Publication The Formality Effect(Harvard Kennedy School, 2023-01) Linos, Elizabeth; Lasky-Fink, Jessica; Larkin, Chris; Moore, Lindsay; Kirkman, ElspethThis paper documents the existence of a “Formality Effect” in government communications. Across three online studies and three field experiments in different policy contexts (total N = 67,632), we show that, contrary to scholar and practitioner predictions, formal government communications are more effective at influencing resident behavior than informal government communications. In exploring mechanisms, we show that formality operates as a heuristic for credibility and importance. Recipients view the source of a formal letter as more competent and trustworthy, and view the request itself as more important to take action on, despite no change in comprehension nor in perceived ease of taking action. These findings have immediate implications for government communicators and open the door for a renewed focus on how the design and presentation of information impacts behavior.Publication Curbing adult student attrition: Evidence from a field experiment(2015-04-06) Chande, Raj; Luca, Michael; Sanders, Michael; Soon, Xian‐Zhi; Borcan, Oana; Linos, Elizabeth; Kirkman, Elspeth; Robinson, SeanRoughly 20% of adults in the OECD lack basic numeracy and literacy skills. In the UK, many colleges offer fully government subsidized adult education programs to improve these skills. Constructing a unique dataset consisting of weekly attendance records for 1179 students, we find that approximately 25% of learners stop attending these programs in the first ten weeks and that average attendance rates deteriorate by 20% in that time. We implement a large‐scale field experiment in which we send encouraging text messages to students. Our initial results show that these simple text messages reduce the proportion of students that stop attending by 36% and lead to a 7% increase in average attendance relative to the control group. The effects on attendance rates persist through the three weeks of available data following the initial intervention.Publication Indoor Tanning and Non-Melanoma Skin Cancer: Systematic Review and Meta-Analysis(BMJ Publishing Group Ltd., 2012) Wehner, Mackenzie R; Shive, Melissa Lily; Chren, Mary-Margaret; Han, Jiali; Qureshi, Abrar A; Linos, ElizabethObjective: To synthesise the literature on indoor tanning and non-melanoma skin cancer. Design: Systematic review and meta-analysis. Data sources: PubMed (1966 to present), Embase (1974 to present), and Web of Science (1898 to present). Study selection: All articles that reported an original effect statistic for indoor tanning and non-melanoma skin cancer were included. Articles that presented no data, such as review articles and editorials, were excluded, as were articles in languages other than English. Data extraction: Two investigators independently extracted data. Random effects meta-analysis was used to summarise the relative risk of ever use versus never use of indoor tanning. Dose-response effects and exposure to indoor tanning during early life were also examined. The population attributable risk fraction for the United States population was calculated. Results: 12 studies with 9328 cases of non-melanoma skin cancer were included. Among people who reported ever using indoor tanning compared with those who never used indoor tanning, the summary relative risk for squamous cell carcinoma was 1.67 (95% confidence interval 1.29 to 2.17) and that for basal cell carcinoma was 1.29 (1.08 to 1.53). No significant heterogeneity existed between studies. The population attributable risk fraction for the United States was estimated to be 8.2% for squamous cell carcinoma and 3.7% for basal cell carcinoma. This corresponds to more than 170 000 cases of non-melanoma skin cancer each year attributable to indoor tanning. On the basis of data from three studies, use of indoor tanning before age 25 was more strongly associated with both squamous cell carcinoma (relative risk 2.02, 0.70 to 5.86) and basal cell carcinoma (1.40, 1.29 to 1.52). Conclusions: Indoor tanning is associated with a significantly increased risk of both basal and squamous cell skin cancer. The risk is higher with use in early life (<25 years). This modifiable risk factor may account for hundreds of thousands of cases of non-melanoma skin cancer each year in the United States alone and many more worldwide. These findings contribute to the growing body of evidence on the harms of indoor tanning and support public health campaigns and regulation to reduce exposure to this carcinogen.Publication Improving delivery of the social safety net: The role of stigma(Harvard Kennedy School, 2023-01) Lasky-Fink, Jessica; Linos, ElizabethMany low-income households in the US miss out on social safety net benefits because of the information, compliance, and psychological costs associated with take-up of government assistance. Yet, the empirical evidence on the impact of learning and psychological costs on take-up, and how to reduce them, is mixed. Leaning on an administrative burden framework, this paper measures the role of reducing learning costs and stigma on demand for rental assistance in two field experiments (N = 117,073) conducted in two US cities. We find that providing information about emergency rental assistance increased program application requests by 52% compared to a no-communication control group. Moreover, subtle framing changes aimed at destigmatizing rental assistance increased engagement with the communication by 36% and increased application requests by about 18% relative to an information-only group, with potentially larger effects for renters of color. In two subsequent online experiments (N = 1,258), we document that the destigmatizing framing reduces internalized stigma, without affecting perceptions of the program itself.Publication Intersectional Peer Effects at Work: The Effect of White Coworkers on Black Women's Careers(Harvard Kennedy School, 2023-11) Linos, Elizabeth; Mobasseri, Sanaz; Roussille, NinaThis paper investigates how having more White coworkers influences the subsequent retention and promotion of Black women. Studying 9,037 new hires at a professional services firm, we first document large racial turnover and promotion gaps: even after controlling for observable characteristics, Black employees are 6.7 percentage points (32%) more likely to turn over within two years and 18.7 percentage points (26%) less likely to be promoted on time than their White counterparts. The largest turnover gap is between Black and White women, at 8.9 percentage points (51%). We argue that initial assignment to project teams is conditionally random, based on placebo tests and qualitative evidence. Under the assumption of conditional random assignment, we show that a one standard deviation (20.8 percentage points) increase in the share of White coworkers is associated with a 15.8 percentage point increase in turnover and an 11.5 percentage point decrease in promotion for Black women. We refer to these effects as intersectional: Black women are the only race-gender group whose turnover and promotion is negatively impacted by White coworkers. We explore potential causal pathways through which these peer effects may emerge: Black women who were initially assigned to Whiter teams are subsequently more likely to be labeled as low performers and report fewer billable hours, both of which are predictors of higher turnover and lower promotion for all employees. Our findings contribute to the literatures on peer effects, intersectionality, and the practice of managing race and gender inequality in organizations.
