Assume Sasha has a flexible job that pays $50/hour, and her utility maximizing labor supply is to work 40 hours/week for 50 weeks/year. Thus her annual income is $100,000. Suppose that Sasha receives a promotion that raises her wage to $55/hour. On the same day, the President signs a bill that makes tax credits for homeowners less generous, which will cause Sasha's annual income tax payment to increase by $10,000. Will the combina- tion of the promotion and the tax bill cause Sasha's to work more hours, fewer hours, or is the effect ambiguous? Explain your reasoning.
