对廉租公寓建设的思考

在我国城市化不断加快的背景下，以暂住人口为主体的城市过渡群体具有特殊的住房需求。由于城市住房供应结构尚不完善，过渡群体对过渡房的需求主要由城中村出租房和部分社会出租房提供。随着城中村改造的完成，过渡房需求将存在供给主体的缺失。因此，需要建立以福利性为主、部分微利性为辅的多层次、多类型的廉租公寓，通过政府主导，设立规划、建设、土地、财政等多部门联动协调的专职部门，进行多渠道筹集资金，结合城中村改造进行统筹规划、合理布局，并加强后期公共管理与服务工作。     

房地产新政对地方财税的影响和对策分析——以江苏南通市为例

近年来,国家对房地产市场采取了一系列宏观调控措施,长三角地区更是作为被调控的重点地区,身处其中的江苏省南通市房地产市场也受到一定影响,进而造成地方财税的增幅出现下降态势,今后应通过稳定住房价格、鼓励房地产交易和严格税费征管等对策在促进地区房地产市场健康发展的同时使地方财税得到持续增长。     

农村住房商品化改革：困境、前景与立法路径

农村住房商品化有利于发挥物尽其用的价值,有利于推进新农村的建设。然而,现阶段农村住房是不能作为商品流转的。文章分析了制约农村住房商品化的相关因素,如农用地的匮乏、城乡二元结构的存在、农业生产效率的低下、农宅交易规则的缺失等。在此基础上,文章探寻了农村住房商品化的可行性,进而提出了规范农宅流转的立法建议：明确农宅商品化改革应遵循的基本原则,清晰界定农宅的市场准入条件,明确农宅流转应遵循的交易规则,完善农宅流转收益的分配机制。     

A Bayesian Approach to the Construction and Comparison of Alternative House Price Indices

Several repeat-sales models have been advanced over the years for estimating real estate price indices. This article proposes a general model which incorporates earlier works as special cases and compares the alternative repeat-sales models using posterior odds ratios as criteria. While the existing literature estimates the real estate indices from the sampling point of view, in this article indices are constructed and then compared using a Bayesian approach. In general, the two-error term models outperform the one-error models. The model with a nontemporal component proposed by Goetzmann and Spiegel is found to be superior in three out of four cities. There is a significant discrepancy among the returns and indices obtained from different models.

Do brokerage houses add value? The market impact of UK sell-side analyst recommendation changes

This paper reports on the first full study investigating the economic role of sell-side analysts’ stock recommendations in the UK market. We also explore whether UK analysts are, in practice, influenced by the same biases as that reported for their US counterparts.We find that share prices are significantly influenced by analysts’ recommendation changes, not only at the time of the recommendation change but also in subsequent months. The price reaction to new sell recommendations is greater than the price reaction to new buy recommendations and exhibits post-recommendation drift which is consistent with initial underreaction to bad news. Returns generated are influenced, cross-sectionally, by factors associated with a firm's information environment and analyst incentives such as size, same-sign earnings forecast revisions and recommendation changes that skip a rank.We find that UK analysts’ investment recommendations in practice appear less susceptible to potential conflicts of interest than their US counterparts. The ratio of new sell to buy recommendations is higher in the UK and a greater proportion of such recommendations are accompanied by same-sign earnings forecast revisions than their equivalents in the US. We find brokerage house investment banking relationships do not appear to impact (adversely) on abnormal returns.     

Alternative Methods of Increasing the Precision of Weighted Repeat Sales House Prices Indices

Weighted repeat sales house price indices have become one of the primary indicators used to identify housing market conditions and to estimate the amount of equity homeowners have gained through house price appreciation. The primary reason for the acceptance of this methodology is that it derives a location specific (typically, census division, state or metropolitan area) average change in house prices from repeated observations of individual house prices. It is this repeat attribute that allows repeat sales price indices to claim that it is a preferable index which does a better job of holding quality constant. The amount of time between the two observed prices for a single property is determined by when the home transacts. Some homes transact twice in a period of months and others do not transact for decades. It is likely that individual house price appreciation rates vary from the mean appreciation rate, as estimated by the index, in a systematic fashion. In general, the longer the time between transactions the more variance there is in individual house price appreciation. This paper extends this concept to include new dimensions. For instance, houses that appreciate faster than the mean, as estimated by the index for that location, may experience a different variation structure than homes that appreciate slower. This process can be viewed as an asymmetric treatment of the variance of house price appreciation around the estimated index. In addition, the variance of expensive and affordable homes may also be different and time varying. This paper finds evidence that adding the dimensions of price tiers and asymmetry to the variance estimate has merit and does affect the estimated index as well as homeowner equity estimates. Homeowner equity estimates are especially sensitive to these added dimensions because they depend on both the revised index and the estimated variances, which are specific to each dimension considered—time between transaction, asymmetry, and price tier.
