我国房价的货币因素与宏观影响的动态传导研究——基于TVP-SV-VAR模型的分析

我国房地产和金融市场发展使房价进入到货币政策传导渠道中,房价与货币政策中介变量、宏观目标变量间的关系呈动态变动。本文通过TVP-SV-VAR模型研究发现:与M2和信贷相比,社会融资规模与房价的关系更稳定,且对彼此波动的反应更强;近些年房价波动对产出、物价波动的边际效应减弱,对金融稳定的影响仍较大,房价对外部因素波动的敏感性有所降低。建议国家应坚持稳定房价的总基调,把好货币供给闸门,合理管控社会融资规模增量,加强房地产各项融资监管;各地方政府应根据本地人口流入和住房库存等实际情况,合理推进房地产业发展,在发挥其积极作用的同时,防范区域金融风险。     

房价调控、地方政府债务与宏观经济波动

在地方政府债务高企的背景下,房价调控能否使资本流向非房地产部门？房价调控如果触发地方政府债务违约,宏观政策应如何应对？本文基于中国宏观经济的特征事实,引入地方政府的土地财政行为,将房价变动与地方政府的偿债能力联系起来。研究表明,由于地方政府依赖土地出让和土地抵押贷款筹集收入,房价管控导致的地价下降会带来地方政府收入的下降,直接影响地方政府的偿债能力。如果地方政府债务不出现违约,那么房价管控带来的地价下降会降低地方政府从金融部门获得的抵押融资额,使非基建部门的融资成本下降,非基建部门投资和产出上升。而如果调控房价带来的地价下降导致地方政府出现债务违约,金融部门资产受损,使金融中介减少贷款和提高贷款成本,带来整个社会的信贷紧缩,经济中各个部门的产出大幅下降。进一步的政策分析表明,有必要在避免地方政府债务违约的同时,使用财政资金补充银行资本金等多种方式稳定金融中介的资产负债表,从而将房价调控对经济的负面影响程度降到最低。     

收入差距、信贷约束与房价变动

本文通过构建一个异质性代理人模型,刻画了收入差距通过信贷渠道影响房价的作用机制。研究表明,收入差距的缩小提升了低收入者的收入占比,使该类人群获得了更多的外部融资进行购房,由此产生了两方面效应:(1)信贷约束放松降低了住房流动性溢价,从而对房价产生负向影响;(2)收入上涨增加了住房边际效用较高的低收入者对房价正向影响的权重,从而使住房需求上升的效应抵消了此前的负向影响,最终促进房价上涨。通过对1970-2017年44个国家的进一步分析发现,相比于高收入者收入的下降,低收入者收入占比的上升在放松信贷约束和提升房价方面具有更显著的作用。据此本文认为:一方面要通过增加住房供给来化解城市化率提升与高房价之间的内在矛盾;另一方面,在经济增速放缓的时期,缩小收入差距,推动以“人”为核心的高质量城市化,并引导信贷资源向低收入群体倾斜是当前促进国内大循环、稳定社会融资规模和房地产市场的重要手段。     

The Dynamics of Location in Home Price

It is well established that house prices are dynamic. It is also axiomatic that location influences such selling prices, motivating our objective of incorporating spatial information in explaining the evolution of house prices over time. In this paper, we propose a rich class of spatio-temporal models under which each property is point referenced and its associated selling price modeled through a collection of temporally indexed spatial processes. Such modeling includes and extends all house price index models currently in the literature, and furthermore permits distinction between the effects of time and location. We study single family residential sales in two distinct submarkets of a metropolitan area and further categorize the data into single- and multiple-transaction observations. We find the spatial component is very important in explaining house price. Moreover, the relative homogeneity of homes within the submarket and the frequency with which homes sell affects the pattern of variation across space and time. Differences between single and repeat sale data are evident. The methodology is applicable to more general capital asset pricing when location is anticipated to be influential.     

Renegade Asset Markets

Local markets with tight land use controls result in prices rising relative to wages and affordability. Affordability is eased by unconventional but risky finance. Tight land use and loose financing in these renegade markets concentrates the impact of national or international shocks. A positive demand shock raises prices in these tight markets. If ongoing price momentum is expected, households switch to ownership and landlords reduce the rental stock. House prices, rents and occupancy rise and fall together in these markets. A five-equation sequential structure in land use, financial contracts, house prices, rents and vacancy for 17 United States cities confirms geographical concentration. Coastal California and South Florida are fundamentally risky markets. Discount rates there are three percentage points higher than the sample median. Two percentage points are attributable to land use and the other to unconventional finance. National and international financial crises are highly concentrated regionally.     

How do house prices affect consumption? Evidence from micro data

Housing is a major component of wealth. Since house prices fluctuate considerably over time, it is important to understand how these fluctuations affect households’ consumption decisions. Rising house prices may stimulate consumption by increasing households’ perceived wealth, or by relaxing borrowing constraints. This paper investigates the response of household consumption to house prices using UK micro data. We estimate the largest effect of house prices on consumption for older homeowners, and the smallest effect, insignificantly different from zero, for younger renters. This finding is consistent with heterogeneity in the wealth effect across these groups. In addition, we find that regional house prices affect regional consumption growth. Predictable changes in house prices are correlated with predictable changes in consumption, particularly for households that are more likely to be borrowing constrained, but this effect is driven by national rather than regional house prices and is important for renters as well as homeowners, suggesting that UK house prices are correlated with aggregate financial market conditions.     

