When above the 5% average, this is the cause and that is bad b) EXAMPLE: a. At least ½ unemployment rate is chronic unemployment i. 100 people story: 1 chronic, 12 unemployed 1 each month 1. 2%, 1% caused by the chronic 5. Nominal (W) vs. Real Wages (W/P) a) Nominal wage rate a. Given unit of time of work b. it is a upper case W b) Real Wage a. Use P (CPI of a point in time i.e. the price of living) i. Used more often to see real wage worth  ii. W/P or lowercase W 6. Cost of Inflation P (t+1 −P(t) a) ∗100=π  (This is the inflation RATE) P(t) a. P is CPI again. P(t) is today, P(t+1) is tomorrow  b) Expected inflation a. Opportunity to prepare for this inflation b. The expected costs are just small changes i. Cost of carrying money in high inflation countries is huge 1.

Doesn’t give the cost of inflation or anything like that b) Real: lower case r a. #goods you consume tomorrow= #goods today D t+1 ) ( 1+i∗D(t) i. P(t+1) = 1+π ∗P(t)  (These are the equations related to  those words above.) ii. SO for REAL interest rates: D (t+1 ) D(t) 1. = (1+r) P(t+1) P(t) b. i = r + π  i. As long as all are small. This is the Fisher Equation
