This paper addresses the nature, formalization, and neural bases of (affective) social ties and discusses the relevance of ties for health economics. A social tie is defined as an affective weight attached by an individual to the well-being of another individual (‘utility interdependence’)....

When an individual performs several tasks simultaneously, resources must be allocated to different brain systems to produce energy for neurons to fire. Following the evidence from neuroscience, we model the brain as an organization in which a coordinator allocates limited resources to the brain...

We test the hypothesis that "genuine" or "convincing" smiling is a costly signal that has evolved to induce cooperation in situations requiring mutual trust. Potential trustees in a trust game made video clips for viewing by potential trusters before the latter decided whether to send them...

In this Paper, I explore the relationship between native language and use of the Internet and examine whether English is likely to retain its first-mover advantage of a large installed base of English language websites. I study this issue empirically using a unique dataset on (home) Internet use...

We present identification and estimation results for the 'collective' model of labour supply in which there are discrete choices, censoring of hours and non-participation in employment. We derive the collective restrictions on labour supply functions and contrast them with restrictions implied...

This Paper studies the wage effects of the use of alcohol and tobacco. The analysis based on a recent survey in the Netherlands shows that for males the use of tobacco has a negative wage effect of about 10% while the use of alcohol has a positive wage effect of about the same size. Smoking and...

Using a survey approach, we ask consumers to reveal their preferences over pricing schemes that may differ in terms of the average price of consumption, the amount of price variation, and the probability of being rationed. We find that consumers dislike pricing schemes that vary prices more but...

This Paper uses a unique dataset collected among inhabitants of Amsterdam, to study the dynamics in the consumption of cannabis and cocaine. If people start using these drugs they are most likely to do so at age 18-20 for cannabis and age 20-25 for cocaine. An analysis of the starting rates...

In this paper we use individual level data from the Australian National Drug Strategy Household Survey to study the relationship between initiation into cannabis use and educational attainment. Using instrumental variable estimation and bivariate duration analysis we find that those initiating...

This paper investigates whether cannabis use leads to worse mental health. To do so, we account for common unobserved factors affecting mental health and cannabis consumption by modeling mental health jointly with the dynamics of cannabis use. Our main finding is that using cannabis increases...
