 What is the formula for APC? Average propensity to consume (APC) = consumption/income What is the formula for APS? Average propensity to save (APS) = saving/income What is the formula for MPC? Marginal propensity to consume (MPC) = change in consumption/change in income What is the formula for MPS? Marginal propensity to save (MPS) = change in saving/change in income A schedule showing the amounts households plan to spend for consumer goods at different levels of disposable income. Consumption schedule A schedule that shows the amounts households plan to save (plan not to send for consumer goods), at different levels of disposable income.

Investment demand curve (constructed by arraying all potential investment projects in descending order of their expected rates of return) The investment demand curve reflects an ______ (_______) relationship between the real interest rate and investment and slopes _______. inverse (negative); downward The investment demand curve shifts when changes occur in: 1. The costs of acquiring, operating, and maintaining capital goods 2. Business taxes 3. Technology 4. The stock of capital goods on hand 5.

Multiplier effect
