An economic analysis of the demand for fresh cassava and cassava products in the Philippines
1985
Binongo, M.S.G.
The result of the food demand analysis show that cassava root consumed as food is an inferior good. The income elasticity estimate is -0.82. Rice and cassava roots are found to be substitute goods as indicated by the positive cross-price elasticity coefficient. The elasticity coefficient of cassava use with respect to the price of rice is 1.18. The result of the seasonal price variation analysis also show that rice and cassava are substitutes. The inclusion of dried cassava in mixed feeds is only possible if the price of cassava is very much lower relative to the price of corn that has been the case in the past. Cassava starch consumption has increased faster than corn starch consumption. A fall in the price of cassava relative to corn increases the share of cassava starch to total starch supply. cassava starch production is also very responsive to cassava root price decline as shown by the value of the elasticity estimate (-1.77) for cassava root price and starch prduction
