Investigation of income fluctuations of Iranian pistachio producers

In this study income fluctuations of Iranian pistachio producers and its causes were investigated. The results show that this instability is high and risky. Thus farmers cannot forecast and eliminate income variability. The results, also, show that both pistachio price and yield variations have impacts on income fluctuations. In other words, if the income variability should be approached zero, both price and yield volatility should be reduced. Thus a portfolio of crop insurance and exchange market for pistachio is necessary. But the success of these tools in Iran should be investigated more.
