Ken Onishi "The Decline of Labor Share and New Technology Diffusion: Implications for Markups and Monopsony Power" [Paper] |
| Abstract | We study the mechanism behind the decline in the labor share using highly detailed plant-level data on the cement industry in Japan. Using information on the production technology in place at each plant, we find that most of the labor share decline can be explained by new technology diffusion (introduction of "New Suspension Preheater kiln"). The labor share stays constant, or even slightly increases, over time within plants of the same technology, whereas the aggregate labor share declines as production shifts to plants with a new and more capital-intensive technology. We also find that the information on plant-level technology is key to rejecting other potential hypotheses and that we would reach a qualitatively different conclusion without this information. To show this, we examine, with and without technology information, two alternative hypotheses; (i) the decline in labor share is associated with an increase in markups and (ii) firms exercise monopsony power in the labor market. We reject these two hypotheses with technology information but may not without it. |

Minji Bang (City University of Hong Kong) " Job Flexibility and Household Labor Supply: Understanding Gender Gaps and the Child Wage Penalty." |
| Abstract | This paper investigates how occupational flexibility affects married couples’ labor supply and the gender pay gap around childbirth. Using the NLSY79 data and Goldin’s (2014) measure of occupational flexibility, I show that flexibility is a significant determinant of married couples’ labor supply adjustments. When a husband’s job exhibits low flexibility, couples are more likely to specialize with the wife dropping out of the labor market and the husband increasing hours worked. In contrast, couples with greater flexibility show less labor supply adjustment to childbirth. To analyze the relationship between occupational flexibility and family-friendly labor market policies, I develop and estimate a dynamic discrete choice model of couples’ decision-making about labor supply and occupations. In the model, occupations are characterized by wage-hours schedules and flexibility levels. I find that increasing women’s and men’s own occupational flexibility increases labor force participation by 4 percentage points in the childbirth year. Interestingly, increasing husband’s flexibility has a greater impact on the wife’s labor adjustment than her own flexibility, augmenting her participation rate and working hours by 10 and 7 percentage points. Finally, I evaluate the effects of family-friendly policies providing temporary flexibility for couples experiencing a birth in the last two years. Policies that target women increase female labor supply and reduce the gender pay gap by 8% in the long run. However, when the benefits are offered to both spouses, the positive effects on the wife’s labor supply are weakened, and the gender pay gap expands in the long run. |

Mari Tanaka "Meritocracy and Its Discontents: Long-run Effects of Repeated School Admission Reforms" (Joint with Yusuke Narita and Chiaki Moriguchi) |
| Abstract | We study the impacts of changing admissions systems in higher education. Our research design takes advantage of the world's first known implementation of nationally centralized meritocratic admissions and its subsequent reversals in the early twentieth century. We find an equity-meritocracy tradeoff both in the short and long run. On the one hand, the meritocratic centralization achieve the goal of rewarding applicants with higher academic performance in the short run and produced a greater number of top bureaucratic elites in the long run. On the other hand, this meritocracy come at the distributional cost of urban-born applicants crowding out rural-born applicants from elite higher education and career advancement. Several decades later, the meritocratic centralization increases the number of urban-born top income earners and other career elites relative to rural-born elites. |
