• Agendas in legislative decision-making 

    Horan, Sean (Université de Montréal. Département de sciences économiques., 2016-02)
    Despite the wide range of agendas used in legislative decision-making, the literature has focused almost exclusively on two stylized formats, the so-called Euro-Latin and Anglo-American agendas. As emphasized by Ordeshook and Schwartz [1987], this focus ...
  • Positively responsive collection choice rules and majority rule: a generalization of May's theorem to many alternatives 

    Horan, Sean; Osborne, Martin J.; Sanver, M. Remzi (Université de Montréal. Département de sciences économiques., 2018-04)
    A collective choice rule selects a set of alternatives for each collective choice problem. Suppose that the alternative ’x’, is in the set selected by a collective choice rule for some collective choice problem. Now suppose that ‘x’ rises above another ...
  • Precision may harm: The comparative statics of imprecise judgement 

    Horan, Sean; Manzini, Paola (Université de Montréal. Département de sciences économiques., 2018-08)
    We consider an agent whose information about the objects of choice is imperfect in two respects: first, their values are perceived with ‘error’; and, second, the realised values cannot be discriminated with absolute ‘precision’. Reasons for imprecise ...
  • Random consideration and choice: A case study of «default» options 

    Horan, Sean (Université de Montréal. Département de sciences économiques., 2018-11)
    A growing number of stochastic choice models include a “default” option for situations where the decision maker selects none of the feasible alternatives. While this is a welcome development, these models also present an empirical challenge - since the ...
  • A simple model of two-stage choice 

    Horan, Sean (Université de Montréal. Département de sciences économiques., 2015-12)
    I provide choice-theoretic foundations for a simple two-stage model, called transitive shortlist methods, where choices are made by sequentially by applying a pair of transitive preferences (or rationales) to eliminate inferior alternatives. Despite ...
  • Threshold Luce rules 

    Horan, Sean (Université de Montréal. Département de sciences économiques., 2018-11)
    In the late 1950’s, Luce proposed two different theories of imperfect utility discrimination that have had a lasting impact on economics. One model (1956) gave rise to the literature on just noticeable differences while the other (1959) laid the ...
  • Two-stage majoritarian choice 

    Horan, Sean; Sprumont, Yves (Université de Montréal. Département de sciences économiques., 2020-05)
    We propose a class of decisive collective choice rules that rely on an exogenous linear ordering to partition the majority relation into two acyclic relations. The first relation is used to obtain a shortlist of the feasible alternatives while the ...
  • Welfare criteria from choice: the sequential solution 

    Horan, Sean; Sprumont, Yves (Université de Montréal. Département de sciences économiques., 2015-01)
    We study the problem of deriving a complete welfare ordering from a choice function. Under the sequential solution, the best alternative is the alternative chosen from the universal set; the second best is the one chosen when the best alternative is ...
