We examine a Bertrand competition game between two intermediaries offering matching services between two sides of a market. Indirect network externalities arise as the probability of finding one's match with a given intermediary increase with the number of agents of the other side who use the...

The Paper analyses the funding of an infrastructure project (high speed train line, platform, tunnel, harbor, regional airport, fibre-to-the-home network, etc.) in a situation in which an incumbent operator has private information about market profitability (demand, cost) and the infrastructure...

We develop an agency model of organized crime accounting for the main trade-offs involved by the introduction of an accomplice-witness program. We characterize the optimal policy and identify its main determinants in a framework where public officials can be dishonest. Our predictions are tested...

We study how career concerns affect the dynamics of incentives in a multi-period contract, when the agent’s productivity is a stochastic function of his past productivity and investment. We show that incentives are stronger and performance is higher when the contract approaches its expiry...

The paper discusses economic theories of harm for anti-competitive margin squeeze by unregulated and regulated vertically integrated firms. We review both predation and foreclosure theories, as well as the mere exploitation of upstream market power. We show that foreclosure provides an...

We develop a model of interlocking bilateral relationships between upstream firms (manufacturers) that produce differentiated goods and downstream firms (retailers) that compete imperfectly for consumers. Contract offers and acceptance decisions are private information to the contracting...

The paper revisits the conventional wisdom according to which vertical restrictions on retail prices help upstream firms to collude. We analyse the scope for collusion with and without resale price maintenance (RPM) when retailers observe local shocks on demand or retail costs. In the absence of...

This paper develops a general equilibrium model of technological adoption in an economy populated by 'satisficing' entrepreneurs whose main objective is to minimise innovative effort while keeping the firm alive. In such an economy, product market competition is shown to have a stimulating...

This paper develops an agency model in which firms can influence their own incentives to provide a non-contractible effort by contracting on other variables (e.g. by committing themselves to some verifiable investment). In such a model the firms' need for outside finance is shown to interact...
