I study how firms actually compete in nonlinear tariffs by analyzingwhether the incumbent and entrant's decisions to offer a given number oftariff options are interrelated. The goal is to shed some light on thosedynamic and strategic aspects of tariff menus that are currently ignoredby...

This paper explores the role of trade integrationor opennessfor monetary policy transmission in a medium-scale New Keynesian model. Allowing for strategic complementarities in price-setting, we highlight a new dimension of the exchange rate channel by which monetary policy directly impacts...

A principal offers bilateral contracts to a set of agents organized in a network conveying synergies, in a context where agents' efforts are observable and where the principal's objective increases with the sum of efforts. We characterize optimal contracts as a function of agents' positions on...

When there is strategic complementarity of consumption between neighbors in a social network, we find that certain consumers may have a bigger impact than other consumers on the market demand and therefore the equilibrium price. The influence that a particular consumer has on the market demand...

Intuitively, we might think that a multiproducts company which has the possibility to forecast the structure of demand does not need to protect itself against risks of stock shortages due to the variability of the characteristics of demand since this becomes foreseeable. Symmetrically, it seems...

We consider agents playing a linear network game with strategic complementarities. We analyse the problem of a policy maker who can change the structure of the network in order to increase the aggregate efforts of the individuals and/or the sum of their utilities, given that the number of links...

We consider a common investment project that is vulnerable to a self-fulfilling coordination failure and hence is strategically risky. Based on their private information, agents { who have heterogeneous investment incentives - form expectations or "sentiments" about the project's outcome. We...

This paper explores the role of trade integration—or openness—for monetary policy transmission in a medium-scale New Keynesian model. Allowing for strategic complementarities in price-setting, we highlight a new dimension of the exchange rate channel by which monetary policy directly impacts...
