3. Why did the Bush administration rely heavily on air power and advanced technology?
They used air superiority, precision‑guided munitions, surveillance, and electronic warfare to degrade Iraqi command, logistics, and air defenses before a ground assault. This approach reduced U.S. casualties, shortened the campaign, and leveraged technological advantages to achieve rapid operational effects while avoiding protracted ground combat that characterized Vietnam.

Do monopolistically competitive (MOCO) firms typically earn positive economic profit in the long run? Explain why or why not.
In the long run, firms in monopolistic competition normally earn zero economic profit (normal profit), not positive economic profit.
Reasoning:
Short run: Because products are differentiated and each firm faces a downward‑sloping demand curve, a firm can set price above marginal cost and may earn positive economic profit.
Free entry and exit: Monopolistically competitive markets have low barriers to entry, so positive profits attract new firms producing similar (differentiated) products.
Demand shifts: Entry reduces the demand faced by each incumbent firm (the firm’s demand curve shifts left and becomes more elastic), eroding profits.
Long‑run equilibrium: Entry continues until economic profits are driven to zero—price equals average total cost at the firm’s profit‑maximizing output (P = ATC), although price still exceeds marginal cost (P > MC).
Implications: Firms earn zero economic profit in the long run, may earn positive accounting profit, and operate with excess capacity because they produce where demand is tangent to ATC rather than at the ATC minimum.
