Inflation
• Inflation: P , $ value
• Deflation: P , $ value
• Stagflation: recession + inflation at same time.
• For the last 50 years, the U.S. has had an avg. inflation rate of 4% /yr.

• Are their any exceptions to your answer? When?

• You get a raise of 5% this year.
• But inflation was 5% this year.
• Your nominal pay rose.
• What happened to your PURCHASING POWER???

Stories of extreme inflation
Note those who are helped, and those who are hurt.

Story Time
• Once upon a time in Burgerland…
• There were only four jobs:– Beefers (cowboys)– Bakers– Burger store managers– Bankers
• And only one product…
• BURGERS.
![Page 37: Grab a Calculator](https://reader037.vdocument.in/reader037/viewer/2022102800/5681328d550346895d9923a3/html5/thumbnails/37.jpg)
For as long as anyone can remember…
• The price of a burger has been $1.
• All of the burger joints voluntarily charge $1.
![Page 38: Grab a Calculator](https://reader037.vdocument.in/reader037/viewer/2022102800/5681328d550346895d9923a3/html5/thumbnails/38.jpg)
Bill the baker wants to expand his business
• So he borrows – $10 from Brenda the banker, – at 20% simple interest (fixed rate),– to be paid back in one year.
• That’s $12!• What is Brenda’s profit?• How many burgers will Brenda be able to
buy with her profits?• (All of the burger joints voluntarily
charge $1.)
![Page 39: Grab a Calculator](https://reader037.vdocument.in/reader037/viewer/2022102800/5681328d550346895d9923a3/html5/thumbnails/39.jpg)
But, before Bill is due to pay Brenda…
• The burger store managers (Bruce, Belinda, Barry, and Bedelia) unexpectedly raise their prices from $1 to $2 a burger!!
• Who is hurt by this change of events?• Who is helped?• How could Brenda have kept from getting hurt?
![Page 40: Grab a Calculator](https://reader037.vdocument.in/reader037/viewer/2022102800/5681328d550346895d9923a3/html5/thumbnails/40.jpg)
If Brenda had charged
• 20% interest
• PLUS
• the rate of inflation (called an adjustable rate loan)
• She would have come out better.
• Prices doubled. That’s 100% inflation.
• A loan of $10, paid back plus 120% interest would be $22

– They sold me a bond, so they’re borrowing from me.
• Dividends are profits paid to stockholders. When prices rise, dividends rise.
• Income tax is a percentage of your income.– When prices rise, incomes rise.

Math Review
• Percent Change
• the formula: [(new-old)/old] X 100
• so if something increases from 5 to 7, the percent change is
• [(7-5)/5] = 0.4 = 40%

Constructing a Price Index-Continued
