The growth of concentration rates in many sectors of the economy, always worried economists and served as the foundation for studies about the issue of market power. In this sense, the Brazilian dairy industry has not passed the margin of this concern. The process of restructuring by which the industry has, since 1990s, resulted in a wave of mergers and acquisitions that reached all the productive chain and resulted in increased market concentration. At the same time, there was a significant increase in production, productivity and the average volume produced per establishment, while the number of farmers and the prices paid for raw milk dropped considerably over much of the period. In this context, early indications of market power were investigated by the Parliamentary Committees of Inquiry and remains the focus of attention in economic literature to this day. Therefore, this study aimed to identify the degree of market power in the two main links in the chain, ie between milk producers and dairy products and dairy products, and among retailers. To achieve the objective the relevant markets were defined for each link of the chain as the market for raw materials, represented by the sale of raw milk, in natura, between farmers and dairy products, limited middle region boundaries, while the market was delimited to the wholesale marketing of UHT milk and dairy products among retailers, limited to a single market formed by the states of RS, PR, SP, MG and GO. The results suggested that the conduct of the dairy industry, in the market of raw material, is much closer to a dynamic market with perfect competition, the exception was messoregião Vale do Paraíba Paulista where oligopsony power was found, however, the distortions caused by market power were small. With regard to the wholesale market since the market is represented by a bilateral oligopoly, the results indicated that the dairy industry is a price taker but retailers carry oligopsony power. The estimate of conduct parameter was 0.638, demonstrating that the market departs considerably from a perfectly competitive market and pointing to the market power that retailers have upon the dairy industry and indirectly, over the entire dairy production chain.
