This paper shows that suppliers can be separated into different categories under an oligopoly market and that policy effects on each group of suppliers can be different. Simulation results from an oligopoly model with domestic and foreign suppliers suggest that the 13% increases in the raw milk price has no significant effects on the price and consumption of infant formula regardless of demand elasticities. Price increse in the raw milk, however, causes a large decrease in the consumption of domestic infant formula.
