Quantity demande d Q (Millions of Barrels per day) Change in Q (Millions of Barrels per day) Price P (Dollars per barrel) Change in P (Q1+Q2)/2 (P1+p2)/2 Ep=(Change in Q/ (Q1+Q2)/2))/(Change in P/ (P1+P2)/2) 1 98 3 80 6 77 8 74 9 70 12 68 14 65 16 60 18 58 20 56 25 45 4. Columns 1 and 2 in the table show the relationship between employment and the price level in the economy. Employment (Millions of Workers) Price Level Unemployment Rate (%) Rate of Inflation (%) 94 1.00 95 1.08 96.6 1.17 97.3 1.28 97.5 1.42 98.2 1.59 98.0 1.81 98.6 2.10 Assume that full employment in the economy occurs when 100 million workers are employed. Compute the column 3 - the unemployment rate at each level of employment. (Hint: Divide the number of workers unemployed by the number that would be employed at full employment.). At each unemployment rate compute and enter in column 4 the rate of inflation by dividing the increase in the price level by the price level. 5. Plot the Nominal and real GDP from 1996 to 2006.
