基于特征价格模型的农村集体建设用地流转价格影响因素研究

采用特征价格模型,判别区位特征和产权特征对农村集体建设用地流转价格的影响程度,深入探究农村集体建设流转市场建立的障碍因素。模拟结果显示:区位因素中,繁华程度、道路通达度、农民人均纯收入、基础设施完善度提高1%,农村集体建设用地流转价格分别提高11.3%、10.1%、7.3%、5.9%;产权因素中的使用权能、处置权能、占有权能的完整,集体建设用地流转价格分别提高40.8%、13.4%、8.1%。农村集体建设用地流转市场建立过程中,政策上要从提高农民生产、生活水平和完善社会保障制度着手,逐步改善农村集体建设用地条件,并从法律上明晰农村集体建设用地使用权,赋予占有、使用和处置权能,依靠市场经济手段,激活农村闲置集体建设用地。

A Simple Model of Recent Changes in the Residential Property Market*

A simple model of the Australian residential property market incorporating two form of tenure, owner occupation and renting, is developed. While the supply of housing services is common to both tenures, the demands of tenants and owner occupiers are independent and separate. The equilibrium values of rental and house prices are determined simultaneously in the two sectors. The model is then used to qualitatively assess the likely effects on rents and house prices of some important elements of the September 1985 tax package.     

我国城市工业地价影响因素及力度的计量分析

地价是经济学中的重要课题,它是都市的语言,是都市的环境与功能的综合值。用计量经济学的方法,分供求二方取人口、经济、区位、政府行为等四大板块中的基本要素对我国工业地价的相关性与影响力度进行探讨。从相关性看：城市设施因素与工业地价相关性较弱;大区位因素与工业地价相关性较强。房产税额、耕地占用税额、本年购置的土地面积等政府行为因素与工业地价相关性较强;余者与工业地价相关性较弱。从影响力度看：工业地价对经济、政府行为、区位因素的弹性系数总体呈现一种矛盾、混乱的特征,佐证了中国工业地价违背客观规律性的现象。剔除其混乱因素,仍可看出大区位因素对工业地价影响的力度要大于经济因素,土地类税额对工业地价影响的力度微乎其微;反映了地方政府在工业化过程中对土地的掠夺性开发利用。     

Market News in Commodity Price Theory: Application to the Ethiopian Grain Market

This paper examines the effect of "news" or advance information about future production on competitive storage behaviour and prices using a structural model of commodity markets. In particular, it generalizes the neoclassical storage model to incorporate information on future harvests, while allowing for seasonal production, two features important to African and other developing country grain markets. The model is first developed to suit the case of the Ethiopian grain markets, and a general model is then stated. The effects on welfare and price variability of the addition of news are discussed, as well as changes in key demand and uncertainty parameters. The model is shown to replicate some features of the data better than the model without news, particularly the high autocorrelation in price, and performs better in formal estimation. However, it appears that the incorporation of news still fails to explain the extreme seasonal price movements observed.     

Expectations Heterogeneity and Excessive Price Sensitivity in the Land Market

This paper analyses price behaviour in the land market in which the Walrasian auctioneer is absent. Sellers are informed about the land value and post their asking prices; buyers are uninformed, have different opinions, and decide whether or not to accept the sellers' offers. In this market, sellers are price-makers with probabilisitic market power : they can influence the sale probability through their asking price. Price may be excessively sensitive to unexpected changes in market conditions. Moreover, buyer heterogeneity may accentuate the excessive price sensitivity. It has been shown that, the more heterogeneous their opinions, the more sensitive are prices.

Average Derivative Estimation of Hedonic Price Models

Conventional parametric techniques for estimatinghedonic price models require a correct functionalform. In this paper, we side-step this parametricshortcoming by estimating a hedonic price model usingaverage derivative estimation (ADE). Thissemiparametric approach produces robust estimates ofthe marginal effects without assuming a specificfunctional form a priori. In our application ofthe model to a unique data set on Korean home prices,ADE produced estimates consistent with priorexpectations, providing initial evidence that themodel may represent a viable alternative when usingthe hedonic approach.     

Using a Real‐Options Approach to Model Technology Adoption Under Carbon Price Uncertainty: An Application to the Australian Electricity Generation Sector*

The present climate for investment in electricity generation assets in Australia is uncertain. We develop a real‐options model to contrast the timing of the uptake of various electricity generation technologies under two carbon tax simulations: when a carbon tax of known size commences at a certain date in the future; and a carbon tax of known size commences at an uncertain date in the future. We find that uptake in the future varies significantly depending upon an investor's view of uncertainty and whether the technology is primarily designed to be viable in a market with or without carbon taxes.

