Limit-pricing as Bertrand equilibrium

Summary. We consider a Bertrand duopoly model with increasing returns to scale where one of the firms have a cost advantage and prices vary over a grid. We find that typically more than one equilibria exist. However, there are only two perfect equilibria. Moreover, as the size of the grid becomes small, both these equilibria converge to the limit-pricing outcome. Received: February 25, 2000; revised version: January 9, 2001

风险资本规模与最优投资组合

对于任何一个风险投资基金来说,都涉及到投资组合规模问题。由于在投资策略中奉行积极干预的策略,风险投资家耗费了大量的精力和时间。因此,风险资本规模的扩大对风险投资家的投资结构可能会产生影响。这就引致出风险投资最优投资组合的问题,并涉及对风险投资收益率的影响。     

Policy instruments for curbing CO2 emissions: The case of the Netherlands

Taxes may seem to be the most attractive instrument for curbing the emissions of carbon dioxide. This paper, however, argues that environmental taxes involve a number of serious complications — especially in an open economy riddled with market imperfections like the Netherlands. Therefore, a wide-ranging policy mix is called for. As far as households and sheltered sectors are concerned, regulation can continue to play a major role. Within the context of unilateral policies aimed at exposed sectors, the combination of subsidies and voluntary agreements may be more cost effective than the tax instrument.This paper was prepared for a conference on Energy Taxation in Europe organized by the Stichting voor Economisch Onderzoek (SEO) and held on December 13, 1991 in Amsterdam, the Netherlands. The author would like to thank Sijbren Cnossen, Jarig van Sinderen and one anonymous referee for helpful comments on an earlier draft.     

四大国有商业银行的收缩战略研究——从规模经济的角度探讨银行实施收缩战略的必要性

在不断出现的全球银行业并购案例中 ,人们往往只重视对商业银行的扩张战略进行研究 ,但是收缩战略在当今的银行业中同样发挥着重要的作用。本文首先通过对银行业的背景和银行适度规模的分析 ,探讨商业银行实施收缩战略的原因 ,然后从实证的角度对我国国有商业银行的规模及其效益进行分析 ,证明实施收缩战略的必要性。文章最后针对我国的现实情况 ,提出实施收缩战略的两点具体措施。     

A DEA Approach to Understanding the Productivity Growth of Malaysia's Manufacturing Industries

This paper seeks to explain the productivity growth performance of Malaysia's manufacturing sector using a panel data of 28 industries from 1981–1996. Here, the data envelopment analysis technique is used to calculate and decompose the Malmquist index of total factor productivity (TFP) growth into technical change, change in technical efficiency and change in scale efficiency. This allows the identification of the sources of productivity growth which is crucial for policy formulation. It was found that the annual TFP growth of the Malaysian manufacturing sector was low at 0.8% and this was driven by small gains in both technical change and technical efficiency, with industries operating close to optimum scale.     

中国银行业规模经济和范围经济的实证研究——基于复合成本函数的分析

本文首次在国内利用复合成本函数估计我国国有商业银行和股份制商业银行1998——2003年的成本函数,并计算出各自的规模经济和范围经济。复合成本函数把投入价格的对数二次项和产出的二次项结合起来,具有优良的实证研究性质。实证研究结果表明:时间对我国银行业的规模经济和范围经济影响不显著;国有商业银行和股份制商业银行都存在着轻微的规模不经济和范围不经济,国有银行略好于股份制银行。我国商业银行的两种产出——存款和贷款不存在成本互补性。     

Inter‐temporal economies of scope,organizational modularity,and the dynamics of diversification

The question of whether corporations add value beyond that created by individual businesses has engendered much debate in recent years. Some of this debate has focused on the pros and cons of related vs. unrelated diversification. A standard explanation of the benefits of related diversification has to do with the ability to obtain intra‐temporal economies of scope from contemporaneous sharing of resources by related businesses within the firm. In contrast, this paper deals with inter‐temporal economies of scope that firms achieve by redeploying resources and capabilities between related businesses over time, as firms exit some markets while entering others. The transfer of resources due to market exit distinguishes our treatment of inter‐temporal economies of scope from standard intra‐temporal economies of scope. In addition, these inter‐temporal economies can benefit from a decentralized and modular organizational structure. This ability to obtain inter‐temporal economies of scope via organizational modularity and recombination suggests that corporations do not necessarily need a high degree of coordination between business units in order to benefit from a strategy of related diversification.
