Game Show Host Excellent work. You just earned $100! And here's question number seven: In the long run, a firm under the monopolistic competition market structure: Can earn positive economic profits. Will earn zero (normal) profits. Submit
1. A risk-neutral monopolist is confronted with the choice between two technologies. If the first technology is adopted, total cost of producing \(y\) units of output is \(2y\). If the second (risky) technology is adopted, total cost of production is either \(y\) or \(3y\) with equal probability. The demand curve for the monopolist's product is \(P = 5 - y\). The monopolist will know the actual production cost before choosing his price and output. Which technology will be chosen? Give an economic explanation for your answer.
