This paper studies the urban land market in China in 2003--2007. In China, all urban land is owned by the state. Leasehold use rights for land for (re)development are sold by city governments and are a key source of city revenue. Leasehold sales are viewed as a major venue for corruption, prompting a number of reforms over the years. Reforms now require all leasehold rights be sold at public auction. There are two main types of auction: regular English auction and an unusual type which we call a "two stage auction". The latter type of auction seems more subject to corruption, and to side deals between potential bidders and the auctioneer. Absent corruption, theory suggests that two stage auctions would most likely maximize sales revenue for properties which are likely to have relatively fe...

This paper provides a search model for housing market where the number of buyers and/or sellers plays very important role. The model makes three testable predictions: (1) the unemployment rate has a negative impact on the trading volume and the sale prices of the housing market; (2) a larger housing market has a lower average sale price, shorter time-to-sale and smaller price dispersion, in addition to a lower vacancy rate. (3) In a larger housing market, when the unemployment rate goes up (or down), the sale price decreases (or increases) by a smaller percentage than in a smaller market. All three predictions are supported by a panel dataset of the Texas city-level housing markets.

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 reaches a critical minimum size, which leads to cyclical fluctuations in the local unemployment rates. Since larger cities attain the critical market size more frequently, they have shorter unemployment cycles, lower peak unemployment rates, and lower mean unemployment rates. Our empirical tests are consisten with the predictions of the model. In particular, we find that an increase of two standard deviations in city size shortens the unemployment cycles by about 0.72 months, lowers the peak unemplo...
