Do the Long-term Unemployed Benefit from Automated Occupational Advice during Online Job Search, CEPR Discussion Paper DP17513, (R&R at Economic Journal)

In a randomized field experiment, we provide personalized suggestions about suitable alternative occupations to long-term unemployed job seekers in the UK. The suggestions are automatically generated, integrated in an online job search platform, and fed into actual search queries. Effects on the primary pre-registered outcomes of "finding a stable job" and "reaching a cumulative earnings threshold" are positive, are significant among those who searched at least once, and are more pronounced for those who are longer unemployed. Treated individuals include more occupations in their search and find more jobs in recommended occupations. 

Gender Diversity and Diversity of Ideas , VERSION 27 NOVEMBER 2023

Michèle Belot, Madina Kurmangaliyeva (ULB) and Johanna Luise Reuter (Linz)

Diversity in employee representation is often advocated for its potential to promote the diversity of ideas, and thereby innovation. In this study, we shed light on the phenomenon of 'idea homophily', which is a tendency to be more interested in ideas closer to one's own. We first document recent trends in the Economics Academic junior hiring showing that women specializing in traditionally male-dominated fields are faring significantly better than their counterparts in female-dominated fields and even outperform their male peers. We then examine the demand for ideas in a college educated population with an Online experiment involving 500 participants. We find substantial gender differences in which ideas people are choosing to engage with. Also, when decision-makers are predominantly male, incentives encouraging engagement with female ideas increase substantially their demand, but disproportionately in male-dominated fields. In contrast, incentives encouraging ideas in female-fields in general increase exposure to female ideas but do not lead to an over-representation of either gender conditional on field.

Bridging America's Divide on Abortion, Guns and Immigration: An Experimental Study, CEPR Discussion Paper 20258 (Link to Online Appendix), VERSION JULY 2022

Michèle Belot and Guglielmo Briscese

Americans appear increasingly polarized and unable to bridge ideological divides. We study individuals' willingness to engage with others who hold opposite views on  polarizing policies. Two thousand five hundred Americans are given the opportunity to listen to recordings of fellow countrymen and women expressing their views on immigration, abortion laws and gun ownership laws. We find that most Americans (more than two-thirds) are willing to listen to a view opposite to theirs, and a small fraction (ten percent) reports changing their views as a result. We also test whether emphasizing common grounds with those who think differently helps bridging views. We identify principles the vast majority of people agree upon: (1) a set of fundamental human rights, and (2) a set of simple behavioral etiquette rules. A random subsample of people are made explicitly aware they share common views, either on human rights or etiquette rules, before they have the opportunity to listen to different views.  We find that the treatments induce people to adjust their views towards the centre on abortion and immigration, relative to a control group, thus potentially reducing polarization.

Eliciting Time Preferences when Background Consumption and Income Vary, with Philipp Kicher and Paul Muller, forthcoming at AEJ Micro

We propose a simple method for eliciting individual time preferences without estimating utility functions even in settings where background consumption changes over time. It relies on lottery tickets with high rewards. In a standard intertemporal choice model high rewards decouple lottery choices from variation in background consumption. We validate our elicitation method experimentally on two student samples: one asked in December when their current budget is reduced by extraordinary expenditures for Christmas gifts; the other asked in February when no such extra constraints exist. We illustrate an application of our method with unemployed job seekers which naturally have income/consumption variation.


IZA DP No. 11814: How Wage Announcements Affect Job Search: A Field Experiment, published in AEJ Macro

Michèle Belot, Philipp Kircher, Paul Muller

We study how job seekers respond to wage announcements by assigning wages randomly to pairs of otherwise similar vacancies in a large number of professions. High wage vacancies attract more interest, in contrast with much of the evidence based on observational data. Some applicants only show interest in the low wage vacancy even when they were exposed to both. Both findings are core predictions of theories of directed/competitive search where workers trade off the wage with the perceived competition for the job. A calibrated model with multiple applications and on-the-job search induces magnitudes broadly in line with the empirical findings.

Changing Dietary Habits Early on in Life: A Field Experiment with Low Income Families, forthcoming in JPE Micro

Michèle Belot, Noemi Berlin, Jonathan James, Valeria Skafida

We conduct a field experiment to evaluate the extent to which dietary habits are malleable early on in childhood and later in life. We implement two treatments one that targets what people eat, the other that targets the timing and frequency of food intake. 285 low income families with young children were recruited and assigned either to a control group or one of the two treatments, each of them lasting for 12 consecutive weeks. In one treatment, families received food groceries at home for free for 12 weeks and were asked to prepare five specific healthy meals per week. In the other treatment, families were simply asked to reduce snacking and eat at regular times. We collected a range of measures of food preferences, dietary intake, as well as BMI and biomarkers based on blood samples. We find evidence that children's BMI distribution shifted significantly relative to the control group, i.e. they became relatively "thinner". We also find some evidence that their preferences have been affected by both treatments. On the other hand, we find little evidence of effects on parents. We conclude that exposure to a healthy diet and regularity of food intake possibly play a role in shaping dietary habits, but influencing dietary choices later on in life remains a major challenge.
