Behaviour & psychologyFriendship Network Social ReinforcementFully treated friendship networks produced a 0.46 standard deviation increase in knowledge (versus 0.28 SD for students with zero treated friends) and a 0.24 standard deviation increase in positive sexual attitudes (versus 0.04 SD for students with zero treated friends).RCTLabour & employmentInformal Network Substitution for Formal Reference LettersParticipants acquiring work experience and a reference letter were 7.9 percentage points less likely to submit a reference letter when applying for jobs (IV coefficient = -0.079, standard error = 0.110) and reduced the total number of times a reference letter was submitted by 0.381 times.RCTBehaviour & psychologyLanguage-Matched Peer MentorshipSenior-junior pairs engage in twice-weekly structured interactions for eight weeks focusing on practical guidance and bond-building activities; empirical impacts on labor market outcomes and mental health are forthcoming.RCTDevelopmentLocal Social Network Information DensityTwo-thirds (66%) of respondents identified at least one group member as family or a close friend, and over 50% reported regularly discussing private family and business matters with peers in their five-person group.RCTLabour & employmentNetwork Inequality PerpetuationInformal networks account for 30–60% of jobs in the US and 45% of jobs in the Kolkata labor sample, creating substantial long-run inequality risks across socio-demographic groups if uncountered by meritocratic screening.Expert TheoryLabour & employmentRandomized Saturation Design for Network SpilloversModerate transport subsidy saturation (40%) generated positive indirect spillovers on untreated neighbors, raising formal employment by 6.2 percentage points (p < 0.10) and permanent employment by 6.4 percentage points (p < 0.05); high saturation (90%) produced negative spillovers on permanent work (-6.8 percentage points, p < 0.01).RCTLabour & employmentReferral Quality Incentive Gap in Job NetworksUnder standard unincentivized conditions, male recommenders do not systematically refer the highest-quality candidates from their social networks; offering explicit financial performance incentives significantly increases the ability and test scores of referred job seekers.RCTDevelopmentSenior-Junior Mentoring and Social Support NetworkResearch is ongoing with results forthcoming; baseline parameters establish a 27 percent national female labor participation rate and over 75 percent annual factory turnover.RCTLabour & employmentSocial Job Network ExpansionAcquiring short-term work experience increased the probability of receiving any job referral by 22.2 percentage points (p < 0.05) and increased the overall social network index by 0.306 standard deviations (p < 0.10) over the 8-month follow-up period.RCTLabour & employmentSocial Network Expansion MechanismExperimentally induced short-term work experience increases the likelihood of hearing about a job opportunity through contacts met during the intervention by 22.2 percentage points (p < 0.05). It increases the standardized social network index by 0.306 standard deviations (p < 0.10).RCTEconomics (general)Social Network Risk-Sharing DistortionOver 35% of reported gifts and high-value loans occurred between relatives compared to only 2% between coworkers; unincentivized workers were 7 percentage points more likely to refer relatives (baseline <15%) than workers facing performance-contingent pay.RCTLabour & employmentInformal Social Network Search FrictionsBaseline survey results indicate that Yuva Parivartan graduates experience initial placement difficulties and disproportionately depend on personal social connections to find employment.Observational StudyLabour & employmentWorkplace Network Expansion for Family Planning InformationBaseline state survey revealed 40% female employment compared to 78% male employment; evaluation measures whether job expansion builds social networks that make family planning accessible and affordable.RCTDevelopmentSocial Network Spillover Assessment6,000 connected peers were enrolled and tracked alongside 2,000 primary participants, with empirical spillover results forthcoming.RCT
