Using firm panel and satellite-derived pollution data, I estimate the effect of pollution on productivity, with wind velocity serving as an instrument for air pollution. While sensitivity is detected among labor-intensive industries, no meaningful average effect is found. To explain these patterns, I present a model showing that firms adapt by lowering output to mitigate pollution damages and that industries’ production technology contributes to heterogeneity. Applying the model, I estimate that a one standard deviation increase in the labor intensity of production technology results in a 0.6 percentage point greater negative impact of pollution on productivity. The findings imply that the damages of pollution to profits are twice as high among adversely affected industries than the average and four times higher when inputs remain fixed relative to when they adapt.</div></div>","PeriodicalId":48418,"journal":{"name":"Journal of Development Economics","volume":"179 ","pages":"Article 103597"},"PeriodicalIF":4.6,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145158866","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This suggests that carbon mitigation can occur alongside economic growth. Emissions reduction was achieved through broad structural transformation and green technologies adoption, rather than green innovation. Effects are more pronounced in regions with greater power sector competition and stronger local state capacity. Finally, we find no evidence of carbon leakage to neighboring areas or to cities with close production ties to ETS cities.</div></div>","PeriodicalId":48418,"journal":{"name":"Journal of Development Economics","volume":"179 ","pages":"Article 103631"},"PeriodicalIF":4.6,"publicationDate":"2025-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145119159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using rare surnames to follow lineages of ethnic minorities and elites from the colonial era to the early 20th century, we analyze whether ancestry predicts access to educational institutions. Our findings reveal strong correlations: Students with Afro-Colombian or Indigenous surnames are less likely to be enrolled in high-quality schools and more likely to be attending low-quality schools, while those with elite surnames show the opposite pattern. Although we observe regression to the mean for some historical elites, privileged access to education holds over time for persistent elites. We explore assortative mating as a mechanism behind this persistence in inequality of opportunity. We find that marriage patterns differ significantly between attendees of high- and low-quality schools, with homogamy reinforcing educational disparities.

This study uses data from India – where a demonetization policy led to a large increase in digital payments – to examine the impacts of digitalization on firms across sectors in a developing country in the short run. I find that service firms experienced growth in income and productivity while manufacturing firms witnessed a decline. I then explore the mechanisms driving this divergence. The results show that service firms invested more in information and communications technology (ICT) capital and hired more complementary skilled ICT labor, whereas manufacturing firms did not. Notably, this influx of skilled ICT workers into the service sector was drawn from the manufacturing sector due to limited spatial labor mobility. During this period, wages for ICT labor were driven up while remaining stagnant for other workers. These findings underscore how digitalization, in the presence of labor market constraints, can exacerbate short-term sectoral divergence in productivity growth and shed light on its impacts on the growth trajectories of developing countries.</div></div>","PeriodicalId":48418,"journal":{"name":"Journal of Development Economics","volume":"179 ","pages":"Article 103618"},"PeriodicalIF":4.6,"publicationDate":"2025-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145050015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We show that this difference can be explained by the inability of firms facing NTMs to take advantage of cheaper intermediate inputs from China in the face of depreciations of the Yuan, consistent with a model where NTMs impose fixed costs of import.
