The impact of search costs on consumer behavior: A dynamic approach

Prices for grocery items differ across stores and time because of promotion periods. Consumers therefore have an incentive to search for the lowest prices. However, when a product is purchased infrequently, the effort to check the price every shopping trip might outweigh the benefit of spending less. I propose a structural model for storable goods that takes into account inventory holdings and search. The model is estimated using data on laundry detergent purchases. I find search costs play a large role in explaining purchase behavior, with consumers unaware of the price of detergent on 70 % of their shopping trips. Therefore, from the retailer’s point of view raising awareness of a promotion through advertising and displays is important. I also find a promotion for a particular product increases the consumer’s incentive to search. This change in incentives leads to an increase in category traffic, which from the store manager’s perspective is a desirable side effect of the promotion.     

The Selection of Distribution Channels in China

This contribution first traces the development of the distribution system in China from state monopoly to one which permits the limited participation of foreign ventures, and examines the problems faced by foreign investors in managing the distribution channels under such a transitional economy. Due to China's abundance of linguistic, cultural and economic differences, combined with growing territorialism at the provincial level, different problems may be encountered in different citieslregions, and therefore foreign investors need to modify their distribution strategies accordingly. Detailed case studies are provided as illustrations.     

A model for the influence of social interaction and social support on female expatriates' cross-cultural adjustment

This paper offers a model to describe the way in which female expatriates develop relationships and utilize those relationships to become cross-culturally adjusted. This model includes three predictive components affecting cross-cultural adjustment. The first includes the factors affecting whether a woman is able to form relationships on the expatriate assignment. These antecedents can include the female expatriate's personality, the cultural norms towards women, her language skills and the availability of possible opportunities for interaction. The second component includes the various sources of social interaction and social support (e.g. family members, and host national colleagues). The third component describes the nature of a female expatriate's social interaction and social support (e.g. emotional, informational and instrumental). Practical considerations for multinational organizations sending female expatriates are offered.     

‘I Don't Like My Children to Grow up in this Bad Area’: Parental Anxieties about Living in Informal Settlements

A growing body of research on informal settlements considers the experiences of children, but seldom outlines the daily parenting experiences of adult men and women. At the same time, policy on housing in South Africa points to the ways in which the ‘eradication’ of informal housing will help provide children with better futures. This article explores the social relation of parenting within an informal settlement in Durban, South Africa, bearing in mind the broader difficulties of parenting in poverty, and points to ways in which the material qualities of informal settlements contribute to feelings of anxiety in parents. It questions how these experiences might differ from or be similar to those of parents who live in generic contexts of poverty (but not necessarily informality). It concludes ultimately that living in an informal settlement does actually contribute to particular parental anxieties, but that there is no guarantee that informal housing eradication will remove these concerns.     

Interne Unternehmensberatungen

Ziel des vorliegenden Beitrags ist der Versuch, eine erste Systematisierung sowie eine Erweiterung und Aktualisierung der bestehenden Forschung über Formen sowie Funktionen Interner Unternehmensberatungen zu leisten. Auf Basis einer begriffsgeschichtlichen Ann?herung und der Rekonstruktion der wissenschaftlichen Beratungsforschung werden Ergebnisse einer empirischen Analyse eines kleinen Samples von Internen Beratungen vorgestellt. Vor dem Hintergrund dieses Datenmaterials formulieren die Autoren im zweiten Teil Thesen über aktuelle und potentielle Positionierungsszenarien von Internen Unternehmensberatungen. Hierbei steht insbesondere der Vergleich zu Externen Beratungen im Vordergrund.     

How Big is the Crowding-Out Effect of User Fees in the Rural Areas of Ethiopia? Implications for Equity and Resources Mobilization

Using a nested multinomial logit model, this study investigates the demand “reduction” and “diversion” effects of user fees in rural areas of Ethiopia. The results reveal that an increase in user fees of public clinics, which are the most widely used alternative, can have a significant demand reduction effect on the poorest of the poor. This implies that despite cost recovery has been advocated as an alternative means of health care financing in most of the developing world, increasing user fees may drive the poorest segment of the population out of the health care market unless some protective measures are taken.     

Inter-firm Collaboration and Learning: The Case of the Japanese Automobile Industry

This paper investigates the effect of intra-firm Research and Development expenditure and inter-firm collaboration on firm performance. It is proposed that R&D expenditures enable a company to improve knowledge and assimilate the exchange of information within non-routine collaboration activities. The hypotheses are tested by an empirical study on inter-firm technical collaboration in Japanese Automobile firms during the years 1975–1995, using the method of first-order auto-regression on a panel data set. The findings indicate that R&D expenditure increases performance, but do not allow clear conclusions on the effects of collaborations.     

A multiple dispatch and partial backup hypercube queuing model to analyze emergency medical systems on highways

The hypercube is a spatially distributed queuing model based on Markovian analysis approximations, used to analyze the configuration and operation of server-to-customer emergency systems. In the present study we adapted the model to analyze emergency medical systems (EMS) on highways, which operate within particular dispatching policies. The study takes into consideration that: the emergency calls are of different types; the servers are distinct (e.g., rescue ambulances, medical vehicles); only certain servers in the system can service calls in a given region (partial backup); and, depending on the type of call, one or more identical or distinct servers are immediately dispatched to service such calls (multiple dispatch). We also consider that the arriving calls take place either along the highway or at the home location of a server – in which case the server does not need to travel to the call location. Finally, we analyzed the computational results of applying such an approach to the case study of an EMS operating on Brazilian highways.     

Fairness and the employment contract: North American regions versus Germany

Substantial evidence shows that North Americans are generallymore accepting of the market than Europeans and attribute marketoutcomes to a larger degree to effort or skill. Thus, NorthAmericans might be more accepting of layoffs and pay cuts thanGermans, and Germans might be more sensitive to the proceduresand conditions under which pay cuts and layoffs occur. The empiricalresults from our quasi-experiment are largely in line with thesehypotheses. The results may help to explain and be explainedby the different labour market institutions in the differentregions.
