Do More Expensive Wines Taste Better? Evidence from a Large Sample of Blind Tastings

- Individuals who are unaware of the price do not derive more enjoyment from more expensive wine. In a sample of more than 6,000 blind tastings, we find that the correlation between price and overall rating is small and negative, suggesting that individuals on average enjoy more expensive wines slightly less. For individuals with wine training, however, we find indications of a non-negative relationship between price and enjoyment. Our results are robust to the inclusion of individual fixed effects, and are not driven by outliers: when omitting the top and bottom deciles of the price distribution, our qualitative results are strengthened, and the statistical significance is improved further. These findings suggest that non-expert wine consumers should not anticipate greater enjoyment of the intrinsic qualities of a wine simply because it is expensive or is appreciated by experts.

- Images of half-dressed women are ubiquitous in advertising and popular culture. Yet little is known about the potential impacts of such images on economic decision making. We randomize 648 participants of both genders to advertising images including either women in bikini or underwear, fully dressed women, or no women, and examine the effects on risk taking, willingness to compete and math performance in a lab experiment. We find no treatment effects on any outcome measure for women. For men, our results indicate that men take more risk after having been exposed to images of half-dressed women compared to no women.

Variability in the analysis of a single neuroimaging dataset by many teams

Tidskriftsartikel (refereegranskat)abstract
- Data analysis workflows in many scientific domains have become increasingly complex and flexible. Here we assess the effect of this flexibility on the results of functional magnetic resonance imaging by asking 70 independent teams to analyse the same dataset, testing the same 9 ex-ante hypotheses(1). The flexibility of analytical approaches is exemplified by the fact that no two teams chose identical workflows to analyse the data. This flexibility resulted in sizeable variation in the results of hypothesis tests, even for teams whose statistical maps were highly correlated at intermediate stages of the analysis pipeline. Variation in reported results was related to several aspects of analysis methodology. Notably, a meta-analytical approach that aggregated information across teams yielded a significant consensus in activated regions. Furthermore, prediction markets of researchers in the field revealed an overestimation of the likelihood of significant findings, even by researchers with direct knowledge of the dataset(2-5). Our findings show that analytical flexibility can have substantial effects on scientific conclusions, and identify factors that may be related to variability in the analysis of functional magnetic resonance imaging. The results emphasize the importance of validating and sharing complex analysis workflows, and demonstrate the need for performing and reporting multiple analyses of the same data. Potential approaches that could be used to mitigate issues related to analytical variability are discussed. The results obtained by seventy different teams analysing the same functional magnetic resonance imaging dataset show substantial variation, highlighting the influence of analytical choices and the importance of sharing workflows publicly and performing multiple analyses.

Evaluating replicability of laboratory experiments in economics

Ingår i: Science. - : American Association for the Advancement of Science (AAAS). - 0036-8075 .- 1095-9203. ; 351:6280, s. 1433-1436

Tidskriftsartikel (refereegranskat)abstract
- The replicability of some scientific findings has recently been called into question. To contribute data about replicability in economics, we replicated 18 studies published in the American Economic Review and the Quarterly Journal of Economics between 2011 and 2014. All of these replications followed predefined analysis plans that weremade publicly available beforehand, and they all have a statistical power of at least 90% to detect the original effect size at the 5% significance level. We found a significant effect in the same direction as in the original study for 11 replications (61%); on average, the replicated effect size is 66% of the original. The replicability rate varies between 67% and 78% for four additional replicability indicators, including a prediction market measure of peer beliefs.

Gender, Financial Literacy and Stock Market Participation
- 2011
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Women typically participate less than men in the stock market, while also scoring lower on financial literacy. We explore the link between the gender gap in stock market participation and financial literacy. Using survey data on a random sample of 1,300 individuals that is representative of the Swedish population, we show that controlling for basic financial literacy, essentially a measure of numeracy that does not require knowledge about the stock market, may explain a large part of the gender gap in stock market participation. We also find that women report being less risk taking than men. This gender gap in risk attitudes remains significant also when controlling for financial literacy.
