Question 1 There are 10,000 identical individuals in the market for commodity X, each with a demand function given by Qodx = 12 - 2Px, and 1000 identical producers of commodity X, each with a function given by Qsx = 20 Px. where Qox is an individual's quantity demanded, Qsx is a single producer's quantity supplied, and Px is the price of the commodity. (a) Find the market demand function (QDx) and the market supply function (QSx) for commodity X (b) Determine the market demand schedule and the market supply schedule of commodity X (for whole dollar prices) and from them find the equilibrium price and the equilibrium quantity. (c) Plot, on one set of axes, the market demand curve and the market supply curve for commodity X and show the equilibrium point (d) Obtain the equilibrium price and the equilibrium quantity mathematically. (e) Explain why the equilibrium condition is considered stable. (f) Determine the elasticity of demand for commodity X at the equilibrium point. Question 2 Suppose that from the condition of equilibrium in Question 1, there is an increase in consumers' incomes (ceteris paribus) so that a new market demand curve is given by QDx = 140,000 - 20,000Px. (a) Derive the new market demand schedule (b) Show the new market demand curve on the graph used in Question 1(c) (c) State the new equilibrium price and equilibrium quantity for commodity X (d) Determine the Income Elasticity at the original equilibrium price and at the new equilibrium price. (Assume that the increase in income is 106). (e) In the light of your answer to 2 (d), comment on the nature of commodity X.4. Vacancy costs and the labor market. Consider the search-theoretic model of the labor market of Diamond {1982), Mortensen (1982} and Pissarides (1985). a. The equilibrium tightness of the labor market, 6", solves the following equation -ny-w luWWW Plot the left and the right hand side of the above equation as functions of 9 and identify 6'. k=so b. Using the same yaph as before, identify the effect of an incraese in the vacancy cost it: on the equilibrium tightness of the labor market. Interpret your nding. c. The equilibrium unemployment, n", and the equilibrium vacancies, v", solve simultaneously the following system of equations Plot the solutions to these two equations in a graph that has it on the horizontal axis and v on the vertical axis (Le. plot the Beveridge curve and the market tightness curve]. Identify n\" and 11*. (1. Using the same graph as before, illustrate the eifect of an increase in the vacancy cost I: on the equilibrium unemployment and vacancies. Interpret your ndings. e. Should the government intervene to lower unemployment in response to an increase in k? 4. (30 points) Consider the following game. There are ten dollars to divide. Two players are each required to simultaneously name an integer between 0 and 10. The player who names the higher number gets to keep the money. If they name the same number, the money is equally shared between them. (a) Describe the set of players N, the set of strategies { Silien, and the payoff function QuitiEN. (b) Are there strategies that are strictly dominated? Demonstrate your reasoning. What are the resulting strategies after iterated elimination of strictly dominated strategies? (c) Find the best responses (correspondence) for each player. That is, find the strategies that maximize a player's payoff given what the other player does. (d) Find the Nash equilibria of the game. (e) Suppose now the game is changed. Whenever there is a tie, each player receives nothing. Answer the same questions in parts (b) and (c). Find the pure-strategy Nash equilibria of the game.vi payments accounts, still PLEsuit IsOnly foreign currency traded with the Canadian dollar. 7. For each of the following situations, outline the effect on the price of the Canadian dollar in terms of US dollars and draw a demand and supply graph that illustrates the changes that occur in the foreign exchange market for the Canadian dollar. . A contractionary monetary policy initiated by the Bank of Canada raises Canadian interest rates. b. Canada's real output rises at a time when real output in the United States is falling. c. Americans (but not Canadians) find Canada a more attractive place to make financial investments. d. Given Canada's aging population, more Canadian "snowbirds" travel to the United States each winter. e. Due to a credit crisis that affects US financial institutions more than it does Canadian ones, Canada's attractiveness as a destination for direct and portfolio investment increases. f. The Bank of Canada initiates an expansionary monetary policy that reduces Canadian interest rates
