On the interpretation of World Values Survey trust question - Global expectations vs. local beliefs

How should we interpret the World Values Survey (WVS) trust question? We conduct an experiment in India - a low trust country - to correlate the WVS-trust question with trust decision in an incentivized Trust Game. Evidence supports findings from one strand of the fractured literature: the WVS-trust question captures expectations about others’ trustworthiness. We further show that the WVS-trust question correlates with stable beliefs about how trustworthy people in general are. However, when subjects go through a treatment induced negative experience, WVS-trust question does not capture the immediate fluctuation in belief about trustworthiness anymore. One implication of our study is that survey based methods may not be appropriate to measure beliefs induced by a short term psychological perturbation.

Self Confidence Spillovers and Motivated Beliefs

Is success in a task used strategically by individuals to motivate their beliefs prior to taking action in a subsequent, unrelated, task? Also, is the distortion of beliefs reinforced for individuals who have lower status in society? Conducting an artefactual field experiment in India, we show that success when competing in a task increases the performers’ self-confidence and competitiveness in the subsequent task. We also find that such spillovers affect the self-confidence of low-status individuals more than that of high-status individuals. Receiving good news under Affirmative Action, however, boosts confidence across tasks regardless of the caste status.

Endowment Effects in the Field: Evidence from India’s IPO Lotteries

We study a unique field experiment in India in which 1.5 million stock investors face lotteries for the random allocation of shares. We find that the winners of these randomly assigned initial public offering (IPO) lottery shares are significantly more likely to hold them than lottery losers 1, 6, and even 24 months after the random allocation. This finding strongly evokes laboratory findings of an “endowment effect” for risky gambles, and persists in samples of highly active investors, suggesting along with additional evidence that this behaviour is not driven by inertia alone. The effect decreases as experience in the IPO market increases, but remains even for very experienced investors. Leading theories of the endowment effect based on reference-dependent preferences are unable to fully explain these and other findings in the data.

Do non-monetary prices target the poor? Evidence from a field experiment in India

This paper uses willingness to pay data from a field experiment in India to study targeting health products to the poor, using monetary prices and non-monetary prices (time costs). I model demand for the product at monetary and non-monetary prices. The model illustrates that monetary prices screen out the poor and that whether non-monetary prices screen out the non-poor is theoretically ambiguous because of opposing income and substitution effects. I find monetary prices select richer households and non-monetary prices do not provide strong selection on income. Both the poor and non-poor appear very elastic in the non-monetary price because of the high value of time in home production. I evaluate the problem of a principal with a fixed budget whose objective places some weight on coverage and some weight on targeting. Despite better targeting with non-monetary prices, the principal optimally chooses a monetary price for a large range of parameters.

Leveraging Patients' Social Networks to Overcome Tuberculosis Underdetection: A Field Experiment in India

Peer referrals are a common strategy for addressing asymmetric information in contexts such as the labor market. They could be especially valuable for increasing testing and treatment of infectious diseases, where peers may have advantages over health workers in both identifying new patients and providing them credible information, but they are rare in that context. In an experiment with 3,182 patients at 128 tuberculosis (TB) treatment centers in India, we find peers are indeed more effective than health workers in bringing in new suspects for testing, and low-cost incentives of about $US 3 per referral considerably increase the probability that current patients make referrals that result in the testing of new symptomatics and the identification of new TB cases. Peer outreach identifies new TB cases at 25%-35% of the cost of outreach by health workers and can be a valuable tool in combating infectious disease.

Determining the Extent of Statistical Discrimination: Evidence from a Field Experiment in India

In order to determine the relative size of taste-based and statistical discrimination, we develop a simple model to distinguish these two theories. We then test the model's predictions of caste-based discrimination by conducting a field experiment that elicits patients' rankings of physicians of different castes and years of experience in the healthcare market in India. We also run a survey and conduct lab-in-the-field experiments to measure patients' attitudes towards different caste groups. We find that 47 to 80 percent of patients statistically discriminate physicians. The overwhelming size of statistical discrimination has important implications for the use of Affirmative Action policies in India.

Using Social Connections and Financial Incentives to Solve Coordination Failure: A Quasi-Field Experiment in India's Manufacturing Sector

Production processes are often organized in teams, yet there is limited evidence on whether and how social connections and financial incentives affect productivity in tasks that require coordination among workers. We simulate assembly line production in a lab-in-the-field experiment in which workers exert real effort in a minimum-effort game in teams whose members are either socially connected or unconnected and are paid according to the group output. We find that group output increases by 18% and coordination improves by 30-39% when workers are socially connected with their co-workers. Connected groups also coordinate better when we introduce a lump sum bonus, suggesting that financial and social incentives can be complementary in this setting. These findings can plausibly be explained by trust between co-workers in socially connected teams.

