Fatal attraction: ventral striatum predicts costly choice errors in humans
Animals approach rewards and cues associated with reward, even when this behavior is irrelevant or detrimental to the attainment of these rewards. Motivated by these findings we study the biology of financially-costly approach behavior in humans. Our subjects passively learned to predict the occurrence of erotic rewards. We show that neuronal responses in ventral striatum during this...

A dynamic hurdle model for zero-inflated count data: with an application to health care utilization
Excess zeros are encountered in many empirical count data applications. We provide a new explanation of extra zeros, related to the underlying stochastic process that generates events. The process has two rates, a lower rate until the first event, and a higher one thereafter. We derive the corresponding distribution of the number of events during a fixed period and extend it to...

We distinguish between unilateral and bilateral connections and between targeted and collective information sharing. Agents value being connected to other agents and sharing and receiving information. We...

Protestantism and education: Reading the Bible and other skills.
During industrialization, Protestants were more literate than Catholics. This paper investigates whether this fact may be led back to the intrinsic motivation of Protestants to read the bible and to what extent other education motives might have been involved as well. We employ a historical data set from Switzerland which allows us to differentiate between different cognitive skills...

The motivation and impact of organized public resistance against agricultural biotechnology
Fifteen years of experience with the commercial cultivation of genetically modified (GM) corps and countless national and international risk assessments of genetically modified organisms (GMOs) suggest that the risks related to this new technology are not any different from those already known in conventional agriculture. Despite these reassuring findings, public distrust toward GMOs...
