ECN 204 Study Guide - Output Gap, Real Interest Rate, Aggregate Supply
Document Summary
Ae is planned total spending on final goods & services; Ratio of change in equilibrium gdp to change in autonomous expenditure (investment spending) Changes in gdp = multiplier * initial change in spending. Rationale: spending generates income, change in income cause both consumption & saving to change. Multiplier = 1 / mps = 1 / (1 j mpc) Assumptions: government purchases do not cause shift in consumption/investment schedules. N net tax revenues derived totally from personal taxes; taxes do not vary with gdp. N government spending (g is autonomous expenditure), shifts ae up = higher equilibrium gdp. 2 different policies government may pursue to close gap & achieve full employment: Aggregate demand j amounts of real output that buyers collectively desire to purchase at each possible price level (inverse) Slopes downward due to these effects of change in price level: real-balances effect j inverse relationship of price & real value of financial assets with fixed money value.
