5、 Chapter 13 Types of TaxesThe marginal tax rate is the additional tax paid on an additional dollar of income.The average tax rate is the ratio of total taxes paid to total income.lAn important property of the U.S.federal individual income tax is that the marginal tax rate rises with income.8Macroeco

22、The net effect on the supply of labor is not so large.30Macroeconomics Chapter 13 An Increase in Government Purchases Financed by a Labor Income TaxEmpirically,the overall effect from permanently increased government purchases,G,on the quantity of labor supplied,Ls,seems to be small.31Macroeconomics
