Using dynamic panel estimation techniques on a sample consisting of both developed and developing countries, the analysis finds that financial development generally exacerbates income and wealth inequality.

Our analysis explores four behavioral mechanisms: interpersonal needs and relationships, parent-child interactions, teacher-student dynamics, and time allocation. We demonstrate that online education reduces effective peer interaction, deteriorates self-reported interpersonal and familial relationships, and leads to inefficient time allocation.

Using a multi-method strategy, I examine per capita income dynamics after tariff reductions in a panel of 161 countries from 1960 to 2019. Baseline local projections reveal a sharp divergence: GDP per capita rises in manufacturer countries following tariff reductions, and notably falls in nonmanufacturers. A local projections difference-in-differences framework strengthens the analysis by accounting for treatment effect heterogeneity and variation in treatment timing. Finally, I study tariff reductions during the WTO-era reform period (1986 to 1994), a policy episode that historical evidence supports as plausibly exogenous, providing complementary evidence that confirms the observed heterogeneity. An exploration of mechanisms using local projections links these patterns to shifts in productivity, capital stocks, and manufacturing shares in GDP, consistent with theoretical expectations. The findings suggest that rising protectionism in manufacturer countries may be harmful, while further liberalization in nonmanufacturers could have unintended consequences.</div></div>","PeriodicalId":48183,"journal":{"name":"Journal of Comparative Economics","volume":"54 1","pages":"Pages 99-115"},"PeriodicalIF":3.1,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147419275","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We hypothesize that increased female participation in these protests improved women’s empowerment and helped reduce missing women. Using a difference-in-differences analysis, our identification strategy is based on protest intensity heterogeneity, and changes in missing women for the age group of [0–1] before and after the protests across different governorates in urban and rural areas. We find convincing causal evidence that the number of missing women decreased significantly in high protest intensity governorates. Based on protest heterogeneity across different periods, we also show that this effect was most visible after the fourth and final phase of protests.

Further analyses suggest that these reductions are primarily driven by a reduction in blood-borne transmission. In contrast, the effect of CSL on sexual transmission is ambiguous. Drawing on detailed data on individuals’ sexual behaviors and attitudes toward sex and fertility, we find that the CSL significantly lowers women’s desired fertility without affecting that of men. Consequently, women become the more active contraception seekers within households, leading to a substitution of female-controlled contraceptive methods for condoms. This behavioral shift may increase the risk of sexually transmitted infections, potentially offsetting or even muting the CSL’s positive effect on reducing the sexual transmission of HIV/AIDS.</div></div>","PeriodicalId":48183,"journal":{"name":"Journal of Comparative Economics","volume":"54 1","pages":"Pages 164-193"},"PeriodicalIF":3.1,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147420312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
