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.     

替代、互补及互嵌:企业与市场关系的新考察

在现实世界中,企业市场关系呈现出替代、互补及互嵌等多种特征,使得单一的“替代”说或“互补”论均缺乏足够的解释力。本文从交易费用角度将交易关系分为三种类型并指出企业和市场谁更有利于交易费用的节约,主要取决于交易品的特征以及交易本身的具体职能。企业其实是一种通过非人力资本和人力资本、人力资本和人力资本间相互交易以实现生产功能的特殊履约机制。这样就不难理解,只有部分交易可以通过企业与市场间的相互替代来提高效率,而更多的交易则须通过改善企业内部管理或改进市场制度本身来提高其效率。     

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.     

论企业本质、公司治理与财务会计理论的契合:资本保全视角

基于企业本质从价值角度描述为财务资本、人力资本、组织资本与社会资本的一个不完全契约组合,公司治理就是保证这一契约组合有效执行的制度安排,而现代财务会计在理论与实践上更接近于公司治理.本文利用资本保全概念将企业本质、公司治理与财务会计理论整合为一个完整的理论框架.

The survivorship bias, share price effect, and small firm effect in Canadian markets

After controlling for survivorship bias, we examine the relation between average returns, firm size, and price levels for Canadian stocks during the 1975-1994 period. Our findings indicate that there is a significant inverse share price level effect in Canadian markets. When we compare the results of the overall sample with the groups of surviving firms and delisted stocks, the latter group shows strong performance for large-size, high-priced stocks. Evidence that supports an independent size effect is less clear for Canadian stocks. A small size effect exists only among the higher share price denominations, which suggests a confounded size-price effect. Although the delisted group returns are statistically different from those of the survivor and the overall groups, which implies some evidence of survivorship bias, the difference between the survivor group and the overall group is weak at best.     

Antecedents and consequences of corporate governance reform: the case of Germany

The paper examines the antecedents and consequences of the voluntary adoption of corporate governance reform in firms embedded in a relationship‐based governance system with less protection of minority shareholders. In such locations, ownership structure should be a key determinant of governance reform. Firms with dispersed ownership are likely to face agency problems but may lack sufficient ownership power in the hand of external owners for adoption to occur. Extensive ownership by external parties facilitates adoption but decreases the need and motivation to adopt governance reform. We examined the adoption of stock‐based incentive plans and transparent accounting regulations (e.g., greater disclosure to shareholders) among large German firms (DAX 100) during the late 1990s. We found an inverse ‘U’‐shaped relationship between ownership concentration and governance reform. In addition, we found that firms adopting governance reform were more likely to engage in corporate divestitures and achieve higher levels of market performance than firms not adopting governance reform.
