In this paper, we use a sample of almost 30,000 Swedish mono- and dizygotic twins to study the heritability of financial risk-taking. Following a major pension reform in the year 2000, virtually all Swedish adults had to simultaneously make a financial decision affecting post-retirement wealth....

Twins-based estimates of the return to schooling feature prominently in the labor economics literature. The validity of such estimates hinges critically on the assumption that within-pair variation in schooling is explained by factors which are unrelated to wage earning ability. This paper...

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 experimental work, several authors have identified a positive correlation between such second-order...

We study the choice of drug for the treatment of high blood pressure (hypertension) in Sweden between 1988-1994. During this time period calcium antagonists and ACE-inhibitors increased their market shares at the expense of the older drugs diuretics and beta-blockers. We use a prescription micro...

We experimentally investigate the effect of cheap talk in a bargaining game with one-sided asymmetric information. A seller has private information about his or her skill and is provided an opportunity to communicate this information to a buyer through a written message. Four different...

We rigorously test for ethnic discrimination in high school grading in Sweden. A random sample of the national tests in the Swedish language is graded both non-blind by the student's own teacher and blind without any identifying information. The increase in the test score due to non-blind...

Reciprocal behavior, the rewarding of kind acts and the punishment of unkind acts, is relatively well established among adults. We test if reciprocal behavior exists already among children 3-8 years old. Three simple anonymous allocation games are conducted with 242 children. In a first stage,...

In this paper, we use the classical twin design to provide estimates of genetic and environmental influences on experimentally elicited preferences for risk and giving. Using standard methods from behavior genetics, we find strong prima facie evidence that these preferences are broadly heritable...
