In Simple Words
Imagine two store owners from the same hometown exchanging goods in a crowded market. The seller offers a discount simply because they share common heritage and culture, similar to giving a friends-and-family discount, rather than because they expect lower default risk or higher financial honesty.
Audited buyer-seller matches in Chennai
- Different ethnic groups
- Reference price
- Same ethnic group
- Lower negotiated price
Randomly matched same-group buyers received price discounts but no clear reduction in customized-order advance payments. Preference-based discrimination is the authors’ interpretation, not a separately randomized mechanism. Randomized audit matches. No clear reduction in advance payments; preference rather than trust is an interpretation.
See source →Research question
Weak legal and contractual governance in developing markets causes traders to rely on ethnic identity when structuring business transactions. Market participants frequently misattribute price reductions between co-ethnics to enhanced trust rather than personal affinity.
Participants
107 pen and stationery wholesale stores located in Chennai, India.
Study Design
Randomized audit experiment matching buyers and sellers across Tamil, Marwari, and Andhra ethnic groups.
Results
Buyers received a discounted price when randomly matched with a wholesaler from their own ethnic group, but sellers did not reduce advance payment demands for co-ethnics.
Takeaway
Decouple price concessions from credit risk assessments during transaction auditing to isolate preference-driven discounts from risk-mitigating financial terms.