Retracted: Risk Management in Financial Institutions

We study risk management in financial institutions using data on hedging of interest rate and foreign exchange risk. We find strong evidence that institutions with higher net worth hedge more, controlling for risk exposures, across institutions and within institutions over time. For identification, we exploit net worth shocks resulting from loan losses due to declines in house prices. Institutions that sustain such shocks reduce hedging significantly relative to otherwise-similar institutions. The reduction in hedging is differentially larger among institutions with high real estate exposure. The evidence is consistent with the theory that financial constraints impede both financing and hedging.     

高房价是否导致了区域高技能人力资本流出?

我国正处于由人口大国向人力资本强国转型的关键阶段,高技能人才资源已成为当今区域经济社会发展的第一资源;与此同时,我国已经历了一段房价全面上涨的时期,由房价高速上涨所导致的人才流出问题引起政府与公众的广泛关注。在此背景下,本文通过对大学生就业地选择的关注,考察了高房价对地区高技能人力资本流出的影响。本文的结果稳健地表明,高房价显著地提高了大学毕业生离开本地就业的概率;根据本文的估计,在2010年至2015年期间,房价的上升至少增加了区域高技能人才流出21.5%;特别地,房价的挤出作用对于较弱家庭背景的学生以及非一线城市更为严重,此外,高房价也影响了大学毕业生的职业选择。本文的研究结果指出了中国高房价可能影响长期经济社会发展的一个新的重要渠道;同时,通过对房价的关注,为地区与国家减少高技能人才流出,实现经济发展由要素驱动向创新驱动转变提供了新的启示。     

House prices,consumption and the role of non-Mortgage debt

This paper evaluates the strength of the relationship between house prices and consumption, through the use of debt. Whereas the existing literature has largely studied the effects of house prices on homeowner total or mortgage debt, we focus on the non-mortgage component of household borrowing, using Canadian household-level data for 1999–2007. We rely on variation in regional house prices, homeownership status and age to establish the relationship between house prices and non-mortgage debt. Then, using direct information on debt uses, we determine that house price growth was associated with a non-trivial fraction of concurrent aggregate non-housing consumption growth.     

The role of liquidity constraints in the response of monetary policy to house prices

We analyse the optimal response of monetary policy to house prices in a New Keynesian framework. A positive wealth effect from housing is derived from liquidity constrained consumers. Housing equity withdrawal allows them to convert an increase in housing value into consumption and we show that monetary policy should react to house prices due to their effect on consumption by constrained agents. Moreover, we allow the share of liquidity constrained consumers to vary with house prices. Consequently, the optimal weights on expected inflation, the output gap and house prices in the optimal interest rate rule vary over time too.     

The Housing Market in the United Kingdom: Effects of House Price Volatility on Households

This paper describes the economics of the housing market and explains why house prices are likely to be more volatile than prices in other markets. It illustrates the volatility of house prices relative to some other key economic variables in the UK. The paper then considers the implications of variability in house prices for household behaviour, surveying a number of studies for the UK and elsewhere on the effects of house price volatility on consumption spending, indebtedness, labour supply, and entry to and exit from the homeownership market.     

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.     

Correlated leverage and its ramifications

This paper develops a theory in which housing prices, the capital structures of banks (mortgage lenders) and the capital structures of mortgage borrowers are all endogenously determined in equilibrium. There are four main results. First, leverage is a “positively correlated” phenomenon in that high leverage among borrowers is positively correlated with high leverage among banks, and higher house prices lead to higher leverage for both. The intuition is that first-time homebuyers with fixed wealth endowments must borrow more to buy more expensive homes, whereas higher current house prices rationally imply higher expected future house prices and therefore higher collateral values on bank loans, inducing banks to be more highly levered. Second, higher bank leverage leads to greater house price volatility in response to shocks to fundamental house values. Third, a bank’s exposure to credit risk depends not only on its own leverage but also on the leverage decisions of other banks. Fourth, positive fundamental shocks to house prices dilute financial intermediation by reducing banks’ pre-lending screening, and this reduction in bank screening further increases house prices. Empirical and policy implications of the analysis are drawn out, and empirical evidence is provided for the first two main results. The key policy implications are that greater geographic diversification by banks, tying mortgage tax exemptions to the duration of home ownership, and increasing bank capital requirements when borrower leverage is high can help reduce house price volatility.     

