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。     

An Application of the Hedonic Price Model to the Perth Residential Land Market*

This paper presents the results of an application of the Rosen-Freeman hedonic price model to the Perth (Western Australia) residential land market. A sample of over two thousand market transactions is used to estimate the value of residential land attributes. Major emphasis is given to those particular land attributes that are subject to public regulation and to the policy implications that follow.     

Hedonic Pricing of Agriculture and Forestry Externalities

In this study, the hedonic price method was used toidentify and monetarize some of the external effectsof agricultural and sylvicultural activities. Weexamined the renting price of ruralself-catering cottages, or gîtes. Intensivelivestock farming caused the renting-price ofgîtes to decrease, whereas permanent grassland hadthe opposite effect.

An Index Approach to Measuring Product Differentiation: A Hedonic Analysis of Airfares

The main objective of this paper is to introduce an Allen-type index of differentiation based on cost functions. With this index, we create an economic measure of product differentiation that quantifies differences between products. Applied research has some generally accepted economic measures, for example, the Herfindahl–Hirschman Index for market concentration, or the Gini coefficient for inequality. Product differentiation, however, does not yet have an established measure. Our objective is to fill that gap and introduce a measure that can be used in market-related applied research such as market power, antitrust, price indexes, or market strategy. To operationalize the index, we introduce the concept of a core product and use cost functions to measure the degree of differentiation from the core product. To demonstrate the use of the index, we study the effect of product differentiation on price formation in the airline industry using an enhanced hedonic model. The model is empirically tested on 103,980 observations of quarterly US domestic airfare data between 2002 and 2016 and shows that product differentiation has a significant effect on both price and mark-up.     

开盘价操纵与定价效率——基于高频数据的开盘价操纵识别模型

本文利用2007-2018年中国A股上市公司作为研究样本,基于异常交易行为构建了开盘价操纵识别模型,并利用分时高频数据实现了疑似开盘价操纵行为的监测.基于识别模型侦测的疑似开盘价操纵行为,本文实证检验了开盘价操纵与定价效率之间的关系.研究结果表明:开盘价操纵提升了 日内股价短期收益率的可预测性,降低了定价效率.开盘价操纵吸引了散户投资者的流入,进而降低了定价效率,受操纵股票的散户投资者参与程度越高,定价效率越低.同时,信息不对称程度越高、投资者情绪越高涨、羊群行为越严重,开盘价操纵对定价效率的损害程度越大.     

特征价格指数编制研究——我国计算机硬盘价格实证分析

文章首先讨论特征价格指数编制理论,具体阐述了特征价格指数的三种编制方法:通过特征价格函数直接编制的方法,引入时间虚拟变量的方法,以及特征质量调整的方法。最后以2005年1月至2006年12月我国计算机硬盘价格为例,编制并实证了我国计算机硬盘特征价格指数,并分析硬盘价格的变化趋势。     

我国畜产品价格波动分析——基于ARCH类模型

运用ARCH类模型对我国主要畜产品的价格波动率进行了分析。结果表明:牛肉、羊肉和鸡肉的价格波动具有显著的波动积聚性,鸡蛋价格波动没有显著的异方差效应;除牛肉市场外,羊肉和鸡肉市场不具有高风险、高回报的特征;猪肉、牛肉、羊肉和鸡肉的价格波动没有非对称性。认为应在畜产品市场出现大的价格波动时及时采取平抑措施,且政府需规范畜产品市场秩序、完善畜产品市场制度。     

金融工程视角下B-S模型与金融期货价格研究

金融衍生工具的定价理论与方法一直是金融界较为关注的热点问题.在金融市场中,由于金融衍生工具的价格都受一种不确定因素的影响,因而对金融衍生工具的定价是非常困难同时也是非常重要的问题.在布莱克和舒尔斯的原始论文里,是通过变量替换把上述微分方程变换成一个标准的抛物型方程(热扩散方程)来求解,其中主要涉及一些较高深的数学理论,而本文的主要贡献在于:首次从金融工程视角推导了布莱克-舒尔斯定价模型,并对布莱克-舒尔斯定价模型边界化,得到了金融期货的价格公式.本研究对于解决我国金融衍生工具的科学性定价问题具有非常重要的理论与现实意义.     

The Amenity Value of English Nature: A Hedonic Price Approach

Using a hedonic property price approach, we estimate the amenity value associated with proximity to habitats, designated areas, domestic gardens and other natural amenities in England. There is a long tradition of studies looking at the effect of environmental amenities and disamenities on property prices. But, to our knowledge, this is the first nationwide study of the value of proximity to a large number of natural amenities in England. We analysed 1 million housing transactions over 1996–2008 and considered a large number of environmental characteristics. Results reveal that the effects of many of these environmental variables are highly statistically significant, and are quite large in economic magnitude. Gardens, green space and areas of water within the census ward all attract a considerable positive price premium. There is also a strong positive effect from freshwater and flood plain locations, broadleaved woodland, coniferous woodland and enclosed farmland. Increasing distance to natural amenities such as rivers, National Parks and National Trust sites is unambiguously associated with a fall in house prices. Our preferred regression specifications control for unobserved labour market and other geographical factors using Travel to Work Area fixed effects, and the estimates are fairly insensitive to changes in specification and sample. This provides some reassurance that the hedonic price results provide a useful representation of the values attached to proximity to environmental amenities in England. Overall, we conclude that the housing market in England reveals substantial amenity value attached to a number of habitats, designations, private gardens and local environmental amenities.     

