Economic Returns to Social Capital in the Urban Informal Sector in Developing Countries: Micro Evidence from Small Textile Producers in Bolivia
Bibliographic record
Abstract
The paper uses micro-level data obtained from surveying informal and formal small textile producers in Bolivia to estimate the economic returns to social capital. Social capital is defined as being linked to other individuals. The paper studies forms of social links that vary with respect to their inclusiveness and their ability to enforce cooperation. The paper shows, first, that social capital has an economic return for informal firms but not for formal ones. Informal firms operate without the shadow of courts in an environment that is characterized by a lack of anonymous trust which makes self-enforcing social links valuable. Second, more inclusive social capital generates a higher return as long as the self-enforcement constraint is met. The evidence supports the hypothesis that the “strength of weak ties”- argument advanced by scholars such as Granovetter, Putnam, and Fukuyama has to be complemented by the game-theoretic condition requiring exchange among linked players to be (self)-enforceable.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
