In this paper, we take a first step toward exploring empirically the product assortment strategies of oligopolistic firms. Our starting point is a discrete-choice demand model for differentiated products. We incorporate the demand model into an equilibrium supply model, in which firms compete by...

In this paper we study the emergence of firm asymmetry as an equilibrium outcome. We consider differentiated Cournot and Bertrand duopolies where firms endogenously select their organizational governance and their timing strategy for the market stage. It is shown that for both market structures...

The traditional argument that shorter product cycles favor trade secret over patenting is reviewed. A game theoretic model provides an argument that shorter product cycles can induce firms to file more patent applications. The firms may be trapped in a prisoners' dilemma where all firms would...

We provide a model of dynamic duopoly in which firms face financial constraints and disappear when they are unable to fulfill them. We show that, in some cases, Cournot outputs are no longer supported in equilibrium, because if these outputs were set, a firm may have incentives to ruin the...

A recent literature has emerged providing compelling evidence that a major shift in the organization of the developed economies has been taking place: away from what has been characterized as the managed economy towards the entrepreneurial economy. In particular, the empirical evidence provides...

A monopolist is treated as a nexus of contracts with team production. It has one ownermanager. The owner-manager is the employer of two employees. A team production problem is present if the employer is a managerial lemon. If the team production problem is solved, the employer is a managerial...

The formation of new firms is an important determinant of economic development and the industrial organization literature highlights agglomeration as one of the main factors affecting the formation and scale of operations of new firms. This paper is one of the first to use developing country...

Since the early 2000s, there has been rapid growth in the number and spread of supermarkets in southern Africa. This paper is a synthesis of key findings of studies undertaken in Botswana, South Africa, Zambia, and Zimbabwe on the expansion of supermarkets and the impact this has had on...

This paper explores the effect of the spread of supermarkets on the participation of suppliers in supermarket value chains in Botswana and South Africa. Using secondary data and in-depth interviews with key players in the value chain, the paper evaluates the buyer power of supermarkets evidenced...
