Are stock and real estate markets integrated? An empirical study of six Asian economies

Rising asset prices spurred by Asia's emerging economy have drawn much attention recently. This study examines one source of growth patterns in asset prices by analyzing the integration relationship between stock markets and real estate markets in Asia. Six economies are selected for empirical analysis: China, Hong Kong, Japan, Singapore, South Korea, and Taiwan. Results show that stock markets are integrated with real estate markets in Japan, and partially integrated with real estate markets in China, Hong Kong, and Taiwan. This implies that these two investment vehicles are substitutable in China, Hong Kong, Japan, and Taiwan, and provide diversification potential for investment portfolios in South Korea and Singapore. Examining the timing of market changes, we found the real estate market leading the stock market in some countries, and the stock market leading the real estate market in others. We conclude that stock and real estate markets show a variety of inter-relationships depending on economic and political policy environments.     

产业集聚对中国房地产价格影响的实证研究

中国房地产价格持续上涨的成因一直是学界研究的热点。产业集聚作为市场经济活动的必然现象,是否会对房地产价格产生影响?以中国35个大中城市2000~2016年的数据为样本,构建静态面板模型和动态面板模型实证检验产业集聚对房地产价格的影响。研究表明,产业集聚对房地产价格具有显著的正向影响;进一步研究发现,人口集聚和土地成本是产业集聚影响房地产价格的重要中介,即产业集聚能够通过人口集聚和土地价格上涨来推动房价上涨。基于研究结论,为保证我国房地产市场健康发展,应采取促进区域均衡协调发展、多渠道保障城市新流入人口住房和加快土地市场改革等政策措施。     

住房耐用品、土地市场分割与货币失踪之谜

2008年国际金融危机后,我国M2供给增幅远高于CPI上涨幅度,这一现象被学界称为“货币失踪之谜”。本文构建了一个两部门新凯恩斯货币模型来研究这一问题。当外部需求下降后,央行降低利率以提振经济,房地产部门和非房地产部门同时扩张。由于住房属于耐用消费品,具有一定的金融属性,其需求对利率变化更敏感。利率下降后,住房需求相对普通消费品需求上升更多。因为存在土地市场分割,商住用地供给弹性较小,住房需求上升导致商住用地价格上升较多,地价上涨提升了房地产企业的抵押融资能力,房地产部门进一步扩张。普通消费品需求对利率反应小,需求较弱导致工业用地价格上升幅度较小,非房地产部门抵押融资能力小幅提升。因此,非房地产部门产出和CPI只温和扩张。Ramsey最优货币政策模拟表明,只有实现了房地产部门与非房地产部门均衡发展,才能实现社会福利最大化。     

Real estate auctions: A survey of theory and practice

Recent downturns in real estate markets combined with a general acceptance of auctions have resulted in an unprecedented number of auction sales. A need therefore exists for the further development of real estate auction models that can provide insights into this emerging market institution. To facilitate this task a survey of auction theory as pertaining to its application in real estate markets is provided in this paper. Topics addressed includes bidding equilibria, the role of reserve prices, information disclosure, the decision to use auctions, bidder participation, and multiple-object sales. An overview of empirical studies in this area is also provided.     

中国房地产市场价格泡沫与空间传染效应

本文使用对数周期性幂律(Log Period Power Law, LPPL)模型对房地产市场价格泡沫进行测度,运用空间计量模型对我国房地产市场价格泡沫和空间传染效应进行研究。LPPL模型认为由价格泡沫产生并最终破裂的金融市场与地震系统具有很多相似之处,即金融资产的价格呈周期性变化规律,价格持续上涨到临界状态直至反转。本文采用2010年6月至2017年11月间我国100个城市的房地产市场数据对各城市房地产价格泡沫进行测度和物理/经济空间传染效应研究。研究发现,LPPL模型能够对我国100个城市房地产价格泡沫进行甄别且主要存在两种泡沫状态:正向泡沫(房价持续上升)和反转泡沫(房价整体下降却存在反转点)。各个城市(地区)房地产价格具有较强的空间传染性;存在正向泡沫区域的空间传染性相较反转泡沫区域更为明显,在考虑经济空间测度而不是物理空间测度的情况下,各城市间的空间传染性更强。与现有文献不同,我们发现反转泡沫区域的新房价格指数特别是二手房价格指数的上升对周边城市的房地产价格指数存在强烈的正向推高影响。最后,本文发现城市的房地产调控政策在一定程度上抑制了房价传统影响(比如信贷、新房、二手房价等)因素的推高影响,但各城市房地产价格之间的联动变化特征应该引起监管部门的注意。     

