بررسی ساختار انحصار در بازار داخلی پسته ایران و تاثیر آن بر گروههای مختلف (بویژه تولید کنندگان)

Efficacy of encouraging and punishing policies of government in different markets is related to market power. Study of market behavior is also important for efficient structuring of tools such as commodity exchanges and cooperatives. In this study, market power structure of pistachio domestic market in Iran was investigated. Sample was 343 pistachio producers and 252 pistachio traders from 5 provinces; Kerman, Fars, Khorasan, Tehran and Yazd. Two methods of Structure- Conduct - Perfom1ance Paradigm (SCPP) and New Empirical Industrial Organization (NEIO) were used for measuring market power. Results indicated that competitive market is proved in level of local buyers according to structure, conduct and perfonnancc investigations. But, for pistachio exporters, although market structure is competitive, conduct and performance show oligopsony behavior. Results, also, showed producers' welfare is reduced and welfare of pistachio traders is enhanced because of oligopsony behavior. More investigation revealed that the causes of market power in pistachio market are financial problems, distrust conditions, psychological atmosphere and wide range of pistachio qualities. Finally, for pushing pistachio market toward competitive conditions, some suggestions were made.
