Price competition in markets with customer testing: the captive customer effect

We introduce product differentiation into the analysis of price competition in markets where suppliers test customers in order to assess whether they will pay for received goods or services. We find that, if the degree of differentiation is sufficiently high, suppliers may improve the average probability that their clientele will pay by charging higher prices. This helps suppliers to sustain high prices in equilibrium. Moreover, endogenizing locations in product space, we demonstrate that the high price level can be implemented in a pure-strategy subgame-perfect equilibrium with a high degree of differentiation. This is in contrast to the original Hotelling model with linear travel costs where a pure-strategy subgame-perfect equilibrium fails to exist.     

A typology of mixed methods research designs

The mixed methods paradigm is still in its adolescence, and, thus, is still relatively unknown and confusing to many researchers. In general, mixed methods research represents research that involves collecting, analyzing, and interpreting quantitative and qualitative data in a single study or in a series of studies that investigate the same underlying phenomenon. Over the last several years, a plethora of research designs have been developed. However, the number of designs that currently prevail leaves the doctoral student, the beginning researcher, and even the experienced researcher who is new to the field of mixed methods research with the challenge of selecting optimal mixed methods designs. This paper presents a three-dimensional typology of mixed methods designs that represents an attempt to rise to the challenge of creating an integrated typology of mixed methods designs. An example for each design is included as well as a notation system that fits our eight-design framework. This paper won the James E. McLean outstanding paper award.     

并购类型会影响中国企业技术并购绩效吗

有学者发现技术相关及互补程度对技术并购绩效影响显著,这是否意味着并购类型会影响中国企业技术并购绩效呢？利用2006-2015年中国企业219起技术并购相关数据,通过实证分析及稳健性检验发现,横向技术并购对企业并购绩效具有抑制作用,纵向技术并购对企业并购绩效具有促进作用,混合技术并购对企业并购绩效影响不显著。因此,中国企业在横向并购前应当储备足够资金,充分调动研发人员并购后的积极性,提高并购后自主研发效率;中国企业并购应优先选择与自身技术互补的企业,通过协同创新提高绩效;中国企业在混合技术并购时需要提前熟悉被并企业的技术知识,并购后尽力避免被并企业人才流失。     

宜控还是宜参？国有股权与民营企业双元创新：逆向混改视角

国有资本逆向入股民营企业追求“国民”间长期合作而不是短期机会主义行为。基于引入国有股权的民营上市公司数据进行实证检验,结果表明,参股性国有股权对民营企业渐进式创新和颠覆式创新均具有促进作用,而控股性国有股权则不利于民营企业双元创新。进一步分析发现,市场化程度越高,参股性国有股权对民营企业双元创新能力的促进作用越强,而控股性国有股权对民营企业双元创新能力的抑制作用越弱。市场化程度对国有股权的创新效应具有“扬长避短”之效。在采用替换核心变量和变量滞后取值等方法进行稳健性检验后,上述结论依然成立。结论可为推进国有资本监管改革和深化混合所有制改革提供理论与实证依据。     

基于MF-VAR的混频数据非线性格兰杰因果关系检验

研究目标：提出一种针对混频数据非线性格兰杰因果关系检验的方法。研究方法：在混频向量自回归模型（MFVAR）的基础上提出构造Wald统计量,通过模拟实验和实证研究考察统计量的性质。研究发现：模拟实验结果表明该检验相对于其他混频检验和低频检验具有更优的性质,并且对检验式误设具有稳健性。进一步针对中国经济增长与消费者信心因果关系的实证研究证明,混频检验与低频检验得出的结论有很大差异,混频检验得出的结论更符合经济理论。研究创新：利用自助法修正统计量在有限样本下产生的水平扭曲,利用典型相关分析实现了数据降维。研究价值：在检验不同频率变量之间的非线性格兰杰因果关系时避免了信息损失和虚增。     

THE SCOPE FOR NON‐PROFIT OBJECTIVES IN A MIXED OLIGOPOLY UNDER INTERNATIONAL COMPETITION

We ask how the scope for non‐profit objectives in a state‐owned enterprise (SOE) in a mixed oligopoly changes because of competition from firms in another country. There is no change if costs and demand are given, unless the trade partner is a low‐cost country. However, the scope for non‐profit objectives is limited by the country's relative size if wages are market‐clearing and if workers and firms are stationary, because of reduced competitiveness caused by higher real wage rates. The total surplus is then not affected by the actions of the SOE. International trade does not otherwise reduce the scope for its non‐profit objectives if workers and firms are mobile, but productivity differences might require restrictions in order to avoid a complete relocation of the workforce in either country.

Discrete choice model analysis of mobile telephone service demand in Japan

This paper analyzes the demand for mobile telephones including second generation (2G) and third generation (3G) by using a discrete choice model called a mixed logit model. First, we examine the substitution patterns of the demand for mobile telephones and show that demand substitutability among alternatives is stronger within the provider nest category than within the standard nest category in mobile telephone services. The closest substitute for NTT’s 3G service is NTT’s 2G service, rather than KDDI’s 3G service, for example. Second, we investigate the elasticities of demand for various functions including e-mail, Web browsing, and moving picture delivery. Consequently, we cannot observe marked differences between 2G and 3G services based on these calculated elasticities, indicating that it takes time for 3G subscribers to gain proficiency with such new services.      

混合所有制企业竞争力与股权结构关系研究——基于制造业的分析

文章选择制造业行业进行研究,通过建立混合所有制企业的竞争力指标体系,用因子分析法对符合条件的388家样本企业在2010-2014年的竞争力进行测评,然后研究了混合所有制企业竞争力与股权结构之间的定量关系,发现混合所有制企业竞争力与股权集中度呈"U"形关系、与股权制衡度呈正相关关系、与高管持股比例不相关,最后结合样本企业当前的股权结构现状,提出了提升混合所有制企业竞争力的对策,包括:适当降低第一大股东持股比例、提高第二大股东至第五大股东的合计持股比例、有意识的打造第二大股东、加大高管持股力度等。
