A firm may decide to have some of its customers sign exclusive contracts in order to deprive a rival of the minimum viable size, exclude it from the market, and enjoy increased market power. If contracts are required to be simple enough, this strategy may induce inefficient exclusion even if the...

This paper shows that dominant firms may wish to encourage competition in vertically-related markets. It shows that firms' incentives to vertically integrate other firms depends on the competitive environment.

This paper illustrates the effect of market size on the decision of whether or not firms should vertically integrate or disintegrate. We use a model of two successive stages of production with Cournot competition in each stage. In this model, firms choose to specialize (either upstream or...

This paper argues that an adequate approach to the firm should be able to accommodate the complexities of actual firm development. The latter is conceptualized in terms of three general stages: prime movers or drivers of change, change processes, and change attractors. Furthermore, any...

This paper presents evidence from three French VAT reforms showing that tax shifting on prices operates differently upwards and downwards. This may appear as a paradox when reading usual studies on price shifting. This paper puts forward two different asymmetric effects. The first one is linked...

We consider an oligopolistic industry including leveraged firms and unleveraged ones where firms are engaged in a sequential decision-making process. At the first stage of the game, a firm and her bank, considering the demand uncertainty and the distribution probability of the shock, evaluate a...

Clean technologies implemented by polluters subject to environmental regulation are often developed and patented by specialized technology suppliers. This paper investigates the impact of the environmental regulation stringency on the diffusion of patented clean technologies when the polluters...
