PUBLIC TEACHING PACK SOURCE NOTES

Jason Hreha | Version 1.0 | 2026-09-05
Public-source reconstructions. The organizations are not claimed to have used
Behavioral Strategy, DRIVE, or BFA. Proposed tests are instructor analysis.
measurement-records.csv is entirely fictional and unrelated to the cited studies.
Source links do not grant reuse rights over the linked publications.

Keep source dates separate from the earlier events they describe.
The student and worked packets explain each source boundary in context.

BS-0007
Claim: Studies of M-PESA in Kenya report risk-sharing and poverty-related estimates under their respective study designs; these do not isolate removal of an environmental bottleneck as the sole mechanism.
Window: Multi-year (Kenya; study periods vary)
Title: Risk Sharing and Transactions Costs: Evidence from Kenya’s Mobile Money Revolution (Jack & Suri, 2014)
Link: https://doi.org/10.1257/aer.104.1.183
Title: The long-run poverty and gender impacts of mobile money (Suri & Jack, 2016)
Link: https://doi.org/10.1126/science.aah5309
Notes: This is not a micro-intervention story. The mechanism is context enablement (agent network + low-friction transfer rails) that unlocks existing remittance behaviors and changes constraints at scale.

BS-0079
Claim: M-PESA's public pilot accounts support candidate-use and operating-support hypotheses; they do not establish a representative paid first-use or repeat-opportunity rate.
Window: Pilot began 11 October 2005 and officially ended 1 May 2006; source publication dates differ from event dates
Title: M-PESA: Mobile Money for the Unbanked (Hughes and Lonie, 2007)
Link: https://www.gsma.com/mobilefordevelopment/wp-content/uploads/2012/06/innovationsarticleonmpesa_0_d_14.pdf
Title: Economic empowerment through mobile: WRI review of the 2006 setting (Vodafone CR dialogues)
Link: https://assets.ctfassets.net/q7ob9vms4z5k/3SiDxKfcGaiWbYiMwI5QyJ/44fb2dfd89e3bc89b93085ea5220f202/Vodafone_Group_CR_Dialogue_pages.pdf
Title: M-Pesa: creating the leading mobile money service (Michael Joseph, tenth-anniversary retrospective)
Link: https://www.vodafone.com/news/newsroom/digital-society/m-pesa-created
Notes: Source dates and units must remain explicit. The 2006-setting report cites an April pilot review; the 2007 paper reconstructs development; Joseph's later account is retrospective. New teaching decisions, rules and tests are instructor proposals. These sources do not establish historical DRIVE/BMF/BFA use or validate those methods.

BS-0080
Claim: Instagram's early public history supports a qualified reconstruction of product focus and problem selection; it supplies no isolated causal estimate for the pivot.
Window: 2010 product decision; founder talk on 11 May 2011; later engineering account in October 2015
Title: From Stanford to Startup: Kevin Systrom and Mike Krieger (Stanford, 11 May 2011)
Link: https://stvp.stanford.edu/av/stanford-startup-entire-talk
Title: Transcript of the founders' Stanford talk
Link: https://stvp.stanford.edu/node/12536/printable/print
Title: Instagram prelaunch product preview (TechCrunch, 20 September 2010)
Link: https://techcrunch.com/2010/09/20/instagram/
Title: Five Years of Building Instagram (Mike Krieger, 7 October 2015)
Link: https://www.wired.com/2015/10/five-years-of-building-instagram/
Notes: No raw feature-use comparison, population denominator or intervention control was recovered. The talk and transcript are one source. Teaching options and categorical BFA labels are present-day analyses, not company methods or historical measurements. Inspected on 5 September 2026.

BS-0081
Claim: The NAO's 2019 Verify audit identifies gaps between reported identity-registration success and the user's complete government-service journey.
Window: Performance through February 2019; NAO report published 5 March 2019
Title: Investigation into Verify (National Audit Office, 5 March 2019)
Link: https://www.nao.org.uk/reports/investigation-into-verify/
Title: Full report, printed page 16, paragraphs 1.16 and 1.17
Link: https://www.nao.org.uk/wp-content/uploads/2019/03/Investigation-into-verify.pdf
Title: NAO findings release (5 March 2019)
Link: https://www.nao.org.uk/press-releases/investigation-into-verify/
Notes: The measure excludes departures before provider selection and ends before use of the intended service is established. The projection is not a control group. The classroom decision occurs after the audit; its workflow, study design and recommendations are original instructional proposals. No framework use or independent method validation is established. Inspected on 5 September 2026.

BS-0082
Claim: Wikimedia's Growth experiment found improved first-edit activation; the reported increase in retained editors was inferred through activation rather than directly detected.
Window: Accounts registered November 21, 2019 to May 14, 2020; November 2020 analysis
Title: Growth/Personalized first day/Newcomer tasks/Experiment analysis, November 2020 (Wikimedia Growth team)
Link: https://www.mediawiki.org/wiki/Growth/Personalized_first_day/Newcomer_tasks/Experiment_analysis,_November_2020
Notes: Randomized feature-bundle comparison; accounts toggling features were excluded. Unreverted is a quality proxy. Page revision January 9, 2025, oldid 6960794, inspected September 5, 2026. No evidence of DRIVE/BMF/BFA use or validation.

BS-0083
Claim: Six California outreach experiments found no detected increase in tax filing or EITC claiming from the tested letters and text messages.
Window: Spring 2018 and spring 2019, addressing tax years 2017 and 2018
Title: Can Nudges Increase Take-Up of the EITC? Evidence from Multiple Field Experiments (Linos et al., November 2022)
Link: https://www.aeaweb.org/articles?id=10.1257/pol.20200603
Title: Can Nudges Increase Take-Up of the EITC? Evidence from Multiple Field Experiments (November 2020 working paper)
Link: https://www.capolicylab.org/wp-content/uploads/2020/11/Increasing-Take-Up-of-the-Earned-Income-Tax-Credit.pdf
Notes: Preserve each trial's sample and comparator; do not sum overlapping samples as unique households. An offer of help is not received hands-on assistance. These null treatment results do not establish that filing is an infeasible target. Journal abstract and working-paper methods inspected September 5, 2026. No method-use or framework-validation claim.
