The granger-causality relationship between energy productivity and added-value of Iran’s agricultural sector

الملخص EN

Oil products and electricity are the main sources of energy for the agricultural sector of Iran.

In the period 1989-2012, the use of this energy carrier has increased at an average rate of 35.6% , whereas the average annual growth rate of the value-added of the agricultural sector has been 3.31% over the same period and the productivity trend of energy carriers has always been on a fall so that their average annual growth rate in the agricultural sector of Iran has been -14.33% .

The present study aimed to explore the effectiveness of energy productivity on the added-value of the agricultural sector.

The results showed that the two variables had no causal relationship.

It can thus be said that other factors are influential on the added-value of the agricultural sector and that for the productivity of energy carriers to be influential on the agricultural sector, it is necessary to examine a combination of pricing and non-pricing policies.
