Perfect competition and optimal product differentiation

This paper considers whether a competitive economy will achieve an optimal allocation when firms produce differentiated products.In the model studied, firms market those products which maximize profit given the demand curves facing them. Markets are assumed to be open only for goods actually traded. Competitive conditions are achieved by replicating the consumer sector. It is shown that market equilibrium may be suboptimal if those products not being produced are highly complementary in consumption. Sufficient conditions on preferences and production sets for the market equilibrium to be optimal are given.     

Asymptotic value of games with a continuum of players

We investigate the asymptotic value for a class of non-atomic games, which includes all those arising from markets with a continuum of traders. The main result is the following: the asymptotic value, if it exists, is the center of symmetry of the core. This implies that the value is a member of the core, and it gives a necessary condition for its existence. The sufficiency of this condition for the existence of the value is also studied.     

An Analysis of Product Deletion Scenarios

Despite a flurry of attention during the early 1980s and the occasional article thereafter, product deletion continues to suffer from neglect, which is surprising given its role in aiding processes of innovation and change that are central to competitive survival. The aim of this article is to rejuvenate research interest in this field. In doing so, we review and organize the relevant literature in three key sets of factors and postulate that their interplay delineates the product deletion scenarios followed by a company. On the basis of this argument, we develop a typology of product deletions and outline how it increases our knowledge of this critical issue and leads to useful research directions.     

Environmental Respect: Ethics or Simply Business? A Study in the Small and Medium Enterprise (SME) Context

In recent years there have been ever-growing concerns regarding environmental decline, causing some companies to focus on the implementation of environmentally friendly supply, production and distribution systems. Such concern may stem either from the set of beliefs and values of the company’s management or from certain pressure exerted by the market – consumers and institutions – in the belief that an environmentally respectful management policy will contribute to the transmission of a positive image of the company and its products. Sometimes, however, ethics and market rules are not enough to deal with this situation and specific laws must be considered. This is the case when companies base their activity on the ‹ethics of self-interest’ concentrating their efforts on projecting an adequate image – e.g. environmental respect – rather than fundamentally behaving in environmentally respectful ways. This article, taking as reference the SME context, discusses the reasons for implementing environmentally friendly systems. Both ethics and business seem to be relevant and, therefore, a certain balance between market and interventionism seems to be necessary.     

Founder nativity,founding team formation,and firm performance in the U.S. high-tech sector

This paper is motivated by the movement of foreign-born entrepreneurs out of ethnic enclaves and into the mainstream, globally-connected economies of the countries of immigration, and from necessity to opportunity entrepreneurship. The theoretical contribution of the paper is to integrate the emerging literature on foreign-born entrepreneurship with work on the composition and impact of founding teams. Empirically, we draw on original quantitative and qualitative data on the U.S. high-tech sector. We find that homophily drives team formation and that nationality diversity in founding teams has a modest impact on firm performance.     

Managing information sharing and stewardship for public-sector collaboration: a management control approach

Information sharing is essential for public-sector collaboration but needs to be balanced with information stewardship obligations. There is little research on how public-sector managers can influence the attitudes and behaviours of their employees to achieve these competing objectives. To investigate this, the study applies a management control framework to a case study of a law enforcement organization attempting to improve its information sharing and stewardship. The study extends prior literature by providing insights into the specific effects that different management controls have for the information sharing and stewardship behaviours of employees involved in public-sector collaboration.
