中国的金融制度变迁也服从了渐进改革的“过渡性”逻辑 ,渐进战略较好地支持了中国 2 0年的经济增长。但是 ,由于“双轨”体制的固有矛盾 ,使中国的金融改革在今天聚集到了深层次的金融改革上 ,而这一问题的核心是多元化的金融产权关系。中国加入WTO成为中国金融深化改革的契机。摆在面前的来自外部世界的竞争 ,成为推进中国金融业“对内开放”的巨大的外部冲击  相似文献

This paper contains an empirical study of the rental term structure in a property market that included a dramatic boom and bust cycle. The study is applied to office leases in commercial properties located in Stockholm CBD, Sweden. The time period under study is 1977–1991. The number of observations (lease contracts) that we were able to make full use of in the regression analyses is n=861. For seven out of fifteen years studied, a significant term structure was observed. The estimated hedonic rent equation was also used to construct an office rental index.  相似文献

This paper is motivated by automated valuation systems, which would benefit from an ability to estimate spatial variation in location value. It develops theory for the local regression model (LRM), a semiparametric approach to estimating a location value surface. There are two parts to the LRM: (1) an ordinary least square (OLS) model to hold constant for interior square footage, land area, bathrooms, and other structural characteristics; and (2) a non-parametric smoother (local polynomial regression, LPR) which calculates location value as a function of latitude and longitude. Several methods are used to consistently estimate both parts of the model. The LRM was fit to geocoded hedonic sales data for six towns in the suburbs of Boston, MA. The estimates yield substantial, significant and plausible spatial patterns in location values. Using the LRM as an exploratory tool, local peaks and valleys in location value identified by the model are close to points identified by the tax assessor, and they are shown to add to the explanatory power of an OLS model. Out-of-sample MSE shows that the LRM with a first-degree polynomial (local linear smoothing) is somewhat better than polynomials of degree zero or degree two. Future applications might use degree zero (the well-known NW estimator) because this is available in popular commercial software. The optimized LRM reduces MSE from the OLS model by between 5 percent and 11 percent while adding information on statistically significant variations in location value.  相似文献

Properties can be bought by government agencies, land trusts, or private entities for conservation and preservation purposes, such as farmland preservation, wildlife refuges, other conservation, and cultural and historical preservation. There is variation in the dollars paid per acre across properties and across buyer type. An option value model based on future potential land uses is used to explain much of this variation. The data used in our analysis is sales transactions data for conservation and preservation purposes from throughout the United States. We find that much of the value of conservation properties is derived from future potential land uses, including housing, timber, recreation, and conservation. We confirm that public versus private buyers value options differently, which makes sense from a public good point of view, if markets are thin.  相似文献

The Announcement Effect of an Airport Expansion on Housing Prices   总被引:2,自引:0,他引:2  
The purpose of this study is to examine the influence of the announcement of a new airport hub on housing prices near the airport. While numerous studies of airport noise have found that high noise levels reduce property values, few have been able to measure the announcement effect on values. The results indicate that after controlling to extraneous influences, housing property prices in a 2.5 mile band from the Greensboro/High Point/Winston Salem metropolitan airport declined approximately 9.2% in the post-announcement period. In the next 1.5-mile band, house prices declined approximately 5.7% in the post-announcement period.  相似文献
