InflationWho determines the prices?
Who is in the position to change the prices?
Firms charge a prices higher than the wage cost:
P = (1+m) W
Price of output = (1 + markup rate)* wage
Example: a simple pricing rule for a barbershop
Hairdresser’s wage rate per customer = $30
Mark-up rate = 50%
Find the haircut price!
The hairdresser’s wage rate per customer = $30
The markup rate was 50%, but the owner of the shop decided to raise the markup rate
to 70%
What will be the new price of a haircut?
The hairdresser’s wage rate per customer was $30.
The mark-up rate is 50%, but the owner of the shop decides to raise wages for
hairdressers, so the new wage rate per haircut is not $50.
What will be the new price of a haircut?
