PART TWO: CLASSICAL ECONOMICS AND THE KEYNESIAN
REVOLUTION
CHAPTER 3: CLASSICAL MACROECONOMICS (I): OUTPUT
AND EMPLOYMENT
Additional Questions
Problems and/or Essay Questions:
1. Briefly define an endogenous variable and an exogenous variable. What variables are
endogenous in the classical model? What variables are exogenous.
2. Explain how an increase in technology, which increases the productivity of labor, will
affect the labor market, the production function, and aggregate output. Provide graphs to
illustrate.
3. What are the two key features of perfectly competitive markets in the Classical Model?
4. Explain how an increase in the public’s taste towards less leisure would affect the labor
market, the production function, and aggregate output. Provide graphs to illustrate.
5. Explain why the labor supply curve is positively sloped. Explain why labor demand is
downward sloping.
6. Using a graph of the classical labor market, illustrate the effects of a real wage existing in
the market that is lower than the equilibrium real wage. What will eventually happen in this
labor market if it is perfectly competitive?
7. What two principles of mercantilism did the classicists attack?
8. In the classical model, what is the impact of changes in the demand for goods and services
on aggregate output? Do they affect any real variables?
9. What is Real Business Cycle Theory? What drives business cycles in this model? Where do
10. Is there a positive or negative relationship between real wages and output in the classical
model? Explain.
11. Is it possible to have a production function that exhibits both a diminishing marginal
product of labor and constant returns to scale? Explain.
12. Suppose that the government imposes a tax on firms for money wages they pay. How
would this change the classical aggregate supply curve? Why?
Additional Problems and/or Essay Questions:
13. Consider an economy where the marginal product of labor is characterized by the following
equation:
14. A well known aspect of the classical model is Say’s Law, which states that supply creates
its own demand. In what sense does Say’s law hold in the classical model?
15. Use the graph of the aggregate production function (Figure 3.1) to explain the concept of
the marginal productivity of labor. Draw a graph of the marginal productivity of labor
schedule, with the level of employment on the horizontal axis. Explain the properties of this
schedule.
16. Suppose that you observe a fall in real wages at the same time that output is rising. How
would you explain this within the classical model of aggregate supply?
17. What factors change aggregate supply in the classical system? How do these factors affect
aggregate output? What factors change aggregate demand in the classical system? How do
these factors affect aggregate output?
18. How would you define “technology”. In the production function Y=F(K,N), where is
technology? Explain.
