Answer: where desired spending j called aggregate expenditure (ae) equals national income (output) Assume price level is fixed ( nominal gdp = real gdp) to simplify analysis: - households consumption (c) depends upon income (y) - savings (s) = income not consumed = y-c. Marginal-propensity-to-save (mps) = %s/%y mpc+mps=1. (for every dollar of the income is either saved or consumed;) - firms undertake investment (i) in anticipation of earning a profit; - will treat as fixed (i=25) in first example www. notesolution. com www. notesolution. com www. notesolution. com www. notesolution. com. the multiplier: concept: y = multiplier x autonomous expenditure, however, induced consumption is the key. Round #2 c = mpc x y = 0. 9 x 10 = 9 output/income = 9. Round #3 c = mpc x y = 0. 9 x 9 = 8. 1 output/income = 8. 1. Total output/income is the sum of the following geometric sequence:
