THE OUTPUT EFFECTS OF SPATIAL PRICE DISCRIMINATION REVISITED*

ABSTRACT Some prior findings on spatial price discrimination are extended. Under certain spatially defined market conditions, discriminatory pricing is known to yield greater output than does nondiscriminatory f.o.b. mill pricing. However, this seemingly surprising result is based on the form of the basic demand function which is relatively less convex than a certain standard curve. The present paper makes this prior result more general by permitting the assumed basic demand to be relatively more convex.     

SPATIAL PRICE POLICY AND THE DEMAND FOR TRANSPORTATION

For a spatial market of given radius transportation cost per unit sold is less under mill pricing than under any uniform pricing. This is true whether profit-maximizing monopoly prices or welfare-maximizing prices or any other prices are chosen.     

MILL PRICING AND SPATIAL PRICE DISCRIMINATION MONOPOLY PERFORMANCE AND LOCATION WITH SPATIAL RETAIL MARKETS*

ABSTRACT. Most of the monopoly spatial price discrimination literature explicitly assumes uniform population density over space. It also implicitly assumes that firms (plants) are spatially isolated from each other with production and retail points that coincide in location. While departures from these assumptions have been explored separately in the literature, it remains to examine performance and location when these assumptions are relaxed simultaneously. What emerges in this paper is a model where density functions approximate a pair of cities isolated from other cities. Each city has its own retail market, while the location of a single production or wholesale point is determined by characteristics of the two markets. Comparisons of mill pricing and spatial price discrimination found in the spatial monopoly literature can be interpreted as special cases of the more general framework provided here.     

TAX AND FINANCIAL POLICIES FOR THE HOUSING MARKET OF THE 1980s

The imbalance in the age structure of the U.S. population has created conditions for heavy demand and consequently pressures for rising relative prices in the market for owner-occupied single family housing in the 1980s and 1990s. Working in reverse, the unbalanced demographics may well lead to the falling relative price of housing around 2010, the period in which the baby boom generation will be retiring and may wish to liquidate its housing investment. Changes in housing policies during the 1980s could help offset the anticipated costs associated with the swings in demand pressures in the housing market over the next forty years. Current favorable tax and financial policies toward homeownership encourage both the overconsumption of housing and the overinvestment in housing as a retirement asset. Tax and financial policies could be changed to neutralize the attractiveness of owner-occupied single family units relative to alternative types of housing units. To avoid overbuilding for the future, policies could encourage the efficient use of existing housing resources through intergenerational turnover, upgrading of units and neighborhood improvement, and condominium-style conversion of multiunit structures from rental to owner-occupancy. Finally, tax and financial policies toward investment could encourage the baby boom generation to diversify its retirement assets outside of housing.     

THE FEDERAL JUDICIARY, DISCRIMINATION, AND ACADEMIC PERSONNEL POLICY

During the Seventies more than 133 civil rights decisions regarding academic personnel practices were issued by the federal judiciary. Various statutes were utilized to test the validity of personnel record confidentiality, academic credentials in job selection, pension plans and salary systems, and contract renewal, promotion and tenure decisions. Generally academic institutions lost when they challenged the jurisdictional and procedural authority of the government, but won a substantial majority of cases where individual faculty attacked a personnel decision. Overall the most significant trend was the growing willingness of federal courts to require that academic personnel policies conform to broad principles of civil rights law. In the Eighties these principles may substantially alter traditional personnel policies in higher education.     

A SPATIAL AND TEMPORAL AUTOREGRESSIVE LOCAL ESTIMATION FOR THE PARIS HOUSING MARKET

ABSTRACT This original study examines the potential of a spatiotemporal autoregressive Local (LSTAR) approach in modeling transaction prices for the housing market in inner Paris. We use a data set from the Paris Region notary office (Chambre des notaires d’Île‐de‐France) which consists of approximately 250,000 transactions units between the first quarter of 1990 and the end of 2005. We use the exact X–Y coordinates and transaction date to spatially and temporally sort each transaction. We first choose to use the STAR approach proposed by Pace et al., 1998 . This method incorporates a spatiotemporal filtering process into the conventional hedonic function and attempts to correct for spatial and temporal correlative effects. We find significant estimates of spatial dependence effects. Moreover, using an original methodology, we find evidence of a strong presence of both spatial and temporal heterogeneity in the model. It suggests that spatial and temporal drifts in households socio‐economic profiles and local housing market structure effects are certainly major determinants of the price level for the Paris Housing Market.     

旅游产品交换过程中的价格与价值关系探讨

旅游产品的随意涨价,让很多游客感到头痛和不爽,然而业界还在蠢蠢欲动,继续运筹涨价。旅游产品的价格问题实际上关系到一重大的理论问题:由什么来衡量旅游产品价值量。旅游产品在其实现过程中没有物质性的产品传递过程,因此用"商品的价值量取决于社会必要劳动时间,商品按照价值相等的原则互相交换。价格围绕价值上下波动",已经明显解释不通了。感受才是决定旅游产品是否有价值的关键因素。旅游过程中旅游者所获得的感受越深,旅游产品的价值越大,因此它遵循刘氏"发汗定律"。也就是感受的程度是决定价格高低的直接因素。但是感受是一种纯粹的主观心理体验,它是人类社会经济文化背景的直接反映,也是人类文明的区域再现。

ESTIMATION AND HYPOTHESIS TESTING FOR NONPARAMETRIC HEDONIC HOUSE PRICE FUNCTIONS

ABSTRACT In contrast to the rigid structure of standard parametric hedonic analysis, nonparametric estimators control for misspecified spatial effects while using highly flexible functional forms. Despite these advantages, nonparametric procedures are still not used extensively for spatial data analysis due to perceived difficulties associated with estimation and hypothesis testing. We demonstrate that nonparametric estimation is feasible for large datasets with many independent variables, offering statistical tests of individual covariates and tests of model specification. We show that fixed parameterization of distance to the nearest rapid transit line is a misspecification and that pricing of access to this amenity varies across neighborhoods within Chicago.

非摩擦经济:网络时代的经济模式与竞争策略

非摩擦经济是不同于传统经济模式的一种低成本、无摩擦、高效率的全新的经济形态。网络经济是一种典型的非摩擦经济。非摩擦经济不仅对传统的经济学理论提出了严峻的挑战,而且以最为鲜明的力量对社会制度、法律、政府和人们的观念形成巨大冲击,尤其是对企业的运作机制和竞争策略提出了更高要求。因此,现代企业应遵循非摩擦经济的运行规律,重视新技术的应用,提升经营理念,以增强竞争能力。     

PRICE UNCERTAINTY,FACTOR SUBSTITUTION,AND THE LOCATIONAL BIAS OF BUSINESS TAXES*

Consideration of the integrated production-location problem is extended to include several types of business taxes. Many of these taxes are technologically and spatially neutral under certainty, but are shown to be nonneutral when factor prices are stochastic and the firm is risk averse, even when the tax is spatially uniform. Consequently, even a nationally uniform tax can have regional biases and can encourage migration of plants. When factor prices are uncertain, the effects of taxes on output rates, input ratios, and plant location vary with the form of the tax imposed as well as the amount to be paid. Income taxes involve the taxing authority in sharing the risk with the firm and are shown to promote risk taking by the firm and induce the expansion of output. Locational incentives which are mutually beneficial to firms and the government are presented.
