Write a program that will continually prompt a user to enter a negative number until a negative number is inputted. If a negative number is enter, output "Thank you for inputting the negative number: " followed by the number if a non negative number is inputted, continually prompt for a negative number until one is given. Sample A: Enter a negative number: -4 Thank you for inputting the negative number: -4 Sample B: Enter a negative number: 10 Enter a negative number: 2 Enter a negative number: -1 Thank you for inputting the negative number: -1

Question 23 Give an example of two functions, $f$ and $g$, such that... $\cdot \lim_{x \to 1} f(x)$ does not exist, $\cdot \lim_{x \to 1} g(x)$ does not exist, and $\cdot \lim_{x \to 1} (f(x)g(x)) = 0$ (Hint: This is easiest to do with piecewise functions). Explain why your example does not contradict the limit law for multiplication.

1. (True or False) Monopolists are neither productively efficient nor allocative efficient, and perfect competition is both productively efficient and allocatively efficient. However, Pareto optimal requires it is impossible to make one person better off without making at least one other worse off. 2. Firm 1 and Firm 2 are automobile producers. Each has the option of producing either a big car or a small car. The payoffs to each of the four possible combinations of choices are as given in the payoff matrix below. Each firm must make its choice without knowing what the other has chosen. FIRM2 FIRM 1 Big car Small car Big Car (400,400) (600, 900) Small car (1200, 800) (500,500) Does either firm have a dominant strategy? Identify the Nash equilibrium. 3. A monopolist has a demand curve given by P = 100 - Q and a total cost curve given by TC= 160 + Q2 Find the monopolist's profit-maximizing quantity and price. How much economic profit will the monopolist earn? Now suppose the monopolist has a higher fixed cost, specifically a total cost curve given by 500 + Q2 Find the monopolist's profit-maximizing quantity and price. How much economic profit does the monopolist earn? What is the welfare loss of monopoly power (i.e. the deadweight loss) in a. and b above. 4. Consider a duopolistic market where demand is given by P = 36 - 3Q, where Q = Q1 + Q2. For each duopolist, the constant per unit marginal cost is $18/unit and fixed costs are zero. Assume first that the duopolists hold Cournot conjectures when they make their choices. Find the Cournot equilibrium price, quantity, and profits. Now find the equilibrium price, quantity, and profits assuming the duopolistic competition as Bertrand. Find the equilibrium um price, quantity, and profit for each firm, assuming the firms act as a Stackelberg leader and follower, with Firm 1 as the leader.
