According to the Population Census of Taiwan in 2000, there are1.23 million Units of vacant houses in Taiwan, which is quite near to Chang, et al (2000)'s estimation. Though the problem of excess dwelling units is quite serious, there are little studies on relevant topics in Taiwan, not mention studying spccifical1y on housing inventories held by the housing developers. Since the developers' housing inventories have a direct impact on housing market and housing price, it is meaningful to pay more attention to study the determinants of the deve1opers' housing inventories in Taiwan. Applying a data set from the Land Bank of Taiwan, this paper analyzes the situation of housing inventories of 768 housing developers in Taiwan. In order to avoid the problem of sample selection bias, we apply the Heckman two-stage mode1 to estimate the probabi1ity whether a developer wi11 have housing inventories or not. Then, we estimate the impact of the determinants on the developers' housing inventories. We find that all of total sales, location, local market situation, type of housing units, and selling method have significant impacts on housing inventories. Furthermore, we also find that the estimated coefficient of inverse Mill's ratio is also significant, which shows that we might get a serious sample selection bias if we do not use the Heckman two-stage model to correct our sample. |
