  • Nudges to improve learning and gender parity: Supporting parent engagement and Ghana’s educational response to Covid-19 using mobile phones
    Last registered on March 03, 2021

    While recent evidence from Brazil and Ivory Coast suggests that SMS messages to nudge parents' engagement in their children's education have large effects on educational outcomes, the Covid-19 pandemic raises additional concerns. In particular, learning deficits and school dropouts are likely to increase following school shutdowns, especially among vulnerable populations such as older girls who need to work to support their families or due to early marriage, childbearing and adolescent pregnancy. A further knowledge gap relates to the optimal period of exposure to the nudges, which is critical to scale-up. This study investigates whether sending nudges to parents can improve parental engagement in child education and broader development across child age groups and gender, in the low-res...

  • Bias in Child Maltreatment Reporting
    Last registered on March 03, 2021

    The purpose of this research is to study the implicit biases that may be present in child maltreatment reporting decisions. Participants in this study are randomly assigned to either the mandatory reporter condition or the permissive reporter condition. Participants will read a series of ten short vignettes detailing interactions between a parent and their child. They will then be asked to decide how likely they are to report the interaction to the authorities as suspected child abuse or neglect (definitely report, likely to report, unlikely to report, definitely not report). They will be asked to answer several demographic questions at the end of the survey.

  • Do saliency of extreme actions to secure a COVID-19 vaccine increase demand for the vaccine?
    Last registered on March 03, 2021

    This study aims to examine if saliency of extreme actions to secure a COVID-19 affects demand for the vaccine. Specifically, we will design an economic experiment to test the effect on vaccine demand from information about rich people jumping the line or information about vaccine hunters. We will use willingness-to-pay (WTP) for a service to facilitate the booking of vaccine appointments as a proxy for demand for the vaccine itself.

  • Job referrals and strategic network formation -- Experimental evidence from urban neighbourhoods in Ethiopia
    Last registered on March 03, 2021

    This experiment tests what influences the linking decisions between individuals through job referrals, and whether these social job networks are formed strategically. I randomly generate job opportunities for young job seekers from dense urban neighbourhoods in Addis Ababa, Ethiopia. Some participants are enabled to refer individuals from their neighbourhood to the same job, and I repeat this experiment for several rounds. Explanatory variables of interest are various referral treatment indicators, various measures of participants' network centrality, as well as dyadic characteristics of two individuals in the social networks. Outcomes of interest are a variety of characteristics of the referred worker, of referral indicators between two individuals, as well as on-the-job performance of...

  • Supporting Teacher Autonomy to Improve Education Outcomes in Brazil
    Last registered on March 02, 2021

    We provide experimental evidence from a program in Brazil that supports teachers, through a combination of technical assistance and a small grant, to autonomously develop and implement an innovative project aimed at engaging their students.

  • Endogenous Institutions: a network experiment in Nepal
    Last registered on March 02, 2021

    In developing countries where formal institutions are often weak, peer monitoring represents a natural mechanism for the enforcement of agreements. This paper studies the demand for monitoring and its effectiveness in sustaining cooperation across social groups. Mapping the social networks of 19 Nepali villages, we conduct an experiment to explore the role of the endogenous choice of monitors on cooperation. The paper shows that closely knit groups are 40% points less likely to choose a central monitor, while sparse groups tend to prefer a monitor who is highly central in the network. The democratic selection of monitoring improves cooperation by up to 22% compared to an exogenous assignment, but only in sparse groups. Further, we observe that in sparse groups the positive effect of e...

  • Opting For A Preferential Tax Regime – The Role Of Accountants And Long Term Incentives On Small Businesses’ Behaviour
    Last registered on March 02, 2021

    Hungarian small businesses have access to a preferential small business tax regime (SBT). SBT offers show term benefits with lower tax rates and easier administration relative to the general corporate tax regime. Additionally it has long term benefits through its cash-flow design, favouring firms who invest their profits. Despite their eligibility and potential gains, many firms do not opt for SBT. Previous trials showed that the tax authority can increase take-up rate by directly providing information on SBT to eligible firms. In this randomized field experiment we investigate two questions. Is targeting this messaging to firms, or their accountants effective; and is emphasizing long term benefits over short term benefits more effective. The results will shed light on small businesses'...

  • Impact of AI skills on job application outcomes: Evidence from a field experiment
    Last registered on March 02, 2021

    We investigate the demand of AI skills in real job applications with a correspondence experiment. We send fictitious job applications in response to real job postings for entry-level employees with a business administration background on UK-based online job boards, randomly varying whether the CVs include AI skills. First, we study the effect of these skills on the callback rate. Second, we investigate potential differences across three types of business administration jobs (marketing, HR and finance and accounting).

  • Can Information on School Attributes and Assignment Probabilities Direct Search and Choice? Evidence from Choice Platforms in Ecuador and Peru
    Last registered on March 02, 2021

    The main objective of this project is to study how the provision of information regarding available alternatives affects the search and application process of parents with and without non assignment risk on school choice platforms. Previous evidence has documented that there exist heterogeneous beliefs about assignment probabilities and these drive choice application behavior Kapor, Neilson and Zimmerman (2020). In addition, Arteaga, Kapor, Neilson and Zimmerman (2021) provides evidence that biased beliefs of assignment probabilities lead applicants to list too few options and that correcting these beliefs leads applicants to expand their list of options suggesting additional search was conducted in the process. Allende et al (2021) shows evidence of limited awareness of the set of pote...

  • Reference-Dependent Effort Provision under Heterogeneous Loss Aversion: Pre-Analysis Plan
    Last registered on March 02, 2021

    In this study, we design a two-stage experiment to test the comparative static predictions of a leading model of reference-dependent preferences. In particular, we derive predictions from Koszegi and Rabin (2006, 2007) (henceforth KR) for both loss averse and gain loving individuals, and demonstrate how inconclusive average treatment effects from prior studies could be confounded by heterogeneity in gain-loss preferences. We then prepend a first stage to the classic experimental tests of KR in the real effort domain (Abeler et al, 2011; Gneezy et al, 2017) intended to measure individual gain-loss preferences, and examine the difference in treatment effects by type in our second stage.
