We derive necessary and sufficient conditions in order for binary voting choices over a finite number of pairs of alternatives to be consistent with voter preferences that admit concave utility representations. These conditions imply simple testable restrictions on the location of voters’ ideal points, and can be used to predict individual voting behavior. On the other hand, if the location of ...

People’s choices can be predicted given information about their preferences. Learning people’s preferences is the inverse problem of inferring preferences from choices. Given the apparent relationship between choice prediction and preference learning, it is natural to ask whether the two are mutually consistent. Given weak assumptions, we show that no single, consistent model of the relationshi...

This paper studies differences in inequality perceptions, distributional norms, and redistributive preferences between East and West Germany. As expected, there are substantial differences with respect to all three of these measures. Surprisingly, however, differences in distributional norms are much smaller than differences with respect to inequality perceptions or redistributive preferences. ...

In allocating goods with no use of monetary transfers, random allocation mechanisms can be designed in order to elicit information on preference intensities. I study the nontransfer allocation of two ex-ante identical objects under Bayesian incentive compatibility, with symmetric agents and independent private valuations. I …nd the ex-ante utilitarian-optimal mechanism, in which the probability...

consumers have different needs and desires in their relationship with service firms and not every consumer is willing to engage in close commercial relationship in the same manner. although customer relationship management (crm) is a top priority for marketers, scholars and managers do not appropriately understand these distinct relational preferences. this article introduces ‘customer attachme...

Efficient multi-receiver delivery of video data over computer networks, such as the Internet is still challenging, due to heterogeneity in involved network technologies, end-node capabilities and receiver preferences. While adaptive and scalable video encoding can solve many of the problems caused by heterogeneity, media gateway systems are needed for performing video filtering and transformati...
