Polish economic data are assembled in order to assess the impact on the agricultural sector of the recent reforms. Evidence of recovery in this sector is slight, but the decline seems to have halted. Policy issues for agricultural reform are discussed, emphasizing regulation of monopolistic input and processing sectors. The evidence for the existence and nature of these monopolies is reviewed and the goals of the chief regulatory body in Poland, the Antimonopoly Office, are summarized. A selection of recent models in industrial organization, dealing with entry, horizontal mergers and vertical control are used to provide a basis for assessing the direction of Polish regulatory policy.
