HOW WOULD UNEMPLOYMENT AFFECT INFLATION?
DEFICIT SPENDING
-Increases in government debts drives down the value of
the dollar (purchasing power)
- If the value of decreases it takes more $’s to purchase
the item.
- Monetizing the Debt, aka printing more $’s
- Inflating your way out of debt.

PROBLEMS AND APPLICATION
P 544; Problems… #1,#6
WAS BABE RUTH’S SALARY GOOD COMPARED
TO TODAY’S PLAYERS?
Babe’s 1931 salary - $81,000
CPI 1931 – 15.2
CPI 2005 – 195
Amount in today’s $’s = (P level today/P level in year T) * 81,000
GRAPHING PRACTICE
Show the following on an aggregate demand (AD)
aggregate supply (AS)
• What is the effect on price levels and GDP if personal income taxes
are increased?
• Same for a decrease?
• Could the government use tax rates to influence the economy?
• What is the effect on price levels and GDP if energy costs
increase?
Show the following on a money market graph:
 What does an increase in the money supply do to
nominal interest rate and price levels? What is the
likely affect on the economy?
