Buyers' response to third‐party quality certification: Theory and evidence from Ethiopian wheat traders

American Journal of Agricultural Economics, EarlyView.
Abstract When quality attributes of a product are not directly observable, third‐party certification (TPC) enables buyers to distinguish between quality levels and reward sellers accordingly. We study the adoption of TPC by traders in smallholder‐based agricultural value chains in low‐income countries, where traders aggregate products from many small ...
