If income goes up then consumption will go up and savings will go up. Investments are not made when interest rate exceeds the expected rate of return (r < i). As with consumption, we will assume that this relationship is linear: In this equation the intercept is e, the autonomous level of Savings. How stable is the beta estimate? The marginal propensity to consume (abbreviated MPC) is another term for the slope of the consumption line and is calculated as the change in consumption divided by the change in income.

The consumption function can be calculated using a simple formula: C = A + MD where C is the consumer spending, A is autonomous consumption (spending regardless of income levels), M is the marginal propensity to consume (the amount of additional income needed to spend on goods and services rather than saving it), and D is the amount of real disposable income required. Additional comment on this is. What is the initial unplanned inventory investment? The consumption function is represented as: C = A + MD. = D) the two are always .
