In a social choice model with an infinite number of agents, there may occur “equal size” coalitions that a preference aggregation rule should treat in the samemanner.We introduce an axiom of equal treatment with respect to ameasure of coalition size and explore its interaction with common axioms of social choice. We show that, provided the measure space is sufficiently rich in coalitions of the...

Ontological analyses have been used in numerous publications to compare existing modelling grammars with an Ontology. Each analysis showed certain deficits of the modelling grammar. Consequently, improvements to these modelling grammars have been proposed. Most ontological analyses, however, are not based on a sound theoretical framework. This theoretical lack renders the results of these analy...

We report on laboratory experiments on voting. In a setting where subjects have single-peaked preferences, we find that the rational choice theory provides very good predictions of actual individual behavior in one-round and approval voting elections but fares poorly in explaining vote choice under two-round elections. We conclude that voters behave strategically as far as strategic computation...

Because most conjoint studies are conducted in hypothetical situations with no consumption consequences for the participants, the extent to which the studies are able to uncover “true” consumer preference structures is questionable. Experimental economics literature, with its emphasis on incentive alignment and hypothetical bias, suggests that more realistic incentivealigned studies will result...

This paper develops a new likelihood-based method for the simultaneous estimation of structural demand-and-supply models for markets with differentiated products. We specify an individual-level discrete choice model of demand and derive the supply side assuming manufacturers compete in prices. The proposed estimation method considers price endogeneity through simultaneous estimation of demand a...

A generalized weak dominance approach is used to test the documented preference reversal (PR) phenomenon. This approach simply models risky choice behavior in PR as a choice between the best possible outcomes or a choice between the worst possible outcomes by equating smaller paired outcome difference between bets. The preference reversals are therefore seen as a consequence of the fact that ga...

Legal professionals are naturally reluctant to trust fully automated techniques for privilege review. There are certainly cases in which fully manual review is a rational choice, but there are also cases in which reliance on some degree of automation is rational. This paper proposes a model that can help practitioners to make rational choices, and to explain those choices once they have been ma...

In the year 2000, the German government passed the most ambitious tax reform in post-war German history aiming at a significant tax relief for households. One central aim of this tax reform was to improve work incentives and, thereby, foster employment. In this paper, I estimate an intertemporal discrete choice model of female labor supply that allows to analyze the behavioral effects of the ta...

This paper considers the nonparametric identification and estimation of the average effect of a dummy endogenous variable in nonseparable models. The analysis includes the case of a dummy endogenous variable in a discrete choice model as a special case. This paper establishes conditions under which it is possible to identify and consistently estimate the average effect of the dummy endogenous v...

This paper presents an econometric technique for circumventing the lack of individual choice data in a framework of binary choice model by utilizing aggregate choice data. The probability of observing a certain number of individuals making choice A out of the total number of individuals in a group is presented as a sum of probabilities of disjoint events, in which some individuals are picked to...
