A robust house price index using sparse and frugal data

In this article, we describe a house price index algorithm which requires only sparse and frugal data, namely house location, date of sale and sale price, as input data. We aim to show that our algorithm is as effective for predicting price changes as more complex models which require detailed or extensive data. Although various methods are employed for determining house price indexes, such as hedonic regression, mix-adjusted median or repeat sales, there is no consensus on how to determine the robustness of an index, and hence no agreement on which method is the best to use. We formalise an objective criterion for what a house price index should achieve, namely consistency between time periods. Using this criterion, we investigate whether it is possible to achieve strong robustness using frugal data covering only 66 months of transactions on the Irish property market. We develop a simple multi-stage algorithm and show that it is more robust than the complex hedonic regression model currently employed by the Irish Central Statistics Office.     

房产税试点立法与税收立法权的法律规制

上海、重庆两地房产税试点立法引起业界对地方房产税收立法权的合法性质疑。本文从地方税收立法权的法律界定入手,深入分析探讨此次试点立法之所以引起合法性质疑的制度性原因,进而提出遵守税收法定主义、明确税收立法权的法律界定、限制地方税收立法权等完善制度的建议和看法。     

土地政策在房地产调控中的政策效果评价

自2003年以来,土地政策被确定为与传统的货币政策、财政政策并列的重要工具参与宏观调控,但土地政策在房地产调控中的成效一直备受争议.本文利用国家统计局、中国经济信息网2002～2010年间的季度数据,实证分析了土地政策及其不同手段对房地产市场的影响,认为土地政策只对房地产供应方面的作用较为显著,且存在滞后性,而对房价的作用较小,因此,土地政策整体上在房地产调控中的作用有限,需要与其他政策组合起来进行运用.

限购令法律问题探究

2010年,房地产限购令出台以后对市场交易造成了极大影响。本文认为限购令从性质上看主要是属于一种经济政策,它的内容已经构成了对《物权法》和《价格法》等法律制度的违背。另外,限购令作为一种抽象行政行为违反了行政法的比例原则,也过度干预了市场主体的自主交易行为,有必要将限购令纳入司法审查范围,加强对相关责任主体的规制。

奥地利发展低碳节能建筑的历程及关键技术

本文对奥地利近10年来发展节能建筑的情况和并对目前已经出现的几种节能建筑和关键技术进行了介绍。早在1999年，奥地利联邦政府就推出了一项“未来建筑计划”，在全国范围内大规模地启动了建筑节能运动，积极推行节能建筑设计技术、地源热泵技术、光伏利用技术、自控通风系统等，采用新型保温建筑材料和新体门窗。     

Testing for rational bubbles in the US housing market

The presence of a bubble in the US housing market prior to the 2007 subprime mortgage financial crisis is investigated. This is done by looking into the relationship between house prices and rental prices, known as the price–rent ratio, which is an important measure of a potential deviation between house prices and its fundamental value. Additionally, the interest rate is taken into account since it is an important factor in determining demand for housing mortgages and thereby influencing house prices, and explosive behavior of house prices is considered. These relationships are investigated through a theoretical and econometrical framework. The empirical evidence suggests that there was a bubble in the housing market prior to the financial crisis, even when controlling for the decreasing interest rate and the fundamental information given by the rental price in the period. Explosiveness was the main source of the price increase, such that a bubble was present in the housing market after correcting for other fundamental factors. The econometric procedures used in the analysis may therefore be relevant for monitoring the housing market.     

基于房价收入比的梯度住房政策体系研究——以上海市为例

为了实现"居者有其屋",需要针对不同的收入群体采取不同的住房政策,为此要对居民的住房支付能力进行科学的判断。本文采用国际通用的衡量居民住房支付能力的"房价收入比"指标,用上海市的实际数据对其进行修正使用,以计算结果作为制定差别化住房政策的标准,建立起长效、稳定的住房经济调控政策与住房社会保障政策相结合的梯度住房政策体系。
