Question

If consumer income increases by $100 million in the united states and the mpc is .6, by how much will consumption increase?

Answer 1

The marginal propensity to consume (MPC) is a measure of the proportion of extra income that will be spent on consumption. If an individual receives an extra $100 and spends $60 on consumption then the person’s MPC is 0.60. If consumer income in the United States increases by $100 million and the MPC is 0.60 consumption in the US will increase by $60 million.
