In a real option model, we show that the standard analysis of vertical relationships transposes directly to investment timing. Thus, when a firm undertaking a project requires an outside supplier (e.g., an equipment manufacturer) to provide it with a discrete input to serve a growing but...

Collusion sustainability depends on firms' aptitude to impose sufficiently severe punishments in case of deviation from the collusive rule. We characterize the ability of oligopolistic firms to implement a collusive strategy when their ability to punish deviations over one or several periods...

This paper studies a liberalized postal market where entrants may offer end-to-end products or concentrate on one of the segments of the network. Absent effective bypass, entry does not appear to be a serious financial threat to the incumbent, even when the products are perfect substitutes. This...

We argue for the creation of a carbon liabilities market to address climate change. Each period, countries would be made liable for their share of responsibility in current climate damage. Because liabilities could be traded like financial debt, robustness to strategic manipulations and...

We build on Mason and Weeds’ (2010) model of duopoly investment under uncertainty by allowing high initial values of the profit shock as in Huisman and Kort (1999). Persistent first-mover advantage increases the likelihood of immediate simultaneous investment. In contrast with previous models...

This paper studies the price structure in a postal sector with a monopolistic operator when customers can engage in worksharing. It presents simulation results obtained from an empirical model that is calibrated on data from the French postal sector. The optimal worksharing discount is...
