The seven crops represent 65% of the value of total crop production, and the six livestock products 90% of total livestock production. The corresponding data on domestic, external reference prices, and transportation, processing and handling margins have been collected and price gaps calculated for all 13 products. For the purpose of calculating the price gaps, five products - wheat, rice, maize, barley, and cotton - are treated as exportable products over the whole period. Five commodities - sunflower, potatoes, milk, poultry meat and eggs - are considered as the importable ones.
