The "spokes model" takes the name from its graphical visualisation, that resembles the spokes of a bike's wheel. It describes a market as a collection of spokes, joining at a common centre, where consumers are located. Firms may be situated at the extreme of these spokes, at the interior of the...

Outsourcing decisions by organizations have strategic and operational implications. Strategically, understanding the market and competition is necessary to make effective outsourcing decisions. In this paper we recognize this concern and model the situation where an organization with quality and...

We study the impact of the urban location of one single public facility on spatial competition agrave; la Hotelling. If transportation costs are very low compared to the value of the public service then both firms tacitly choose the facility location without moderation of price competition, in...

In this paper, I assume the existence of distribution of urbanamenities having its maximum at the city center. These amenities are viewed as a surrogate for all kinds of outside opportunities taht consumers encounter within urban areas. Using the Hotelling model, I study the impact of these...

We analyze the location of final goods producers under spatial competition with strategic input price determination by firm-specific input suppliers when the final goods producers undertake complete outsourcing or bi-sourcing. Under complete outsourcing, the final goods producers locate closer...

Many oligopoly theories predict that there will be a positive correlation between market size and the equilibrium number of firms, and some also imply that competition is more intense in larger markets. We test these predictions with a sample of 535 driving schools in 249 markets. With an...

The empirical literature on mergers, market power and collusion in differentiated markets has mainly focused on methods relying on output and/or panel data. In contrast to this literature we suggest a novel approach that allows for the detection of collusive behaviour among a group of firms...
