Group lending has been widely adopted in the past thirty years by many microfinance institutions as a means to mitigate information asymmetries when delivering credit to the poor. This paper proposes an empirical method to address the potential omitted variable problem resulting from unobserved...

This paper uses the 2008 Wenchuan earthquake in China as a natural experiment to examine how the housing market reacted to this unforeseen, extreme event. We use a unique transaction dataset for new (under construction) apartment units to analyze the pricing behavior of units in lower versus...

Agglomeration is a location pattern frequently observed in service industries such as hotels. This paper empirically examines if agglomeration facilitates tacit collusion in the lodging industry using a quarterly dataset of hotels that operated in rural areas across Texas between 2003 and 2005....

Information is a crucial ingredient in economic decision making. Yet measuring the extent of information exchange among individuals and its effect on economic outcomes is a difficult task. We use the universe of de-identified cellphone usage records from more than one million users in a Chinese...

China's fast economic growth over the past 40 years has been accompanied by an increasingly rapid rate of urbanization, from about 20% in the early 1980s to 60% in 2018. In addition to natural population growth, rural-urban migration is generally believed to be a dominant driving force....

In this paper, we propose a matching model to study the efficiency of thin and thick markets. Our model shows that the probabilities of matches in a thin market are significantly lower than those in a thick market. When applying our results to a job search model, it implies that, if the ratio of...

This paper investigates whether subjective expectations about future mortality affect consumption and bequests motives. We estimate a dynamic life-cycle model based on subjective survival rates and wealth from the panel dataset Asset and Health Dynamics among Oldest Old. We find that bequest...

Testing life-cycle models and other economic models of saving and consumption at micro level requires knowledge of individuals' subjective believes of their mortality risk. Previous studies have shown that individual responses on subjective survival probabilities are generally consistent with...

This paper investigates to what extent the differences in education between black and white men can be explained by the differences in their mortality risks. A dynamic optimal stopping-point life cycle model is examined, in which group-level mortality risk plays an important role in determining...

This paper studies how the thick market effect influences local unemployment rate fluctuations. The paper presents a model to demonstrate that the average matching quality improves as the number of workers and firms increases. Unemployed workers accumulate in a city until the local labor market...
