WHAT CAUSES INFLATION?

?

WHAT CAUSES INFLATION??Demand-Pull Inflation

WHAT CAUSES INFLATION??Cost-Push Inflation

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.

HOW DOES THE MONEY SUPPLY AFFECT PRICE LEVELS?

Excessive Monetary Growth causes Inflation.

- When Money Supply grows faster than GDP

High

Low

INFLATION….GOOD???? BAD????

HELPED BY INFLATION

-Borrowers with fixed payments

-Banks with fixed rate savings accounts

-Government in debt

-Fixed rate contracts

HURT BY INFLATION

-Banks with fixed rate loans

-Borrowers with adjustable rate loans

-People with fixed rate savings accounts

- People living on fixed incomes

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?
