Methods & evidenceBirthdate-Based Randomization DesignProduced balanced baseline demographic distributions across treatment and control groups while enabling evaluation of policy regime shifts.RCTBehaviour & psychologyCovert Market Choice Experiment FramingCovert framing successfully measured baseline discrimination where control group participants sacrificed goods worth nearly twice the median daily per capita food expenditure to avoid selecting transgender workers, while eliminating experimenter demand bias.RCTMethods & evidenceDual-Channel Branch and Intercept RecruitmentRetention rates remained highly balanced across recruitment channels (56% retained inside MTO branches vs. 52% retained in public areas), confirming observable baseline balance across gender (74% female), age (mean 35 years), and monthly income (55% above median).RCTFinance & microfinanceFinancial Incentive Encouragement for Low-Baseline Take-up RatesUnincentivized workshop participation yielded only 36 attendees out of 487 invited and 4 savings account sign-ups out of 438; adding financial incentives and revisits boosted final workshop participation to 38.9%–41.4% (p < 0.01) and micro-insurance take-up to 25.1%–28.0% (p < 0.01).RCTFirms & operationsPersistence of Management Practices Post-InterventionManagement practice adoption dropped by only 3 percentage points on average (from 63.4% to 60.4%) 12 months after consultants left, demonstrating that lean practice adoption creates permanent structural habit shifts.RCTEconomics (general)Upfront Unconditional Monetary Incentives in Survey Nonresponse ReductionThe upfront $10 cash incentive produced a 23% response rate compared to 16% for the conditional $50 check alone (t-statistic = 1.81, p-value = 0.08), helping raise the study's overall response rate to 46% across mailings.Observational Study
