贫富差距、供求弹性与房价*

近些年，中国的贫富差距和房价居高不下，但现有文献忽视供求弹性与贫富差距交互作用对房价的影响。据此，本文构建结合贫富差距和供求弹性的住房存量调整模型，使用中国2002—2012年7省份33个城市的UHS数据发现，收入和财富的基尼系数对房价有正影响；供求弹性对房价分别有负影响和正影响；收入和财富基尼系数与供求弹性交互项对房价分别有正影响和负影响。据此，为防止房价泡沫，各级政府一方面应缩小贫富差距，另一方面应增加土地和住房供给。     

媒体情绪与房价波动*

本文使用2000—2015年中国112个大中城市媒体报道和房价月度指数研究了媒体异质性对房价波动的影响。研究发现,纸媒情绪对房价波动的影响大于网媒情绪,中央媒体情绪对房价波动的影响大于地方媒体情绪,明星微博情绪对房价波动的影响大于普通微博情绪,媒体语气确定性和报道篇幅对房价波动有正影响,明星城市媒体情绪较非明星城市更易引起房价波动。据此,为防范非理性房价波动,应加强对不同媒体报道的监管。

THE IMPACT OF FINANCIAL HELP AND GIFTS ON HOUSING DEMAND AND COST BURDENS

Financial transfers are an important source of income for many households and recipients may use these funds to pay for housing services. This paper examines the separate impact of financial help and substantial gifts on both housing demand and housing cost burden. The results indicate receiving gifts has a positive and statistically significant impact on housing demand. Households receiving help or gifts have substantially higher housing cost burdens, all else being held constant. These findings have implications for the financial well-being of recipient households and ultimately, the mortgage industry . ( JEL R20, R21)     

COSTS OF HOUSING CRISES: INTERNATIONAL EVIDENCE

This paper analyses the costs of housing crises in terms of GDP growth and the economic conditions under which crises are particularly costly. Housing crises are often followed by recessions that are longer than other recessions. According to empirical estimates, a housing crisis reduces the GDP growth rate in the following year on average by two percentage points and has still a considerable negative impact in the second year. One important channel through which the effect of housing crises is passed on seems to be the banking sector. In addition, our results suggest that negative wealth effects possibly cause further reductions in GDP growth.     

A LANDFILL CLOSURE AND HOUSING VALUES

The United States disposes roughly 60% of the municipal solid waste it generates each year in solid waste disposal facilities, commonly known as landfills. Hedonic pricing studies have estimated the external costs of landfills on neighboring housing markets, but the literature is silent on what happens to property values after the landfill closes. Original housing price data collected both before and after a landfill closure are used to estimate how a landfill closure affects neighboring property values. Results of both a hedonic pricing model and a repeat-sales estimator are used in the analysis. ( JEL H42, H72, Q51, Q53, R21)     

分税制改革、财政分权和房价水平

1998年房改以来,中国城镇房价持续快速上涨,引起了社会公众的广泛关注。本文发现,较高的房价水平总是与较高的财政分权度联系在一起的,而较高的财政分权度又与1994年的分税制改革密切相关。本文采用2000-2008年的分省面板数据,研究分税制改革背景下财政分权度对房价的影响机制,为上述假说提供实证证据。结果表明,分税制背景下逐年扩大的财政分权度是导致房价持续过快上涨的不可忽视的制度性因素。在使用了不同的计量方法、识别技术以及控制了其他潜在影响房价的因素后,本文的估计结果依然是稳健的。     

高房价与城镇居民创业*——基于CHIP微观数据的实证分析

以往有关高房价与创业的研究存在一定争议,本文基于2002年和2008年中国家庭收入调查（CHIP）分析了高房价对城镇居民创业行为的影响。实证结果表明,在其他条件不变的情况下,高房价能够提高中国城镇居民的创业概率,负担房贷会降低城镇居民创业的可能性,高房价刺激的多为自雇型创业,对老板型创业的促进作用不明显。由于促进的大多是自雇型创业,所以不能高估高房价对创业活动的激励作用,在未来鼓励大众创业的过程中应该着重考虑其他制度性因素。       

