We study a three-tier hierarchy Political Principal - Competition Authority - Firms in which the Principal chooses the Authority's (i) budget, (ii) percentage of the fine (bonus), and (iii) preferences in presence of moral hazard. Collusion between the Authority and firms may arise in order to...

L'exposé de séminaire sera divisé en deux parties. La première partie, plus générale et abstraite, traitera de la relaxation (par convexification), d'un problème variationel non convexe. On montrera comment on peut récupérer les solutions du problème relaxé à l'aide non pas des solutions du...

We obtain analytical expressions for the score of conditionally heteroskedastic dynamic regression models when the conditional distribution is elliptical. We pay special attention not only to the Student t and Kotz distributions, but also to flexible families such as discrete scale mixtures of...

We present an algorithm to compute the set of perfect public equilibrium payoffs as the discount factor tends to one for stochastic games with observable states and public (but not necessarily perfect) monitoring when the limiting set of (long-run players’) equilibrium payoffs is independent of the...

We show that deviations from long-run stability of product prices are optimal in the presence of endogenous producer entry and product variety in a sticky-price model with monopolistic competition in which price stability would be optimal in the absence of entry. Specifically, a long-run positive (...

In this seminar, we present a model for optimal transport with congestion effects: we will address both the discrete and the continuous case. From an individual viewpoint, we can introduce in a natural way a kind of Nash equilibrium, which in this context is usually called Wardrop equilibrium. Then...

We model the link between inequality and excessive risk taking. In the presence of increasing returns to tax avoidance, the middle class is willing to take non rewarded financial risk despite risk aversion. Electoral pressure may lead an incumbent politician to endorse this excessive risk taking if...
