A planner can shape incentives in pursuit of an aggregate goal, such as maximizing welfare or minimizing volatility. We analyze a variety of targeting problems ...
Title:Can there be a market for cheap-talk information? : some experimental evidence Author(s):CABRALES, Antonio; FERI, Francesco; GOTTARDI, Piero; MELÉNDEZ-JIMÉNEZ, Miguel A.Date:2016Type:Working PaperSeries/Number:EUI ECO; 2016/07Abstract:This paper reports on experiments testing the viability of markets for cheap talk information. We find that these markets are fragile. The reasons are surprising given the previous experimental results on cheap-talk games. ...
Title:Characterization and uniqueness of equilibrium in competitive insurance Author(s):FARINHA LUZ, VitorDate:2015Type:Working PaperSeries/Number:EUI MWP; 2015/15Abstract:This paper provides a complete characterization of equilibria in a game-theoretic version of Rothschild and Stiglitz (1976)’s model of competitive insurance. I allow for stochastic contract offers by insurance firms and ...

We experimentally examine the impact of tax evasion attempts on the performance ...
Title:Risk-sharing and contagion in networks Author(s):CABRALES, Antonio; GOTTARDI, Piero; VEGA-REDONDO, FernandoDate:2013Type:Working PaperSeries/Number:EUI ECO; 2013/01Abstract:The aim of this paper is to investigate how the capacity of an economic system to absorb shocks depends on the specific pattern of interconnections established among financial firms. The key trade-off at work is between ...
Title:The Structure of the Lattices of Pure Strategy Nash Equilibria of Binary Games of Strategic Complements Author(s):RODRIGUEZ BARRAQUER, TomasDate:2012Type:Working PaperSeries/Number:EUI MWP; 2012/24Abstract:It has long been established in the literature that the set of pure strategy Nash equilibria of any binary game of strategic complements among a set N of players can be seen as a lattice on the set of all subsets of N under ...
Title:The Pro-Competitive Effect of Campaign Limits in Non-Majoritarian Elections Author(s):IARYCZOWER, Matias; MATTOZZI, AndreaDate:2012Citation:Economic Theory, 2012, 49, 3, 591-619Type:ArticleAbstract:We study a model of elections in non-majoritarian systems that captures the link between competition in policies and competition in campaign spending. We argue that the overall competitiveness of the political arena depends ...
Title:Envy can promote more equal division in alternating-offer bargaining Author(s):KOHLER, StefanDate:2012Type:Working PaperSeries/Number:EUI ECOAbstract:Bargainers in an open-ended alternating-offer bargaining situation may perceive envy, a utility loss caused by receiving the smaller share that is modeled in some social preferences in addition to self-interest. I extend ...
Title:Natural Resource Distribution and Multiple Forms of Civil War Author(s):MORELLI, Massimo; ROHNER, DominicDate:2010Type:Working PaperSeries/Number:EUI ECO; 2010/33Abstract:We examine how natural resource location, rent sharing and fighting capacities of different groups matter for ethnic con.ict. A new type of bargaining failure due to multiple types of potential conflicts (and hence multiple ...
Title:Strategic Mass Killings Author(s):ESTEBAN, Joan; MORELLI, Massimo; ROHNER, DominicDate:2010Type:Working PaperSeries/Number:EUI ECO; 2010/23Abstract:Since World War II there have been about fifty episodes of large-scale mass killings of civilians and massive forced displacements. They were usually meticulously planned and independent of military goals. We provide a ...
Title:Markets for Information: Of Inefficient Firewalls and Efficient Monopolies Author(s):CABRALES, Antonio; GOTTARDI, PieroDate:2009Type:Working PaperSeries/Number:EUI ECO; 2009/11Abstract:In this paper we study, within a formal model, market environments where information is costly to acquire and is of use also to potential competitors. Agents may then sell, or buy, reports over the information acquired and ...
