“This paper examines empirically the hypothesis made famous by Nobel Laureates Friedrich A. Hayek and Milton Friedman that societies with high levels of political freedom must also have high levels of economic freedom. In our judgment, the Hayek-Friedman hypothesis holds up fairly well to historical scrutiny. Using data on economic and political freedom for a sample of up to 123 nations back as far as 1970, we find relatively few instances of societies combining relatively high political freedom without relatively high levels of economic freedom. In addition, we find that these cases are diminishing over time. Finally, we examine several cases of countries on different economic and political freedom journeys.”

“This paper studies the relationship between height and leadership. Using data from a representative sample of Swedish men, I document that tall men are significantly more likely to attain managerial positions. An increase in height by 10 centimeters (3.94 inches) is associated with a 2.2 percentage point increase in the probability of holding a managerial position. Selection into managerial positions explains about 15 percent of the unconditional height wage premium. However, at least half of the height-leadership correlation is due to a positive correlation between height and cognitive and noncognitive ability.”

“Research suggests that living in and adapting to foreign cultures facilitates creativity. The current research investigated whether one aspect of the adaptation process—multicultural learning—is a critical component of increased creativity. Experiments 1-3 found that recalling a multicultural learning experience: (a) facilitates idea flexibility (e.g., the ability to solve problems in multiple ways), (b) increases awareness of underlying connections and associations, and (c) helps overcome functional fixedness. Importantly, Experiments 2 and 3 specifically demonstrated that functional learning in a multicultural context (i.e., learning about the underlying meaning or function of behaviors in that context) is particularly important for facilitating creativity. Results showed that creativity was enhanced only when participants recalled a functional multicultural learning experience and only when participants had previously lived abroad. Overall, multicultural learning appears to be an important mechanism by which foreign living experiences lead to creative enhancement.”

“Performance (such as a course grade) is a joint function of an individual’s ability (such as intelligence) and the situation (such as the instructor’s grading leniency). Prior research has documented a human bias toward dispositional inference, which ascribes performance to individual ability, even when it is better explained through situational influences on performance. It is hypothesized here that this tendency leads admissions decisions to favor students coming from institutions with lenient grading because those students have their high grades mistaken for evidence of high ability. Three experiments show that those who obtain high scores simply because of lenient grading are favored in selection. These results have implications for research on attribution because they provide a more stringent test of the correspondence bias and allow for a more precise measure of its size. Implications for university admissions and personnel selection decisions are also discussed.”

“Each July thousands begin medical residencies and acquire increased responsibility for patient care. Many have suggested that these new medical residents may produce errors and worsen patient outcomes—the so-called “July Effect;” however, we have found no U.S. evidence documenting this effect. … We examined all U.S. death certificates, 1979–2006 (n = 62,338,584), focusing on medication errors (n = 244,388). We compared the observed number of deaths in July with the number expected, determined by least-squares regression techniques. We compared the July Effect inside versus outside medical institutions. We also compared the July Effect in counties with versus without teaching hospitals. … Inside medical institutions, in counties containing teaching hospitals, fatal medication errors spiked by 10% in July and in no other month [JR = 1.10 (1.06–1.14)]. In contrast, there was no July spike in counties without teaching hospitals. The greater the concentration of teaching hospitals in a region, the greater the July spike (r = .80; P = .005). These findings held only for medication errors, not for other causes of death. … We found a significant July spike in fatal medication errors inside medical institutions. After assessing competing explanations, we concluded that the July mortality spike results at least partly from changes associated with the arrival of new medical residents.”

“Imagine you are standing at a street with heavy traffic watching someone on the other side of the road. Do you think your brain is implicitly registering your willingness to buy any of the cars passing by outside your focus of attention? To address this question, we measured brain responses to consumer products (cars) in two experimental groups using functional magnetic resonance imaging. Participants in the first group (high attention) were instructed to closely attend to the products and to rate their attractiveness. Participants in the second group (low attention) were distracted from products and their attention was directed elsewhere. After scanning, participants were asked to state their willingness to buy each product. During the acquisition of neural data, participants were not aware that consumer choices regarding these cars would subsequently be required. Multivariate decoding was then applied to assess the choice-related predictive information encoded in the brain during product exposure in both conditions. Distributed activation patterns in the insula and the medial prefrontal cortex were found to reliably encode subsequent choices in both the high and the low attention group. Importantly, consumer choices could be predicted equally well in the low attention as in the high attention group. This suggests that neural evaluation of products and associated choice-related processing does not necessarily depend on attentional processing of available items. Overall, the present findings emphasize the potential of implicit, automatic processes in guiding even important and complex decisions.”

