2.3 Consider a competitive market with the following equations of demand (D) and supply (3). Do! P = 60 %0d Sn: P =20 + V205 If this market has 1,000 consumers with identical individual demand cunre, what is the equation of the demand curve of each of these consumers? [Hint: Denote the quantity demanded by each consumer by qd.] Derive the equilibrium price (Po) and quantity (Go) in this market. If the demand equation becomes D1: P = 80 '/2Qd while the supply remains as $0, propose and briey explain two possible reasons that can lead to such a change. Derive the equilibrium price (P1) and quantity (Q1). If the supply equation becomes 82: P = 40 + 1x'zQs while the demand remains to be Do, propose and briey explain two possible reasons that can lead to such a change. Derive the equilibrium price (P2) and quantity (Q2)
