Interpreting the GDP • From the circular flow, we get: Income = Y = C + S + T Income = Expenditures Y = C + I + G + (Ex-Im) • Substitute, cancel C and rearrange to get: S + T + Im = I + G + Ex Leakages = Injections
Interpreting the GDP • Further rearrange to get: I = S + (T-G) + (Im-Ex) • Investment comes from three sources: • Private sector savings. • Government “savings.” • Foreign sector savings. • Where economic growth is primarily determined by investment . . . 2011: $2.34 t ≈ $2.83 t - $1.0 t + $570 b
GDP as the sum of “values added” • Finding C, I, G and net X is difficult. • Values are estimated based on statistical analysis. • GDP is calculated by adding up all values added. VA = (sales revenue) – (cost of inputs) • This data is obtainable from tax info.
GDP: Nominal vs. Real • Nominal = “current dollar” value • Real = “constant dollar” value
