Unformatted text preview: n are willing to ¯ work. Firms bid up the real wage w to attract workers. ◮ If w > w firms find more workers willing to work than firms ¯ care to hire. Jobseekers drive down the real wage. Upshot: the labor market moves toward equilibrium (w , N ). ¯¯ Frictional and Structural Unemployment ◮ Problem with supply and demand model above. No worker who wishes to work another hour at the prevailing wage w is unable to find an employer. ¯ Unemployment (defined as people looking for work but not working) would be zero! ◮ How can this be? ◮ Supply and demand is a useful way of thinking about the determination ¯ of w and N but doesn’t tell the whole story. ¯ ◮ Example Landlords and tenants ◮ Frictional unemployment – unemployment that arises from the matching process of workers searching for suitable jobs and firms searching for suitable employees. ◮ Structural unemployment – long-term and chronic unemployment arising from imbalances in skills and characteristics of workers and the needs of firms.

Potential Output ¯ ¯ Y = AF (K , N ) (1) ¯ where N is the market clearing quantity in labor market. ◮ Key Assumption N is determined today. K is determined in the previous time period. That is, it takes time to build machinery and structures. This assumption is maintained throughout the course. ◮ ¯ ¯ Anything that changes N will change Y The Costs of Unemployment ◮ Economic costs ◮ Periods of cyclical unemployment are times of depressed output the economy could produce more at full employment (potential output) ◮ Broader costs ◮ ◮ Psychological rise in stress and mental illness ◮ Human capital those who are unemployed experience a deterioration in skills Equity ◮ ◮ The costs fall on those who are unemployed These costs fall heavily on specific groups...
