A market has N=28 firms each with identical costs C(q)=1q²+40. Demand is Q_D=800-4p.

What will be the short-run equilibrium price?

Expert Solution

The number of forms in the industry is 28, the record, it is a case of perfect competition. The forms will maximize profit at the point where MC is equal to Price.

C = q^2 + 40

Differentiating C wrt q, we get

MC = 2q

Given, demand cure, Q =.800 - 4P

The demand of whole industry would be equal to 28q.

Price, P = 2q = 2 × 22.22 = $ 44.44

Consider a market with n firms, where all firms produce identical commodities. The market demand curve is p = a − bq where a > 0 and b > 0, and where q = q1 + q2 + · · · + qn, with qi being the quantity produced by Firm i, i = 1, . . . n. Firm i’s profits are πi(q1, q2, . . . , qn) = pqi − cqi , where c is the per-unit...
