Equilibrium occurs at Y = C + I + G = 900.

14. CHAPTER 9 The Government and Fiscal Policy © 2009 Pearson Education, Inc. Publishing as Prentice Hall Principles of Macroeconomics 9e by Case, Fair and Oster 14 of 39 Government in the Economy The Determination of Equilibrium Output (Income) The Saving/Investment Approach to Equilibrium saving/investment approach to equilibrium: S + T = I + G To derive this, we know that in equilibrium, aggregate output (income) (Y) equals planned aggregate expenditure (AE). By definition, AE equals C + I + G; and by definition, Y equals C + S + T. Therefore, at equilibrium C + S + T = C + I + G Subtracting C from both sides leaves: S + T = I + G

In this section, we will review three multipliers: Government spending multiplier Tax multiplier Balanced-budget multiplier

As Y rises in response, additional consumption is generated. Overall, the equilibrium level of Y increases by 200, from 900 to 1,100.

The balanced-budget multiplier is equal to 1: The change in Y resulting from the change in G and the equal change in T are exactly the same size as the initial change in G or T.

Publishing as Prentice Hall Principles of Macroeconomics 9e by Case, Fair and Oster 23 of 39 The Federal Budget federal budget The budget of the federal government. The “budget” is really three different budgets. First, it is a political document that dispenses favors to certain groups or regions and places burdens on others. Second, it is a reflection of goals the government wants to achieve. Third, the budget may be an embodiment of some beliefs about how (if at all) the government should manage the macroeconomy.

Publishing as Prentice Hall Principles of Macroeconomics 9e by Case, Fair and Oster 31 of 39 The Economy’s Influence on the Government Budget Tax Revenues Depend on the State of the Economy Tax revenue, on the other hand, depends on taxable income, and income depends on the state of the economy, which the government does not completely control. Some Government Expenditures Depend on the State of the Economy Transfer payments tend to go down automatically during an expansion. Inflation often picks up when the economy is expanding. This can lead the government to spend more than it had planned to spend. Any change in the interest rate changes government interest payments.