“Trust plays an important role in the formation and maintenance of human social relationships. But trusting others is associated with a cost, given the prevalence of cheaters and deceivers in human society. Recent research has shown that the peptide hormone oxytocin increases trust in humans. However, oxytocin also makes individuals susceptible to betrayal, because under influence of oxytocin, subjects perseverate in giving trust to others they know are untrustworthy. Testosterone, a steroid hormone associated with competition and dominance, is often viewed as an inhibitor of sociality, and may have antagonistic properties with oxytocin. The following experiment tests this possibility in a placebo-controlled, within-subjects design involving the administration of testosterone to 24 female subjects. We show that compared with the placebo, testosterone significantly decreases interpersonal trust, and, as further analyses established, this effect is determined by those who give trust easily. We suggest that testosterone adaptively increases social vigilance in these trusting individuals to better prepare them for competition over status and valued resources. In conclusion, our data provide unique insights into the hormonal regulation of human sociality by showing that testosterone downregulates interpersonal trust in an adaptive manner.”

“In this paper we empirically test if loss-aversion affects household participation in equity markets, household allocations to equity, and household allocations between mutual funds and individual stocks. Using household survey data, we obtain direct measures of each surveyed household’s loss-aversion coefficient from questions involving hypothetical payoffs. We find that higher loss-aversion is associated with a lower probability of participation. We also find that higher loss-aversion reduces the probability of direct stockholding by significantly more than the probability of owning mutual funds. After controlling for sample selection we do not find a relationship between loss-aversion and portfolio allocations to equity.”

“Research shows that many animal species have morphological and cognitive adaptations for fighting with others to gain resources, but it remains unclear how humans make fighting decisions. Non-human animals often adaptively calibrate fighting behavior to ecological variables such as resource quantity and whether the resource is distributed uniformly or clustered in patches. Also, many species use strategies to reduce fighting costs such as resolving disputes based on power asymmetries or conventions. Here we show that humans apply an ownership convention in response to the problem of severe fighting. We designed a virtual environment where ten participants, acting as avatars, could forage and fight for electronic food items (convertible to cash). In the patchy condition, we observed an ownership convention—the avatar who arrives first is more likely to win—but in the uniform condition, where severe fighting is rare, the ownership convention is absent.”

“This paper examines the impact of parental investments on the development of cognitive, mental and emotional skills during childhood using data from a longitudinal study, the Mannheim Study of Children at Risk, starting at birth. Our work offers three important innovations. First, we use reliable measures of the child’s cognitive, mental and emotional skills as well as accurate measures of parental investment. Second, we estimate latent factor models to account for unobserved characteristics of children. Third, we examine the skill development for girls and boys separately, as well as for children who were born with either organic or psychosocial risk. We find a decreasing impact of parental investments on cognitive and mental skills, while emotional skills seem to be unaffected by parental investment throughout childhood. Thus, initial inequality persists during childhood. Since families are the main sources of education during the first years of life, our results have important implications for the quality of the parent-child relationship.”

“Studies regularly link levels of educational attainment to civic behavior and attitudes, but only a few investigate the role played by specific coursework. Using data collected from students who attended one of four public universities in our study, we investigate the relationship between economics coursework and civic behavior after graduation. Drawing from large samples of students in economics, business, or general majors, we compare responses across the three groups and by the number of undergraduate economics courses completed. We find that undergraduate coursework in economics is strongly associated with political party affiliation and with donations to candidates or parties, but not with the decision to vote or not vote. Nor is studying economics correlated with the likelihood (or intensity of) volunteerism. While we find that the civic behavior of economics majors and business majors is similar, it appears that business majors are less likely than general majors to engage in time-consuming behaviors such as voting and volunteering. Finally, we extend earlier studies that address the link between economics coursework and attitudes on public policy issues, finding that graduates who studied more economics usually reported attitudes closer to those expressed in national surveys of U.S. economists. Interestingly, we find the public policy attitudes of business majors to be more like those of general majors than of economics majors.”
