1. Suppose that a small, tropical country produces mangoes for domestic consumption and possibly for export. The national demand and supply curves for mangoes in this country are given by the following: P = 50 - M P = 25 + M (national demand) (national supply) where P denotes the relative price of mangoes and M denotes the quantity of mangoes (in metric tons). (a) Illustrate these relationships geometrically. What is the autarky price and quantity (b) exchanged? (c) Suppose that the world price of mangoes is 45. Will this small country export mangoes? If so, how many tons?
(a) Determine the equilibrium price and quantity.(b) Sketch the demand and supply functions on the same graph. Label theaxes and the intercepts clearly.
2. Reciprocal Dumping with transport costs. Consider two countries, i = {Spain, France}, each having the following inverse demand function: P = 20 – 2(qi+qi) where P is the price in Spain, qi is the quantity sold by the Spanish firm in Spain, and q is the quantity sold by the French firm in Spain. By analogy, the inverse demand function in France is: P 3D 20 — 2(ф2 + q2) where P* is the price in France, q2 is the quantity sold by the Spanish firm in France, and q5 is the quantity sold by the French firm in France. In each country there is only one firm. The cost function of the Spanish firm is: TC = 2(q1 + q2) %3D The cost function of the French firm is: TC* 2(qi + 2) To transport one unit from one country to the other, there is a transport cost t per unit. (There is no transport cost within countries.) 1
A1-1. Imagine that a market for a good is characterized by the following supply and demand equations: QS = –35 + 35P QD =100 – 10P where QS and QD are quantities in units and P is the price per unit. (a) Graph the supply and demand curves with quantity on the horizontal and price on the vertical axis. Be sure to calculate the P and Q intercepts for demand and the P intercept for supply. Calculate and illustrate the equilibrium price and quantity. [Hint: Show your work.] (b) Calculate both the demand and supply elasticity around the equilibrium point. [Hint: you can use either the point method or the average arc (midpoint) method.] (c) If a regulator imposes a quantity restriction by granting quotas for 60 units of output to existing producers, what is the new price and quantity traded? Does this policy create deadweight loss (DWL) in the market? Briefly explain and identify any DWL in your diagram. (d) What is the value of a unit of quota? Illustrate in your diagram.…

Consider the supply and demand curves for taxi rides in the attached graph. Even though the vertical intercept of the supply curve is not labeled, you can infer that it is equal to _______since the supply curve is a straight line and two points on the curve are labeled. (Answer with two digits after the decimal, e.g-, '0.75")
Home's Domestic Demand and supply curves for shoes are D = 500-10P and S = 300+20P. Foreign's domestic demand and supply curves for the same type of shoes are D = 1000-10P and S = 200 + 40P. (a) Find the autarky price and quantity for each country. If the countries trade, which country will export shoes? (b) Derive algebraically the import demand and export supply functions. Find the price and volume of trade with free trade.
5) The following equations represent the demand and supply curves in the competitive U.S. beef market: ?? = 92.82 − 12.75? - 8.25 ?? = 56? − 99.68 where quantities are measured in billions of pounds and price is measured in dollars per pound. C) What is the quantity demanded at a price of 2.8? What is the quantity supplied? Is the market experiencing a surplus or shortage of beef, and how big is that surplus/shortage?
