Answer:
The correct answer is: 2,000; 0.4
Explanation:
We can write the initial consumption function as,
C = a + bY
8,000 = a + 10,000b
a = 8,000 - 10,000b
The new consumption function is,
14,000 = a + 20,000b
Putting value of a in this function
14,000 = 8,000 - 10,000b + 20,000b
14,000 - 8,000 = 10,000b
b =
b = 0.6
Putting the value of b in the initial function,
8,000 = a + 10,000 0.6
a = 8,000 - 6,000
a = $2,000
The marginal propensity to consume or b is 0.6.
The marginal propensity to save will be
= 1 - 0.6
= 0.4
