    • Asymmetric dominance, deferral and status quo bias in a behavioral model of choice 

      Gerasimou, Georgios (2016-02) - Journal article
      This paper proposes and axiomatically characterizes a model of choice that builds on the criterion of partial dominance and allows for two types of avoidant behavior: *choice deferral* and *status quo bias*. These phenomena ...
    • A behavioural model of choice in the presence of decision conflict 

      Gerasimou, Georgios (University of St Andrews, 2013-05) - Working or discussion paper
      This paper proposes a model of choice that does not assume completeness of the decision maker’s preferences. The model explains in a natural way, and within a unified framework choice when preference-incomparable options ...
    • A characterization of risk-neutral and ambiguity-averse behavior 

      Gerasimou, Georgios (University of St Andrews, 2015-12-09) - Working or discussion paper
      This paper studies a decision maker who chooses monetary bets/investment portfolios under pure uncertainty. Necessary and sufficient conditions on his preferences over these objects are provided for his choice behavior to ...
    • Choice, deferral and consistency 

      Costa-Gomes, Miguel; Cueva, Carlos; Gerasimou, Georgios (University of St Andrews, 2014-12-26) - Working or discussion paper
      In this paper we study decision making in situations where the individual's preferences are not assumed to be complete. First, we identify conditions that are necessary and sufficient for choice behavior in general domains ...
    • Dominance solvable games with multiple payoff criteria 

      Gerasimou, Georgios (University of St Andrews, 2014-07-25) - Working or discussion paper
      Two logically distinct and permissive extensions of iterative weak dominance are introduced for games with possibly vector-valued payoffs. The first, iterative partial dominance, builds on an easy-to-check condition but ...
    • Dominance solvable multicriteria games with incomplete preferences 

      Gerasimou, Georgios (2018-11-08) - Journal article
      This paper studies dominance solvability in games with multidimensional payoffs and incomplete preferences. The main result offers a generalization of Moulin’s (Econometrica 47:1337–1351, 1979) classic equilibrium-selection ...
    • (Hemi)Continuity of additive preference preorders 

      Gerasimou, Georgios (2015-05) - Journal article
      It is shown that the two common notions of topological continuity for preference preorders, which require closed contour sets and a closed graph respectively, are equivalent even when completeness is not assumed, provided ...
    • Indecisiveness, undesirability and overload revealed through rational choice deferral 

      Gerasimou, Georgios (2018-09) - Journal article
      Three reasons why decision makers may defer choice are indecisiveness between various feasible options, unattractiveness of these options, and choice overload. This paper provides a choice-theoretic explanation for each ...
    • On the indifference relation in Bewley preferences 

      Gerasimou, Georgios (2018-03) - Journal article
      Bewley’s (2002) influential model of preferences over uncertain prospects features an incomplete preference relation and a set of priors over the states of the world such that one act is preferred to another if and only ...
    • Partially dominant choice 

      Gerasimou, Georgios (2016-01) - Journal article
      This paper proposes and analyzes a model of context-dependent choice with stable but incomplete preferences that is based on the idea of partial dominance: An alternative is chosen from a menu if it is not worse than ...
    • Prest: open-source software for computational revealed preference analysis 

      Gerasimou, Georgios; Tejiscak, Matus (2018-10-21) - Journal article
