Tax Effects in a Model of Product Differentiation: A Note

We investigate how unit (or specific) tax and ad valorem tax affect equilibrium location choice in a model of product differentiation, which includes Hotelling (linear-city) and Vickrey-Salop (circular-city) spatial models as special cases. We find that neither tax affects equilibrium location patterns as long as each firm has the same production cost. Two taxes can yield different location patterns under cost heterogeneity among firms.     

Strategic Environmental Standards, Wage Incomes and the Location of Polluting Firms

The purpose of this paper is tostudy how the choice of environmental standardsby governments is affected by the existence ofwage incomes when firms locations areendogenous. In developed countries labor isunionized, which allows positive wage incomesto arise. Thus, each government has incentivesto persuade firms to locate in its countrysince social welfare depends on suchincomes. But, as pollution damages theenvironment, each government will only try toattract polluting firms to thecountry, to obtain the wage incomes, whenthe valuation of environmental damage showsthat it is low.     

区位势及其BCM估计模型

区位要素的空间聚集形成了区位势，区位势的高低决定了厂商的盈利能力和竞争力，而人们选择理想区位过程中对区位势的判断却受到各种区位因素的影响。BCM估计模型正是在区位因素定性和定量分析相结合的基础上建立起来的区位势估计模型，有助于人们科学选择产业区位。     

产品差异:一般框架与批介

产品差异是现代经济学中涉及面较宽的论题之一,也是产业组织理论的核心领域之一.产品差异是指定位在不同位置的产品集,这些产品或者可以在不同的时间购买,或者包含了不同的特征水平.对产品差异进行研究的理论文献相当丰富,可以从不同的研究视角进行梳理.

Bargaining Strength and Property Class in Office Markets

This paper examines the influence of bargaining power and property class on the prices of heterogeneous goods. Specifically, it explores the impact of buyer and seller characteristics on the transaction prices of office properties. The empirical model is based on the work of Harding, Rosenthal, and Sirmans (2003), which developed a method to distinguish between the impact of buyer and seller attributes on bargaining power and the choice of otherwise unidentified price effects (i.e., property class) in the context of hedonic price models. The data set contains information on transaction prices of office properties in Cook, DuPage, and Lake Counties, Illinois from 1995 to 1997. The results reveal systematic differences in bargaining power and property class for certain groups of buyers and sellers contained within the sample.

Pre-positioning of relief items in humanitarian logistics considering lateral transhipment opportunities

The main objective of this study is to investigate the inclusion of lateral transhipment opportunities into the humanitarian relief chain and to examine the effect of different parameters on minimizing the average distance travelled per item while serving the beneficiaries. Direct shipment model (DT), lateral transhipment model (LTSP) and maritime lateral transhipment model (MLTSP) are developed and compared between each other by using a real life earthquake scenario prepared for the city of Istanbul by JICA (Japanese International Cooperation Agency). Developed mathematical models decide on the locations and number of disaster relief facilities, quantity of relief items to hold at those facilities, and quantity of lateral transhipment between the facilities. Vulnerability of the roads and heterogeneous capacitated facilities are also considered. It can be concluded that both LTSP and MLTSP models gave better results than DT model and lateral transhipment option helps beneficiaries to obtain relief items faster and with higher service level.