中国典型城市群住宅地价空间特征研究

通过对我国长三角、京津唐、珠三角、武汉、中原、成渝六大城市群306个城镇的住宅地价进行研究,试图发现城市群内城市住宅地价的空间分布规律与机理.综合采用地统计的空间插值、空间差异、空间变异分形、相关性理论方法,以SPSS为统计分析工具,对六大城市群城市住宅地价进行了反距离权重插值、余期望系数、分形测度、自相关等全面分析.结果表明我国城市群住宅地价具有以下特征:地价存在显著的地域特点,东部高、中西部低;城市间地价存在明显差异,其中群间差异是造成城市住宅地价差异的主要原因;城市群内城市住宅地价符合等级体系特征,且不同特质的城市群具有不同的分维数;由于城市群发展特点与阶段不同,造成群内地价的不同变化趋势;城市群内城市住宅地价具有一定的关联性,表现在全局性的相关性与局部性的自相关性的空间差异.     

A Spatial Hedonic Approach to Assess the Impact of Swine Production on Residential Property Values

A spatial hedonic model is developed to assess monetary harm of confined animal feeding operations (CAFOs) on property values, taking explicitly into account spatial dependence in property values. Spatial autocorrelation was found in the form of spatial lag dependence, not spatial error dependence. When spatial lag dependence is explicitly taken into account, on average the impact coefficient estimate of a CAFO is reduced by 18%. For example, the impact on the value of the median house ($63,520) 1 mile from a swine facility with 10,000 head fell from  − $6,800 to  − $5,200, or 23.5%. The magnitude of the spatial autoregressive parameter was about 0.2 for the 1-mile distance band, meaning one-fifth of the house value could be explained by the values of the neighboring houses.     

Entry in a Dynamic Model with Equilibrium Price Dispersion with an Application to the Market for Long-Distance Telephone Services

Models of entry based on the traditional models of oligopoly do not allow for price dispersions on homogenous products. Yet, such price dispersions do exist for homogenous products, and a firm does not lose its entire market share when it fails to charge the lowest price. Existing models of equilibrium price dispersion are not designed to analyze entry in a dynamic framework. A dynamic model is developed that allows an analysis of the effects of entry into a previously monopolized market. Despite asymmetric initial shares, the market shares of equally efficient firms tend to equalize over time. An application is the market for long‐distance telephone services following the divestiture of the bell operating companies from AT&T.     

An Australian Housing Model*

A 13-equation model is developed which captures the essential economic features of the housing industry in Australia. The importance of speculative builders and investors is recognized. Empirical results are presented for two key equations. The asset price of existing dwellings (including land) owned by persons is explained by a portfolio choice or generalized asset adjustment model. This asset price then feeds in as a determinant of new private construction, along with construction costs of new dwellings, financial variables and a measure of demand-supply imbalance.     

供给刚性、市场结构与金融——关于房价的Carey(1990)模型扩展

房地产市场是一个非常复杂的市场,其价格决定较一般商品更为复杂,同时房地产又与金融的关系十分密切,因而房价的决定一直是理论界比较关心的问题.本文根据Carey(1990)模型,考虑了不完全竞争市场结构与短期供给刚性等房地产市场的特殊性质,构建了一个房地产价格的模型.我们发现在不同的供给条件下,市场结构和金融资源的政策含义是截然不同的.本文还运用中国的数据对模型进行实证检验,并利用该模型对最近我国宏观调控下房地产市场一些典型性事实进行了解释.

土地垄断供给、纵向市场关系与房地产价格——兼论基于价值链分析的房地产市场竞争促进政策

地价与房价之间并不仅仅是一种成本联系.土地市场与房地产产品市场之间还存在着纵向市场关系,在两个市场均为寡头垄断的情况下,则会存在着双重垄断加成的现象.与上下游产业之间的市场交易关系相比,垂直一体化和垂直约束同样是组织住房生产的有效方式,并有助于增加消费者剩余.此外,促进房地产开发价值链上各环节的竞争,消除其垄断行为,将是降低房价和增进居民福利的重要选择.     

Residential Mobility and the Housing Market in a Two-sector Neoclassical Growth Model

The impact of residential mobility and competitive housing markets on long run growth is examined using a two-sector general equilibrium overlapping-generations model in continuous time. There is an infinity of agents with finite lives who adjust their housing consumption by moving, which is costly. We explore the model's steady-state properties, first with a free housing market, then under rent control when the market clears through restrictions on the frequency of moves. Rent controls do not just reduce welfare; they may increase the steady-state capital-labor ratio.     

The Question of Access to the Japanese Market*

It is now widely accepted that Japan has relatively low official barriers to merchandise, particularly manufactured goods, trade relative to other industrial countries. Yet, Japan's current account and trade surpluses have encouraged the view that there must be special ‘hidden barriers’ to accessing the Japanese market, and a literature has developed on the premise that Japanese business organizations (keiretsu) limit foreign penetration of markets of manufactured goods. This paper surveys the main elements of this literature and questions some of the assumptions upon which recent American policy in this area seems to have been developed.
