Feedback spillover and analogy-based expectations: A multi-game experiment

We consider a multi-game interactive learning environment in which subjects sometimes only have access to the aggregate distribution of play of the opponents over the various games and sometimes are told the joint distribution of actions and games in a more or less accessible way. Our main findings are: 1) In the presence of feedback spillover, long run behaviors stabilize to an analogy-based expectation equilibrium (Jehiel, 2005). 2) Faced with the same objective feedback, the long run behaviors are sometimes better described by Nash equilibrium and sometimes they are better described by the analogy-based expectation equilibrium depending on the accessibility of the feedback.     

Nachhaltigkeit und Erschwinglichkeit gemeindegetragener Krankenversicherungen in Afrika — Eine Fallstudie aus Nouna Distrikt,Burkina Faso

Many African countries developed national health insurance schemes after independence. However, merely public servants were eligible to subscribe. The majority of the population resides in rural areas where health care services of hospitals and dispensaries were free of charge. The economic crisis of these countries has changed this situation. Currently, almost all health services charge direct user fees so that a severe disease leads to a threat for the entire family of the diseased. Consequently, first community-based health insurances were introduced ten years ago.This paper analyses the effect of these insurance schemes on the service provision for the rural poor with the example of the proposed community-based health insurance in Nouna, Burkina Faso. The insurance can only be sustained if the premium is so high that about 50% of the population cannot afford it. Therefore, this insurance will neither benefit them nor will their situation improve. We have to ask whether a programme that betters the state of the well-off while leaving the condition of the poor unchanged is fair and just. For this purpose different aspects of equity are discussed. The author concludes that the premium-induced exclusion of 50% of the population from the insurance is only acceptable if the privileged use this benefit for economic growth which will finally benefit the poor.     

Fixed-mobile integration

Fixed-line incumbents often also own the largest mobile network. We consider the effect of this joint ownership on market outcomes. Our model predicts that while fixed-to-mobile call prices to the integrated mobile network are more efficient than under separation, those to rival mobile networks are distorted upwards, amplifying any incumbency advantage. This result is robust to changes in the competitiveness of the fixed market and to the presence of fixed-mobile substitution. As concerns potential remedies, a uniform off-net pricing constraint leads to higher welfare than functional separation, and even allows to maintain some of the efficiency gains.     

Working in the digitized economy: HRM theory & practice

In our introduction to this special issue on the gig economy, we provide some context to how and why this phenomenon should be studied, with a particular emphasis on Human Resource Management. We then describe the four articles that comprise the special issue, and we note some common themes. Our introduction concludes with some suggestions for future research on the gig economy.

Analysis of factors influencing the development of transport infrastructure until the year 2030 — A Delphi based scenario study

In this paper, we present the findings of a web-based real-time Delphi study concerning the factors which will influence the future development of the transport infrastructure until the year 2030. Intensifying globalization, increased urbanization, ongoing shortages in public finances, and the requirements of a more demanding and growing world population are some of the challenges, which global transport will face. This research identifies, assesses, and integrates long-range developments of various factors, such as supply and demand, financing, competitiveness, and sustainability, which will affect the future of the transport industry and its infrastructure. Results are presented in a final probable scenario, which is divided into four different scenario aspects. Moreover, managerial and governmental implications for strategy and policy development are discussed.     

Entrepreneurs' perceived exit performance: Conceptualization and scale development

Recently, research on entrepreneurs who exit their firms has intensified. Scholars agree that the outcome of such entrepreneurial exits needs to be assessed based on the individual entrepreneur's perception and on multiple dimensions. Yet, to date we lack theory and measures that capture this outcome, which we define as entrepreneurs' perceived exit performance (PEP). This study introduces a theoretical framework for the PEP construct and develops a scale to measure it along four dimensions: personal financial benefits, personal reputation, employee benefits, and firm mission persistence. We discuss the wide applicability of the scale and a variety of research opportunities.     

危机后的全球金融中心

金融中心之间的国际竞争极为激烈,而全球金融危机将加速其格局的改变。美国和欧盟的金融市场仍旧提供着全球近四分之三的金融服务,但危机之后。它们在许多市场领域的活动都明显萎缩了。新兴金融市场,尤其是亚洲．在过去几年内迅速增长,并且开始加速它们对传统金融中心的追赶步伐。北京、首尔、深圳、上海和迪拜等新兴金融中心自2007年以来国际排名迅速提高,在竞争力水平方面,首尔上升了42％,北京27％,孟买22％,上海16％。关于金融中心的未来竞争态势,我们总结出了四个重要的影响因素：第一,由于既有的市场优势和良好的经济环境,伦敦、纽约、香港和新加坡等传统全球金融中心在危机后仍是全球金融的集聚地;第二,长期来看,新兴金融中心可能在建设市场环境的规模和广度方面取得成功,从而进入全球金融中心的第一集团,而此次危机可能加速这一趋势;第三,地区和区域性金融中心可能会寄希望于市场参与者与政策制定者重新将注意力放到国内市场,然而这种优势很可能不会持续太长时间;第四,良好的监管体系是金融中心的重要竞争优势,那些不遵循国际监管规则的金融中心将面临越来越大的国际政治压力和指责。
