This paper focuses on the construction of a composite indicator for the knowledge based economy using imprecise data. Specifically, for some indicators we only have information on the bounds of the interval within which the true value is believed to lie. The proposed approach is based on a...

We use data from the Survey of Health, Ageing and Retirement in Europe (SHARE) to explain the amount of time invested in volunteering in eight European countries. Direct information on motivations adds to the explanation over and above the effect of socio-demographic variables. The results for...

Ordering infinite utility streams: maximal anonymity

Parental leave policies are often enacted based on the premise that children will bene.t from an extended period of time spent with their parent. A number of research studies have looked at the effect of maternal time investments on the early development of skills, behavioral well-being and...

We provide a revealed preference analysis of the rational addiction model. The revealed preference approach avoids the need to impose an, a priori unverifiable, functional form on the underlying utility function. Our results extend the previously established revealed preference characterizations...

In this paper, we introduce a distinction between interregional and intraregional transportation costs, in a footloose capital model. This allows assessing more precisely the effects of different types of transport policies, on the spatial distribution of activities. From a normative point of...

We consider a setting where a coalition of individuals chooses one or several alternatives from each set in a collection of choice sets. We examine the computational complexity of Pareto rationalizability. Pareto rationalizability requires that we can endow each individual in the coalition with...

The taxation of nuclear energy is studied using a stylized model of the electricity sector, with one dominant nuclear producer and a competitive fringe of fossil-fuel plants. We show that an unanticipated tax on nuclear production can generate significant government revenue in the short run...

In this paper we show that free entry decisions may be socially inefficient, even in a perfectly competitive homogeneous goods market with non-lumpy investments. In our model, inefficient entry decisions are the result of risk-aversion of incumbent producers and consumers, combined with...

All individuals belong to a social network with certain quality level. This paper analyzes the role of the quality of the social network in the educational decision making process. We propose a measure for quality of network based on the schooling level and the labor position of the members of...
