If the Government cut income taxes by 100 billion and the marginal propensity to consume (MPC) is equal to .75? How would this tax cut impact the National Budget and the National Debt? What are the pros and cons of running a deficit? Would you support such a tax cut and for whom should we impose the tax cut?

Expert Solution

The tax multiplier is : MPC/(1-MPC)

Here it's ( 0.75/1-0.75) =3

An income tax cut will lead to a generation of 100x3= 300 billion in the GDP.

The national will fall, and this will increase the deficit, thus increasing National Debt if any.

Pro : increased income and consumption, which leads to a greater growth rate in the economy

Cons: National debt increases, so is the cost of debt payment will also increase.

The tax cut can be supported, if the estimated growth rate if greater than rate at which debt is taken. The tax cut should be focused for the lower and middle income group of the economy. As this increased disposable income will lead to greater consumption. If higher income groups are given the benefit of tax cut, the effect of the multiplier will decrease, as the marginal propensity to save is higher for higher income groups.

Consider a hypothetical economy in which the marginal propensity to consume (MPC) is 0.50. That is, if disposable income increases by $1, consumption increases by 50¢. Suppose further that last year disposable income in the economy was $400 billion and consumption was $300 billion. On the following graph, use the blue line (circle symbol) to plot this economy's consumption function based on these data. 01002003004005006007008007006005004003002001000-100CONSUMPTION (Billions of dollars)DISPOSABLE INCOME (Billions of dollars)Y-Intercept: 100Slope: 0 From the preceding data, you know...

the following the average marginal propensity to consume (MPC) is c1 = .52. They then looked at how different groups had different marginal propensities to consume. In particular: For Group 1 of Italians, their MPC is c1 = .3 For Group 2 of Italians, their MPC is c1 = .65 Now, take the following hypothetical situation about the Italian economy: M = X = 0 G = 500, Tp=500 C = 1000 + c1(Y-Tp) I = 200 Round to two...

The Giladi family has a linear consumption function with a marginal propensity to consume (MPC) of 0.6, and the Sharoni family has a linear savings function with a marginal propensity to save (MPS) of 0.6. Autonomous consumption (Co) is positive, Thus: a. There is a level of income at which the Giladi family’s consumption equals savings. b. There is a level of income at which the Sharon family’s consumption equals savings. c. It is impossible to determine if in the...

Consider an economy, but don't know the marginal propensity to consume (MPC) for the average person. If the government decides to increase its government spending by 1 billion dollars in education (building more public schools, etc.) To nance the increase in government spending, the government decides to increase tax by 1 billion dollars as well. How would the GDP respond to this series of change in the Goods Market Equilibrium? Explain.
