6. What is Inflation?
Inflation is rising general level of prices and it reduces the “purchasing power” of money
Examples:
It takes $2 to buy what $1 bought in 1987
It takes $6 to buy what $1 bought in 1970
It takes $24 to buy what $1 bought in 1913
When inflation occurs, each dollar of income will buy fewer goods than before

7. Is Inflation Good or Bad?

8. Good or Bad? What about deflation?
In general, ramped inflation is bad because banks don’t lend and people don’t save.
This decreases investment and GDP.
What about deflation?
Deflation- Decrease in general prices or a negative inflation rate.
Deflation is bad because people will hoard money (financial assets)
This decreases consumer spending and GDP.
Disinflation- Prices increasing at slower rates

9. But inflation doesn’t effect everyone equally.
Identify which people are helped and which are hurt by unanticipated inflation
A man who lent out $500 to his friend in 1960 and gets paid back in 2015.
A tenant who is charged $850 rent each year.
An elderly couple living off fixed retirement payments of $2000 a month
A man that borrowed $1,000 in 1995 and paid it back in 2014.
A women who saved $500 in 1950 by putting it under her mattress

10. Effects of Unanticipated Inflation
Hurt by Inflation Helped by Inflation
Lenders-People who lend money (at fixed interest rates)
People with fixed incomes
Savers
Borrowers-People who borrow money
A business where the price of the product increases faster than the price of resources
Nominal Wage- Wage measured by dollars rather than purchasing power
Real Wage- Wage adjusted for inflation
If there is inflation, you must ask your boss for a raise

13. Measuring Inflation
Copyright
ACDC Leadership 2015

14. How is inflation measured?
The government tracks the prices of specific “market baskets” that included the same goods and services.
There are two ways to look at inflation over time:
The Inflation Rate- The percent change in prices from year to year
Price Indices- Index numbers assigned to each year that show how prices have changed relative to a specific base year.
Examples:
The U.S. inflation rate in 2014 was 0.8%.
The Consumer Price Index for 2014 was 235 (base year 1982). This means that prices have increased 135% since 1982.

ACDC Leadership 2015

15. Consumer Price Index (CPI)
The most commonly used measurement of inflation for consumers is the Consumer Price Index (CPI)
Here is how it works:
The base year is given an index of 100
To compare, each year is given an index # as well =
Price of market
basket in base year
x 100
CPI
Price of market basket
Market Basket: Movie is $6 & Pizza is $14
Total = $20 (Index of Base Year = 100)
Market Basket: Movie is $8 & Pizza is $17
Total = $25 (Index of )
125
This means inflation increased 25% b/w ’97 & ‘09
Items that cost $100 in ’97 cost $125 in ‘09

17. Problems with the CPI
Substitution Bias- As prices increase for the fixed market basket, consumers buy less of these products and more substitutes that may not be part of the market basket. (Result: CPI may be higher than what consumers are really paying)
New Products- The CPI market basket may not include the newest consumer products. (Result: CPI measures prices but not the increase in choices)
Product Quality- The CPI ignores both improvements and decline in product quality. (Result: CPI may suggest that prices stay the same though the economic well being has improved significantly)

22. CPI vs. GDP Deflator
The GDP deflator measures the prices of all goods produced, whereas the CPI measures prices of only the goods and services bought by consumers.
An increase in the price of goods bought by firms or the government will show up in the GDP deflator but not in the CPI.
The GDP deflator includes only those goods and services produced domestically. Imported goods are not a part of GDP and therefore don’t show up in the GDP deflator. =

In an economy, Real GDP (base year = 1996) is $100 billion and the Nominal GDP is $150 billion. Calculate the GDP deflator.
In an economy, Real GDP (base year = 1996) is $125 billion and the Nominal GDP is $150 billion. Calculate the GDP deflator.
In an economy, Real GDP for year 2002 (base year = 1996) is $200 billion and the GDP deflator 2002 (base year = 1996) is Calculate the Nominal GDP for 2002.
In an economy, Nominal GDP for year 2005 (base year = 1996) is $60 billion and the GDP deflator 2005 (base year = 1996) is 120. Calculate the Real GDP for 2005.

What two things cause prices to increase? Use Supply and Demand
Copyright
ACDC Leadership 2015

31. 3 Causes of Inflation
1. The Government Prints TOO MUCH Money (The Quantity Theory)
Governments that keep printing money to pay debts end up with hyperinflation.
Result: Banks refuse to lend so investment falls and people don’t save up to buy things.
Examples:
Bolivia, Peru, Brazil
Germany after WWI
Copyright
ACDC Leadership 2015

32. Quantity Theory of Money
If the real GDP in a year is $400 billion but the amount of money in the economy is only $100 billion, how are we paying for things?
The velocity of money is the average times a dollar is spent and re-spent in a year.
How much is the velocity of money in the above example?
Quantity Theory of Money Equation:
M x V = P x Y
M = money supply P = price level
V = velocity Y = quantity of output
Notice that P x Y is Nominal GDP
Copyright
ACDC Leadership 2015

33. M x V = P x Y Why does printing money lead to inflation?
Assume the velocity is relatively constant because people's spending habits are not quick to change.
Also assume that output (Y) is not affected by the amount of money because it is based on production, not the value of the stuff produced.
If the govenment increases the amount of money (M) what will happen to prices (P)?
Ex: Assume money supply is $5 and it is being used to buy 10 products with a price of $2 each.
1. How much is the velocity of money?
2. If the velocity and output stay the same, what will happen if the amount of money is increase to $10?
Notice, doubling the money supply doubles prices 33

35. Higher production costs increase prices
3 Causes of Inflation
2. Demand- Pull Inflation
DEMAND PULLS UP PRICES!!!
“Too many dollars chasing too few goods”
An overheated economy with excessive spending but same amount of goods.
3. Cost-Push Inflation
Higher production costs increase prices
A negative supply shock increases the costs of production and forces producers to increase prices.

36. The Wage-Price Spiral A Perpetual Process: 1.Workers demand raises
2.Owners increase prices to pay for raises
3. High prices cause workers to demand higher raises
4. Owners increase prices to pay for higher raises
5. High prices cause workers to demand higher raises
6. Owners increase prices to pay for higher raises

37. Nominal vs. Real Interest Rates
Copyright
ACDC Leadership 2015

38. Interest Rates and Inflation
What are interest rates? Why do lenders charge them?
Who is willing to lend me $100 if I will pay a total interest rate of 100%?
(I plan to pay you back in 2050)
If the nominal interest rate is 10% and the inflation rate is 15%, how much is the REAL interest rate?
Real Interest Rates-
The percentage increase in purchasing power that a borrower pays. (adjusted for inflation)
Real = nominal interest rate - expected inflation
Nominal Interest Rates-
the percentage increase in money that the borrower pays not adjusting for inflation.
Nominal = Real interest rate + expected inflation
Copyright
ACDC Leadership 2015

39. Nominal vs. Real Interest Rates
Example #1:
You lend out $100 with 20% interest. Inflation is 15%.
A year later you get paid back $120.
What is the nominal and what is the real interest rate?
Nominal interest rate is 20%. Real interest rate was 5%
In reality, you get paid back an amount with less purchasing power.
Example #2:
You lend out $100 with 10% interest. Prices are expected to increased 20%. In a year you get paid back $110.
Nominal interest rate is 10%. Real rate was –10%

40. Achieving the Three Goals
The governments role is to prevent unemployment and prevent inflation at the same time.
If the government focuses too much on preventing inflation and slows down the economy we will have unemployment.
If the government focuses too much on limiting unemployment and overheats the economy we will have inflation
