Expert Solution & Answer

Answer to Problem 10PS

To determine the effect of desired revision and compare the results of such changes, first we will consider the spreadsheet 21.5 as it will form the base of our answer.

This sheet is prepared with the assumption that desired real consumption is taken as input from previous spreadsheet. Taxes are then calculated on nominal consumption minus the necessary exemption. Thus, savings comes as a residuary information nominal income minus the tax minus the nominal consumption. The retirement section specifies that all funds in the retirement account are subject to tax.

On comparing the above results, by keeping all the conditions remaining same, and revising the given rates we reach the following conclusion:

	AS PER ACTUAL STATED CONDITION	AS PER ACTUAL STATED CONDITION AND INCREASING INFALTION RATE TO 4%	AS PER ACTUAL STATED CONDITION AND INCREASING TAX RATE TO 26%
REAL CONSUMPTION	76,052.00	16,040.00	74,436.00
REAL CONSUMPTION ON RETIREMENT	60,789.00	15,780.00	58,983.00

Hence we can say, on increasing inflation rate by 1%, the real consumption decreases marginally.

Question

Chapter 21, Problem 10PS

Summary Introduction

To determine:

The effect on real consumption during retirement of a 1% increase in the rate of inflation to a 1% increase in the tax rate as per given spread sheet 21.5.

Introduction:

Tax shelters are ways and means by which it is possible to postpone the payment of liability for as long as possible.

Expert Solution & Answer

Answer to Problem 10PS

To determine the effect of desired revision and compare the results of such changes, first we will consider the spreadsheet 21.5 as it will form the base of our answer.

This sheet is prepared with the assumption that desired real consumption is taken as input from previous spreadsheet. Taxes are then calculated on nominal consumption minus the necessary exemption. Thus, savings comes as a residuary information nominal income minus the tax minus the nominal consumption. The retirement section specifies that all funds in the retirement account are subject to tax.

Number of retirement years	25
Income growth rate	7%
Rate of return	6%
Income at age 30	50,000
Savings Rate	15%
Inflation Rate	4%
Exemption	$15,000

On comparing the above results, by keeping all the conditions remaining same, and revising the given rates we reach the following conclusion:

	AS PER ACTUAL STATED CONDITION	AS PER ACTUAL STATED CONDITION AND INCREASING INFALTION RATE TO 4%	AS PER ACTUAL STATED CONDITION AND INCREASING TAX RATE TO 26%
REAL CONSUMPTION	76,052.00	16,040.00	74,436.00
REAL CONSUMPTION ON RETIREMENT	60,789.00	15,780.00	58,983.00

Hence we can say, on increasing inflation rate by 1%, the real consumption decreases marginally.

Question

Chapter 21, Problem 10PS

Summary Introduction

To determine:

The effect on real consumption during retirement of a 1% increase in the rate of inflation to a 1% increase in the tax rate as per given spread sheet 21.5.

Introduction:

Tax shelters are ways and means by which it is possible to postpone the payment of liability for as long as possible.

Expert Solution & Answer

Answer to Problem 10PS

To determine the effect of desired revision and compare the results of such changes, first we will consider the spreadsheet 21.5 as it will form the base of our answer.

This sheet is prepared with the assumption that desired real consumption is taken as input from previous spreadsheet. Taxes are then calculated on nominal consumption minus the necessary exemption. Thus, savings comes as a residuary information nominal income minus the tax minus the nominal consumption. The retirement section specifies that all funds in the retirement account are subject to tax.

On comparing the above results, by keeping all the conditions remaining same, and revising the given rates we reach the following conclusion:

	AS PER ACTUAL STATED CONDITION	AS PER ACTUAL STATED CONDITION AND INCREASING INFALTION RATE TO 4%	AS PER ACTUAL STATED CONDITION AND INCREASING TAX RATE TO 26%
REAL CONSUMPTION	76,052.00	16,040.00	74,436.00
REAL CONSUMPTION ON RETIREMENT	60,789.00	15,780.00	58,983.00

Hence we can say, on increasing inflation rate by 1%, the real consumption decreases marginally.

Answer 4

Question

Chapter 21, Problem 10PS

Summary Introduction

To determine:

The effect on real consumption during retirement of a 1% increase in the rate of inflation to a 1% increase in the tax rate as per given spread sheet 21.5.

Introduction:

Tax shelters are ways and means by which it is possible to postpone the payment of liability for as long as possible.

Expert Solution & Answer

Answer to Problem 10PS

To determine the effect of desired revision and compare the results of such changes, first we will consider the spreadsheet 21.5 as it will form the base of our answer.

This sheet is prepared with the assumption that desired real consumption is taken as input from previous spreadsheet. Taxes are then calculated on nominal consumption minus the necessary exemption. Thus, savings comes as a residuary information nominal income minus the tax minus the nominal consumption. The retirement section specifies that all funds in the retirement account are subject to tax.

