  • Section 1Multiple Choice QuestionsTotal Points 70 CHAPTER 8THE CLASSICAL LONG-RUN MODEL

    1. According to Keynesian economists,

    a. the economy will return quickly to full employment in most cases

    b. if output is below its potential, the economy will soon return to full employment

    c. production can be stuck below its full-employment level for extended periods of time

    d. the Great Depression proved that classical economics does a good job of explaining how the

    economy operates

    e. he economy will achieve full employment in the short run but, in the long run, GDP will

    fluctuate

    2. Say's Law

    a. is valid only in a simple economy without financial markets

    b. led economists during the 1920s to encourage the government to adopt flawed economic

    policies that led to the Great Depression

    c. assures us that in the aggregate, firms are able to sell their output so that full employment

    can be sustained

    d. tells us that in the long run, markets clear

    e. tell us that firms must carefully monitor consumer spending and saving in order not to

    produce more than consumers are willing to purchase

    a. markets are perfectly competitive in the short run

    b. markets clear in the long run

    c. markets clear in the short run

    d. markets are perfectly competitive in the long run

    e. all variables are expressed in nominal terms

    4. The labor supply curve shows

    a. how much output a firm will supply with a given amount of labor

  • Section 2Essays and AnalysisTotal Points 30

    1. Classical and Keynesian economists differ diametrically in their views regarding the impacts of

    government spending. Explain the impacts of a $700 billion increase in a government spending program on output (income), comparing and contrasting the multiplier effect in the Keynesian theory and the crowding out effect of the Classical approach. Use both words and graphs of both models in your analysis (10 pts).