Reshaping Adolescents’ Gender Attitudes: Evidence from a School-Based Experiment in India

Societal norms about gender roles contribute to the economic disadvantages facing women in many developing countries. This paper evaluates a school-based intervention in India that engaged adolescents in classroom discussions about gender equality for two and a half years with the goal of eroding their support for restrictive gender norms. Using a randomized controlled trial, we find that the program made attitudes 0.18 standard deviations more supportive of gender equality, or, equivalently, converted 16% of participants' regressive views. In addition, self-reported behavior became more aligned with progressive gender norms, particularly among boys. The effects observed in the short run were still present two years after the program had ended.

The Causal Mechanism of Financial Education: Evidence From Mediation Analysis

This paper uses a field experiment in India and mediation analysis to investigate the causal mechanisms between financial education and financial behavior. Focusing on the mediating role of financial literacy, we propose a broader definition of financial knowledge that includes three dimensions: numeracy skills, financial awareness, and attitudes towards personal finance. We then employ causal mediation analysis to investigate the proportion of the treatment effect that can be attributed to these three channels. Strikingly, we find that numeracy does not mediate any effects of financial education on financial outcomes. For simple financial actions such as budgeting, both awareness and attitudes serve as pathways, while for more complex financial activities such as opening a savings account, attitudes play a more prominent role---though these patterns appear to be sensitive to confounding. We also compare our mediation analysis results to other empirical techniques that have been typically used to study mechanisms, and we discuss how mediation analysis differs from these approaches.

Can incentives improve survey data quality in developing countries?: results from a field experiment in India.

We report results of an experiment designed to assess whether the payment of contingent incentives to respondents in Karnataka, India, impacts the quality of survey data. Of 2276 households sampled at the city block level, 934 were randomly assigned to receive a small one-time payment at the time of the survey, whereas the remaining households did not receive this incentive. We analyse the effects of incentives across a range of questions that are common in survey research in less developed countries. Our study suggests that incentives reduced unit non-response. Conditionally on participation, we also find little impact of incentives on a broad range of sociodemographic, behavioural and attitudinal questions. In contrast, we consistently find that households that received incentives reported substantially lower consumption and income levels and fewer assets. Given random assignment and very high response rates, the most plausible interpretation of this finding is that incentivizing respondents in this setting may increase their motivation to present themselves as more needy, whether to justify the current payment or to increase the chance of receiving resources in the future. Therefore, despite early indications that contingent incentives may raise response rates, the net effect on data quality must be carefully considered.

The Impact of Maternal Literacy and Participation Programs: Evidence from a Randomized Evaluation in India

Using a randomized field experiment in India, we evaluate the effectiveness of adult literacy and parental involvement interventions in improving children's learning. Households were assigned to receive either adult literacy (language and math) classes for mothers, training for mothers on how to enhance their children's learning at home, or a combination of the two programs. All three interventions had significant but modest impacts on childrens math scores. The interventions also increased mothers' test scores in both language and math, as well as a range of other outcomes reflecting greater involvement of mothers in their children's education.

Information strategies for energy conservation: A field experiment in India

Little is known about the effectiveness of information strategies on energy conservation in developing countries. In this study, we conduct a field experiment in an apartment complex in India to test how information about electricity usage impacts the electricity consumption of urban middle class households. Our results, based on fifteen-minute electricity readings over an academic year, show that non-monetary messages that framed electricity consumption in terms of environmental and health impacts were more effective than messages emphasizing the monetary savings of reducing electricity consumption. Households in the environmental/health group accessed the online energy-monitoring dashboard more frequently and reduced their electricity usage by 18.4% relative to the control group. Households in the monetary group did not significantly alter their usage. These results about revealed preferences are contrasted with stated preferences disclosed in a survey of urban Indians who describe money, not health, as the main motivation for energy conservation. Our findings have important implications for the development non-monetary strategies for energy conservation in developing countries.

DO PRIVATE TUTORS ENHANCE ENGLISH LANGUAGE ABILITY? REGRESSION DISCONTINUITY EVIDENCE FROM A POLICY EXPERIMENT IN INDIA

ABSTRACTEmpirical evidence has shown that returns to English language ability are substantial in India. Research has also focused on the impact of private tutoring in the context of developing economies to find evidence that remedial teaching leads to better student achievement and higher test scores. In this paper I analyze whether private tutoring helps in developing English language ability. Simple OLS estimates suggest statistically significant effects but estimated coefficients are rather small at 0.2 percentage points. Presence of confounders and selection bias may potentially understate the true effects of private tutoring on English language ability. To address this issue, I exploit a unique policy experiment in India in a regression discontinuity framework to identify cohorts eligible for private tutoring and compare their outcomes to the ineligible. I use this potentially exogenous policy variation as an instrument for private tutoring and find significant increases in English language ability estimated at 16 percentage points which is much larger than the simple OLS effects. Since standard academic curriculum is not directed towards improving foreign language ability, private tutoring as an input in the education production function seems to offer high marginal returns. From a policy perspective, this implies that private tutoring should be encouraged for enhancing English ability even though there are concerns that this provides disincentives for teachers to teach in school.

