Kristina Burström, Magnus Johannesson, Finn Diderichsen
The study aimed to estimate the value of the change in health in Sweden 1980|81 to 1996|97. Quality-adjusted life years (QALYs) for men and women at specific ages were estimated for 1980|81, 1988|89...
Ellingsen, Tore, Johannesson, Magnus
Casual observation suggests that people are more generous with their time than with their money. In this paper we present experimental evidence supporting the hypothesis. A third of our subjects...
Ellingsen, Tore, Johannesson, Magnus
We develop a simple model of generous behavior. It is based on the premise that some people are generous, but everyone wants to appear generous. Although non-monetary donations are always...
Ellingsen, Tore, Johannesson, Magnus, Lilja, Jannie, Zetterqvist, Henrik
In a laboratory experiment, we create relationships between pairs of anonymous subjects through a Prisoners' dilemma game. Thereafter the same subjects play a private values (sealed-bid double...

Anticipated verbal feedback induces altruistic behavior
Ellingsen, Tore, Johannesson, Magnus
A distinctive feature of humans compared to other species is the high rate of cooperation with non-kin. One explanation is that humans are motivated by concerns for social esteem. In this paper we...
Fredric Jacobsson, Magnus Johannesson, Lars Borgquist
We test if altruism is paternalistic with respect to health. Subjects can donate money or nicotine patches to a smoking diabetes patient whose willingness to pay for nicotine patches is positive but...
Heritability of ultimatum game responder behavior
Wallace, Björn, Cesarini, David, Lichtenstein, Paul, Johannesson, Magnus

Alan J. Zillich, Karen Blumenschein, Magnus Johannesson, Patricia Freeman
Objective:The primary objective was to evaluate the relationship between willingness-to-pay (WTP), quality-of-life (QOL), and disease-severity measures in patients with asthma. The hypothesis studied...
Promises, Threats and Fairness
Tore Ellingsen, Magnus Johannesson
We present experimental evidence that promises and threats mitigate the hold-up problem. While investors rely as much on their own threats as on their trading partner's promises, the latter are more...
Do Life-Saving Regulations Save Lives?
Gerdtham, Ulf-G, Johannesson, Magnus
Life-saving regulations may be counter-productive since they have an indirect mortality effect through the reduction in disposable income. This paper estimates the effect of income on mortality,...
On the Value of Changes in Life Expectancy: Blips versus Parametric Changes.
Johannesson, Magnus, Johansson, Per-Olov, Lofgren, Karl-Gustaf
We estimate the value of a 'blip', i.e. an immediate small reduction, in the hazard rate for a random sample of Swedes. Since the risk reduction is age-independent (2 'extra saved lives' out of...
Saving Lives in the Present versus Saving Lives in the Future--Is There a Framing Effect?
Johannesson, Magnus, Johansson, Per-Olov
To estimate the discount rate for lives saved in the future a number of studies have been carried out on the trade-off between saving lives now and in the future. A telephone survey is administered...
Characterizing QALYs by Risk Neutrality.
Bleichrodt, Han, Wakker, Peter, Johannesson, Magnus
This paper shows that QALYs can be derived from more elementary conditions than thought hitherto in the literature: it suffices to impose risk neutrality for life years in every health state. This...
Johannesson, Magnus, Johansson, Per-Olov

Billiards and Brains: Cognitive Ability and Behavior in a p-Beauty Contest
Burnham, Terence C., Cesarini, David, Wallace, Björn, Johannesson, Magnus, Lichtenstein, Paul
"Beauty contests" are well-studied, dominance-solvable games that generate two interesting results. First, most behavior does not conform to the unique Nash equilibrium. Second, there is considerable...
Tore Ellingsen, Magnus Johannesson
Why do people work? Economic theory generally, and the principal–agent model specifically, emphasize the role of material incentives. But many academics, for example, work diligently year after...
Ellingsen, Tore, Johannesson, Magnus, Tjøtta, Sigve, Torsvik, Gaute
Guilt averse individuals experience a utility loss if they believe they let someone down. In particular, generosity depends on what the donor believes that the recipient expects to receive. In...
Eliciting Willingness to Pay Without Bias: Evidence from a Field Experiment
Karen Blumenschein, GlennC. Blomquist, Magnus Johannesson, Nancy Horn, Patricia Freeman
Concern exists that hypothetical willingness to pay questions overestimate real willingness to pay. In a field experiment, we compare two methods of removing hypothetical bias, a cheap talk approach...

A Note on Confidence Intervals in Cost-Effectiveness Analysis
Tambour, Magnus, Zethraeus, Niklas, Johannesson, Magnus
How to obtain confidence intervals for cost-effectiveness ratios is complicated by the statistical problems to obtain a confidence interval for a ratio of random variables. Different approaches have...
Time Spent on Waiting Lists for Medical Care: An Insurance Approach
Johannesson, Magnus, Johansson, Per-Olov, Söderqvist, Tore
In this paper, we develop a simple model of the benefits and costs of being on a waiting list. The model shows that complex factors are in operation, implying that a shorter waiting time need not...
