10. Two simultaneous effects of a wage change Income effect: Change in leisure demand caused by a change in income, holding the wage rate constant If leisure is a normal good, an increase in income increase leisure demand and lowers labor supply. Substitution effect: Change in leisure demand caused by change in wage rate, holding utility constant. An increase in wage lowers leisure demand

11. Response to a wage increase Income effect toward goods toward leisure (away from hours of work) Substitution effect toward goods away from leisure (toward hours of work) Total toward goods leisure demand (labor supply) ambiguous

12. Response to a wage increase Income effect toward goods toward leisure (away from hours of work) Substitution effect toward goods away from leisure (toward hours of work) Total toward goods toward leisure demand (away from labor supply) Backward-bending labor supply: If income effect dominates substitution effect, a wage increase lowers labor supply

13. Response to a wage increase Income effect toward goods toward leisure (away from hours of work) Substitution effect toward goods away from leisure (toward hours of work) Total toward goods toward leisure demand (away from labor supply) Upward-sloping labor supply: If substitution effect dominates income effect, a wage increase raises labor supply

14. Effect depends on what happens to the budget constraint Change in slope =>substitution effect steeper=> wage increase flatter => wage decrease Change in height => income effect higher => income increasing lower => income falling

28. Iowa Unemployment Insurance Replacement rate: Percent of previous earnings that are replaced by benefit Typical is ~50% Why is replacement rate < 100%? Why is benefit conditional on being laid off or quitting for cause?

29. Iowa Unemployment Insurance In 1984, Iowa’s UI program was $304 million in the red. Interest on debt $1 million per month Proposal—continue to pay partial benefits after UI recipient finds work

30. As of 2004, Iowa UI fund was $683 million surplus 2004 Status Report On The Unemployment Insurance Trust Fund

31. Iowa Unemployment Insurance Benefit tied to previous earnings (highest quarter of previous four excluding the current and once lagged quarter ) Average weekly wage = $586 If 0 dependents, 53% of previous earnings up to $310/week 4+ dependents: 65% of previous earnings up to $381/week You can earn up to 25% of weekly benefit in earnings and still get full benefit. After that, earnings taxed at 100% until benefit is exhausted 2004 Status Report On The Unemployment Insurance Trust Fund

32. Iowa Unemployment Insurance Example Wage = $14.65/hour ($586 per week) UI Benefit = 65% of previous earnings = $380 25% of benefit = $95 = max allowable labor earnings Possible part-time job = $9.50/hour 2004 Status Report On The Unemployment Insurance Trust Fund
