Practice Questions 3-
I. True/False and explain:
1. The classical model takes a short-run view of the economy, while the Keynesian model takes a more long-run view.
2. The classical model focuses primarily on nominal values.
3. The key assumption of the classical model is that the labor market and the loanable funds market clears while other markets do not necessarily clear.
4. According to the classical view, the economy needs the government's help in achieving full employment.
5. The aggregate production function tells us how much output can be produced with different combinations of capital, land and labor.
6. An aggregate production function as studied in the classical model illustrates the law of diminishing returns to labor.
7. Say's law assures us that total spending is always just right to purchase the economy's total output.
8. The existence of excess supplies or excess demands in some markets is inconsistent with Say's law.
9. Investment spending and government purchases play the role of "injections" in the classical model.
10. In the classical model, leakages from the income-expenditure stream include taxes, saving, and export.
11. In the classical model, an increase in government spending-with no other change-will shift the total demand for funds curve rightward.
12. The key conclusions of the classical model do not hold if the government is running a budget surplus rather than a budget deficit.
13. In the classical model, an increase in government purchases causes household saving to increase, and household consumption spending to decrease.
14. In the classical model, an increase in government purchases obtained by reducing transfer payments will not change the interest rate and furthermore, will not provide any incentive for households to save more.
15. Consider a ray from the origin that goes through a particular point on the aggregate production function. We know that the slope of this ray is a measure of the labor productivity.
16. "Net taxes" are equal to the government's total tax revenue minus government transfer payments.
17. An increase in the labor supply curve or an increase in the labor demand curve will have the same effect on economic growth and the wage rate.
18. When output grows more slowly than the population, real GDP per capita-which we call the average standard of living-will fall.
19. Increases in employment, with a constant capital stock, tends to raise productivity.
20. An investment tax credit promotes economic growth primarily by inducing firms to hire more workers, thus moving the economy along its aggregate production function.
21. A decrease in the budget deficit promotes economic growth primarily by lowering interest rates, which increases investment and speeds growth in the capital stock.
22. Less developed countries with very low growth rates typically suffer from a poor infrastructure and very low population growth rates.
