This paper analyses the optimal enforcement of competition policy against collusion under asymmetric information on cartel's costs and observable prices. The implementable price schedules are increasing, and the net profits decreasing, in cartel's costs, while expected penalties are increasing...

In this article we analyse the effects of different regulatory schemes (price cap and profit sharing) on a firm's investment of endogenous size. Using a real option approach in continuous time, we show that profit sharing does not affect a firm's start-up decision relative to a pure price cap...

In this paper we review and extend the theory of quality regulation and of self-regulation and try to see to what extent the present theoretical literature can help to direct the regulatory reform of Italian financial markets. In financial markets, several countries have heavily relied upon self...

Restructuring firms in a transition economy produces a sort of network externality, in that the profitability of restructuring depends on the number of firms that already adopted this strategy. We investigate under what conditions a ''critical mass'' exists, i.e. a situation in which such...

In this paper we analyse a common agency model in which agents can choose with how many principals they want to work, while principals cannot condition contracts on the agent's decision to accept other contracts. In this case of "non-intrinsic" common agency we characterise the equilibrium....

This paper shows that the introduction of a minimum quality standard can have repercussions on market structure, opening the possibility of predatory behaviour. The predatory equilibrium exists independently of whether or not adjustment costs are present. Moreover, whenever predation is an...

This paper provides an empirical analysis of GovernmentsÕ decisions to sell privatised companies on both international and domestic markets in a sample of 392 privatisations in 42 countries in the 1977-1998 period. Political theories of privatisation find strong support in our analyses: market...

This paper analyses in a hidden characteristic set-up the design of the optimal price for a firm which is a monopolist at home but competes abroad against foreign firms. As long as diseconomies of scope are not too strong, the optimal price is identified. The price rule depends on the sign of...

This paper investigates how the ownership and the procedure for the selection of firms operating in the local public transport sector affect their productivity. In order to compare different institutional regimes, we carry out a comparative analysis of 72 companies operating in large European...

We study the regulation of a firm which supplies a regulated service while also operating in a competitive, unregulated sector. If the firm conducts its activities in the two markets jointly, it enjoys economies of scope whose size is the firm's private information, unknown either to the...
