In this paper, we decompose multiplicatively indices of value instability of agricultural exportable and importable products into price instability, quantity instability, and interactive instability. Indices of Iranʹs agricultural trade instability corresponds to 26 exportable and 22 importable. The period of analysis runs from 1981-1999.
The main results of this paper are:
-Iranʹs agricultural exports and imports both vary in degree of instability.
-In the cases of several exportable and importable , quantity
instability has been the determining factor of value instability
-On the average, exports have been subject to relatively higher
price and value instability than imports, but imports have been
subject to higher quantity instability than exports.
The study also presented a number of recommendations to reduce instabilities and to increase competitiveness in Iran.
