Earlier quoted context omitted.
More typically, farmers produce 10 units, sell 3, and buy another 10 later in the year. Hence any rise in price is a net loss for them.
How did that ever work?
"subsistence farmers are net consumers of their staple crop. In order to survive, the poor diversify across a variety of agricultural products"
I don't understand the downvotes for the parent. They are growing other products, or have cash from other activities, and use this to buy the staple they can't grow. If price of staple rises and price of other products and services does not, they can't afford to do this. The beneficiaries are large industrial farmers of the staple. Did I miss something?
