R&D Subsidy and Import Substitution: Growing in the Shadow of Protection
I study the effect of an innovation subsidy on the growth of firms in a developing country. Using administrative microdata for Brazil and difference-in-differences, I find that innovation subsidies drive firm growth by facilitating firm entry into high-tariff markets with domestically produced versions of foreign goods. After receiving an innovation subsidy, firms issue more patents, expand their workforce, and diversify their product line. However, these patents receive minimal citations, while also heavily citing foreign patents. Firms increase imports of foreign inputs and expand their ...

Openness and Growth: A Comparison of the Experiences of China and Mexico
In the late 1980s, Mexico opened itself to international trade and foreign investment, followed in the early 1990s by China. China and Mexico are still the two countries characterized as middle-income by the World Bank with the highest levels of merchandise exports. Although their measures of openness have been comparable, these two countries have had sharply different economic performances: China has achieved spectacular growth, whereas Mexico’s growth has been disappointingly modest. In this article, we extend the analysis of Kehoe and Ruhl (2010) to account for the differences in these ...

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 ...

Manufacturing Sentiment: Forecasting Industrial Production with Text Analysis
This paper examines the link between industrial production and the sentiment expressed in natural language survey responses from U.S. manufacturing firms. We compare several natural language processing (NLP) techniques for classifying sentiment, ranging from dictionary-based methods to modern deep learning methods. Using a manually labeled sample as ground truth, we find that deep learning models partially trained on a human-labeled sample of our data outperform other methods for classifying the sentiment of survey responses. Further, we capitalize on the panel nature of the data to train ...

Evolving comparative advantage, sectoral linkages, and structural change
I quantitatively examine the effects of location-and sector-specific productivity growth on structural change across countries from 1970-2011. The results shed new light on the ?hump shape" in industry's share in GDP across levels of development. There are two key features. First, otherwise identical changes in the composition of final demand translate differently into changes in the composition of value added because of systematic differences in sectoral linkages. Second, the mapping between sector-specific productivity and the composition of final demand systematically differs because of ...

Mind the Gap: AI Adoption in Europe and the US
This paper combines international evidence from worker and firm surveys conducted in 2025 and 2026 to document large gaps in AI adoption, both between the US and Europe and across European countries. Cross-country differences in worker demographics and firm composition account for an important share of these gaps. AI adoption, within and across countries, is also closely linked to firm personnel management practices and whether firms actively encourage AI use by workers. Micro-level evidence suggests that AI generates meaningful time savings for many workers. At the macro level, in recent ...

Digital Adoption, Automation, and Labor Markets in Developing and Emerging Economies
We document a strong negative link between self-employment and the rate of digital adoption by firms in developing and emerging economies. No link between digital adoption and the unemployment rate is found, however. To explain this evidence, we build a general equilibrium search-and-matching model with endogenous labor force participation, self-employment, endogenous firm entry, and information-and-communications technology adoption. The main finding is that changes in the cost of technology adoption per se cannot rationalize the evidence. Instead, changes in firms' barriers to entry ...

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 ...

Renewable Technology Adoption Costs and Economic Growth
We develop a dynamic general equilibrium integrated assessment model that incorporates costs due to new technology adoption in renewable energy as well as externalities associated with carbon emissions and renewable technology spillovers. We use world economy data to calibrate our model and investigate the effects of the technology adoption channel on renewable energy adoption and on the optimal energy transition. Our calibrated model implies several interesting connections between technology adoption costs, the two externalities, policy, and welfare. We investigate the relative effectiveness ...
