Replication Data and Code for: The Boundary Below Which Trust Cannot Sustain Cooperation in a Voluntary Collective Organization

Replication package for the manuscript 'The Boundary Below Which Trust Cannot Sustain Cooperation in a Voluntary Collective Organization' (David M. Dror and Gerard Duru). The deposit makes the paper self-contained: scripts/M3_SECTION8_BRACKET.R reproduces every quantity in the manuscript's Section 8 from these files alone, with an explicit PASS/FAIL line per claim (reference run: 12/12), and scripts/REPLICATE_ALL_v5_2.R runs the complete battery in one command. Contents: household and self-help-group data from the first author's community-based health insurance fieldwork in India and Nepal (EU FP7 HEALTH-F2-2009-223518 and related studies); the construction-sensitivity replication bounding the sustainability threshold from above (S* <= 0.056 episode-burden construction; <= 0.053 borrowing construction); the two recovered actuarial source instruments that set the floors, the BAIF Pratapgarh administration calculator (2010; break-even membership n* = 271.93 households from its own cells) and the GIZ Bangladesh floater premium calculator (2011; recorded 7.99% loading reproduced by lambda(n) = z.d/(pi.sqrt(n))); cell-level provenance documentation; codebook; file manifest.