行业属性对劳动报酬的边际效应及其细部特征——基于分位数回归模型的实证研究

目前学术界普遍使用的基于最小二乘法的传统线性回归方法不但不能分析行业属性对劳动报酬边际效应的细部特征,而且行业劳动报酬分布具有的非正态分布特征还会严重影响模型的估计结果,误导分析结论,而现代计量经济学中的分位数回归模型可以有效地解决上述问题.文章使用分位数回归模型方法对影响劳动报酬的行业属性变量进行了选择,测算了有关行业属性变量在不同部门、不同分位点上对劳动报酬的边际效应,分析了边际效应的细部特征与变化规律.     

写字楼租金差异的特征价格分析——基于杭州的实证研究

写字楼作为商业地产的重要组成,已成为当前投资开发的热点,写字楼租金的研究也越来越具有实践意义。本文在文献回顾的基础上,采用特征价格方法,对我国浙江省杭州市写字楼市场进行实证研究。研究结果表明,距市中心距离/次级市场、建筑年龄、建筑形象等因素对写字楼租金具有显著影响,但影响机理异于国外的经验研究;建筑面积、楼层数等变量的影响不显著,这也异于已有的经验研究。后续研究可从研究对象、研究样本、变量选取与度量等方面深入改进。     

基于价格上限的输配电价格管制模型改进研究

由于输配电环节具有自然垄断特性,因此必须接受监管,但随着电力的市场化改革,旧有的监管机制存在一定缺陷,而基于绩效的价格管制模型又不能直接适用于我国的国情。本文提出了一种基于价格上限的价格管制改进模型,在一般价格上限模型中引入电能质量因子,从而很好地克服了该模型导致质量恶化的缺陷,提高了模型的适用性。文中还详细介绍了电能质量因子的确定问题,并对该质量因子进行了算例分析。     

金融资产定价异常与资产定价模型的扩展——基于委托-代理理论视角的研究

对于金融资产定价异常现象,本文基于信息角度将信息不对称分为可识别的逆向选择效应、可识别的道德风险效应、不可识别的逆向选择效应和不可识别的道德风险效应四个部分,并在此基础上利用委托-代理理论对资产模型进行了扩展,得出了信息不对称下扩展的资产定价和代理成本资产定价模型。进而论证了动态资产定价模型、羊群效应资本资产定价模型与FF三因素模型只是扩展的资本资产定价模型的一个特例,从而为动态资产定价模型,羊群效应资本资产定价模型与FF三因素模型提供了微观基础。     

Price Competition and Product Differentiation when Goods have Network Effects

Abstract. The objective of our approach is to develop a model that captures horizontal product differentiation under environmental awareness with price competition whereby environmentally friendly products are costlier to produce. As an example, we refer to automobile producers offering cars with a gasoline-powered engine and one with a natural gas-powered engine. The network of petrol stations provides the complementary good. We use a two-stage game in prices and characteristics to analyse the market structure. In order to find out whether a private decision on the type of engine coincides with a socially optimal product differentiation, we determine the position of the two types of engine by a welfare-maximizing authority.

我国地方性商业银行存款保险定价研究——基于预期损失定价模型的分析

随着我国经济和金融的不断发展,建立适合国情的存款保险制度已非常迫切。虽然存款保险制度存在逆向选择及道德风险,但是研究表明:合适的存款保险定价可以减少自身存在的问题,给金融机构的稳健经营带来更大保障。选择地方性商业银行作为研究样本,采用BP神经网络及D-S证据理论相结合的方法,用预期损失定价模型来计算存款保险费率,对这些金融机构的信用等级进行简单评定,并结合国内外相关经验给出预期损失率,从而得出存款保险费率。     

Risk and Information: a Hedonic Price Study in the New Zealand Housing Market*

This paper employs the hedonic price approach developed by Rosen (1974) and recently extended to study the effects of potential natural hazards on consumer behaviour. Hedonic prices are used to estimate home buyers' willingness to pay to avoid a high-pressure gas pipeline installed in a residential area Studies of risk and information (e.g. Brookshire et al., 1985, Smith and Johnson, 1988) suggest that the subjective probability of a hazard occurring differs from the objective probability. If we allow for this, and relax the assumption of full information on the part of home buyers, our theoretical analysis indicates that a single hedonic price is not sufficient because hedonic prices are likely to change with a change in information. Our empirical analysis of cross-sectional data across time is in accord with the theoretical model, although not highly significant