Predicting House Prices Using Multiple Listings Data

It is often necessary to accurately predict the price of a house between sales. One method of predicting house values is to use data on the characteristics of the area's housing stock to estimate a hedonic regression, using ordinary least squares (OLS) as the statistical technique. The coefficients of this regression are then used to produce the predicted house prices. However, this procedure ignores a potentially large source of information regarding house prices—the correlations existing between the prices of neighboring houses. The purpose of this article is to show how these correlations can be incorporated when estimating regression coefficients and when predicting house prices. The practical difficulties inherent in using a technique called kriging to predict house prices are discussed. The article concludes with an example of the procedure using multiple listings data from Baltimore.     

Do Capital Flows Matter to Stock and House Prices? Evidence from China

This article analyzes the impacts of foreign direct investment (FDI) and short-term capital flows, otherwise known as hot money, on stock and house prices in China. Empirical results, estimated using the local projections approach, reveal that a positive hot money net inflow shock significantly increases stock and house prices and the impacts persist for up to 1–2 months, while a positive FDI net inflow shock contributes significantly to lagged house price appreciation but has no effect on stock prices. This study also identifies negative pass-through effects of FDI net inflows on hot money net inflows and positive pass-through effects of stock prices on house prices.     

The Dynamic Relationship Between Housing Prices and the Macroeconomy: Evidence from OECD Countries

This paper studies the dynamic relationship among house prices, income and interest rates in 15 OECD countries. We find that any disequilibrium in the long-run cointegrating relationship among these variables is corrected by the subsequent movement in house prices in most of these countries. This error-correction property of house prices implies that most of the variations in house prices are transitory, as compared to the movements in income and interest rates that are permanent, suggesting that the short-run movements in house prices are independent of the movements in income and interest rates. The results suggest that only the permanent movement in house prices, income and interest rates are associated with each other. We also find that the correlation in house price cycles across different OECD countries has changed over time with the highest correlation during the boom period of 1998–2005.     

住房价格、金融稳定与宏观审慎政策

本文通过建立包含异质性家庭、异质性厂商和金融机构的DSGE模型,分析对预期房价作出反应的货币政策和宏观审慎政策的传导机制和政策效果,研究不同政策的选择和协调问题。研究发现,首先,由于政策的作用范围不同,不同政策会对金融稳定和经济稳定产生不同影响。对预期房价作出反应的货币政策能够抑制住房需求和信贷供给,但也会抑制消费需求和产出;而对预期房价作出反应的逆周期LTV政策和逆周期资本充足率政策在应对房价波动导致的金融稳定问题时更加有的放矢。其次,外生冲击的来源会影响政策的选择和协调——当经济波动来源于需求冲击时,固定LTV政策搭配逆周期资本充足率的宏观审慎政策、不对预期房价作出反应的货币政策表现最优;当经济波动来源于供给冲击时,固定LTV政策搭配逆周期资本充足率的宏观审慎政策、对预期房价作出反应的货币政策表现最优。     

The role of house prices in the monetary policy transmission mechanism in small open economies

We analyse the role of house prices in the monetary policy transmission mechanism in Norway, Sweden and the UK, using structural VARs. A solution is proposed to the endogeneity problem of identifying shocks to interest rates and house prices by using a combination of short-run and long-run (neutrality) restrictions. By allowing the interest rate and house prices to react simultaneously to news, we find the role of house prices in the monetary transmission mechanism to increase considerably. In particular, house prices react immediately and strongly to a monetary policy shock. Furthermore, the fall in house prices enhances the negative response in output and consumer price inflation that has traditionally been found in the conventional literature. Moreover, we find that the interest rate responds systematically to a change in house prices. However, the strength and timing of response varies between the countries, suggesting that housing may play a different role in the monetary policy setting.     

House Prices and Government Spending Shocks

We show that dynamic stochastic general equilibrium (DSGE) models with housing and collateralized borrowing predict a fall in house prices following positive government spending shocks. By contrast, we show that house prices in the United States rise persistently after identified positive government spending shocks. We clarify that the incorrect house price response is due to a general property of DSGE models—approximately constant shadow value of housing—and that modifying preferences and production structure cannot help in obtaining the correct house price response. Properly accounting for the empirical evidence on government spending shocks and house prices using a DSGE model therefore remains a significant challenge.     

住房价格、房屋购买与中国家庭杠杆率

本文基于中国家庭追踪调查的微观数据以及相匹配的城市层面的住房价格数据,从住房购买需求的角度,给出了一个近年来家庭杠杆率急剧上升的解释。利用中国家庭追踪调查的微观数据探讨了房价上涨对家庭杠杆率的作用机制以及潜在影响。结果表明,住房价格的快速上涨推动了家庭杠杆率的急剧攀升,从数量上看,房价每上涨1倍,样本期间的家庭贷款数额将会增长288.1%,家庭杠杆率将上升39.2%,而此部分贷款的增加主要来源于银行贷款而非私人借贷,由房价导致的家庭借贷数额和杠杆率的上升大概占到购房家庭总体借贷数额和杠杆率上升的90%左右。机制分析表明,住房价格的快速上涨刺激了家庭必需型和投资型住房需求,并提高了家庭的借贷意愿和风险偏好。分样本的探讨发现,这一效应对于非农户口家户以及有配偶和子女家户的影响更为明显。
