what is CPI

(consumer price index)
a measure of the overall cost of the goods and services bought by a typical consumer

How to calculate CPI

(expenditures in the current year/expenditures in the base year) x 100

Lets say you wanted to calculate the cost of something in 1909 compared to the cost of something in 2015. How would you go about calculating this

PriceIndex2015
----------------- X The amount of money in 2015
PriceIndex1909

whats the equivalent salary in 2014 ($25,000):
CPI
1975 53.8
1983 100(Base year)
2014 236.7

236.7
------
53.8
once you do that, multiply X 25000= $109,990

in 1984 an item cost $1.00. In January of 2006 that same item cost $1.98 But let's calculate the price difference between 1984 and 2006. Whats the inflation of the item?

1.98-1.00
---------- X 100 = 98%
1.00

Ex) a mortgage Lender Loaning money to a BORROWER would BENEFIT bc the money they get back is MORE valuable

How to use the exchange rate based measure to calculate the difference in another countries currency VS. US currency?

Other countries GDP per capita X the exchange rate

What are the two ways to convert GDP in another country to a single (US) currency

Method 1- Exchange rate based measure
Method 2- Purchasing Power Parity measure (PPP) aka the big mac jawn

Convert to US currency using the following numbers thot
GDP per capita in China = $43,686 Yuan.
Exchange rate = .161

43,686 x .161 = $7,033 US currency

How to use the Purchasing Power Parity method

Other countries GDP per capita x PriceUSA/Price other country

Calculate GDP in china using the PPP method
GDP per capita=$43,686 Yuan
Price Big Mac USA= $4.79
Price Big Mac CHINA= 17.2

4.79

Increase physical Cap(k)
Increase total efficiency units of labor (H)
Improve tech (A)
