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 ...

Markets, Externalities, and the Dynamic Gains of Openness
Inflows of foreign knowledge are the key for developing countries to catch up with the world technology frontier. In this paper, I construct a simple tractable model to analyze (a) the incentives of foreign firms to bring their know-how to a developing country and (b) the incentives of domestic firms to invest in their own know-how, given the exposure to foreign ideas and competition. The model embeds two diffusion mechanisms typically considered separately in the literature: externalities and markets. The dynamic gains of openness can be substantial under either mechanism, but their relative ...

The dual nature of trade: measuring its impact on imitation and growth
Imports of goods that embody foreign technology raise a country's output directly as inputs into production and indirectly through reverse-engineering of these goods, which contributes to domestic imitation and innovation. This paper first quantifies spillovers from high-technology imports from developed countries to domestic imitation and innovation in both developed and developing countries. It then considers the contribution of foreign and domestic innovation to real per capita GDP growth. ; International patent data for forty countries from 1970 to 1985 are used to create proxies for ...

Mega Firms and New Technological Trajectories in the U.S.
We provide evidence that mega firms have played an increasingly important role in shaping new technological trajectories in recent years. While the share of novel patents---defined as patents introducing new combinations of technological components---produced by mega firms declined until around 2000, it has rebounded sharply since then. Furthermore, we find that the technological impact and knowledge diffusion of novel patents by mega firms have grown relative to those by non-mega firms after 2001. We also explore potential drivers of this trend, presenting evidence that the rise in novel ...

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 ...

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 ...

Openness and the Optimal Taxation of Foreign Know-How
Developing countries frequently offer tax incentives and even subsidize the entry and operation of foreign firms. I examine the optimality of such policies in an economy where growth is driven by entrepreneurial know-how, a skill that is continuously updated on the basis of the productive ideas implemented in the country. Openness allows foreign ideas to disseminate inside a country and can foster the country's domestic accumulation of know- how. With externalities, however, laissez-faire openness is suboptimal and can be growth-and even welfare-reducing. I examine the gains from openness ...
