(con’t) possible factors we could measure: (b) expenditure approach – gov’t adds up all the money spent on buying this year’s output (c) output – gov’t determines value added…the money spent on making goods (inputs) is deducted from money received from sale of goods (output).

Most countries have settled on the expenditure method where gov’t adds up all the money spent on buying this year’s output. Primary measure: Real GDP – real gross domestic product the total market value of all final goods and services produced in an economy in a one-year period

GNP – gross national product Since 1992 we’ve used -- GDP – gross domestic product the total market value of all final goods and services produced in an economy in a one-year period; a geographic measure another possible measure… aggregate final output of citizens and businesses of an economy in a one-year period; a citizenship measure
