Also, due to the spillover effects in the market of alternative products, the retail price of alternative products was also included in the models. To investigate price transmission patterns, the error correction approach with structural failure was used. Results and Discussion The results showed that in the short term for tiny pea and large lentil the price transmission is asymmetric and for large pea and tiny lentil is symmetric. In the long term, price transmission is asymmetric for all products, which seems to be due to the continuation of negative effects of economic sanctions and high
