This paper investigates why women’s self-employment rates are consistently lower than those of men. It has three focal points. It discriminates between the preference for self-employment and actual involvement in self-employment using a two (probit) equation model. It makes a systematic...

In this note we review some known minimax theorems with applications in game theory and show that these results form an equivalent chain which includes the strong separation result in finite dimensional spaces between two disjoint closed convex sets of which one is compact. By simplifying the...

Research into the management of interorganizational relationships has hitherto primarily focused on problems of coordination, control and to a lesser extent, legitimacy. In this article, we assert that partners cooperating in such relationships are also confronted with ‘problems of...

Dividing forecasts of brand sales by a forecast of category sales, when they are generated from brand specific sales-response models, renders biased forecasts of the brands' market shares. In this paper we therefore propose an easy-to-apply simulation-based method which results in unbiased...

The development of economic thought is not unlike the development of technological knowledge: paradigms can be discerned over time and across the field. Indeed, in its history economics has experienced paradigm shifts. There is no reason why it will not do so again in the future. In technology,...

Existing studies of supplier involvement in new product development have mainly focused on project-related short-term processes and success-factors. This study validates and extends an existing exploratory framework, which comprises both long-term strategic processes and short-term operational...

The number of (registered) commercial banks in Russia increased at a fast pace after the 1988 banking reform. Many of these banks lacked supervision and operated with dangerously low funding capital. In this paper we investigate the determinants of the hazard rates of banks active on the...

Modular decomposition is a thoroughly investigated topic in many areas such as switching theory, reliability theory, game theory and graph theory. Most appli- cations can be formulated in the framework of Boolean functions. In this paper we give a uni_ed treatment of modular decomposition of...

With the emergence of smart business networks, agile networks, etc. as important research areas in management, for all the attractiveness of these concepts, a major issue remains around their design and the selection rules. While smart business networks should provide advantages due to the quick...

Public concern nowadays is an important frame of reference for the development of agricultural production systems. The development of such systems, therefore, involves both society level and production system level. Following Zadeh's principle of incompatibility, information obtained at...
