SL 151 Bremmer II Name CM September 19 2006 1st In Class Exam Chapters 1 5 7 pp 527 530 Part I Multiple Choice 3 points each For each of the following questions indicate the best answer in the space provided Figure 1 1 Referring to the production possibilities curves shown in Figure 1 the most likely cause of a shift from C1 F1 to C2 F2 is A a reduction in the unemployment rate towards full employment B a decrease in the educational attainment of the population C only technological improvement in clothing production D depletion of natural resources used in the production of both goods E technological improvement in both cloth and food production 2 Referring to the production possibilities curve in Figure 1 the best explanation of a shift from C2 F2 to C3 F2 is A an increase in the natural resources used in the production of both goods B an increase in the labor supply used in the production of both goods C technological improvement in only clothing production D technological improvement in only food production E technological improvement in both food and clothing production 3 A B C D E Referring to the production possibilities curves shown in Figure 1 which of the following statements is are true Resources in this economy are not specialized and can be freely moved between food and cloth production As cloth production increases along a given production function its opportunity cost is constant As food production increases along a given production function its opportunity cost increases Figure 2 Both A and B Both A and C 4 Referring to the production possibilities curve shown in Figure 2 which of the following points represents a combination of goods that cannot be produced in the economy Point C Point A Point D Point F Point E A B C D E 5 Assuming an upward sloping supply curve and a downward sloping demand curve which of the following best explains an increase in market price and decrease in equilibrium quantity A An increase in supply D A simultaneous decrease in demand and increase in supply B A simultaneous decrease in both demand and supply E A decrease in demand C A simultaneous increase in both supply and demand 6 A B C D If the price elasticity of demand is equal to 1 75 then an increase in price will increase total revenue an increase in price will have no effect on total revenue an increase in price will decrease total revenue the absolute value of the percentage change in quantity demanded is less than the absolute value of the percentage change in price E Both A and D 7 A B C D Given a linear negatively sloped demand curve if price increases then you move up along the demand curve and the price elasticity of demand decreases you move up along the demand curve and the price elasticity of demand increases you move up along the demand curve and the price elasticity of demand remains constant the demand curve will shift to the left Page 1 E the demand curve will shift to the right Page 2 Figure 3 8 A B C D E 9 A B C D E Referring to the demand and supply curves shown in Figure 3 the demand curve will shift from D1 to D2 if income decreased and the good is normal the price of a complementary good fell the price of a substitute fell the price of the good fell consumers expect the future price of the good to fall Referring to the demand and supply curves shown in Figure 3 the supply curve will shift from S1 to S2 if the number of firms decreases the price of the good increases input prices increased the government imposed an excise tax on all producers None of the above 10 A surplus in the cardboard box market means that A the current price is below the equilibrium price B the price of a cardboard box will fall causing a downward movement along both the demand and supply curves towards equilibrium C the price of a cardboard box will increase causing an upward movement along both the demand and supply curves towards equilibrium D the price of a cardboard box will fall causing the demand curve for cardboard boxes to shift to the right and the supply curve of cardboard boxes to shift to the left E Both A and C 11 Assume the supply curve for a product is perfectly inelastic and the demand curve is linear and downward sloping If the government imposes a price ceiling which is 2 below the equilibrium price then A the resulting surplus will be greater the more elastic the demand curve B the resulting surplus will be greater the less elastic the demand curve C the resulting shortage will be greater the more elastic the demand curve D the resulting shortage will be greater the less elastic the demand curve E it won t be binding and price wouldn t change remaining at the initial equilibrium 12 A B C D Which of the following generalizations is correct The price elasticity of demand is greater for necessities than it is for luxuries The greater portion of one s budget that is spent on a good the demand for that good is less elastic The price elasticity of demand is greater the shorter the time period under consideration The larger the number of close substitutes available the greater will be the price elasticity of demand for the particular product E If a linear positively sloped supply curve cuts the vertical axis above the origin supply is inelastic at every price Figure 4 13 A product is an inferior good if A an increase in income causes the demand curve for the good to shift to the right B C D E 14 A B C D E its income elasticity of demand is negative its income elasticity of demand is positive its cross elasticity of demand is negative its cross elasticity of demand is positive Who gains from international trade Only the exporting nation Only the importing nation Both the importing and the exporting nations Neither the importing nor the exporting nations There are no gains from trade as it is impossible to consume a bundle of goods that lies above the PPC 15 Given the demand curve in Figure 4 between prices P1 and P2 you can correctly conclude that Page 3 A demand is unitary elastic D consumer purchases are relatively insensitive to price changes B demand is inelastic E demand is perfectly inelastic C demand is elastic Part II Short Answer Questions 55 points total For each of the following questions give a concise but complete answer When appropriate use math graphs or equations to help explain your answer Completely label all graphs If you require more space right on the back of each page indicating that you have done so 1 An economy with specialized resources produces two
