Aghion, P., Bergeaud, A., Lequien, M., & Melitz, M. (2017). The Impact of Exports on Innovation: Theory and Evidence. working paper.
Abstract: A simple model of trade and innovation with heterogeneous firms predicts that a positive export shock should raise innovation more for more productive firms. Two channels coexist: the innovation effort increases for all firms because the accompanying rents increase with a firm’s market size (market size effect); the innovation effort decreases because competition toughens. This competition effect dissipates with higher firm productivity. It is therefore most salient for the least productive firms and can potentially overturn the direct market size effect. We test this prediction with patent, customs and production data covering all French firms. To disentangle the direction of causality between innovation and export performance, we construct various firm-level export demand measures. These variables capture the extent to which demand fluctuations in a firm’s foreign markets should influence its exports and through them weigh on its innovation decisions; but they remain exogenous to those firm-level decisions. We show that patenting robustly increases more with demand for initially more productive firms. This effect is reversed for the least productive firms as the negative competition effect dominates.

Liu, Ernest. "Industrial policies and economic development." (2017).
Abstract: Many developing countries adopt industrial policies that push resources towards selected economic sectors. How should countries choose which sectors to promote? I answer this question by characterizing optimal industrial policy in production networks embedded with market imperfections. My key finding is that effects of market imperfections accumulate through backward demand linkages, thereby generating aggregate sales distortions that are largest in the most upstream sectors. The distortion in sectoral sales is a sufficient statistic for the ratio between social and private marginal product of sectoral inputs; therefore, there is an incentive for a well-meaning government to subsidize upstream sectors. My sufficient statistic predicts the sectors targeted by government interventions in South Korea in the 1970s and in modern-day China.

Adamopoulos, Tasso, and Diego Restuccia. "The size distribution of farms and international productivity differences." The American Economic Review 104.6 (2014): 1667-1697.
Abstract: There is a 34-fold difference in average farm size (land per farm) between rich and poor countries and striking differences in their size distributions. Since labor productivity is much higher in large relative to small farms, we study the determinants of farm-size differences across countries and their impact on agricultural and aggregate productivity. We develop a quantitative model of agriculture and non-agriculture that features a non-degenerate size distribution of farms. We find that measured aggregate factors such as capital, land, and economy-wide productivity cannot account for more than 1/4 of the observed differences in farm size and productivity. We argue that, among the possible explanations, farm-level policies that misallocate resources from large to small farms have the most potential to account for the remaining differences. Such farm-size distortions are prevalent in poor countries. We quantify the effects of two specific policies in developing countries: (a) a land reform that imposes a ceiling on farm size and (b) a progressive land tax. We find that each individual policy generates a reduction of 3 to 7% in average size and productivity.

Abstract: Over the last 50 years, there has been a remarkable convergence in the occupational distribution between white men, women, and blacks. We measure the macroeconomic consequences of this convergence through the prism of a Roy model of occupational choice in which women and blacks face frictions in the labor market and in the accumulation of human capital. The changing frictions implied by the observed occupational convergence account for 15 to 20 percent of growth in aggregate output per worker since 1960.
