The labor market effects of foreign owned firms

Foreign firms have a more educated workforce and pay higher wages than domestic firms even after controlling for worker quality, at a given moment in time. This does not imply that foreign ownership improves the labor market outcomes of the workers since foreign investment may be guided by unobservable firm and worker characteristics correlated with schooling or wages. This paper asks whether foreign investors acquire firms with high human capital or wages, or whether foreign acquisition improves these outcomes. Using a matched employer-employee data set, I find that foreign acquisitions of domestic firms have small effects on the human capital and on average wages of the acquired firms. Instead, foreign investors “cherry pick” those domestic firms that are already very similar to the group of existing foreign firms.

基于LSSC的物流企业成长机理——探索性多案例研究

文章基于"资源-能力-成长"的企业成长理论模型,对服务供应链、组织间网络和动态能力理论进行了梳理,报告了物流服务供应链(Logistics Service Supply Chain,LSSC)的网络属性对核心企业成长的影响的研究现状,并提出了文章的研究框架,通过采用探索性多案例的研究方法,对三个典型民营物流企业进行了调查,通过三个案例的一级编码、二级编码和三级编码,得出以下研究结论:物流服务供应链的网络结构和网络关系可以直接促进物流企业成长;物流服务供应链的网络结构和网络关系也可以通过动态能力的作用促进物流企业成长。研究表明:第三方物流企业的成长要通过网络化战略来实现,通过构建物流服务供应链模式,汲取组织间资源、提升企业动态能力并最终实现企业成长。     

负面清单的行业选择与动态调整

负面清单单内行业选择标准,是我国进一步开放自由贸易区的重要问题。巴格瓦蒂的次优理论可以作为制订负面清单对单内行业进行特殊监管的理论基础。当前应把由于市场不完全、信息不完整而存在着外部性扭曲、增长潜力扭曲的行业置入负面清单,进行特殊监管,审慎对等开放。此外,还可以通过对单内行业的动态出单来增加行业活力,扩大开放水平。     

项目进度绩效指标的改进及其动态性预测

传统的挣值方法中,进度指标的预测多表现单期、静态的特性,存在严重的局限性。为了改进和完善挣值管理方法中进度指标体系,在考虑时间序列的基础上,将统计方法引入挣值管理进度指标体系中,用更加科学的方法对项目进度指标进行描述,并在此基础上基于贝叶斯推断方法,加入专家意见,从统计学的角度提出了进度绩效指数的动态预测模型,因而,可以为项目管理者提供科学的据侧依据。     

Gradualism in free trade agreements: a theoretical justification

A notable feature of many recent trade agreements is the gradual, rather than immediate, reduction of trade barriers. In this paper we model trade liberalization as a cooperative relationship that evolves gradually in a non-cooperative environment. We show that specialization, capacity irreversibility and the development of trade-partner specific capital increase the benefit of continuing the liberalizing relationship and decrease, over time, the lowest obtainable self-enforcing tariff. By increasing the penalty of future defection, sunk costs ensure that the self-enforcing trading relationship starts slowly, but once in progress the level of cooperation continues to improve.     

Strategic and tactical price decisions in hotel revenue management

Dynamic pricing techniques allow using a number of variables in a tactical way compared to standard catalogue prices. This study merges in a conceptual model the relevance of the tactical and the strategic dimension of these variables, classified according to their tangible, reputational or contextual nature.To empirically validate the hypotheses, a database of 21.596 price observations was retrieved from booking.com. The study presents a hedonic price function, using the Shapley-Owen decomposition of the R-squared to elicit the importance of each group of factors. Further, a hierarchical cluster analysis measures the presence of heterogeneity across operators.The results show that online reputation is gaining importance over the traditional star rating. Despite the tangible variables remain of paramount importance, the findings suggest the relevant role of contextual variables in short-run price variations. The players operating in the tourism and hospitality industries should integrate these findings when designing pricing strategies.     

An empirical study of dynamic customer relationship management

We apply the Gönül and Shi (1998) approach to the analysis of the optimal messaging and pricing policy mix by studying the past transaction patterns between a local supermarket and its consumers. We develop a dynamic customer relationship management model and investigate the relationship between customer utility and purchasing frequency by modifying the return function of the model discussed in Gönül and Shi (1998). In particular, we extend the analysis to consider a messaging and pricing policy mix, and we use a genetic algorithm in our empirical estimation. When applied to some non-seasonal products in a local supermarket, we find that our model is suitable and far superior to the one-stage model commonly used. Our dynamic model gives the optimal marketing mix strategies in different customer states and the results show that the firm could enjoy a 22% increase in profit.
