Discussion Question 10
(a) The inelastic demand of agricultural commodities causes revenue to decrease when prices decrease. After a good harvest, supply increases, which would cause prices to decrease, thus lowering farmers’ incomes.
(b) The incomes of farmers fall in relation to other sectors of the economy because regardless of the pricing, the demand for agricultural commodities does not increase significantly because they are a necessity to society.

Also, if consumers have an increase in income, they are not likely to buy more of a significant amount of agricultural commodities, but are likely to spend their money in other sectors such as luxury goods.
Problem 3
(a) Qc = 100,000 -100Pc + 2,000N + 50I + 30PF - 1,000PG + 3A + 40,000PI
Qc = 100,000 - 100Pc + 2,000(225) + 50(12,000) + 30(10,000) – 1,000(100) + 3(250,000) + 40,000(0)
QC = 1,900,000 – 100PC
(b) Qc = 1,900,000 – 100(10,000)
Qc = 900,000
