This paper proposes a definition of relative uncertainty aversion for decision models under complete uncertainty. It is shown that, for a large class of decision rules characterized by a set of plausible axioms, the new criterion yields a complete ranking…

This paper explores the link between research collaboration and innovation among faculty, as indicated by a self-reported assessment of the contribution of a co-authored publication to knowledge. Findings challenge the assumption that collaborators are rarely involved in theory development and…

The prospect of tuition fee increases for public sector universities has attracted an enormous amount of attention in recent years as governments in all industrialized countries have responded to the converging pressures of increased demands for higher education and rising…

Austria has gone through two cycles of university reforms since the 1960s. The first aimed to open the universities to social and labour market demand and to make their structures more democratic and flexible. The second reform cycle dealt with…

El desarrollo de tecnologías emergentes implica el reto permanente de utilizar nuevas herramientas de gestión tecnológica. La ingeniería de enzimas y su respectiva tecnología, en el contexto de la biotecnología, es una de las áreas del conocimiento sobre las cuales…

This survey presents within a single model three theories of decentralization of decision-making within organizations based on private information and incentives. Renegotiation, collusion, and limits on communication are three sufficient conditions for decentralization to be optimal., Cet article présente, dans…

We analyze an alternative to the standard rationalizability requirement for observed choices by considering non-deteriorating selections. A selection function is a generalization of a choice function where selected alternatives may depend on a reference (or status quo) alternative in addition…

We identify conditions under which preferences over sets of consumption opportunities can be reduced to preferences over bundles of \"commodities\". We distinguish ordinal bundles, whose coordinates are defined up to monotone transformations, from cardinal bundles, whose coordinates are defined up…

This paper provides new versions of Harsanyi’s social aggregation theorem that are formulated in terms of prospects rather than lotteries. Strengthening an earlier result, fixed-population ex-ante utilitarianism is characterized in a multi-profile setting with fixed probabilities. In addition, we extend…

In this article we study the effect of uncertainty on an entrepreneur who must choose the capacity of his business before knowing the demand for his product. The unit profit of operation is known with certainty but there is no…
