We propose a consistent utility-based framework to jointly explain a household's decisions on purchase incidence, brand choice and purchase quantity. The approach differs from other approaches, currently available in the literature, as it is able to take into account consumption dynamics. In the...

This discussion paper resulted in a publication in the <I>Journal of Economic Behavior & Organization</I> (2008), volume 66, pages 243-250.<P> We study fairness and reciprocity in a Hawk-Dove game. This alllows us to testvarious models in one framework. We observe a large extent of selfish and...</p></i>

The effects of stake size on cooperation and punishment are investigated using a public goods experiment. We find that an increase in stake size does neither significantly affect cooperation nor, interestingly, the level of punishment.

Explaining the evolution and maintenance of cooperation among unrelated individuals is one of the fundamental problems in biology and the social sciences. Recent experimental evidence suggests that altruistic punishment is an important mechanism to maintain cooperation among humans. In this...

While most papers_new on team decision-making find teams to behave more selfish, less trusting and less altruistic than individuals, Cason and Mui (1997) report that teams are more altruistic than individuals in a dictator game. Using a within-subjects design we re-examine group polarization by...

The papers in this special issue of Mathematics and Computers in Simulation are substantially revised versions of the papers that were presented at the 2011 Madrid International Conference on “Risk Modelling and Management” (RMM2011). The papers cover the following topics: currency hedging...

Accepted for the <I>Journal of the Royal Statistical Society Series A</A> (2014).<P> Attack and defense strengths of football teams vary over time due to changes in the teams of players or their managers. We develop a statistical model for the analysis and forecasting of football match results which are...</p></i>

Since the early nineties, the Dutch tax system allows for a tax-favored form of risk free savings through employer-sponsored savings plans (ESSPs). Under some conditions and up to a certain amount, the contributions to this planare tax-deductible, and the returns as well as the withdrawals are...

We study the forecasting of the yearly outcome of the Boat Race between Cambridge and Oxford. We compare the relative performance of different dynamic models for forty years of forecasting. Each model is defined by a binary density conditional on a latent signal that is specified as a dynamic...

Using Italian data, we estimate an option value model to quantify the effectof financial incentives on retirement choices. As far as we know, this isthe first empirical study to estimate the conditional multiple-years modelput forward by Stock and Wise (1990). This implies that we account...
