We analyze the competitive effects of bilateral cross-licensing agreements in a setting with many competing firms. We show that firms can sustain the monopoly outcome if they can sign unconstrained bilateral cross-licensing contracts. This result is robust to increasing the number of firms who can...

We provide a method allowing identification of margins in an oligopoly price competition game when prices may not be freely chosen in some markets, for example due to regulation. We use our identification strategy to study the effects of regulatory constraints in the pharmaceutical industry. We...

We study the ability of several identical firms to collude in the presence of a more efficient firm, which does not take part in their collusive agreement. The cartel firms adopt stick-and-carrot strategies, while the efficient firm plays its one-period best-response function, regardless of the...

Assessing the nonlinearity of the calorie-income relationship is a crucial issue when evaluating policies aimed at fighting against malnutrition. A natural choice would be to adopt a fully nonparametric speci- fication of the relationship in order to let the data reveal its nonlinearity. But, we...

There is widespread evidence that some firms use false advertising to overstate the value of their products. We consider a model in which a policy maker can punish such false claims. We characterize an equilibrium where false advertising actively influences rational buyers and analyze the effects...

This chapter estimates a dynamic reduced-form model of intra-firm promotions using an employer–employee panel of over 300 of the largest corporations in the United States in the period from 1981 to 1988. The estimation conditions on unobserved individual heterogeneity and allows for both an...

While the adverse climate and health impacts of the Western diet have been demonstrated, the place of fish/seafood in climate-friendly and healthy diets is unclear. We tackle that question with a model simulating how a rational consumer urged to consume more fish would modify his diet. Those...

We study the role and performance of private equity (PE) in corporate asset sales. Corporate sellers obtain significantly positive excess returns in PE deals, gains in wealth significantly greater than for intercorporate asset sales. Based on exit valuations for 98% of PE deals, we find gains in...

We focus on nonconvex and nonsmooth minimization problems with a composite objective, where the differentiable part of the objective is freed from the usual and restrictive global Lipschitz gradient continuity assumption. This longstanding smoothness restriction is pervasive in first order methods...

For an arbitrary finite family of semialgebraic/definable functions, we consider the corresponding inequality constraint set and we study qualification conditions for perturbations of this set. In particular we prove that all positive diagonal perturbations, save perhaps a finite number of them,...
