Question 2: Suppose Qd= 100- 10P Qs = 10P a. Draw a graph using the supply and demand equation assuming no trade. Calculateequilibrium P, Q, consumer, producer and total surplus.   b. Draw another graph assuming that trade is allowed. Calculate quantity domesticallyconsumed, domestically produced, imports, consumer surplus, producer surplus assumingworld price =$3.   c. What happens to consumer surplus and producer surplus after trade? Does total surplusincrease or decrease after trade? Show your calculations.

Problem 1 Refreshing Refreshing Trade Basics - Prices Consider the market for computers in two countries, Uruguay and Indonesia. Let's assume both have perfectly competitive domestic computer markets. In autarky (no trade), the equilibrium price of computers in Uruguay is $500, and 10,000 computers are sold. In Indonesia (under autarky), the equilibrium price of computers is $400 and 8,000 computers are sold. (a) Draw supply and demand (partial equilibrium) graphs for each of these two countries indicating how many computers are sold and at what price when neither country trades (b) Now Uruguay and Indonesia open themselves up to global trade of com- puters. Let's assume the global price of computers is $450. Describe qual- itatively what happens to the price consumers pay for computers in each of these two countries (relative to the original autarky situation) as well as how much domestic producers sell now relative to the no trade world. Also state whether each country is an importer…

3. A fruit is traded in a competitive world market, and the world price is $10 per pound. The consumer quantity in this price is 100 million tonnes. One year later, overall fruit prices increase to $15 and total consumer level fall to 90 million tonnes. Under this circumstance, what is the price elasticity of demand fruit?

Question 2 A recent hot issue in Ghana is energy. Suppose the demand for energy is described by Q-50-0.5P and the supply of energy by Q-P-10. a. Graph the supply and demand curves carefully. Determine the equilibrium price and quantity of energy. b. Some lawmakers decide that the problem with Ghana is that the price of energy is too high. They propose a bill that would set a price limit of GHC30 per unit of energy. If enacted, what will be the effect of this law on the quantity of energy supplied and demanded? Is the market on equilibrium? Explain. If not, calculate the shortage/surplus that results. C. other lawmakers decide that energy prices are too low and are considering a tax on energy to encourage conservation. What will be the effect on equilibrium price and quantity of a GHC20 per unit tax on energy, if the tax is collected from suppliers? Show this on the original supply and demand diagram as well. d. Using the results from part (c) calculate the economic price incidence for…