DISINFLATION AND HOUSING INVESTMENT: A REVISIOIIIST ANALYSIS

The pattern of housing investment through the Seventies was a product of high and variable rates of inflation, a financing system that was segmented from other capital markets and restricted in scope, and a tax system that abetted the demand for housing relative to other investments. In the early Eighties, each of these elements changed. Financial reform brought the housing name system into tune with the rest of the financial sector, and tax cuts increased the demand for forms of investment other than housing. Most important, the rate of inflation slowed dramatically, falling below 4 percent in both 1982 and 1983. The result of all these occurrences was fairly predictable: A decline in the demand for housing as an investment. However, this declining demand has been offset by two factors. The first is the drop in nominal interest rates that accompanied declining inflation. This increased the "affordability" of homing. Second, large numbers of households entered prime home-buying years and spurred demand for housing as shelter. The current situation is a housing market driven more by consumption demand than by investment demand     

土地财政制度对房地产价格的影响因素研究*

本文基于动态系统GMM模型,运用Stata软件和计量经济学方法,对2009—2015年中国15个大中城市房价水平的变化趋势进行研究。结果表明：（1）地方政府依靠土地财政和房地产维持地方财政,土地财政是导致房价上涨的根本原因。（2）在经济下行的背景下,地方政府和房企共同经营土地,地方政府试图通过做大土地财政拉动地方经济。（3）中央政府选择有利于中央政府效用水平增加的经济发展方式。所以中央政府、地方政府与房企会形成经济增长联盟共同推动房价上涨。（4）房企行为对土地财政导致的高房价具有放大效应,且作用效果在东部、中西部地区呈现明显的区域差异。本文的贡献是发现了房企行为与土地财政、房价上涨之间相互作用的逻辑关系,为找到缓解房地产价格上涨的措施提供了新的可能性。     

利率效果区域异质性、收入跨区 影响与房价溢出效应*

本文首先构建了理论分析框架,解释了中国不同城市间房价溢出效应、收入对房价的跨区影响,以及利率调整对不同城市房价的区域异质性影响。本文利用GVAR模型对该框架进行了实证,结果显示北京等一线城市的房价波动对其他城市具有较大的溢出性,而中西部城市的房价溢出性则不明显。一线城市和东部城市的房价波动不仅受本城市人均收入变动的影响,还在很大程度上受其他城市收入变动的影响,而中西部城市的房价则主要受本城市收入变动的影响。利率变动对一线城市和东部城市的房价影响则较大,而对中西部城市的房价影响有限。本文结论具有明确的政策含义,比如政府应通过稳定一线城市房价以达到稳定全国房价的目的,促进公共产品均等化,实行地区差异化的房地产政策等。通过利率调整来调控房价也是一个可行的政策选项。     

租售比与中国城市住房泡沫*

本文在住房消费性和投资性需求基础上,通过泡沫和无泡沫租售比测度住房泡沫。本文对中国1996-2013年35个大中城市数据分析发现：第一,北京、上海等16个城市存在住房泡沫;第二,房价预期易催生东部和一线城市而非中西部和二三线城市住房泡沫;第三,利率政策对抑制中西部和二三线城市住房泡沫比东部和一线城市更有效;第四,住房存量过大引发住房泡沫;第五,房贷和开发成本助长住房泡沫;第六,土地财政助长住房泡沫,但股票市场回报率抑制住房泡沫。     

HOUSING POLICY FOR THE ELDERLY: A POLICY TO BUILD BARRIER‐FREE RENTAL HOUSING

There is a strong need for barrier‐free rental housing because of the rapidly aging population in Japan, where the share of barrier‐free rental housing is only 18.24% of total rental housing. We propose a policy to solve the problems associated with supplying barrier‐free rental housing. Our scheme involves a method of funding rental housing with a securities investor, as well as implementing property management and introducing rent subsidies. The plan entails funds being collected to construct barrier‐free rental housing. The housing will generate positive rental profits, which will, in turn, lead to the increase in the supply of barrier‐free rental housing. According to our plan, the low‐income elderly will also have access to barrier‐free rental housing.     

