    increase in demand
  3. (Advanced analysis) Answer the question on the basis of the following information. The demand for commodity X is represented by the equation P=10-0.2Q and supply by the equation P=2+0.2Q. Refer to the above information. The equilibruim quantity is:
    20
  4. Suppose that corn prices rise significantly. If farmers expect the price of corn to continue rising relative to other crops, then we would expect:
    the supply to increase as farmers plant more corn

  7. In the following question you are asked to determine, other things equal, the effects of a given change in a determinant of demand or supply for product X upon (1) the demand (D) for, or supply (S) of,, X, (2) the equilibrium price (P) of X and (3) the equilibrium quantity (Q) of X.
    increase D, increase P and increase Q
  8. Refer to the above diagram A government-set price floor is best illustrated by:
    price of C
  9. When the price of a product increases, a consumer is able to buy less of it with a given money income. This describes the

    opportunity costs
  14. (Consider This) In response to the terrorist attacks of September 11, 2001, the government decided to allocate more resources toward defense goods. The government's decision reflects their assessment that:
    the marginal benefits of additional defense goods outweighed the marginal cost
  15. Answer the question on the basis of the data given in the following production possibilities table: For these data the law of increasing opportunity costs is reflected in the fact that:
    larger and larger amounts of capital goods must be sacrificed to get additional units of consumer goods.
  16. The production possibilities curve has:
    a negative slope that increases as we move along it from left to right
  17. Answer the question on the basis of the following five data sets wherein it is assumed that the variable shown on the left is the independent variable and the one on the right is the dependent variable. Assume in graphing these data that the independent cariable is shown on the horizontal axis and the dependent variable on the vertical axis. Q: Refer to the data sets, the vertical intercept is positive for:
    data sets 1 and 3 only

    all of the means identified in the other answers
  27. "Because the outputs of many industries are the inputs to other industries, the failure of any single industry to fulfill the output quantities specified in the central plan caused a chain-reaction of adverse repercussions on production." This quotation best identifies the:
    coordination problem under central planning
  28. Firms are motivated to minimize production costs because:
    competitive pressures in the market will drive out higher-cost producers.
