Question
Consider the following economy:(1) C = 1000 + 0.3 (Y - T)(2) I = 700(3) G = 500(4) T = 400What is the marginal propensity to consume?
Solution 1
To find the marginal propensity to consume (MPC), we need to look at the consumption function (C) in the given economy. The consumption function is represented by the equation C = 1000 + 0.3(Y - T), where C is consumption, Y is income, and T is taxes.
The MPC represents the change in consumption for a given change in income. In this case, the MPC is the coefficient of (Y - T) in the consumption function.
From the given equation, we can see that the coefficient of (Y - T) is 0.3. Therefore, the marginal propensity to consume in this economy is 0.3.
Solution 2
To find the marginal propensity to consume (MPC), we need to look at the consumption function (C) in the given economy. The consumption function is represented by the equation C = 1000 + 0.3(Y - T), where C is consumption, Y is income, and T is taxes.
The MPC represents the change in consumption for a given change in income. In this case, the MPC is the coefficient of (Y - T) in the consumption function.
From the given equation, we can see that the coefficient of (Y - T) is 0.3. Therefore, the marginal propensity to consume in this economy is 0.3.
