1. y 1. Disequilibrium point: Underemployment l MRS Slope of BC = w Underemployment: worker would increase utility (higher IC) by working longer hours (from A to B) l0l0 l1l1 lC 0 lC 1 A B Equilibrium y0y0 y1y1

2. y 2. More or fewer working hours? l a) Wages go up and the substitution effect is greater than the income effect  more hours (upward sloping portion of L s ) l0l0 l1l1 y0y0 y1y1 A B

3. y 2. More or fewer working hours? l b) Wages go down and the substitution effect is smaller than the income effect  more hours (backward bending portion of L s ) l1l1 l0l0 y0y0 y1y1 B A
