Problem Set 6 Consider the following schedule: Disposable Income Consumption $10,000 $11,000 $15,000 $15,000 $20,000 $18,500 $25,000 $21,500 $30,000 $24,000 $35,000 $25,500 $40.000 $26,500 a. For each level of disposable income, calculate the level of net saving (i.e., saving or dissaving). b. For each increment in income (i.e., from $10,000 to $15,000, etc.), calculate the marginal propensity to consume (MPC). C. For each increment in income, calculate the marginal propensity to save (MPS). d. What is the sum of MPS and MPC? Why
