Family economics uses economic concepts such as productions and decision making to understand family behavior. Economists place emphasis on the rule of families on labor supply, human capital investment, and consumption. In a household, the members choose the optimal time allocations between working, housework and leisure, and money between consumption of different members and savings. One-Child policy and strong inter-generational connections cause unique family structure in China. Households of different generations provide income transfer and labor support to each other. Households consider these connections in their savings, labor supply, human capital investment, fertility and marriage decisions. Especially, strong intergenerational relationships in China are one cause of the high level of young female labor supply and high saving rate. I will investigate the rules of intergenerational relationships on household economic behavior.

Affirmative Action allocates college seats to a separate group. To evaluate the distribution effects of AA on discrete groups, we need to study household's strategic reactions on the rule of college seats allocation. The admission system of National College Entrance Examination in China is a type of AA. That distributes college seats by regions. I will use the rapid expansion of Chinese college enrollment as a natural experiment to check the households' reaction on AA and college expansion.

Media economics utilizes economic empirical and theoretical tools to figure out the social, cultural, and economic issues in media industries. The impact of online piracy on genuine products sales is under debate, because people cannot find representing proxies to evaluate piracy levels. I will use Chinese data to study the effects of online piracy on theater revenue.
