8. Regulation by Reputation? Intermediaries, Labor Abuses, and International Migration, with Niharika Singh, Accepted, The Review of Economics and Statistics
Media: [VoxDevTalks (Podcast)] [ND News] [Medium] [Daily Mirror]
Abstract: Migrant workers and prospective employers rely on intermediaries to facilitate complex, lucrative, and often risky labor market matches. However, if information frictions obscure their reputation, intermediaries may have little reason to invest in the quality of their placements. Using data on over 1.5 million Sri Lankan migrants to the Gulf region, we test whether an intermediary rating program designed to ease information frictions can improve placement quality. The regulator first announced the rating criteria and then publicly revealed a rating. Agencies eligible for the program—especially previously under-performing agencies—invest in the rating criteria and are less likely to exit the market. Migrants placed by these agencies receive higher salaries, are matched with less abusive employers, and receive better non-wage amenities even prior to the ratings being revealed. Once revealed, higher ratings increase foreign demand, but elicit limited migrant response. Collectively, our results suggest the program induced intermediaries to improve placement quality by screening employment opportunities abroad.
7. Peer Pressure and Discrimination: Evidence from International Cricket, with Siddharth George, Forthcoming in The Journal of Law, Economics, and Organization
Media: [The Hindu] [ExBulletin] [Mint] [SportsEcon]
Data: [Data and Code]
Abstract: We study how peers affect in-group bias. Exploiting several umpiring reforms in international cricket matches —where two umpires make independent decisions in each other’s presence—we show that home-team umpires are less biased when working with a neutral colleague, i.e. one who is neither a national of the home nor the foreign team. This temporary debiasing is driven by the social pressure umpires feel to be impartial in the presence of neutral peers.Performance evaluation by visually non-salient monitors does not reduce bias, suggesting that physical presence is an important component of debiasing and peer influence.
6. Hiring Frictions and the Promise of Online Job Portals: Evidence from India, with Niharika Singh, and Gabriel Tourek, American Economic Review-Insights, Volume 5, Issue 4, December 2023
Media: [SGB Brief] [VoxDev]
Data: [Data and Code]
Abstract: Firms accustomed to hiring through networks may face sparse applicant pools, limiting the quantity or quality of hires. Online job portals expand their pool of potential employees, but such firms may be reluctant to trust workers outside their networks. We sample over 1,500 firms posting vacancies on an online job portal in India and randomly: (i) increase the size of their applicant pool, doubling the number of applicants; (ii) provide background verification services for their applicants; or (iii) both. Firms assigned to the combined treatment increase hiring from the portal relative to control and the individual treatments, which contributes to greater hiring overall. The hires from the portal are good matches as measured by employee retention after six months. We show how combining the treatments can generate a complementarity when firms value both ability and trustworthiness, but place greater relative weight on the latter. Our results suggest the effectiveness of online job portals can be enhanced through the provision of screening tools that induce greater employer trust in job seekers.
5. Shackled to the Soil: Inherited Land, Cultural Norms, and Labor Mobility, The Journal of Human Resources, Volume 57, Issue 2, Spring 2022
Media: [Harvard Business Review] [Dawn]
Data: [Data and Code] [Raw Data]
Abstract: The inheritance of wealth promotes occupational choice, but may restrict it where its use is constrained by limited markets and cultural norms. This paper investigates the effects of inheriting agricultural land in rural India and finds that while larger inheritances, on average, increase future household consumption, first-born sons do not experience these gains. For first-borns, inheriting land reduces urban migration and entry into non-agricultural work. In contrast, inheriting land does not influence occupational choice or migration for latter-born sons. I attribute these differences, in part, to a cultural norm of parental support incumbent on first-borns and its interaction with inherited land. Patrilineal Hindu inheritance customs, whereby sons inherit an equal amount of their parents’ land, motivate sibling sex composition as an instrument for land. In support of instrument exogeneity, I find no reduced form effects for individuals with landless parents.
4. Understanding Adverse Outcomes in Gulf Migration: Evidence from Administrative Data from Sri Lanka, with Alison Lodermeier, International Migration Review , Volume 56, Issue 1, 2022
Abstract: For many in South Asia, international migration to the Gulf countries provides access to lucrative employment opportunities without domestic comparison. Yet higher wages in Gulf countries are often coupled with poor working conditions, employer malpractice, and abuse. We utilize a unique administrative dataset on Sri Lankan migrant workers and complaints made by them to Sri Lankan Consulates to analyze the prevalence of workplace abuse and employer malpractice along this complex supply chain. Our analysis reveals that Sri Lankan migrants are systematically exposed to fraud and abuse that can, in part, be attributed to factors specific to the local recruitment agency who placed them. Understanding why recruitment agencies systematically differ in the quality of their placements may inform regulatory policy aimed at reducing the risks faced by migrants in destination countries.
3. Seeking the Treated: The Impact of Mobile Extension on Peer Information Exchange in India, Journal of Development Economics, Volume 153, November, 2021
Media: [VoxDev] [Ideas4India]
Data: [Data and Code]
Abstract: Do Information and Communications Technologies (ICTs) ‘disrupt’ in-person peer interactions that generate and spread local knowledge? To investigate, I randomize access to a mobile phone-based agricultural extension service and find that while it reduces reliance on peer agricultural advice, it does not crowd-out peer interactions. Instead, treated farmers are more likely to recommend inputs to their peers, who, in turn, prioritize interacting with them. Consequently, exposure to the treatment, directly or via peers, increases willingness-to-pay for the service. Overall, evidence on complementarities between treated respondents suggest ICT-based services may encourage peer interactions and technology diffusion at scale.
