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...

China is undergoing changes in its demographic structure, and the burden of raising children caring for elderly negatively affecting welfare Chinese families. Optimising financial structure households may be an effective solution. Using data from 2017 Household Finance Survey, this study, we empirically analyse how age population affects a household’s finances by applying probit tobit models. I...

Knowing the users is capital for building user-friendly digital interfaces. One way to think about the users is considering their familiarity with this technology. This article presents the results of twelve interviews with elderly people residing in the so-called South Zone of Rio de Janeiro (Brazil) who have used mobile phones over at least one year. It is part of the Doctor's Thesis "Mobile ...

Home and community-based care programs have been growing due to the preferences of elderly clients to remain in their homes. This study examines factors associated with the transfer of the elderly from a home or community-based long-term care program to a nursing home. Data were collected from four suburban counties administered by an agency in the Ohio pre-admission screening system providing ...

McKinsey–Tarski (1944), Shehtman (1999), and Lucero-Bryan (2011) proved completeness theorems for modal logics with modalities 2, 2 and ∀, and [∂] and ∀, respectively, with topological semantics over the real numbers. We give short proofs of these results using lexicographic sums of linear orders.

The paper investigates the public’s attitude towards monetary union arrangements associated with different levels of monetary policy autonomy. The results indicate that support for monetary union declines significantly with expected loss of autonomy. Survey data from Kenya shows that public support for the proposed East African Community monetary union is highest in an arrangement where the cou...
