第1報告(14:00~15:30)
佐野 ジェイコブ 氏(早稲田大学)Technology, Skill Prices, and Wage Inequality
Abstract:
Skill-biased technical change is a leading explanation for rising wage inequality between education groups, yet it has struggled to account for changes in inequality within them. We argue that this limitation arises from treating skill as a single dimension. While the college premium depends on differences in average skill bundles across education groups, within-group wage dispersion depends on the distribution of those skills and their market prices. Using O*NET data and hierarchical clustering, we construct four granular skill dimensions: socio-cognitive, management, STEM, and dexterity. We then use these skill measures to examine how the expansion of work from home (WFH) and the diffusion of generative AI are associated with changes in the returns to individual skills. Although both technologies exhibit positive education-based skill bias, difference-in-differences estimates reveal distinct patterns of skill repricing. WFH exposure is associated with higher returns to management skills and lower returns to STEM skills, whereas generative AI exposure is associated primarily with higher returns to socio-cognitive skills. Over the corresponding periods, residual wage dispersion among college-educated workers declines from 2019 to 2022 and increases from 2022 to 2025. A counterfactual decomposition shows that changes in skill prices account for approximately 41% of the earlier decline and 23% of the later increase in residual wage variance.

山本 明日香 氏(九州大学)Riots, Child Health, and Gender Bias in India (with Katsushi Imai & Bina Agarwal)
Abstract:
Gender inequality in human capital remains a major concern in developing countries. This study examines whether prenatal exposure to riots affects early-life health in India and whether these effects vary by child sex and regional gender bias. Using geocoded data on riots and child and maternal health, we find that prenatal riot exposure is associated with poorer child health overall, while riot fatalities are associated with a higher likelihood of pregnancy termination. The adverse effects on child health are generally larger for boys. However, this male disadvantage becomes smaller in areas with lower ratios of girls to boys, consistent with relatively greater disadvantage for girls in regions with stronger gender bias. This may reflect lower household resource allocation to girls in such areas. These findings show that prenatal shocks interact with both biological vulnerability and gender-biased social environments.
