Dr. Haoyu Liu's recent paper "Incentives for disclosing the store brand supplier" won the Best Paper Award of Omega (The International Journal of Management Science).

The paper is a joint work by researchers from Mainland China, Taiwan, Hong Kong, and Macau. The authors study whether the store brand supplier information should be disclosed to the public. They show that both the retailer and the manufacturer may adopt a non-disclosure strategy when the quality perception difference is sufficiently small, and in such an equilibrium, mandatory information disclosure is detrimental to consumer welfare.
