on financial market and economic outcomes. This paper provides a comprehensive survey of the many existing measures of risk, uncertainty, and volatility. It summarizes what these measures capture, how they are constructed, and their effects, paying particular attention to large uncertainty spikes, such as those appearing concurrently with the outbreak of COVID-19. The measures are divided into three types: (1) news-based, survey- based, and econometric; (2) asset market ...

Why is Trade Not Free? A Revealed Preference Approach
A prominent explanation for why trade is not free is politicians’ desire to protect some of their constituents at the expense of others. In this paper we develop a methodology that can be used to reveal the welfare weights that a nation’s import tariffs implicitly place on different groups of society. Applied in the context of the United States in 2017, this method implies that redistributive trade protection accounts for a significant fraction of US tariff variation and causes large monetary transfers between US individuals, mostly driven by differences in welfare weights across sectors ...

Disruptions to Foreign Trade and U.S. Banks’ Returns
We develop a market-based measure of firms' and industries' exposure to foreign trade disruptions. Combining this approach with detailed supervisory data, we quantify large U.S. banks' exposure to such disruptions and propose a novel bank-level vulnerability index. We show that banks with greater exposure experienced significantly larger stock price declines following the April 2025 tariff announcements. Our vulnerability index explains 18% of the cross-sectional variation in bank returns during this episode.

The Design and Effect of Tariff Retaliation: Evidence from the European Union
We show that the EU's 2018 retaliation against US steel and aluminum tariffs targeted goods with low US import dependence and high substitutability. For the majority of tariffed goods, the US share of EU imports declined notably and remained below pre-2018 levels even after the retaliatory tariffs were lifted, reflecting asymmetric effects of tariffs on trade diversion. Moreover, although the retaliatory tariffs were instantly and fully passed through to EU importers, the retaliation did not lead to domestic price pressures as we find no evidence for inflationary effects on consumer and ...
