The psychological contract in Chinese-African informal labor relations

This qualitative study analyzes Chinese-Ghanaian employment in trade as an example of South-South cross-cultural labor relations. Based on ethnographic fieldwork, employment practices and labor conflicts are discussed with regard to psychological contract and equity. The analysis is guided by a process model of psychological contract that has been adjusted and extended in consideration of the dimensions of foreignness and cross-cultural communication. After briefly introducing the situation in Ghana we elaborate that under conditions of foreignness, employment relations are conflict prone because of contradictory equity expectations of employers and employees. We discuss how Ghanaian employees perceiving their psychological contract as violated attempt to restore equity by means of voice, silence, retreat or destruction and often fail due to lack of mutual cultural understanding between employers and employees. We conclude that exit in contrast to expectations is a viable option for employers rather than employees, but most employment relations, though defective, are perpetuated.     

Food Industry Firms' Economic Incentives to Provide Nutritional Information to the Market: European Breakfast Cereals,Snacks, and Soft Drinks Industries

Information asymmetries between producers and consumers exist with respect to nutritional characteristics of foods and beverages. This article aims to analyze firms' methods to supply nutritional information, focusing on 3 specific food industries: breakfast cereals, snacks, and soft drinks. A theoretical model is developed and tested empirically on European firm-level data obtained from company websites. Firms' incentives to provide nutritional information are positively related to their products' healthfulness, to firm size, and to firms' degree of international orientation. These insights may have important implications for the design of regulations to increase efficiency in the supply of nutritional information to consumers.

The importance of spatial economics for assessing airport competition

This paper explores the relevance of spatial effects on airport competition. Drawing concentric circles of travel distances around it is the most commonly way to define an airport’s catchment area. The characteristics of the catchment area and available substitutes are compared, and assessments of market power made. It is generally recognized that the existence of spatial competition among airports, lies within one market, although sometimes, overlapping circles are examined on the premise that competition lies within these common areas. We look at economic models of spatial competition where there is no overlapping and argue that the stylized facts inferred from economic models of spatial competition have been overlooked. After a short review of airport competition, we introduce economic models for spatial competition and look at the implications of these in the context of airport competition.     

Chaos in German stock returns — New evidence from the 0-1 test

This paper applies the 0-1 test for chaos to returns from the German stock market, providing empirical evidence of chaotic structures in the returns of all DAX members. For noise reduction purposes, wavelet denoising is employed prior to the application of the 0-1 test.
