Because of the assumption of joint production, the supply responsiveness of the poultry sector depends on an aggregate poultry price, which is an average of the high- value and low-value poultry prices. Joint production links the high-and low-value supplies and thus affects the simultaneous price determination in both markets. For example, an increase in the high-value poultry price will encourage more high-poultry products to be produced. However, to produce more high-value poultry also entails the production of more low-value poultry products. .
