Choice, preference and rationalizability in pareto’s theory of economic behavior

Pareto initiated the shift of economic theory from utility/preference to choice in order to fill a gap between theoretical and empirical economics. His suggestions for an empirically-oriented theory of choice were to be developed decades later in the literature on revealed preference and on the conditions of equivalence between preference-based and choice-based axiomatic structures. In the process, however, substantial departures from Pareto’s implicit design of the situation of choice were introduced. In this paper, the conditions for the rationalizability of choice are re-defined so that they fit the type of situation that Pareto had in mind. The result is that the main consistency axioms of standard choice theory have to give way to a different combination of axioms that concern decisiveness as well as consistency.

Partnership,reciprocity and team design

This paper studies the effect of intention-based reciprocity preferences on the free-riding problem arising in partnerships. Our results suggest a tendency of efficient partnerships to consist of members whose sensitivity to reciprocity is – individually or jointly – sufficiently high. Sufficient conditions for the implementation of the efficient strategy profile require a reciprocity-based sharing rule so that each partner gets a fraction of the output, which is a percentage of his own sensitivity to reciprocity with respect to the overall sensitivity in the team. Finally, we introduce the concept of psychological strong Nash equilibrium and show that it allows for the unique and collusion-proof implementation of the efficient strategy profile.     

Evaluating the median voter model’s explanatory power

We match individual senators’ voting behavior on legislative proposals with 24 real referendum decisions on exactly the same issues with identical wording. This setting allows us to evaluate the median voter model’s quality with revealed constituents’ preferences. Results indicate a limited explanatory power of the median voter model: It explains 17.6% points more than random voting and that a senator’s probability to accept a proposal in parliament increases on average by 8.4% points when the district median voter accepts the proposal.     

Sequential voting with abstention

Dekel and Piccione [2000. Sequential voting procedures in symmetric binary elections. J. Polit. Economy 108, 34–55] have proven that information cascades do not necessarily affect the properties of information aggregation in sequential elections: under standard conditions, any symmetric equilibrium of a simultaneous voting mechanism is also an equilibrium of the correspondent sequential mechanism. We show that when voters can abstain, these results are sensitive to the introduction of an arbitrarily small cost of voting: the set of equilibria in the two mechanisms are generally disjoint; and the informative properties of the equilibrium sets can be ranked. If an appropriate q-rule is chosen, when the cost of voting is small the unique symmetric equilibrium of the simultaneous voting mechanism dominates all equilibria of the sequential mechanism.     

Who benefits from privileged peers? Evidence from siblings in schools

By comparing siblings attending the same school at different points in time, we investigate whether the effect of peer quality on long-term labor market outcomes varies with parental background. We find that exposure to better peers—who have higher mean parental education—increases lifetime earnings of disadvantaged students, coming from families with low parental education, but penalizes privileged students from better educated families. These results suggest that desegregation policies that allocate disadvantaged students to schools with better peers produce long-term benefits. We discuss mechanisms and show that human capital accumulation, ordinal rank and network effects contribute to explain our findings.     

Mix between Satisfaction and Attributes Destination Choice: A Segmentation Criterion to Understand the Ski Resorts Consumers

This study examined the attributes prioritized by tourists when choosing a winter sports destination and their degree of satisfaction with the services provided by Portugal's only ski resort. Two hundred tourists completed a questionnaire with factor analysis then deployed to extract the data that served as the basis for cluster analysis. Our results report discrepancies between the attributes valued by tourists when choosing winter sports destinations and their degree of satisfaction with the ski resort's services. Moreover, the combination between attributes/motivations prevailing in destination selection and the subsequent satisfaction with the services provided may generate information of relevance to evaluating organizational competitiveness.

News shocks or parametric indeterminacy? An observational equivalence result in linear rational expectations models

This paper studies identification in linear rational expectations models with news shocks. We show that news-driven models and indeterminate equilibrium economies with i.i.d. fundamentals are observationally equivalent. This finding calls for carefully designing empirical investigations of news shocks in estimated DSGE models.     

Interactive identity work of professionals in management: a hospital case study

ABSTRACT

Hybrid professional managers appear less effective in introducing management into public professional settings than policymakers hope. To date, research has offered little understanding of professionals’ identity transition challenge and the role of social interactions underpinning this process. We studied the identity work of hybrid doctors inside a large public health-care organization, finding that it takes place through processes of familiarizing with management, rationalizing being a hybrid, and legitimizing the new role-identity. We contribute to the literature by showing that identity work is distributed and enabled by social interactions beyond the professional group. Implications for policymakers and executives are discussed.