Optimal Portfolio Choices, House Risk Hedging and the Pricing of Forward House Transactions

This paper develops a utility indifference model for evaluating various prices associated with forward transactions in the housing market, based on the equivalent principle of expected wealth utility derived from the forward and spot real estate markets. Our model results show that forward transactions in the housing market are probably not due to house sellers?? and buyers?? heterogeneity, but to their demand for hedging against house price risk. When the imperfections of real estate markets and the risk preferences of market participants are taken into consideration, we are able to show that the idiosyncratic risk premium, which mainly depends on the participants?? risk preferences and the correlation between the traded asset and the real estate, is a remarkable determinant of house sellers?? and buyers?? forward reservation prices. In addition, we also find that the market clearing forward price usually will not converge toward the expected risk-neutral forward price. The sellers?? or buyers?? risk aversion degrees and market powers are also identified to play crucial roles in determining the clearing forward price.     

租购并举、货币政策与房地产市场波动

为补足房地产市场发展短板,有效解决房地产市场结构性失衡,我国提出加快建立租购并举的住房制度,健全住房租赁市场,满足居民居住需求。本文通过构建一般均衡模型,分析住房租赁市场发展对宏观经济的影响,并采用1998~2010年全国30个大中城市季度数据分析在房地产市场化改革前期房地产市场结构失衡对宏观经济的影响,采用2002~2019年全国月度数据分析实施租购并举住房制度后房地产市场结构改善情况下,宏观经济变化以及货币政策对房地产市场的调节效应。研究结果表明:第一,房地产市场化改革前期,住房以"居住"属性为主,"投资"属性相对较弱;第二,租购并举制度下房租房价之间"剪刀差"的缩小能够有效改善房地产市场失衡的状况;第三,货币政策对房地产市场具有显著影响,但不同的货币政策会产生截然相反的作用。     

房地产价格地区差异影响因素的计量分析

伴随房地产市场调控政策的陆续出台,各地房地产市场的走势成为政府、产业界和消费者共同关注的焦点。国家要求各地要根据自身房地产市场的状况制定有针对性的限购政策和廉租房、经适房建设政策。这其中值得注意的一个重要问题就是各地政府如何根据房地产市场价格形成的内在规律,制定差异化的符合各地房地产市场发展实际的政策,从而对保证各地房地产市场的发展和民生的改善具有很好的协调性。因此,揭示房地产市场价格地区差异形成的内在机理,并以此作为制定各地差异化调控政策的依据,就成为其中的关键所在。     

Risk and return in residential spatial markets: An empiric and theoretic model

The paper is concerned with price and rent fluctuations in predominantly owner-occupied residental real estate. It presents the owner-occupier household as a housing consumer as well as an investor. It conjectures that since risk and return are known to be positively related in financial markets, they might also be thus related in residential real estate markets. If that is so, neighborhoods that are known to yield high returns will be the ones less price and rent stable than low yielding ones.The Capital Asset Pricing Model is not helpful in explaining a possible risk/return relationship in housing markets. Its major assumption about portfolio diversification is contrary to the nature of owner-occupied residential real estate. An owner occupier household, by definition, holds one unit of the asset and acts simultaneously as an investor and consumer of housing. For the capital market investor, investment and consumption decisions are separable. Therefore, a new theoretical model of consumer choice is proposed. Tel-Aviv price and rent data during a volatile market period are used for testing the main risk/return conjecture as well as other related hypotheses stemming from the model. The findings lend support to the conjecture and shed light on possible spatial determinants of owners' risk.     

