Quizplus · Accepted Answer

Marginal propensity to consume (MPC) is the change in consumption as a result of a change in disposable income. 
To calculate MPC, we need to find the change in consumption and the change in disposable income between two points. 
Using the data from the table, we can see that between the first two points, disposable income increased by 0.6 (from 2.1 to 2.7) and consumption increased by 0.4 (from 2.0 to 2.4). 
Therefore, MPC is 0.4/0.6 = 2/3.
Similarly, between the second and third points, disposable income increased by 0.6 and consumption increased by 0.4, giving an MPC of 2/3.
Between the third and fourth points, the MPC is also 2/3. Therefore, the MPC is constant at 2/3 for this data set.

For the best choice(s), we need to see the options given.
