Use the data below to calculate GDP using the expenditure approach. (I intentionally left GDP = $ 5555.1 Billion out some of the income categories so that you must use the expenditure approach). Then calculate NDP, NI, PI, and DI. (All figures are in billions of dollars): NDP = $ 4994 Billion Consumption of Fixed Capital (Depreciation) 561.1 NI = $ 4635.2 Billion Corporate Income Taxes 131.5 PI = $ 4473.4 Billion Dividends 109.2 Exports 468.3 DI = $ 3904.8 Billion Government Purchases 1099.5 Imports 588.7 Indirect Business Taxes 320.2 Interest 408.2 Net foreign factor income earned in the U.S. 38.6 Gross Private Domestic Investment 834.3 Personal Consumption Expenditure 3741.7 Personal Taxes 568.6 Proprietor's Income 333.8 Rents 38.4 Social Security Contributions 357.8 Transfer Payments 487.2 Undistributed Corporate Profits 159.7
