Ex-post Analysis of Mobile Telecom Mergers: The Case of Austria and The Netherlands

Recently there has been an increased attention towards the ex-post evaluation of competition policy enforcement decisions and in particular merger decisions. In this paper we study the effects of two mobile telecommunication mergers on prices. We apply a standard difference-in-differences approach which is widely used in the literature on ex-post evaluation of mergers. For the Austrian T-Mobile/tele.ring merger, we conclude that after the acquisition (for which remedies were imposed) prices in Austria did not increase relative to the considered control countries. For the Dutch T-Mobile/Orange merger, we observe an increase in the mobile tariff prices in the Netherlands in the analysed period, relative to the control countries. We cannot firmly establish whether this price increase was exclusively caused by the T-Mobile/Orange merger or in part by possible price effects brought about by the KPN/Telfort merger consummated two years earlier in the Netherlands. However, we believe that such price increase could be linked to the structural changes brought by both KPN/Telfort and T-Mobile/Orange mergers together.     

Family Business in Sub-Saharan Africa Versus the Middle East

This paper examines the impact of culture on family businesses in two regions of Africa: sub-Saharan Africa and the Middle Eastern region. Nine cross-culturally comparable “etic” dimensions are used to assess characteristics of family firms in both regions, based on the Culturally-sensitive Assessment System and Education (CASE) project. Overall, the characteristics of family businesses in the regions are associated with their distinctive cultures. Several commonalities are found; however, the observed differences suggest directions for the African family businesses to become the engines for national and regional development. Implications for further research and for practice are identified.     

State of the Art der Forschung zum Interkulturellen Konsumentenverhalten. Eine Analyse der Literatur von 2005 bis 2010

Companies entering different country markets frequently face the challenge of adapting their marketing-mix to specific value orientations. Cross-cultural consumer research aims at supporting this adaption process. Therefore, research tries to develop theories that explain under which circumstances consumer behavior is culture-free or culture-bound. The present article conducts a literature review in order to examine how the field has developed from 2005 to 2010. The review systematically evaluates 92 relevant studies considering the research approach, the selection of cultural units, the operationalization of culture, and the type of consumer behavior. The analysis reveals that the field is growing in terms of quantity and variety. Additionally, recent studies have overcome some methodological problems of cross-cultural research. The article condenses the most relevant findings and derives implications for further research.     

How to communicate sustainable tourism products to customers: results from a choice experiment

This multiphase and empirical study explores the best communication style for reaching different international tourism markets and provides an understanding of how purchase decisions could be better influenced in travel brochures. A pre-test experiment evaluated the perceived emotionality and rationality of communication elements in a fictional travel brochure designed for a typical beach holiday but managed according to sustainability principles. In phase two, a choice experiment was conducted to test how Swiss, German, British and US travellers could be influenced by varying visual and textual communication elements in the fictional brochure (based on Mexico for US respondents and Menorca for all others). The choice experiment produced 3006 responses from an online survey in the four countries. Results confirm a general preference for emotionally laden communication styles for sustainable tourism products, while respondents were indifferent to the emotionality of standard product feature communications. Respondents did not show a preference for the inclusion of a graph explaining the product's sustainability attributes.     

Another look at comparable worth’s impact on black women

In a 1986 article in theReview, Julianne Malveaux discussed the use of a comparable worth strategy for improving the economic position of black women (and men). In this response, the authors point out that some occupational channeling occurs prior to labor market entry and also suggest economic factors that could lead to reduced economic opportunity for some women as a result of the implementation of a comparable worth policy.     

Positioning hierarchy in enterprise system change

There is a widening gulf in change literature between theoretical notions of evolving organisational form and the emerging reality that old and new organisational structures coexist. This paper explores this dichotomy in Enterprise Resource Planning change. It develops a cellular hierarchy framework to explain how different types of hierarchy coexist within the same organisation during the implementation of Enterprise Resource Planning.     

Quasi-hyperbolic discounting and social security systems

Hyperbolic discounting has become a common assumption for modeling bounded rationality with respect to individual savings decisions. We examine the effects of hyperbolic discounting on the comparison of alternative social security systems. We show that this form of bounded rationality breaks the equivalence between funded and pay-as-you-go (PAYG) systems established in Sheshinski and Weiss [Sheshinski, E., Weiss, Y., 1981. Uncertainty and optimal social security. Quarterly Journal of Economics 95, 189-206]. Intergenerational transfers within a PAYG economy are usually secured by the social security system and independent of longevity, whereas this is not the case for the funded economy. The savings level under hyperbolic discounting is lower than under exponential discounting [Laibson et al., 1998], but the ratio between the savings level under hyperbolic discounting within a funded economy and a PAYG economy depends on the effectiveness of the commitment devices. It is shown that if individuals are hyperbolic discounters, then in a PAYG economy any change in the mandated level of intergenerational transfers is neutralized by individuals’ voluntary bequests. This does not apply to a funded system.     

Computer‐Aided Statistical Instruction—Multi‐Mediocre Techno‐Trash?

The very soul of statistics are data, but few students actually collect data as part of their statistical journey. The impediments to real data collection exercises are very real—they are logistically difficult to set up, expensive, and may not work because of extraneous events outside the control of the instructor. Computer‐aided laboratories are a way to bring many of the benefits of actual data collection to students at a fraction of the cost and can be easily controlled by the instructor. There are many computer‐aided modules available—indeed a search on Google gave over 1 million hits. Some modules are good but many are mediocre. What separates the gems from the trash?