On comparing the above results, by keeping all the conditions remaining same, and revising the given rates we reach the following conclusion:

	AS PER ACTUAL STATED CONDITION	AS PER ACTUAL STATED CONDITION AND INCREASING INFALTION RATE TO 4%	AS PER ACTUAL STATED CONDITION AND INCREASING TAX RATE TO 26%
REAL CONSUMPTION	76,052.00	16,040.00	74,436.00
REAL CONSUMPTION ON RETIREMENT	60,789.00	15,780.00	58,983.00

Hence we can say, on increasing inflation rate by 1%, the real consumption decreases marginally.

Answer 5

Chapter 21, Problem 10PS

Summary Introduction

To determine:

The effect on real consumption during retirement of a 1% increase in the rate of inflation to a 1% increase in the tax rate as per given spread sheet 21.5.

Introduction:

Tax shelters are ways and means by which it is possible to postpone the payment of liability for as long as possible.

Expert Solution & Answer

Answer to Problem 10PS

To determine the effect of desired revision and compare the results of such changes, first we will consider the spreadsheet 21.5 as it will form the base of our answer.

This sheet is prepared with the assumption that desired real consumption is taken as input from previous spreadsheet. Taxes are then calculated on nominal consumption minus the necessary exemption. Thus, savings comes as a residuary information nominal income minus the tax minus the nominal consumption. The retirement section specifies that all funds in the retirement account are subject to tax.

For the first part of the answer where we have to calculate effect of 1% increase in inflation on real consumption, we have considered the following assumption:

Number of retirement years	25
Income growth rate	7%
Rate of return	6%
Income at age 30	50,000
Savings Rate	15%
Inflation Rate	4%
Exemption	$15,000
Tax rate	25%

On comparing the above results, by keeping all the conditions remaining same, and revising the given rates we reach the following conclusion:

	AS PER ACTUAL STATED CONDITION	AS PER ACTUAL STATED CONDITION AND INCREASING INFALTION RATE TO 4%	AS PER ACTUAL STATED CONDITION AND INCREASING TAX RATE TO 26%
REAL CONSUMPTION	76,052.00	16,040.00	74,436.00
REAL CONSUMPTION ON RETIREMENT	60,789.00	15,780.00	58,983.00

Hence we can say, on increasing inflation rate by 1%, the real consumption decreases marginally.

Answer 6

Chapter 21, Problem 10PS

Summary Introduction

To determine:

The effect on real consumption during retirement of a 1% increase in the rate of inflation to a 1% increase in the tax rate as per given spread sheet 21.5.

Introduction:

Tax shelters are ways and means by which it is possible to postpone the payment of liability for as long as possible.

Expert Solution & Answer

Answer to Problem 10PS

To determine the effect of desired revision and compare the results of such changes, first we will consider the spreadsheet 21.5 as it will form the base of our answer.

This sheet is prepared with the assumption that desired real consumption is taken as input from previous spreadsheet. Taxes are then calculated on nominal consumption minus the necessary exemption. Thus, savings comes as a residuary information nominal income minus the tax minus the nominal consumption. The retirement section specifies that all funds in the retirement account are subject to tax.

On comparing the above results, by keeping all the conditions remaining same, and revising the given rates we reach the following conclusion:

	AS PER ACTUAL STATED CONDITION	AS PER ACTUAL STATED CONDITION AND INCREASING INFALTION RATE TO 4%	AS PER ACTUAL STATED CONDITION AND INCREASING TAX RATE TO 26%
REAL CONSUMPTION	76,052.00	16,040.00	74,436.00
REAL CONSUMPTION ON RETIREMENT	60,789.00	15,780.00	58,983.00

Hence we can say, on increasing inflation rate by 1%, the real consumption decreases marginally.

Answer 7

Chapter 21, Problem 10PS

Summary Introduction

To determine:

The effect on real consumption during retirement of a 1% increase in the rate of inflation to a 1% increase in the tax rate as per given spread sheet 21.5.

Introduction:

Tax shelters are ways and means by which it is possible to postpone the payment of liability for as long as possible.

Answer 8

Expert Solution & Answer

Answer to Problem 10PS

To determine the effect of desired revision and compare the results of such changes, first we will consider the spreadsheet 21.5 as it will form the base of our answer.

This sheet is prepared with the assumption that desired real consumption is taken as input from previous spreadsheet. Taxes are then calculated on nominal consumption minus the necessary exemption. Thus, savings comes as a residuary information nominal income minus the tax minus the nominal consumption. The retirement section specifies that all funds in the retirement account are subject to tax.

On comparing the above results, by keeping all the conditions remaining same, and revising the given rates we reach the following conclusion:

	AS PER ACTUAL STATED CONDITION	AS PER ACTUAL STATED CONDITION AND INCREASING INFALTION RATE TO 4%	AS PER ACTUAL STATED CONDITION AND INCREASING TAX RATE TO 26%
REAL CONSUMPTION	76,052.00	16,040.00	74,436.00
REAL CONSUMPTION ON RETIREMENT	60,789.00	15,780.00	58,983.00

Hence we can say, on increasing inflation rate by 1%, the real consumption decreases marginally.