城市住宅用地空间扩张机制与调控对策

城市住宅用地空间扩张的必然性与土地资源的稀缺性这一对矛盾,在城市化进程迅速推进的今天显得尤为尖锐,如何实现城市居民居住质量的提高与城市土地资源的可持续利用成为迫切需要解决的问题。文章总结了我国当前城市住宅用地扩张的特点,从经济、制度、技术以及人为干预四个方面对我国当前城市住宅用地空间扩张机制进行了解析,并对城市住宅用地空间扩张过程所出现的问题提出了相关调控措施。     

ECONOMIC GROWTH AND INCREASING HOUSE PRICES

Abstract.  Several cities and countries in Asia and North America have experienced large increases in housing prices. We extend the 1991 paper by S. Rebelo to simulate this situation. We show that growth in real housing prices can result as economic growth persists, even when population growth is zero. Another finding is that reported increases in housing prices might be underestimated. In particular, the growth rate of a relative price index may converge to zero even when house prices in real terms display sustained growth.     

房地产税、市场结构与房价

本文在住房流量模型的基础上,构建了一个购房者和开发商的住房市场局部均衡模型,考察了完全垄断和完全竞争情形下房地产税与房价之间的关系。结果表明,无论何种市场结构,提高房地产税均导致房价下降;住房市场垄断性越强,房价越高,房地产税对房价影响越大。笔者对1996-2008年中国33个大中城市数据的检验发现,市场结构对房价影响大于房地产税。房地产税增长率每增加1%,房价增长率将减少0.03%;勒纳指数每增加1%,房价增长率将增加0.16%。房地产税与市场结构相互作用将使房价上涨,但影响微不足道。因此,对住宅开征房地产税,将对房价上涨有一定限制作用,但不能有效抑制房价上涨,而增强住宅市场竞争性、降低开发商垄断具有显著效果。     

HOUSING POLICY FOR UTILIZATION OF EXISTING HOUSING

Existing housing is not fully utilized in Japan. We explore the problems that discourage the utilization of the existing housing. We present policy plans to solve these problems, and to activate the existing housing market. Our plans include using a hedonic price function to determine appropriate methods for valuing existing housing, introduction of latent defects insurance for existing houses for sale, encouraging the use of fixed‐term housing leases and an providing an intermediary service between the elderly and next users of their houses. Our plan will accelerate the utilization of existing housing and ease the process for the elderly of selling or leasing existing vacant housing.     

论住房的刚性需求

住房刚性需求是需求收入弹性较大而价格弹性较小的具有一定购买力的消费性需求。在刚性需求内部具有不同级别的"刚性",刚性渐减的顺序是货币化的拆迁性需求、婚房需求、改善型需求。对于不同性质的城市,其住房刚性需求是不同的,政治性城市住房刚性需求比较大,开放性城市刚性需求变化较大;在现阶段,由于房价财富幻觉导致了刚性需求加速效应和叠加效应。制度变迁、房价和收入都是影响住房刚性需求的重要因素。     

INFORMATION FRICTIONS AND HOUSING MARKET DYNAMICS

I examine the effects of seller uncertainty over their home value on the housing market. Using evidence from home listings and transactions data, I first show that sellers do not have full information about current period demand conditions for their homes. I incorporate this type of uncertainty into a dynamic microsearch model of the home selling problem with Bayesian learning. The estimated model highlights how information frictions help to explain the microdecisions of sellers and how these microdecisions affect aggregate market dynamics. The model generates a significant microfounded momentum effect in short‐run aggregate price appreciation rates.     

论住宅需求,居住选址与居住分异

本文从居住区位的需求出发，分析影响居住选址的社会经济因素和城市居住分异的基本规律。根据我国城市社会结构分化的现状和趋势，将我国城市住户划分为工薪家庭、高收入家庭、单身和夫妻家庭、＂空巢＂家庭和＂外来人口＂五种类型，分析预测各类住户居住选址的基本倾向。最后以深圳蛇口工业区为例，剖析我国城市中正在出现和即将出现的居住空间分异现象。
