This study identifys the main factors influencing U.S. pistachio export demand in North America-i.e., to Canada and Mexico. A double-log econometric model is estimated using data for 1989-2009. The main findings indicate that Canadian GDP, U.S. walnut export prices, and food safety concerns explain the majorityof the pistachio import demand variation in Canada, wheras Iranian pistachio export prices, the real exchange rate between the Mexican peso and the U.S. dollar, and U.S. pecan export prices explain the majority of the Mexican pistachio import demand variation. The paper also investigates the impact of food safety issue om export demand. In order to maintain its export market, the U.S. has to find solutions to current food safety problems.
