  • ​Afriat's Theorem and Samuelson's 'Eternal Darkness' 

    Polisson, Matthew; Renou, Ludovic (2016-08) - Journal article
    Suppose that we have access to a finite set of expenditure data drawn from an individual consumer, i.e., how much of each good has been purchased and at what prices. Afriat (1967) was the first to establish necessary and ...
  • Choice by lexicographic semiorders 

    Manzini, Paola; Mariotti, Marco (2012-01) - Journal article
    In Tversky’s (1969) model of a lexicographic semiorder, a preference is generated via the sequential application of numerical criteria by declaring an alternative x better than an alternative y if the first criterion that ...
  • Inferring cognitive heterogeneity from aggregate choices 

    Dardanoni, Valentino; Manzini, Paola; Mariotti, Marco; Tyson, Christopher J. (University of St Andrews, 2017-05-25) - Working or discussion paper
    We study the problem of recovering the distribution of cognitive characteristics in a popula-tion of boundedly rational agents from the aggregate choices they make from a fixed menu of alternatives. Two models of limited ...
  • A lattice test for additive separability 

    Polisson, Matthew (University of St Andrews, 2018-02-12) - Working or discussion paper
    We derive necessary and sufficient conditions for a finite data set of price and demand observations to be consistent with an additively separable preference. We do so without imposing concavity on any of the subutility ...
  • Satisficing choice procedures 

    Papi, Mauro (2012-09) - Journal article
    Standard choice theory assumes that the budget set is known to the decision-maker in advance. In contrast, we develop a model in which alternatives are examined sequentially and decision-makers exhibit `satisficing' ...
  • Two-stage threshold representations 

    Manzini, Paola; Mariotti, Marco; Tyson, Christopher (2013-09) - Journal article
    We study two-stage choice procedures in which the decision maker first preselects the alternatives whose values according to a criterion pass a menu-dependent threshold, and then maximizes a second criterion to narrow the ...
