ABSTRACT: The primary purpose of this study is to evaluate the role of the US in the worldwide production and trade of pistachios, identify and estimate the major factors affecting export demand for US pistachios in 21 major markets, accounting for 78 percent of total US pistachio exports. The study estimated the impacts of US pistachio own price, cross price, importing markets’ GDP, real exchange rates and effect of food safety shocks. A panel data analysis was conducted using data from 1989 to 2009. A Houseman test indicated that the random effects estimator was the chosen estimator.
