We investigate the relationship between market concentration and industry innovative effort within a familiar two-stage model of R&D race in which firms compete à la Cournot in the product market. With the help of numerical simulations, we show that such a setting is rich enough to generate...

In this paper, we provide a very simple model to shed light on the issue of managed competition in mixed quasi-markets (i.e. regulated markets in which social and for-proÖt Örms coexist). In doing this, we consider the literature on mixed oligopolies as a reasonable reference point and try to...

We investigate how cooperative firms reacted to the current crisis. This allows us to compare the behavior of cooperative and conventional firms facing exogenous shifts in demand. After a short survey of a stream of theoretical literature, we analyze a large group of Italian production...

We charaterise the socially optimal mix of firms in an oligopoly with both profit-seeking and labour-managed firms. The policy maker faces a twofold externality: (i) production entails the exploitation of a common pool natural resource and (ii) production/consumption pollutes the environment. We...

We study the incentives towards horizontal merger among firms when the amount of capital is the strategic variable. The type of firms we focus on is workers' cooperatives, but our conclusions apply also to employment-constrained profit maximisers. Within a simple oligopoly model, we prove that...

Within a simple model of differentiated oligopoly, we show that tacit collusion may be prevented by the threat of nationalising a private firm coupled with the appropriate choice of the weight given to private profits in the maximand of the nationalised company. We characterise the properties of...

Within a simple model of homogeneous oligopoly, we show that the traditional ranking between Bertrand and Cournot equilibria may be reversed. For price setting entails a continuum of price equilibria under convex variable costs, departure from marginal cost pricing may be observed. As a...

We show that the standard argument according to which supply function equilibria rank intermediate between Bertrand and Cournot equilibria may be reversed. We prove this result within a static oligopolistic game in which both supply function competition and Cournot competition yield a unique...

This paper aims at participating in the long-lasting debate about the analytical foundations of the Cournot equilibrium. In a homogeneous oligopoly, under standard regularity conditions, we prove that Cournot-Nash emerges both under (i) price competition and Cournot conjectures; and (ii) supply...

We show that supply functions cannot be classified as either strategic complements or substitutes according to the twofold criterion advanced by Bulow et al. (1985). This is because while the slope of the best reply is univocally positive, this is not the case with the sign of the cross...
