Methods & evidenceActive Tracking Attrition MitigationAttrition was maintained at 3.4% to 7.7% across most study arms (except Vadodara Year 1 at 17-18% due to communal riots), with attritor pretest scores showing no significant difference between treatment and control groups.RCTMethods & evidenceHawthorne Effect Mitigation in Phone SurveysStandardized fortnightly phone surveys collected reliable longitudinal search data without generating detectable Hawthorne or priming effects, preserving true treatment-control contrast across survey rounds.Observational StudyDevelopmentHigh-Frequency Phone Panel MethodologyFortnightly phone surveys maintained low monthly attrition rates (ranging between 2% and 6%) and reliably captured short-run fortnightly spikes in search intensity (+12.5% during transport subsidy weeks) without generating Hawthorne measurement effects.Observational StudyMethods & evidenceHigh-Frequency Survey Recall ValidationDaily visits averaged 8.11 GH¢ cash in and 3.32 GH¢ cash out. Comparing monthly recall to aggregated daily data showed no statistically significant difference in revenue (p-value > 0.10, difference of -4.08 GH¢) or expenses (difference of 8.71 GH¢), proving that monthly recall surveys do not introduce strategic reporting bias in consulting evaluations, though daily data exhibited higher variance for record-keepers (squared difference 22,895 GH¢, p < 0.05).RCTMethods & evidenceIncentivized High-Frequency Micro-SurveysThe micro-survey protocol achieved a retention rate of 54% over 30 weeks while capturing 137,927 weekly survey observations verified through photo receipt submissions.RCTLabour & employmentResume-Survey Experience Measurement DiscrepancyWhile only 15% of respondents reported no prior work experience in self-reported survey modules, 35% lacked work experience on their submitted résumés, revealing a 20 percentage point discrepancy caused by infrequent résumé updates and differing worker definitions of suitable CV entries.Observational StudyFirms & operationsStandardized Management Scoring and Global Practice Stochastic DominanceDeveloping nations (Brazil, China, India) exhibit significantly lower average management scores, with their entire distribution of management practices stochastically dominated by firms in rich countries.Observational StudyEconomics (general)Trusted Enumerator Data Collection in Vulnerable Populations6-week rapid surveys by unfamiliar enumerators showed near-zero employment impacts (0.6 percentage points for cash, p = 0.296; control mean 4.9%), whereas 2-month ESO surveys revealed 5.2 percentage point employment gains for Syrian refugees (p = 0.017; control mean 9.1%), with significant job increases occurring just below the formal minimum wage.Observational Study
