A duopoly market may not necessarily decrease consumer cost price. In fact, duopolies tend to have higher prices compared to more competitive markets due to the limited number of firms controlling the market. The lack of competition can lead to higher prices and reduced consumer choice. However, in some cases, duopolies may lead to lower prices if the two firms engage in price competition to attract customers. Overall, the impact of a duopoly on consumer cost price can vary depending on the specific market conditions and the behavior of the firms involved.
