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.RCT
