In Simple Words
When a city has no working court system to enforce contracts, merchants cannot rely on legal contracts to get paid back. Instead, they rely on reputation and common background, assuming certain cultural communities are reliable business partners to reduce their risk of getting cheated.
Audited buyer-seller matches in Chennai
- Different ethnic groups
- Reference price
- Same ethnic group
- Lower negotiated price
The card’s general claim that ethnic affiliation shapes transaction pricing is supported by same-group discounts. The study does not test weak institutions against strong institutions or prove trust-based substitution. Randomized audit matches. This does not establish institutional substitution or greater trust; no smaller advance payments detected.
See source →Research question
Low- and middle-income markets frequently lack formal legal mechanisms and court infrastructure to enforce B2B debt repayment or sales contracts. Market participants use informal social traits and ethnic stereotypes as proxies to manage default risk and evaluate creditworthiness.
Participants
Small and Medium Enterprises (SMEs) across 107 wholesale stationery shops in Chennai, India.
Study Design
Randomized audit trial investigating how ethnic identities act as informal proxies for governance in high-risk business deals.
Results
In environments where formal contract enforcement is missing, traders systematically utilize ethnic group affiliation (e.g., Marwari, Tamil, Andhra) to structure pricing and risk terms.
Takeaway
Establish formal collateralized credit terms or escrow services to replace informal identity-based stereotyping in contract governance.
