Female Labor Supply in Japan: Implications of the Informal Sector for Labor Force Participation and Hours of Work
研究日本已婚女性（包括雇员和家庭工人）的劳动参与和工作时间决策，估计了东京都市区样本的三项参与模型，发现雇员的工资和收入弹性略高于美国，但丈夫收入对雇员年工作时间有意外正向影响，且家庭工人的弹性通常较大。
This paper extends previous work on labor supply in Japan by treating the simultaneous labor force participation and hours of work decisions for Japanese wives, both employees and family workers. It estimates a trichotomous participation model for a sample from the Tokyo Metropolitan Area, and then estimates hours and wage equations, and aggregate labor supply elasticities. The empirical results generally confirm the economic model's theoretical predictions. Although the estimated aggregate wage and income elasticities for employees are somewhat higher than previous estimates for the U.S., they are of the same order of magnitude. However, the level of the husband's income has an unexpected positive effect on the annual hours that employees work and the elasticities estimated for family workers are usually large.
