Reducing Discrimination through Norms or Information: Evidence from a Field Experiment on Student Evaluations of Teaching

We conduct a field experiment to assess the impact of two different interventions designed to reduce gender biases in student evaluations of teaching (SET). In the first intervention, students received a normative statement by email, essentially reminding them that they should not discriminate in SETs. In the second intervention, the normative statement was augmented with precise information on how other students in the exact same situation had discriminated against female teachers in the past. While the pure normative statement had no significant impact on SETs, the informative statement appears to have reduced gender biases against female teachers. This effect mainly comes from a change in male students’ evaluation of female teachers

Reducing Discrimination in the Field:Evidence from an Awareness Raising Intervention Targeting Gender Biases in Student Evaluations of Teaching

This paper presents the results of a field experiment designed to reduce gender discrimination in student evaluations of teaching (SET). In the first intervention, students receive a normative statement reminding them that they should not discriminate in SETs. In the second intervention, the normative statement includes precise information about how other students (especially male students) have discriminated against female teachers in previous years. The purely normative statement has no significant impact on SET overall satisfaction scores, suggesting that a blanket awareness-raising campaign may be inefficient to reduce discrimination. However, the informational statement appears to significantly reduce gender discrimination. The effect we find mainly comes from a change in male students’ evaluation of female teachers

Turning back the clock: Beliefs about gender roles during lockdown

We study the impact of lockdown measures on beliefs about gender roles. We collect data from a representative sample of 1000 individuals in France during the first COVID-19 lockdown in 2020. To measure beliefs about gender roles, we use questions from the 2018 wave of the European Values Study, and match respondents from the two surveys to compare beliefs before and during lockdown. We find evidence that the lockdown period was associated with a shift towards more traditional beliefs about gender roles. The effects are concentrated among men from the most time-constrained households and from households where bargaining with a partner over sharing responsibility for household production was likely to be an issue. Finally, we find correlational evidence that beliefs in equal gender roles increase with household income. Overall, our results suggest that men are more likely to hold egalitarian beliefs about gender roles when these beliefs are not costly for them

Aspiring Top Civil Servants' Distrust in the Private Sector

In this paper, we assess the beliefs of aspiring top civil servants towards the private sector. We use a survey conducted in a French university known for training most of the future high-ranking civil servants and politicians, as well as students who will work in the private sector. Our results show that students aspiring to work in the public sector are more likely to distrust the private sector, to believe that conducting business is easy, and are less likely to see the benefits of public-private partnerships. They are also more likely to believe that private sector workers are self-interested. These results have strong implications for the level of regulation in France, and the cooperation between the public and private sector

Student evaluations of teaching are not only unreliable, they are significantly biased against female instructors

A series of studies across countries and disciplines in higher education confirm that student evaluations of teaching (SET) are significantly correlated with instructor gender, with students regularly rating female instructors lower than male peers. Anne Boring, Kellie Ottoboni and Philip B. Stark argue the findings warrant serious attention in light of increasing pressure on universities to measure teaching effectiveness. Given the unreliability of the metric and the harmful impact these evaluations can have, universities should think carefully on the role of such evaluations in decision-making

Newtoning financial development with heterogeneous firms

Abstract: This article theoretically and empirically tests the link between financial constraints and the extensive (proportion of exporters) and intensive (volume of exports) margins of international trade. The article's main contribution is its macroeconomic analysis of this relationship, which is further reaching than the sector-based focus found in the current literature. It also presents new information on firm behavior under financial constraints. The paper develops a trade model with heterogeneous firms and shows that countries with a high level of financial development have a lower productivity cut-off above which firms export and a higher proportion of exporting firms. Nevertheless, financial development is not correlated with firms' export volumes once they become exporters. An empirical analysis is developed on the basis of an international trade database on 135 countries between 1994 and 2007. The empirical analysis estimates a two-step gravity equation using panel data and confirms the first theoretical proposition that finance has a positive impact on the extensive margin. However, the intensive margin results are striking. They find a negative relationship between financial development and trade flows, confirmed by all the sensitivity tests. Despite the positive effect of financial development found by the literature in some economic sectors, the macroeconomic impact on overall exports was negative during the analyzed period

Aberrant in Vivo T Helper Type 2 Cell Response and Impaired Eosinophil Recruitment in Cc Chemokine Receptor 8 Knockout Mice

Chemokine receptors transduce signals important for the function and trafficking of leukocytes. Recently, it has been shown that CC chemokine receptor (CCR)8 is selectively expressed by Th2 subsets, but its functional relevance is unclear. To address the biological role of CCR8, we generated CCR8 deficient (−/−) mice. Here we report defective T helper type 2 (Th2) immune responses in vivo in CCR8−/− mice in models of Schistosoma mansoni soluble egg antigen (SEA)-induced granuloma formation as well as ovalbumin (OVA)- and cockroach antigen (CRA)-induced allergic airway inflammation. In these mice, the response to SEA, OVA, and CRA showed impaired Th2 cytokine production that was associated with aberrant type 2 inflammation displaying a 50 to 80% reduction in eosinophils. In contrast, a prototypical Th1 immune response, elicited by Mycobacteria bovis purified protein derivative (PPD) was unaffected by CCR8 deficiency. Mechanistic analyses indicated that Th2 cells developed normally and that the reduction in eosinophil recruitment was likely due to systemic reduction in interleukin 5. These results indicate an important role for CCR8 in Th2 functional responses in vivo

Long term survival following the detection of circulating tumour cells in head and neck squamous cell carcinoma

Background Techniques for detecting circulating tumor cells in the peripheral blood of patients with head and neck cancers may identify individuals likely to benefit from early systemic treatment. Methods Reconstruction experiments were used to optimise immunomagnetic enrichment and RT-PCR detection of circulating tumor cells using four markers (ELF3, CK19, EGFR and EphB4). This method was then tested in a pilot study using samples from 16 patients with advanced head and neck carcinomas. Results Seven patients were positive for circulating tumour cells both prior to and after surgery, 4 patients were positive prior to but not after surgery, 3 patients were positive after but not prior to surgery and 2 patients were negative. Two patients tested positive for circulating cells but there was no other evidence of tumor spread. Given this patient cohort had mostly advanced disease, as expected the detection of circulating tumour cells was not associated with significant differences in overall or disease free survival. Conclusion For the first time, we show that almost all patients with advanced head and neck cancers have circulating cells at the time of surgery. The clinical application of techniques for detection of spreading disease, such as the immunomagnetic enrichment RT-PCR analysis used in this study, should be explored further
