FEATURED NEW WP: “Gender Differences in the Choice of Major: The Importance of Female Role Models” with C. Porter (Heriot-Watt). December 2017. PDF here.
Abstract: We report results from a field experiment aimed at increasing the percentage of women majoring in economics by exposing students enrolled in principles of economics classes to carefully chosen career women who majored in economics -- our female role models. This is the first experiment of its kind to our knowledge, as it is the first to evaluate the impact that interacting with inspiring women other than classroom instructors may have on female students' choice of major. By randomizing classes that were offered and taught by the same instructors the previous year, we are able to employ a difference-in-differences estimation strategy. Our results suggest that, while the role model intervention had no impact on male students, it significantly increased female students' likelihood of expressing interest in the economics major (self-reported) and enrolling in intermediate microeconomics classes (administrative data), which we show are good predictors of majoring in economics. The intervention was especially effective on top-performing female students. Our data also show that the women that were impacted by the intervention were previously planning to major in fields with lower expected earnings, suggesting that our low-cost intervention could have a significant impact on the future income streams of the treated young women.

WORKING PAPERS AND WORK IN PROGRESS
“Motivating Whistleblowers” with J. Butler (LSU) and G. Spagnolo (SITE, Stockholm School of Economics). REVISED October 2017: PDF. R&R at Management Science.
We employ a novel laboratory experiment to investigate if and how monetary incentives and expectations of social approval or disapproval, and their interactions, affect the decision to blow the whistle against managers’ law-breaking behavior.
“Is more competition always better? An experimental study of extortionary corruption”, with D. Ryvkin (FSU). Revised October 2015. PDF. R&R at Economic Inquiry.
We conduct an extortionary bribery experiment where clients apply for a license from one of many available offices and officials can demand a bribe on top of the license fee. By manipulating the number of available offices and the size of search costs we are able to assess whether increasing competition among officials reduces extortionary corruption.

“Health Workers’ Behavior, Patient Reporting and Reputational Concerns: Lab-in-the-Field Experimental Evidence from Kenya”, with I. Mbiti (U of Virginia). IZA working paper, February 2018. PDF. Instructions of the lab-in-the-field experiment here.
We use lab-in-the-field experiments to examine the effectiveness of accountability systems that rely on patient reporting in Kenyan health clinics. We evaluate patients’ willingness to file complaints on service providers, and providers’ responsiveness to the possibility of receiving such complaints, when knowing that the number of received complaints would be disclosed to professional peers.
“Corrupt Police” with K. Abbink (Monash University) and D. Ryvkin (FSU). Coming soon.
We experimentally investigate the impact of police corruption on rule violations within a society. We then test and contrast the effectiveness of two anti-corruption policies. The first relies on the payment of small financial rewards to officers based on the crime rate observed within the society. The second relies on the payment of small rewards based on the bribery rate observed within the society.
“The Gender Leadership Gap: An Experiment” (working title) with P. Chakraborty (SMU). Coming soon.
Do women hesitate in becoming managers due to an aversion to creating inequality among workers and/or an aversion to the possibility of receiving negative judgment from workers? Do male and female managers have different leadership styles i.e. do they communicate, motivate, evaluate and penalize workers differently? Do workers respond differently to a male vis-à-vis a female manager? We address these questions by employing a novel laboratory experiment that simulates corporate decision-making, i.e., task allocations, promotions/demotions, motivations and evaluations.
