The disposable income (Yd) of households must end up as either consumption (C) or saving (S). Thus,
Y C Sd
Y T C S
Y C S T
Because disposable income is aggregate income (Y) minus net taxes (T), we can write another identity:
By adding T to both sides:
Planned aggregate expenditure (AE) is the sum of consumption spending by households (C), planned investment by business firms (I), and government purchases of goods and services (G).

budget deficit The difference between what a government spends and what it collects in taxes in a given period: G − T.
budget deficit ≡ G − T
To modify our aggregate consumption function to incorporate disposable income instead of before-tax income, instead of C = a + bY, we write
C = a + bYd
or
C = a + b(Y − T)
Our consumption function now has consumption depending on disposable income instead of before-tax income.

The Determination of Equilibrium Output (Income)

FIGURE 9.2 Finding Equilibrium Output/Income Graphically
Because G and I are both fixed at 100, the aggregate expenditure function is the new consumption function displaced upward by I + G = 200.
Equilibrium occurs at Y = C + I + G = 900.

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
The Saving/Investment Approach to Equilibrium

Increasing government spending by 50 shifts the AE function up by 50.
As Y rises in response, additional consumption is generated.
Overall, the equilibrium level of Y increases by 200, from 900 to 1,100.

The Tax Multiplier
Because the initial change in aggregate expenditure caused by a tax change of ∆T is (−∆T × MPC), we can solve for the tax multiplier by substitution:
Because a tax cut will cause an increase in consumption expenditures and output and a tax increase will cause a reduction in consumption expenditures and output, the tax multiplier is a negative multiplier:

balanced-budget multiplier The ratio of change in the equilibrium level of output to a change in government spending where the change in government spending is balanced by a change in taxes so as not to create any deficit. 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.

What happens when there is a simultaneous increase in government spending of $100 and a lump-sum tax of $100?
a. Equilibrium income would increase by $100, or the amount of increase in G.
b. Equilibrium income would decrease by $100, or the amount of increase in T.
c.Equilibrium income would decrease by $200, or double the amount of the increase in T.
d.Nothing happens. Equilibrium income remains the same because the amount of government spending (G) is compensated by the amount of taxation (T).

A Warning
Although we have added government, the story told about the multiplier is still incomplete and oversimplified.
We have been treating net taxes (T) as a lump-sum, fixed amount, whereas in practice, taxes depend on income.
Appendix B to this chapter shows that the size of the multiplier is reduced when we make the more realistic assumption that taxes depend on income.
We continue to add more realism and difficulty to our analysis in the chapters that follow.

federal budget The budget of the federal government.
The Federal Budget
Because fiscal policy is the manipulation of items in the federal budget, that budget is relevant to our study of macroeconomics.
An enormously complicated document up to thousands of pages each year, the federal budget lists in detail all the things the government plans to spend money on and all the sources of government revenues for the coming year.
It is the product of a complex interplay of social, political, and economic forces.

The U.S. Congress Fights about the Budget
In January 2013, Congress signed the American Tax Relief Act (ATRA), which retained many of the earlier Bush tax cuts, while modifying others. But the specter of automatic spending cuts remained.
In the spring of 2013, arguments about the shape of the 2014 budget were raging, as members of the House commented on a budget proposal of Paul Ryan, Republican Congressman from Wisconsin.
Representative Eddie Bernice Johnson of Texas, a Democrat, had this to say about Congressman Ryan’s bill: “This budget would not only jeopardize seniors, families and the most vulnerable in our society, it would also destroy jobs and put our nation’s economic recovery at risk.”
The Congress heard a different view from Andy Barr, a new Republican Congressman from Kentucky: “Families and small businesses should be able to keep more of their hard-earned income instead of having it wasted by Washington bureaucrats.”

The Debt Clock
Next time you are in New York City, wander by West 44th Street and the Avenue of the Americas.
Located on an outside wall is a U.S. Debt Clock, mounted by Seymour Durst, a N.Y. real estate developer.
Rather than showing us the passage of time, as would a conventional clock, this clock shows us the mounting of the U.S. debt.
Durst was an early worrier about the debt! Needless to say, it sped up during the Obama administration. See Figure 9.7.

Looking Ahead
We have now seen how households, firms, and the government interact in the goods market, how equilibrium output (income) is determined, and how the government uses fiscal policy to influence the economy.
In the following two chapters, we analyze the money market and monetary policy—the government’s other major tool for influencing the economy.

We can derive the multiplier algebraically using our hypothetical consumption function:
The equilibrium condition is
By substituting for C, we get
This equation can be rearranged to yield
Now solve for Y by dividing through by (1 − b):

In a balanced-budget increase, ∆G = ∆T; so in the above equation for the net initial increase in spending we can substitute ∆G for ∆T.