Do Rural Migrants Divide Ethnically in the City? Evidence from an Ethnographic Experiment in India

AbstractDespite rapid urbanization across the Global South, identity politics within rural‐urban migrant communities remains understudied. Past scholarship is divided over whether village‐based ethnic divisions will erode or deepen within diverse poor migrant populations. I assess these divergent predictions through an ‘ethnographic survey experiment’ (N=4,218) among unique samples of poor migrants in India. Contra conventional expectations, I find intra‐class ethnic divisions are neither uniformly transcended nor entrenched across key arenas of migrant life. Instead, I observe variation consistent with situational theories predicting ethnic divisions will be muted only in contexts triggering a common identity among migrants. I pinpoint urban employers and politicians as these triggers. Poor migrants ignore ethnic divisions when facing these elites, who perceive and treat them in class terms. However, migrants remain divided in direct interactions with each other. These bifurcated findings imply poor migrants may be available for both class‐based and ethnic mobilization in the city.

Unpacking sustainabilities in diverse transition contexts: solar photovoltaic and urban mobility experiments in India and Thailand

It is generally accepted that the concept of sustainability is not straightforward, but is subject to ongoing ambiguities, uncertainties and contestations. Yet literature on sustainability transitions has so far only engaged in limited ways with the resulting tough questions around what sustainability means, to whom and in which contexts. This paper makes a contribution to this debate by unpacking sustainability in India and Thailand in the context of solar photovoltaic and urban mobility experimentation. Building on a database of sustainability experiments and multicriteria mapping techniques applied in two workshops, the paper concludes that sustainability transition scholarship and associated governance strategies must engage with such questions in at least three important ways. First, there is a need for extreme caution in assuming any objective status for the sustainability of innovations, and for greater reflection on the normative implications of case study choices. Second, sustainability transition scholarship and governance must engage more with the unpacking of uncertainties and diverse possible socio-technical configurations even within (apparently) singular technological fields. Third, sustainability transition scholarship must be more explicit and reflective about the specific geographical contexts within which the sustainability of experimentation is addressed.

Learning to Manage: A Field Experiment in the Indian Startup Ecosystem

Why do some entrepreneurs thrive while others fail? We explore whether the advice entrepreneurs receive about people management influences their firm's performance. We conducted a randomized field experiment in India with 100 high-growth technology firms whose founders received in-person advice from other entrepreneurs who varied in their managerial style. We find that entrepreneurs who received advice from peers with an active approach to managing people–instituting regular meetings, setting goals consistently, and providing frequent feedback to employees–grew 28% larger and were 10 percentage points less likely to fail than those who got advice from peers with a passive people-management approach two years after our intervention. Entrepreneurs with MBAs or accelerator experience did not respond to this intervention, suggesting that formal training can limit the spread of peer advice.

Insecticidal effects of deltamethrin in laboratory and field populations of Culicoides species: how effective are host-contact reduction methods in India?

BackgroundBluetongue virus (BTV) is transmitted by Culicoides biting midges and causes bluetongue (BT), a clinical disease observed primarily in sheep. BT has a detrimental effect on subsistence farmers in India, where hyperendemic outbreaks impact on smallholdings in the southern states of the country. In this study, we establish a reliable method for testing the toxic effects of deltamethrin on Culicoides and then compare deltamethrin with traditional control methods used by farmers in India.ResultsEffects of deltamethrin were initially tested using a colonised strain of Culicoides nubeculosus Meigen and a modified World Health Organisation exposure assay. This method was then applied to field populations of Culicoides spp. in India. The field population of C. oxystoma in India had a greater LC50 (0.012 ± 0.009%) for deltamethrin than laboratory-reared C.nubeculosus (0.0013 ± 0.0002%). Exposure of C. nubeculosus to deltamethrin at higher ambient temperatures resulted in greater rates of knockdown but a lower mortality rate at 24 h post-exposure. Behavioural assays with C. nubeculosus in WHO tubes provided evidence for contact irritancy and spatial repellence caused by deltamethrin. The field experiments in India, however, provided no evidence for repellent or toxic effects of deltamethrin. Traditional methods such as the application of neem oil and burning of neem leaves also provided no protection.ConclusionsOur study demonstrates that field-collected Culicoides in India are less susceptible to deltamethrin exposure than laboratory-bred C. nubeculosus and traditional methods of insect control do not provide protection to sheep. These low levels of susceptibility to deltamethrin have not been recorded before in field populations of Culicoides and suggest resistance to synthetic pyrethrioids. Alternative insect control methods, in addition to vaccination, may be needed to protect Indian livestock from BTV transmission.

Impact of Third Party Audits on Compliance and Corruption: Evidence Using a Policy Experiment

Using a policy experiment in India, we examine the impact of a third party audit on tax compliance. Employing the generalized difference-in-difference methodology, we find that growth in tax payment is 58 percentage points higher under a regime with no third party audit. The fact that the differential growth in tax is negatively associated with differential growth in discretionary expenses and also absence of any real growth of treated firms, suggestively indicate collusion and corruption. Our results hold up-to a battery of placebo tests, absorption of time varying and time invariant unobservable factors and, display heterogeneity based on expected lines.