限购政策是否降低了上市房地产企业价值？——基于强度双重差分法的经验研究

完善住房市场体系是国民经济中的重要议题,限购政策作为政府稳定和调节房地产市场的主要手段,对房地产企业以及住房市场体系建设均有重要影响。本文利用上市房地产企业2008—2013年以及2015—2019年的相关数据,通过构建强度双重差分模型实证分析了两轮限购对上市房地产企业价值的影响及其作用路径。实证结果表明:第一,两轮限购政策均显著降低了上市房地产企业市场价值,当企业在限购城市销售占比越大时,价值下降幅度越大;第二,从企业经营绩效来看,两轮限购对其实际盈利和营运能力并未产生显著影响,第一轮提高了企业偿债的经营风险,而第二轮只是影响了企业的资产增长能力;第三,两轮限购对房地产市场产生异质性影响,第一轮并未显著影响房价上涨,而第二轮则显著遏制了房价上涨;第四,从股票市场看,第一轮限购主要是通过企业经营风险影响投资者预期,而第二轮限购则是通过影响房价来改变投资者预期,这进一步凸显了“房住不炒”的政策作用。本文的研究意义主要体现在制定与推进政策时应关注预期的作用,这对于当前“房住不炒”政策的长期实施及其政策效果的长期稳定都具有一定启示。     

非线性视角下的中国房地产财富效应的测度研究——基于1996～2008年省际面板数据的分析

基于Hansen面板门槛模型,利用中国1996～2008年间30个省（市、区）的相关数据,进行了房地产财富效应的非线性检验。研究发现,从房价增长率和收入增长率来看,房价上涨对消费的影响存在着显著的单门槛效应,呈现非线性的区制变化,尽管总体上房价上涨不利于促进消费,但是在不同类型的区制,对消费的抑制程度存在着明显的差异。建议针对中国不同类型的区域,平抑房价的方式应有所区别,以减少可能出现的市场风险。     

基于房地产市场的我国系统性金融风险测度与预警研究

本文阐释了基于房地产市场的系统性金融风险形成机制,据此建立了分阶段、跨部门的房地产市场的系统性金融风险网络模型,并运用2006-2017年16家上市银行数据,分析和测度了我国房价大幅下跌所引发的系统性金融风险水平和结构,构建了基于房地产市场的系统性金融风险预警指标并进行测算。研究发现:在房价下跌30%的压力情景下,我国金融体系的潜在总损失总体呈级数式上升,年均增长22.70%;基于房地产市场的系统性金融风险值(SR)呈现先上升后波动下降的总体趋势;系统性金融风险(SR)的脆弱性指标(FLI)整体呈现波浪式振荡变化,且与房地产贷款/权益整体呈反向变动,系统性金融风险(SR)的传染性指标(CTI)在2012-2017年呈持续下降趋势,且与金融市场压力指数、金融机构间资产占总资产比重呈现出高度的一致性变化趋势。最后,基于房地产市场的系统性金融风险预警指标(SRWI)值呈收敛式振荡走势,表明基于房地产市场的系统性金融风险总体可控且呈收敛式下降。     

Transaction Volume and Price Dispersion in the Presale and Spot Real Estate Markets

Noise trading has been intensively studied in finance, but rarely in real estate. Theories of price dispersion have also been well established in retailing research, but less so in real estate. This paper is the first attempt to study the effect of noise trading on price dispersion in the real estate spot and presale (forward) markets. Quality-controlled price dispersion data series are estimated using a sample of transaction data in the housing presale and spot markets in Hong Kong. Our results show that transaction volume has a negative and significant effect on price dispersion in the spot market, but a positive and significant effect in the presale market. These support our conjecture that there are more noise traders in the presale market due to lower transaction costs. The volume effects also provide support for the use of a volume weighted least squares model when constructing a repeat sales index.     

