Job and vacancy competition in empirical matching functions

We investigate job competition among job seekers and vacancy competition among firms extending the job competition model proposed by Anderson and Burgess (Anderson, P.M., Burgess, S.M., 2000. Empirical matching functions: Estimation and interpretation using state level data. Review of Economics and Statistics 82, p. 90–102). Our results for data from West Germany provide evidence for both phenomena, thereby extending and qualifying previous insights.     

Foreclosure,vacancy and crime

This paper examines the impact of residential foreclosures and vacancies on violent and property crime. To overcome confounding factors, a difference-in-difference research design is applied to a unique data set containing geocoded foreclosure and crime data from Pittsburgh, Pennsylvania. Results indicate that while foreclosure alone has no effect on crime, violent crime rates increase by roughly 19% once the foreclosed home becomes vacant – an effect that increases with length of vacancy. We find weak evidence suggesting a potential vacancy effect for property crime that is much lower in magnitude.     

广佛同城对佛山房地产业的影响研究

应用房地产增加值、房地产投资额、自然空置率、房价收入比等指标对佛山房地产业进行研究,并运用GM(1,1)模型对房价进行预测。根据房地产业与区域经济的关系,探索广佛同城对佛山房地产的影响,发现佛山房地产业的发展空间大、投资合理、需求稍大于供求、房价稍高的状况。结果表明佛山房地产业在受广佛同城化的影响下发展是比较健康的,同时对研究发现的问题提出建议。     

商品房空置率过高的价格因素分析

近年业，我国住房制度改革倍受各界瞩目，在房改进程中，政府、企业、城镇居民面临着同一问题，即：在广大居民迫切需要改善住房条件的同时，商品住房售难度大、空置率高，房地产市场沉淀大量资金。本文针对以上述情况，以北京为例，从商品房价构成和居民购房能力的角度进行了分析，力求解决高房价与低收入的矛盾。     

试论房地产市场的过热与泡沫

近期房价过高已引起各个方面的关心和重视,由此引发了关于我国房地产市场是否存在过热和泡沫的问题的讨论,本文就此问题展开初步的讨论。文章从房地产市场的过热与泡沫问题的概念出发,在对我国房地产市场的“国房景气指数”、开发投资指标、商品房空置率指标和房价收入指标的基础上分析,我们可以得到我国房地产不存在房地产泡沫,但要警惕泡沫出现的结论。     

"商品房空置率国际警戒线"质疑

目前，对我国商品住宅的空置率有一种“超警戒线”观点，即我国住宅空置率达到26％以上，已经超过了10％～15％住宅空置率的国际警戒线。本文从国内和国外考证了这种理论的产生及发展，指出了其存在的缺陷，并将这种理论得出的我国几个代表城市的空置率进行了分析，提出了并不存在符合各国实际的、统一的“商品房空置率国际警戒线”。     

北京市东部地区高档公寓租金与空置率相关性研究

本文以北京朝阳区高档公寓租赁市场为研究对象,构建经济模型,分析租金与空置率的内在关系,从而探寻租赁市场的运行规律,为促进租赁市场的良性发展提供参考建议。．研究以北京东部地区2000年第四季度至2010年第三季度的高档公寓实际租金与空置率为数据基础,通过构建两步骤的租金调整方程（two-equation model of rental adjustments）定量分析租金、空置率、自然空置率之间的动态变化。结果表明,北京市朝阳区高档公寓的空置率与其租金之间未表现出显著的正相关,但二者均受到通货膨胀的影响。     

Deconstructing distressed-property spillovers: The effects of vacant,tax-delinquent,and foreclosed properties in housing submarkets

In this empirical analysis, we estimate the impacts of property-tax delinquency, vacancy, and foreclosures on the value of neighboring homes. We demonstrate that these externalities differ in high- and low-poverty submarkets. Numerous studies have estimated the externality of foreclosures. These papers theorize that the foreclosure impact works partially through creating vacant and neglected homes. To our knowledge, this is only the second attempt to estimate the impact of vacancy itself and the first to use tax-delinquency as a measure of property neglect. We link vacancy observations from Postal Service data with property-tax delinquency and sales data from Cuyahoga County, Ohio. We find that an additional property within 500 ft that is vacant or delinquent reduces a home’s selling price by 1 to 2%. In low-poverty submarkets, the negative impact of a home that is both vacant and delinquent is ?4.6%. Low-poverty submarkets penalize a sale near a tax-current recent foreclosure by 4 to 8%. In high-poverty submarkets, we observe positive correlations of sale prices with vacant foreclosures. This may reflect lenders selectively foreclosing only on relatively well-maintained properties.
