This paper aimed to study the spatial price integration of Iran's pistachio prices with USA prices as a major rival country of Iran in world market. Time series data on domestic and export prices were collected for the time periods 1982-2003 and 1991-2004 and analyzed using Co-integration analysis and Dickey-Fuller test. The price series used for comparison were Iran's producer and export prices, Iran and USA export prices and Iran and USA producer prices. Our results revealed that none of the price series were co-integrated. This shows that the so-called low of one price could not be held, and so the prices were not moving together in a long run.