The Asymmetric Wealth Effect in the US Housing and Stock Markets: Evidence from the Threshold Cointegration Model

Previous studies commonly use a linear framework to investigate the long-run equilibrium relationship between the housing and stock markets. The linear approaches may not be appropriate if adjustments from disequilibrium are asymmetric in both markets. Nonlinear adjustments are likely to be observed since the two markets respond rather differently to negative shocks where the stock market is more volatile but price rigidity is found in the housing market. In this paper, we firstly propose two hypotheses on the long-run equilibrium relationship of the US housing and stock markets, and then employ the threshold cointegration model to investigate the potential asymmetric relationships between the two markets. Our empirical results reveal that cointegration exists among the markets, but adjustments toward its long-run equilibrium are asymmetric. Further evidence points out that a rapid mean reversion occurs in one regime where the stock price outperforms the housing price, and no significant reversion is found in the other regime, supporting the hypothesis of the existence of an asymmetric wealth effect among the two markets in the US. Furthermore, evidence from the asymmetric vector error correction model shows that significant error corrections toward the equilibrium exist in the short run only when the stock price exceeds the real estate price by the estimated threshold level, reassuring the finding of the asymmetric wealth effect.     

偏低定价、贷款放宽与房地产价格——基于PW模型的中美比较及启示

Pavlov and Wachter(2004,2006)从市场竞争的角度发现住房信贷偏低定价是推动信贷过度扩张从而导致房地产价格膨胀的一个重要原因。本文认为流动性过剩将加剧这种现象,同时贷款放宽也是推动信贷过度扩张导致房地产价格上涨的重要原因。近年来在流动性过剩下中美两国住房信贷市场都出现了偏低定价和贷款放宽现象,其表现和产生的原因具有共性和个性。在中美比较的基础上,本文提出了对我国的几点启示。

Are REITs real estate? Evidence from international sector level data

The aim of this study is to examine whether securitized real estate returns reflect direct real estate returns or general stock market returns using international data for the U.S., U.K., and Australia. In contrast to previous research, which has generally relied on overall real estate market indices and neglected the potential long-term dynamics, our econometric evaluation is based on sector level data and caters for both the short-term and long-term dynamics of the assets as well as for the lack of leverage in the direct real estate indices. In addition to the real estate and stock market indices, the analysis includes a number of fundamental variables that are expected to influence real estate and stock returns significantly. We estimate vector error-correction models and investigate the forecast error variance decompositions and impulse responses of the assets. Both the variance decompositions and impulse responses suggest that the long-run REIT market performance is much more closely related to the direct real estate market than to the general stock market. Consequently, REITs and direct real estate should be relatively good substitutes in a long-horizon investment portfolio. The results are of relevance regarding the relationship between public and private markets in general, as the ‘duality’ of the real estate markets offers an opportunity to test whether and how closely securitized asset returns reflect the performance of underlying private assets. The study also includes implications concerning the recent financial crisis.     

Momentum in Residential Real Estate

This paper examines whether there is return momentum in residential real estate in the U.S. Case and Shiller (American economic review 79(1):128–137, 1989) document evidence of positive return correlation in four U.S. cities. Similar to Jegadeesh and Titman’s (Journal of finance 56:699–720, 1993) stock market momentum paper, we construct long-short zero cost investment portfolios from more than 380 metropolitan areas based on their lagged returns. Our results show that momentum of returns in the U.S. residential housing is statistically significant and economically meaningful during our 1983 to 2008 sample period. On average, zero cost investment portfolios that buy past winning housing markets and short sell past losing markets earn up to 8.92% annually. Our results are robust to different sub-periods and more pronounced in the Northeast and West regions. While zero cost portfolios of residential real estate indices is not a tradable strategy, the implications of our results can be useful for builders, potential home owners, mortgage originators and traders of real estate options.     

Asset Bubbles: an Application to Residential Real Estate

Behavioural models offer new insights into why bubbles are ubiquitous in residential real estate markets. These markets are dominated by unsophisticated households who often develop optimistic views by extrapolating from past returns. Rational investors cannot easily trade against an overvaluation of housing assets because of high transaction costs and a binding short sale constraint. Circumventing the effect of the latter, the supply of housing frequently increases in response to rising prices. This helps to mitigate bubbles but often leads to overbuilding, which slows down the recovery after a bubble bursts. Models that incorporate the effects of perverse incentives and limits to arbitrage are especially helpful in explaining the bubble that developed in mortgage‐backed securities and helped fuel the recent real estate bubble by relaxing home buyers’ borrowing constraints. The literature is ambiguous about whether governments should intervene to burst bubbles, as a better response may lie in improving incentives of key market players.
