Electoral Thresholds as Coordination Devices
Nunez, Matias; Xefteris, Dimitrios (2017)In this paper, we study one-person–one-vote parliamentary elections where voters care both about the winner of elections and about the composition of the parliament. Parties enter the parliament if and only if their vote ...

Enforcement actions on banks and the structure of loan syndicates
Delis, Manthos D.; Iosifidi, Maria; Kokas, Sotirios; Xefteris, Dimitrios; Ongena, Steven (2020)We investigate the effect of regulatory enforcement actions on banks' reputation by estimating the effect of non-compliance with laws and regulations among lead arrangers on the structure of syndicated loans. Consistent ...

Equilibria in unidirectional spatial models
Xefteris, Dimitrios (2013)This paper (a) characterizes the unique Nash equilibrium of the unidirectional Hotelling-Downs game in which firms maximize their market shares, for any distribution of the consumers, and (b) analyzes equilibrium behavior ...

Equilibrium in a discrete Downsian model given a non-minimal valence advantage and linear loss functions
Xefteris, Dimitrios (2013)This note complements Aragonès and Palfrey [Aragonés, E., Palfrey, T., 2002. Mixed strategy equilibrium in a Downsian model with a favored candidate. Journal of Economic Theory 103, 131-161.] and Hummel [Hummel, P., 2010. ...

Formalizing Happiness
Xefteris, Dimitrios (2012)The level of happiness of an individual who accepts the consequences of authoritative policy decisions is a clearly different concept from the utility that is delivered to the same individual by these policies and it depends ...

Hotelling was right
Xefteris, Dimitrios (2013)This paper proves existence of a subgame perfect equilibrium in Hotelling's original (unidimensional city, linear transportation costs, uniform distribution of the consumers, two firms with identical and constant marginal ...

Article
How robust is majority voting as a social choice rule?
Xefteris, Dimitrios (2014)This article strengthens existing analysis concerning the effectiveness of majority rule. It demonstrates a one-to-one equivalence between the basic issue of social choice theory (the problem of selection of a well-functioning ...

Article
Imperfectly informed voters and strategic extremism
Xefteris, Dimitrios; Aragonés, Enriqueta (2017)We analyze a two-candidate Downsian model considering that voters use shortcuts (e.g., interest-group/media endorsements) to infer candidates' policy platforms. That is, voters do not observe candidates' exact platforms ...

Article
Implementation via approval mechanisms
Nunez, Matias; Xefteris, Dimitrios (2017)We focus on the single-peaked domain and study the class of Generalized Approval Mechanisms (GAMs): First, players simultaneously select subsets of the outcome space and scores are assigned to each alternative

Article
Incomplete information, proportional representation and strategic voting
Troumpounis, Orestis; Xefteris, Dimitrios (2016)We introduce incomplete information to a multiparty election under proportional representation: each voter knows her preferences and votes strategically to maximize her payoffs, but is uncertain about the number and the ...

Institutions of direct democracy and happiness : the effect of decision making institutions on individual and social happiness, theory and experimental evidence

Article
Mixed equilibria in runoffelections
Xefteris, Dimitrios (2014)We demonstrate that the Hotelling-Downs model with runoffvoting always admits symmetric mixed strategy equilibria for any (even or odd) number of office-motivated candidates (provided they are at least four). In specific, ...

Article
Mixed equilibriums in a three-candidate spatial model with candidate valence
Xefteris, Dimitrios (2014)We study a spatial model of electoral competition among three office-motivated candidates of unequal valence (one advantaged and two equally disadvantaged candidates) under majority rule assuming that candidates are uncertain ...

Article
Mixed strategy equilibrium in a Downsian model with a favored candidate: A comment
Xefteris, Dimitrios (2012)This note complements Aragonès and Palfrey (2002) [2] by providing upper and lower bounds of the equilibrium payoff of the advantaged (disadvantaged) candidate for any symmetric distribution of the median voter's ideal ...

Article
Multidimensional electoral competition between differentiated candidates
Xefteris, Dimitrios (2017)It is known that multidimensional Downsian competition fails to admit an equilibrium in pure strategies unless very stringent conditions on the distribution of voters' bliss points are imposed (Plott, 1967). This paper ...

The necessary and sufficient condition for the transitivity of the Majority Rule in the linear domain
