We study a psychologically based foundation for choice errors. The decision maker applies a preference ranking after forming a 'consideration set' prior to choosing an alternative. Membership of the consideration set is determined both by the alternative specific salience and by the rationality...

We propose an extension of Tversky's lexicographic semiorder to a model of boundedly rational choice. We explore the connection with sequential rationalisability of choice, and we provide axiomatic characterisations of both models in terms of observable choice data.

We document a large and persistent anomaly in the UK car insurance market over the period 2012-13: insurance companies charged a higher premium for third-party (liability) insurance than comprehensive insurance (which includes third-party). Furthermore, some companies charged higher prices for...

In this paper we investigate how cognitive ability and character skills influence behavior, success and the evolution of play towards Nash equilibrium in repeated strategic interactions. We study behavior in a p-beauty contest experiment and find striking differences according to cognitive...

This paper tests an intervention aimed at facilitating (cognitively) the adoption of healthy dietary habits. We provide easy-to-understand information about the risks of developing diabetes or heart diseases and give easy-to-follow dietary recommendations to minimize these risks. We implement...

Many decision models in marketing science and psychology assume that a consumer chooses by proceeding sequentially through a checklist of desirable properties. These models are contrasted to the utility maximization model of rationality in economics. We show on the contrary that the two...

A sequentially rationalizable choice function is a choice function which can be obtained by applying sequentially a fixed set of asymmetric binary relations (rationales). A Rational ShortlistMethod (RSM) is a choice function which is sequentially rationalizable by two rationales. These concepts...

In this paper we question the hypothesis of full rationality in the context of job changing behavior, via simple econometric explorations on microdata drawn from WHIP (Worker Histories Italian Panel). A rational outcome of the job matching process implies a positive tradeoff between future wages...

We survey samples of German firms and households to document novel stylized facts about the extent of information frictions among the two groups. First, firms' expectations about macroeconomic variables are closer to expert forecasts and less dispersed than households', consistent with higher...

Prominent economic theories have emphasized the role of commonly held perceptions and expectations for determining macroeconomic outcomes. A key empirical question is how such collectively held beliefs are formed. We use the FIFA World Cup 2006 as a natural experiment. We provide direct evidence...
