N. Suzuki et al., EVALUATING GENERIC MILK PROMOTION EFFECTIVENESS WITH AN IMPERFECT COMPETITION MODEL, American journal of agricultural economics, 76(2), 1994, pp. 296-302
A framework is proposed for incorporating the degree of market competi
tion in evaluating milk promotion effectiveness. The imperfect competi
tion model allows simultaneity in price and quantity with an endogenou
s fluid milk premium. The model's usefulness is demonstrated with Japa
nese generic milk promotion data. Results show a conventional exogenou
s-price or exogenous-premium model will underestimate returns to milk
promotion.
