中国移动通信业价格竞争本质解析

中国移动通信业的价格竞争,经过了无价格竞争阶段、显性价格竞争阶段、隐性价格竞争阶段、后价格竞争阶段的演化,体现了制度调节与市场选择并行的内在规律性,也增进了市场协调、提高了市场效率。中国移动通信业价格竞争具有非合作博弈的特性,行业管制与市场选择共同推动了竞争的有序化。因此,要实现中国移动通信市场的有效竞争,市场机制的作用是有限的,还离不开适当的政府行政参与下的不对称管制政策,而且不对称管制政策也需要根据市场变化进行调整和改进。     

基于生命周期的智力资本对企业创新能力的影响研究

进入知识经济时代后,智力资本成为提高企业创新能力的关键要素。本文以2014年上市制造业企业作为研究对象,分析智力资本与企业创新能力的关系。研究发现,不同的生命周期中,人力资本、结构资本和关系资本对企业创新能力的影响程度不同。其中在成长期时,人力资本和结构资本对企业创新能力影响较大。在成熟期时,人力资本、结构资本和关系资本都正向显著影响企业创新能力。在衰退期时,人力资本和关系资本对企业创新能力影响较大。研究结果可以为上市制造业企业有效实施智力资本的积累,进一步实现企业创新提供借鉴。

Strategic nonlinear pricing

The objective of this paper is to examine the role of nonlinear strategies in a standard oligopoly framework. We demonstrate that nonlinear pricing may indeed emerge as an equilibrium strategy, but only when firms produce differentiated products, when one firm retains market power due to a cost advantage, or as part of an equilibrium in mixed strategies. In addition, we examine the role of nonlinear pricing in a spatial-competition framework. Our main conclusion is that in highly competitive markets, nonlinear pricing strategies are not likely to emerge as an equilibrium.

Competition and efficiency in the MENA banking region: a non-structural DEA approach

The goal of this article is to empirically assess the relationship between competition and efficiency in the banking sector of Middle East and North African (MENA) countries spanning the period 1997–2011. To measure the level of competition, the article estimates the non-structural indicator known as the H-statistic, while the level of bank efficiency is estimated through the nonparametric methodology of the Data Envelopment Analysis (DEA) and the Bootstrap Data Envelopment Analysis (BDEA), respectively. The empirical results are robust under six econometric methodologies, providing sufficient evidence for the presence of a one-way (negative) Granger causality, running from efficiency to competition. The empirical findings lead to the rejection of the ‘Efficient Structure Hypothesis’, implying that increases in competition do not precede increases in cost efficiency.     

Market competition, social welfare in an entry-constrained differentiated-good oligopoly

This paper studies a differentiated-good oligopoly where the socially optimal number of firms (varieties) may be smaller or greater than under the free-entry equilibrium. We show that, under certain conditions, social welfare may be higher when entry is restricted into the industry.

Protection for sale under monopolistic competition: Beyond the CES

We extend the protection for sale model of Grossman and Helpman (1994) by introducing a general model of monopolistic competition with variable markups and incomplete pass-through. We show that the structure of protection emerging in the political equilibrium not only depends on the weight attached by the government to consumer welfare when making its policy decision, but also on the degree of market power of firms and on the terms-of-trade variations due to the degree of pass-through. Our results highlight the importance of preferences in shaping the structure of protection and are consistent with the occurring of protectionism also in unorganized industries.     

Voting with your feet: Political competition and internal migration in the United States

Do people “vote with their feet” in response to a lack of political competition? Since political competition is associated with higher growth and welfare, with the free movement of labour, we argue that it should also encourage inward migration. We test this hypothesis by using data from the US and find a strong positive relation between political competition and net migration. This result is robust to alternative specifications, alternative samples and addressing endogeneity using the Voting Rights Act to instrument for political competition. The effect is economically large, specifically, we find that an increase in political competition in the order of magnitude observed in US Southern states during the post-war period leads to an increase in net migration by between 27 and 44 individuals per 1000 population.
