16. Debate Over Income Tax Do workers adjust their work habits as wages increase, or decrease as when taxes rise? Estimates of the tax elasticity of supply of labor services: For men 25-60, near zero. For women, large and approaching one.

17. 7. Debate Over Income Tax Workers can adjust by working overtime, by finding second jobs. Families may have second, even third earners. Those other family workers may have more flexibility than the primary earner. The elderly may have more flexibility as a result of Social Security and pensions. The Underground Economy

18. Debate Over Income Tax Tax on Consumption vs Income Some economists and a number of politicians advocate eliminating the income tax in favor of consumption taxes. Consumption could be the difference between income and amount saved. C=DI- Saving Encourages saving. But saving only postpones taxes; it does not avoid them.

19. Debate Over Income Tax Is income or consumption tax fairer? In the long-run, the tax burden of a consumption tax may be greater than an income tax. Transition from income to consumption tax is a problem. Relative efficiency of the two depends on elasticity of labor supply and tax elasticity of saving.
