  • Does the facial image matter? An experiment on the willingness to disclose private information.
    Last registered on May 16, 2021

    In the age of information technology and big data, how people evaluate their personal data is a basic and important issue that has not been fully explored. Firstly, we want to find out whether people’s willingness to disclose privacy information with or without facial image are significantly different. So, we will measure the willingness to accept (WTA) the uploading of a screenshot of their current "Epidemic Prevention Itinerary Card" or "Personal Health Code" (both of them contain private information) , whose main difference is whether include a facial image. Then, we will test the “privacy paradox” by comparing the participants’ WTAs in a hypothetical environment with those in a real-incentive environment.

  • Hiring Prospects of Online Education: Evidence from a Randomized Field Experiment
    Last registered on May 15, 2021

    The present research is intended to assess the employment premium of online specialization certificates by way of a randomized field experiment. The project draws upon labor market discrimination literature and speaks to the growing interest in the future of online education opportunities. The study’s results will inform job candidates as well as MOOC platforms of potential benefits of online certifications as from the potential employers’ standpoint.

  • A sequential and adaptive experiment to increase the uptake of long-acting reversible contraceptives in Cameroon
    Last registered on May 14, 2021

    Cameroon exhibits a high and non-decreasing level of maternal mortality (roughly 600 per 100,000 live births), partially related to its relatively high total fertility rate (roughly 4.6). Survey evidence furthermore suggests that a significant fraction of these pregnancies is unwanted or considered mistimed by the mother, especially among females aged 15-19. Despite this, the rate of utilization of family planning (FP) is low: e.g. only 48% of sexually active unmarried women use any form of (modern) contraception, or MC, and even then, it is primarily condoms. The use of LARCs (long-acting reversible contraceptives, i.e. the IUD and implant) is less than 1% according to the most recent Demographic Health Survey. We propose to use an integrated behavioral science approach to increase...

  • Pledges and charitable giving
    Last registered on May 14, 2021

    The study examines the effects of reminders on following though on a donation pledge and continued donation. We partner with a charity to conduct a field experiment to test the effects of reminders on donation rates and donation amounts in the short and long run.

  • Why patients abandon treatment?
    Last registered on May 14, 2021

    A large share of patients with chronic diseases abandon treatment. Although there is a strong presumption that this hurts their health, we were unable to find a well powered study that estimates causal effects of abandonment on health. Our study has several main objectives. First, to estimate the causal effect of staying in treatment longer, on the health of diabetic patients. In particular on their HbA1c levels, but also on their knowledge, their expectations of treatment effectiveness and of their cost of complying with treatment. Second, to find whether it is more cost effective to incentivize clients to stay ex-ante for staying, or to bring the abandoners back through a subsidy ex-post after they abandon. The later one may be more well targeted, but the former may create dynamic in...

  • Legal mandates, information, and political representation of women: Evidence from Gender Quotas in Chile
    Last registered on May 14, 2021

    Over a hundred countries use gender quotas in politics to increase female representation. Yet, when quotas apply only on party candidate lists, parties often strategically respond, resulting in female representation being at the lower end of what is compatible with quotas (Esteve-Volart and Bagues, 2012). This project will exploit an electoral setting in Chile where the party's ability to manipulate the fraction of women elected through candidate choice is limited by law. Using a randomized information campaign, which consists of sending letters to voters from randomly selected voting booths, I will examine whether informing voters about the law to ensure gender parity impacts voter candidate choice and partisan preferences. The aim is to use the findings to evaluate the underlying caus...

  • A Scientific Approach to Entrepreneurship and Innovation: A Field Experiment in China
    Last registered on May 14, 2021

    Making decisions under uncertainty is at the core of entrepreneurship. However, evidence suggests that entrepreneurs lack a method to make decisions under uncertainty. Prior work shows that entrepreneurs can improve their ability to make these decisions by adopting a scientific approach, i.e., validating entrepreneurial ideas as scientists act. Specifically, when entrepreneurs frame and identify the problem, articulate theories, define clear hypotheses, conduct rigorous tests to confirm or disconfirm these hypotheses, and make decisions based on these tools, they make better performance. Building on prior research conducted in Italy, the United Kingdom, India, and Tanzania, this study conducts a randomized controlled trial (RCT) which provides training to entrepreneurs, and explores the...

  • Job Characteristics and Attraction to Public Sector Employment: The Moderating Effects of Public Service Motivation and Self-Efficacy
    Last registered on May 14, 2021

    How can public sector organizations ensure and improve the performance of their services? One important factor is job design. We know that job characteristics have a sorting effect: Some individuals are more attracted to jobs involving particular job arrangements than other individuals are. Moreover, research shows that individuals’ public service motivation (PSM) and self-efficacy are significant predictors of work performance. We ask: Which job arrangements are most important for attracting these “high-performers”—people high in PSM and self-efficacy—to public sector employment? Using a within-subjects conjoint survey experimental design among a non-probability sample of US residents (n = 1,500), this study examines how the effects of eight particular job characteristics on job attra...

  • The Value of Recommender Systems
    Last registered on May 14, 2021

    In this project we run a longitudinal field experiment in order to decompose the mechanisms that drive the influence recommendation systems have on consumption choices in terms of their informational and product discovery value. Targeting a class of goods for which recommendations are ubiquitous -- movies --, we randomize the set of recommended movies on a movie-recommendation platform and compare outcomes to a control group of movies that holds fixed individuals' idiosyncratic preferences. We test for whether recommendations meaningfully affect consumption patterns and beliefs about products.

  • Evolve Digital - The adoption of new technology in small family businesses
    Last registered on May 14, 2021

    The trial seeks to identify a cost-effective, yet productivity-enhancing programme of peer-group learning for family business SMEs which can be replicated and run at scale. The experiment addresses a key problem faced by the long-tail of low-productivity businesses in England by seeking to reduce barriers to the adoption of digital technologies that have been demonstrated to increase productivity. By selecting family businesses with low rates of digital technology adoption and working with them in facilitated peer-groups the trial seeks to provide:
 - the demonstration of measurable improvements in intent to adopt productivity enhancing digital technologies 
- evidence of some adoption of the technologies before the end of the trial
 - in the longer term, measurable increases in pr...
