Cross-border Patenting, Globalization, and Development
We build a stylized model that captures the relationships between cross-border patenting, globalization, and development. Our theory delivers a gravity equation for cross-border patents. To test the model’s predictions, we compile a new dataset that tracks patents within and between countries and industries, for 1980-2019. The econometric analysis reveals a strong, positive impact of policy and globalization on cross-border patent flows, especially from North to South. A counterfactual welfare analysis suggests that the increase in patent flows from North to South has benefited both ...

The Micro and Macro Dynamics of Capital Flows
We study empirically and theoretically the effects of international financial flows on resource allocation. Using the universe of firms in Hungary, we show that removing capital controls lowers firms’ cost of capital and increases household consumption, with the latter playing a dominant role. The consumption channel leads to reallocation of resources toward high expenditure elasticity activities—such as services—promoting both the expansion of incumbents and firm entry. A multi-sector heterogeneous firm model replicates these dynamics. Our model shows that non-homotheticity in ...

Cross-border Patenting and the Margins of International Trade
This paper investigates the impact of cross-border patenting on the margins of international trade using disaggregated data on international patenting and trade flows. We develop a theoretical framework of trade and firms' patenting decisions that motivates our empirical analysis. The main results reveal that cross-border patenting has a larger effect on the extensive margin of trade compared to the intensive margin. This finding suggests that firms tend to seek patent protection in international markets prior to entering those markets with new products, rather than with their existing ...

Diffusion of Containerization
This paper uses a newly constructed, comprehensive dataset to investigate the diffusion of containerization. The data show that country adoption is exceptionally fast while firm usage increases more slowly. To guide my empirical investigation, I build a multi-country trade model with endogenous adoption of a new transportation technology that is consistent with these facts. I then test empirically the predictions of the model and find that: (1) usage of containerization increases with firms' fixed costs and the size and average income of the container network; and (2) adoption depends on ...

Technology, Geopolitics, and Trade
We study how geopolitical fragmentation shapes cross-border technology licensing and innovation incentives. We show that bilateral royalty flows vary with geopolitical distance differently from goods trade, and that this relationship depends on intellectual property enforcement. To interpret these facts, we develop a growth-trade model in which geopolitical risk weakens licensing enforceability when intellectual property rights are poorly protected. Royalty payments reflect both technology adoption and licensing prices: weaker enforcement can reduce diffusion while inducing firms to reprice ...

Cross-border Patenting, Globalization, and Development
We build a quantitative model that captures the relationships between cross-border patenting, globalization, and development. Our theory delivers a ‘structural gravity’ equation for cross-border patents. To test the model’s predictions, we compile a new dataset that tracks patents within and between countries and industries over time. The econometric analysis reveals a strong, positive impact of policy and globalization on cross-border patent flows between 1995 and 2018, especially from North to South. A counterfactual analysis shows these North-to-South flows benefited both regions, ...

Technology, Geopolitics, and Trade
We study how geopolitical shocks reshape innovation through the contractual structure of cross-border technology adoption. Empirically, royalty flows are more sensitive than goods trade to geopolitical distance, especially where intellectual property enforcement is weak. We build a growth-trade model in which political risk raises breach hazards in licensing contracts. Firms reprice royalties but compliant adoption declines, and innovation incentives respond to the joint evolution of price and quantity. Quantitatively, fragmentation reallocates innovation and lowers the balanced-growth path ...

The Local Impact of Containerization
We investigate how containerization impacts local economic activity. Containerization is premised on a simple insight: packaging goods for waterborne trade into a standardized container makes them dramatically cheaper to move. We use a novel cost-shifter instrument -- port depth pre-containerization -- to contend with the non-random adoption of containerization by ports. Container ships sit much deeper in the water than their predecessors, making initially deep ports cheaper to containerize. Consistent with New Economic Geography models, we find that counties near container ports grow an ...

Technology, Geopolitics, and Trade
We study when unilateral export controls are optimal by quantifying how geopolitical rivalry reshapes trade in ideas. Empirically, cross-border technology flows are far more sensitive than goods trade to geopolitical distance, especially where IPR is weak, and these penalties intensify after 2017. Motivated by this evidence, we build a growth–trade model in which geopolitical distance raises breach risk in licensing; firms partially reprice risk via higher royalties but cannot fully insure quantities. In a consumption-only benchmark, a permanent rise in US–China geopolitical distance ...
