Capital market integration and gender inequality

This study explores the effects of globalization on gender inequality. Specifically, we describe how, in terms of capital market integration, globalization alters the gender gap in wage rates through changes in labor demand for capital‐intensive sectors. Consequently, via changes in the bargaining positions of men and women, globalization leads to opposite effects on the couple's labor supply and fertility decisions in capital‐importing and capital‐exporting countries. Moreover, by considering the properties of the industrial structures of capital‐importing and capital‐exporting countries, we show that globalization induces empirically observed declines in fertility rates throughout the world.     

The prodigal son: does the younger brother always care for his parentsin old age?

Studies have shown that the older sibling often chooses to live away from his elderly parents intending to free ride on the care provided by the younger child. In the presented model, we incorporate income effects and depict a different pattern frequently observed in Eastern countries; that is, the older sibling lives near his or her parents and takes care of them in old age. By generalizing the existing model, we show three cases of elderly parents being looked after by (i) the older sibling, (ii) the younger sibling, and (iii) both siblings, depending on the relative magnitude of the income effect and the strategic incentive for one sibling to free ride on the other. Our study also investigates the effect of changes in relative income on the level of total care received by parents.     

Stochastic accumulation of human capital and welfare in the Uzawa–Lucas model: an analytical characterization

Stochastic growth models are often solved numerically, because they are not tractable in general. However, recent several studies find the closed-form solution to the stochastic Uzawa–Lucas model in which technological progress or population dynamics follow a Brownian motion process with one or two parameter restriction(s). However, they assume that the return on the accumulation of human capital is deterministic, which is inconsistent with empirical evidence. Therefore, I develop the Uzawa–Lucas model in which the accumulation of human capital follows a mixture of a Brownian motion process and many Poisson jump processes, and obtain the closed-form solution. Moreover, I use it to examine the nexus between human capital uncertainty, technological progress, expected growth rate of human capital, and welfare.
