Chapter 1 studies favoritism towards in-group members using cooperative games in natural villages in Yunnan, China. We found tendencies of favoritism towards co-ethnics but only when other groups are present. This favoritism can bring adverse effects on cooperation especially when group composition is unbalanced.

Chapter 2 studies study the effectiveness of merit-based migration policies when we consider the interaction between migration and marriage decisions. I first show that individual strategic marriage responses amplify policy impact on migrant inflow but weaken the impact on migrant composition. I apply the model to Chinese data and reforms on hukou registration. Aligned with the theoretical predictions, I show that we would substantially underestimate the migrant inflows to big cities in China if the main migration restrictions (hukou system) would be removed at all.

Chapter 3 examines individual migration responses to air pollution information disclosure. We exploit the roll-out of an influential national air quality monitor installation program in China and the variation in regional pollution before the program. We show that population pollution elasticity increases by 9% due to pollution information disclosure. Among the change, 10% is driven by rising environmental regulations through labor demand, and 90% is driven by the improved perception of health risk
