We propose a multiplicative speci cation of a discrete choice model that renders choice probabilities independent of the scale of the utility. The scale can thus be random with unspeci ed distribution. The model mostly outperforms the classical additive formulation over a range of stated choice data sets. In some cases, the improvement in likelihood is greater than that obtained from adding obs...

It seems easy to accept that rationality involves many features that cannot be summarized in terms of some straightforward formula, such as binary consistency.  However, this recognition does not immediately lead to alternative characterizations that might be regarded as satisfactory, even though the inadequacies of the traditional assumptions of rational behavior standard used in economic theo...

While winner-take-all crowdsourcing contests are wide spread in practice, several researchers have observed that their social welfare can be poor due to effort exerted by contestants who are never rewarded. In this paper we study the problem of efficiency in winnertake-all crowdsourcing contests. Using a discrete choice model to capture contestants’ production qualities, we introduce a mechanis...

Understanding how users choose tags can help researchers better understand how tagging systems can be used and how to design better tagging systems for the future. We developed a simulation of del.icio.us, a popular social bookmarking tool, that allowed us to simulate users choosing tags using one of four possible strategies for tag choice found in the literature. We then compared the resulting...
