Winners and losers from unexpected inflation Case 1: Wage contracts Consider the following scenario: (1)The time 1 CPI is =100. (2)At time 1 an employer and employee agree to a wage contract paying the worker a time 2 nominal wage of =$10/labor. (3)Each party to the wage contract expects inflation from time 1 to time 2 to be 5%. That is, each party expects the time 2 CPI to be expected time 2 CPI= = 105. Defining the price level to be CPI/100, one finds that the time 2 expected price level is =1.05 (4)Given (2) and (3), it follows that each party to the contract expects the time 2 real wage to be: expected time 2 real wage = = / = $10/(1.05) (≈$9.53). (5) Actual inflation from time 1 to time 2 is 10%. So the actual CPI at time 2 is actual time 2 CPI = =110. The actual, realized price level is =1.10. (6)The actual real wage is actual time 2 real wage = / =$10/(1.10) (≈$9.10). (7)The worker has an unexpected loss of unexpected real loss =$10/(1.05)- $10/(1.10) ≈ $0.43. The loss represents the difference between the
