Although people often assume that multiple motives for doing something will be more powerful and effective than a single motive, research suggests that different types of motives for the same action sometimes compete. More specifically, research suggests that instrumental motives, which are extrinsic to the activities at hand, can weaken internal motives, which are intrinsic to the activities a...

This article reports the results of a simple bargaining experiment on the ultimatumrevenge game. The game enables to differentiate between fairness that is stimulated by intentional based motives, distributional motives, and fairness considerations that mix both motives. The laboratory experiments indicate considerable heterogeneity of motives. A majority of subjects seem to combine both motive...

Few retirees annuitize any wealth, a fact that has so far defied explanation within the standard framework of forward-looking, expected utility-maximizing agents. Bequest motives seem a natural explanation. Yet the prevailing view is that people with plausible bequest motives should annuitize part of their wealth, and thus that bequest motives cannot explain why most people do not annuitize any...

A motivational model of alcohol involvement (M. L. Cooper, M. R. Frone, M. Russell, & P. Mudar, 1995) was replicated and extended by incorporating social antecedents and motives and by testing this model cross-sectionally and longitudinally in a sample of college students. Participants (N = 388) completed a questionnaire battery assessing alcohol use and problems, alcohol expectancies, sensatio...

Let k be a perfect field. In this paper we prove that biextensions of 1-motives define multilinear morphisms between 1-motives in Voevodsky’s triangulated category DM gm(k, Q) of effective geometrical motives over k with rational coefficients.

In this article we introduce the category of noncommutative Artin motives as well as the category of noncommutative mixed Artin motives. In the pure world, we start by proving that the classical category AM(k)Q of Artin motives (over a base field k) can be characterized as the largest category inside Chow motives which fully-embeds into noncommutative Chow motives. Making use of a refined bridg...
