Sports provide a natural experiment on individual choices in games with high stakes. We study soccer, analysing a simple game theoretic model of a match and using data to evaluate the performance of this model in explaining actual behaviour. A team's optimal strategy depends on the current state of the game. When the game is tied, both teams attack because this maximises their probability of sc...

Recent experiments suggest that people’s preferences not only depend on their choices but also on their beliefs of other people’s choices and on their beliefs of other people’s beliefs. Guilt aversion is such belief-dependent preference that has received a lot of attention recently. An individual is considered to be guilt averse if he gets a negative utility from failing to live up to the belie...

In this paper some boosting and on-line allocation strategies are revisited in order to provide new proofs inspired by Chernoo's bounding techniques taken from common Probability Theory. Even if some of the results presented here are weaker than the best known today, the generalized style of the proofs hopefully ooers a better understanding of known results and suggests new strategies. This pap...

Do people integrate all the information at hand when they make choices or do they employ heuristics that ignore some of it? Recent research indicates that people’s behavior should and does depend on the statistical properties of the environments within which cognition operates. However, in a single environment there are always decision makers who rely on less effective strategies. The source of...

Discrete choice models as demand forecasting techniques have been used for transportation applications for more than thirty years. The multinomial and nested logit models are probably the most widely applied in this context. Alternative speciic constants (ASCs), although playing an important role in these models, have received very little attention in theoretical studies. In this paper, we try ...

“Scientific and technical human capital” (S&T human capital) has been defined as the sum of researchers’ professional network ties and their technical skills and resources [Int. J. Technol. Manage. 22 (7–8) (2001) 636]. Our study focuses on one particular means by which scientists acquire and deploy S&T human capital, research collaboration. We examine data from 451 scientists and engineers at ...
