Sugar is produced in a perfectly competitive market using inputs from perfectly competitive factor markets. Frank Sugar Co. is a representative firm in the sugar market.
Assume the demand for sugar increases and sugar is produced in a constant-cost industry.
On your graph in part (a), show the short-run effect of the increased demand for sugar on the market price, labeled P2, and the quantity sold by Frank Sugar Co., labeled QN.
On your market graph from part (a), show a rightward shift in the market demand curve with a higher market price, labeled P2, and show an upward shift in the firm's demand curve with a greater quantity sold by Frank Sugar Co., labeled QN.
