Little is known about why cohabiting couples have fewer children than married couples. We explore the factors that explain the difference in fertility between these two groups using a switching regression analysis, which enables us to quantify the contribution of different factors through a...

China has long aimed to restrict population growth in large cities but encourages growth in small and medium-sized cities. At the same time, various government policies favor large cities. We conjecture that larger cities in China have more urban amenities and a better quality of life. We thus...

It is difficult to determine whether ghettos are good or bad, partly because racial segregation may have some effects that are unobservable. To overcome this challenge, we present a migration choice model that allows for estimating the overall effects of racial segregation. The key idea...

Rural-urban migrants in China appear to prefer nearby destination cities. To gain a better understanding of this phenomenon, we build a simple model in which migrants from rural areas choose among potential destination cities to maximize utility. The distance between a migrant's home village and...

We hypothesize that individuals with a larger social-family network are more likely to choose self-employment. We test this hypothesis using data on temporary rural-urban migrants in China. The size of a migrant’s social-family network is measured by the number of relatives and friends this...

For thousands of years, the Chinese and many other nations around the workd built defensive walls around their cities. This phenomenon is not well understood from an economic perspective. To rationalize the existence of city walls, we propose a simple model that relates the deimesions of city...

It is widely believed that unaffordable housing could drive businesses away and thus impede job growth. However, there is little evidence to support this view. This paper presents a simple model to clarify how housing affordability is linked to employment growth and why unaffordable housing...

We analyze and assess new evidence on employment dynamics from a new data source the National Establishment Time Series (NETS). The NETS offers advantages over existing data sources for studying employment dynamics, including tracking business establishment relocations that can contribute to job...

We estimate the effects of Wal-Mart stores on county-level retail employment and earnings, accounting for endogeneity of the location and timing of Wal-Mart openings that most likely biases the evidence against finding adverse effects of Wal-Mart stores. We address the endogeneity problem using...
