Why can farmers not quickly switch to another product when crop prices fall?

Farmers cannot quickly switch to another product when crop prices fall primarily because agricultural production is tied to a fixed production cycle. Once a crop is planted, the farmer is committed to that production plan until the cycle is complete, as there is very little that can be done to increase or decrease output in response to immediate market fluctuations.1

Furthermore, farmers generally must produce based on expectations of future demand. If these expectations prove incorrect, the resulting surplus or shortage cannot be corrected until the beginning of the next production cycle. As long as the market price covers current operating costs, such as the expense of harvesting, it remains economically rational for farmers to carry through with their existing plans even if prices fall to low levels.1

Because no single producer can influence market prices by withholding their product, and because the quantity of a commodity supplied does not adjust proportionally to price declines, the farm manager faces significant limitations in responding to market volatility.2
