2 People with higher incomes enjoy higher standards of living. To judge whether the economy is doing well, we look at the total income that everyone in the economy is earning. Gross Domestic Product GDP measures the total income of a nation. GDP is thought to be the best single measure of economic well being. GDP measures the total income of everyone in the economy and the total expenditure on the economy s output. For an economy as whole, every dollar of spending by some buyer is a dollar of income for some seller. Sherif Khalifa () National Income 2 / 28
