(a) Suppose the natural rate of unemployment for the economy is 5 percent and the economy is currently experiencing an 8 percent unemployment rate. Explain what will likely happen to wages and prices as the economy adjusts to the long-run equilibrium. (b) Using the information below, explain the adjustments that will be taken by firms and workers to move the economy to a long-run equilibrium, specifically in terms of costs of production, real and nominal wages, and prices of products. Assume that firms and workers have adaptive expectations. The current unemployment rate = 4%. The natural rate of unemployment = 5%. Last year's inflation rate = 2%. This year's inflation rate = 3%. (c) The workers in the oil and gas industry in Alberta are paid an average of $68.50 per hour, and through their collective bargaining agreement, they have incorporated a 3.5 percent annual raise in their contracts to account for anticipated inflation. Suppose there is unexpected inflation of 2.8% percent instead. Explain how this will affect the real wages of these workers and the unemployment rate of these workers
