We shed light on assessing product quality in blind tastings and their potential (gender) biases. We study how phonetic traits of grape varieties suggest product attributes in the context of professional reviews. This study aims to close this research gap and analyze how product variety and phonetic name traits affect expert ratings. We obtained data on 18,609 wines and their ratings from Wine Enthusiast Magazine between 1997 and 2016, yielding a sample of 31,058 observations. We suppose that the gender of the taster needs to be considered to understand what affects tastings and ratings, as women and men might be attracted differently to masculine or feminine names. This study shows that masculine names receive higher evaluations than feminine ones. This phonetic gender gap is driven by lower ratings for white wines by female reviewers and lower ratings for red wines by male reviewers. In addition, white wines are rated lower overall by both men and women.

We investigated both the direct and indirect political dividends of public policies by examining Minha Casa, Minha Vida, a housing programme in Brazil that selects its beneficiaries by lottery. We surveyed the lottery participants and found that the winners were not more likely to support the incumbent politicians. Non-beneficiaries, a much larger group, were aware of the programme and thought well of it while the beneficiaries' responses to the programme were sometimes underwhelming. However, politicians considered the programme to be an electoral asset, and a difference-in-differences analysis of electoral results leveraging the roll-out of the programme across municipalities found that presidential and mayoral incumbent candidates performed better in localities that had implemented MCMV. Overall, when the beneficiaries formed a relatively small group, the benefits were conspicuous and the programme's objectives were widely supported. Government programmes can create electoral payoffs independently of how programmes are perceived or experienced by beneficiaries.

Nudging has become a well-known policy practice. Recently, ‘boosting’ has been suggested as an alternative to nudging. In contrast to nudges, boosts aim to empower individuals to exert their own agency to make decisions. This article is one of the first to compare a nudging and a boosting intervention, and it does so in a critical field setting: hand hygiene compliance of hospital nurses. During a 4-week quasi-experiment, we tested the effect of a reframing nudge and a risk literacy boost on hand hygiene compliance in three hospital wards. The results show that nudging and boosting were both effective interventions to improve hand hygiene compliance. A tentative finding is that, while the nudge had a stronger immediate effect, the boost effect remained stable for a week, even after the removal of the intervention. We conclude that, besides nudging, researchers and policymakers may consider boosting when they seek to implement or test behavioral interventions in domains such as healthcare.

Law enforcement agencies are adopting a variety of new surveillance technologies at a fast pace. These technologies could have substantial benefits in terms of public safety, but, for many of them, their ability to reduce crime is unknown. Although a small experimental literature addresses some of these technologies, many of the implementations have been too small to provide an accurate measurement of their potential. In this paper, I explore the advantages and make general suggestions about the use of quasi-experimental methodologies in estimating the public safety benefits of police technology. I also consider the specific case of license plate readers and provide some examples of difference-in-differences approaches that could be used to study their efficacy.

Teachers constitute one of the professional collectives most affected by psychological problems. The purpose of this quasi-experimental study is to examine the efficacy of a mindfulness training programme to reduce psychological distress in a group of teachers. The sample comprised 68 teachers of Secondary School Education, from various public schools; half of them formed the experimental group, and the another half the control group. The levels of psychological distress were measured, in both groups, by the Symptom Checklist-90-R (SCL-90-R) before and after the application of the programme. Statistical analysis shows the significant reduction of three general measures of psychological distress (Global Severity Index, Positive Symptom Distress Index, and Positive Symptom Total), as well in all its dimensions (somatization, obsessive-compulsive, interpersonal sensibility, depression, anxiety, hostility, phobic anxiety, paranoid ideation, and psychoticism), in the experimental group compared with the control group. Follow-up measures show that these results were maintained for four months after termination of the intervention in the experimental group.
