In this research, we aimed to determine the correlations between pistachio production and producer income in Turkey. All producers make a decision looking at price levels 2.7 years ago. Pistachio production was effected from the lagged value of average price. We used the Koyck model at the calculation of lagged value. At this model, pistachio production (dependent) and pistachio prices (independent) were taken into consideration as variables between 1980 and 2019
