Working Papers

• Innovation in the presence of distortions (Job Market Paper) [draft]

Abstract: This paper studies how market distortions shape the allocation of R&D resources, and, ultimately, productivity, in a developing economy. I use a rich dataset on Colombian manufacturing firms with more than 10 employees, which provides detailed information on productivity, innovation activity, and firm-specific distortions. The data reveal that more productive firms are more likely to innovate, yet also face higher distortions. To quantify the implications, I develop and calibrate a dynamic model in which firms invest in R&D to improve productivity while facing heterogeneous distortions. The model predicts that reducing the correlation between distortions and productivity to U.S. levels increases aggregate TFP by 60%, with about one-fourth of the gains driven by dynamic mechanisms such as improved selection and better-targeted innovation. These gains arise even though the overall innovation rate remains nearly unchanged, as innovation shifts toward more productive firms. Notably, fully eliminating distortions delivers smaller marginal improvements compared to reducing their correlation with fundamentals, suggesting that the structure of distortions is more consequential than their level.

• Market liberalization and capital misallocation: The Colombian manufacturing experience

Abstract: In this paper, I develop a model to identify the contributions of adjustment costs, production uncertainty, demand uncertainty, and distortions to capital misallocation. Using data from Colombian manufacturing, I calibrate the model to estimate the relative importance of each factor. I further evaluate the impact of a market reform in Colombia by comparing sources of misallocation before and after the reform and exploring possible mechanisms by which the reform influenced misallocation. The results indicate that distortions account for the majority of capital misallocation, with a shift in significance from distortions correlated with productivity and demand to more persistent distortions. Meanwhile, adjustment costs and uncertainty play a diminished role in explaining misallocation.

• The Impact of the Russia-Ukraine War on Renewable Energy with Tasnia Hussain

Abstract: Global adoption of renewable energy has increased rapidly since the early 2000s, in part due to learning-by-doing externalities. Yet, the world falls short of net-zero goals by 2030. This paper investigates if the Russia-Ukraine war accelerated Europe's clean transition via a supply shock. The European Union relied heavily on Russia to fulfil its fossil fuel demands, particularly natural gas, for electricity generation. Countries vary in their exposure to Russian gas, experiencing the supply shock at differing intensities. We first exploit the variation in import exposure to Russian gas and find empirical evidence of more dependent countries experiencing quicker transitions post-war relative to their less-exposed counterparts. We then develop a neoclassical growth model embedding dirty and clean energy with varied fossil fuel dependency to capture general equilibrium effects. We find that a permanent fossil fuel supply shock accelerates the clean transition by four to six periods. Energy scarcity and higher energy prices increase the returns to investing in renewable electricity capital, reinforced by a boost in the learning-by-doing mechanism. In contrast, the supply shock reduces the productivity and returns of fossil fuel capital.