2. ‘Mobile’izing Agricultural Advice: Technology Adoption, Diffusion, and Sustainability, with Shawn Cole, The Economic Journal , Volume 131, Issue 633, January 2021, p. 192–219
Media: [JPAL Case Study] [Financial Times] [CEGA]
Data: [Data and Code]
Abstract: Mobile phones promise to bring the ICT revolution to previously unconnected populations. A two-year study evaluates an innovative voice-based ICT advisory service for smallholder cotton farmers in India, demonstrating significant demand for, and trust in, new information. Farmers substantially alter their sources of information and consistently adopt inputs for cotton farming recommended by the service. Willingness to pay is, on average, less than the per-farmer cost of operating the service for our study, but likely exceeds the cost at scale. We do not find systematic evidence of gains in yields or profitability, suggesting the need for further research.
1. Field Comparisons of Incentive-Compatible Preference Elicitation Techniques, with Shawn Cole, Daniel Stein, and Jeremy Tobacman, Journal of Economic Behavior & Organization, Volume 172, April 2020, p.33-56
Abstract: Knowledge of consumer demand is important for firms, policy-makers, and economists. One common tool for incentive-compatible demand elicitation, the Becker-DeGroot-Marschak (BDM) mechanism, has been widely used in laboratory settings but rarely evaluated for reliability at large scale in the field. In two field experiments (for a new agricultural information service and rainfall index insurance) we compare demand curves estimated from BDM implementations with demand curves estimated from choices at individually randomized fixed prices. In the test (for an agricultural information service) we obtain demand curves from BDM and fixed prices that align closely and are unable to reject equivalence of the demand curves. For the second test (of rainfall index insurance) the results are mixed, with the distributions lining up well at certain points of the demand curve and deviating at others. Overall, we find no evidence for systematic bias. Our evidence suggests that a ‘reframed’ version of BDM that uses discrete prices may minimize non-standard bidding behavior and is well suited to future experimental work in low-literacy environments.

9. The Grass is Not Always Greener: The Effects of Local Labor Market Information on Search and Employment, with Niharika Singh (Notre Dame)
Status: Under Review
Abstract: We examine how the provision of local labor market information shapes search and employment for job seekers in India. We randomly assign a group of job seekers to receive truthful information about the number and attributes of either job postings, applicants, or both for their preferred city and occupation on an online job portal. Treated respondents receiving any local labor market information are 10.2% more likely to be employed than control respondents seven months later. This overall effect varies considerably by baseline employment status and labor market beliefs. Among the initially employed, treated respondents are less likely to search off the portal, but are more likely to be employed because they remain in their (baseline) jobs. In contrast, among the initially unemployed, treated respondents are more likely to search across all methods, but only those with less optimistic labor market beliefs accept offers and are more likely to be employed. Our results are consistent with respondents inferring poor job prospects from the information treatments and show how access to local labor market information can reduce frictional unemployment.
10. Present Mothers, Absent Children? The Effects of Migration Restrictions in Sri Lanka, with Alison Lodermeier (Brown) and Paul Shaloka (EEOC)
Status: Draft available upon request (Updated, March, 2024)
Abstract: International migration offers access to lucrative but, often risky, labor market opportunities. Concerns about migrant abuse have led some sending-country governments to impose sweeping restrictions on migration with potentially important welfare consequences to would be migrants. We study a policy implemented by the Sri Lankan government in 2013 that restricted women’s migration opportunities both because of their own age and the age of their children. The ban’s intent was to reduce the potentially harmful costs of migrant mothers who leave young children behind. We find that the policy drastically reduced female migration to the Gulf region, suggesting strong compliance with the ban. Second, we find that households subject to the ban experience a reduction in remittance income lowering household consumption. Mothers subject to this ban reduce their fertility— an effect driven by behavioral response to the ban as opposed to compositional changes resulting from returning mothers and those restricted by the ban. The reform does not improve child outcomes. Rather, children in households affected by the ban are less likely to report attending school and have fewer years of education.
11. Fraternity or Fracture? National Identity, Religious Minorities, and Communal Violence in India with Layton Hall (ND)
Status: Draft available upon request (Updated, Feb, 2024)
Abstract: Nation states offer a cohesive identity to a diverse citizenry by minimizing their differences and elevating their commonality. While collective success can strengthen national identity, collective adversity can unravel it. We study the interplay between communal violence, religious, and national identity, by examining a sporting rivalry of unparalleled geopolitical consequence: international cricket matches between India and Pakistan. When India loses to Pakistan, we find a seven-fold increase in rioting in Indian districts with a significant Muslim minority. In contrast, Indian cricketing losses against other countries do not incite communal violence. Our results underscore the fragility of identity and its importance in influencing social cohesion.
12. Agricultural Extension, Technology Adoption and Information Spillovers: Evidence from a Cluster Randomized Experiment, with Shawn Cole (HBS), Raissa Fabregas (UT-Austin) and Hee Kwon Seo (Chicago-GSB)
Status: Draft available upon request (Updated, January, 2024)
Abstract: Social learning is an important component of the process of technology diffusion. If actions are not perfectly observable, learning may instead require information sharing by word-of-mouth. This project presents results from cluster-randomized controlled trial of a mobile phone-based agricultural extension program in rural India. The intervention was implemented in a setting in which farmers were already participating in bi-weekly agricultural meetings in learning groups. The intervention was randomized at the village-level but with varying degrees of saturation at the learning group level. We find that the demand by farmers who were randomly invited to participate was high, and that their agricultural knowledge and practices changed one year later. However, untreated members of their agricultural group were no more likely to have higher knowledge scores nor change their agricultural practices and they were less likely to report that they relied on others for agricultural information. These results suggest that information spillovers may be small and, at least in some contexts, relying on farmers to discuss agricultural information with others might not be an effective strategy for technology diffusion.
