Answer to Problem 4NP

For the earning $16,000 , the average tax rate is 12.5% and the marginal tax rate is 25% and for the earning $30,000 , the average tax rate is 20% and the marginal tax rate is 30% .

Explanation of Solution

Given is the tax slab of individuals,

    Below$8,0000%
    From$8,000 to$20,00025%
    Above$20,00030%

For calculation of average tax rate the formula is given here:

A=TaxpaidTotalIncome×100

For the person earning $16,000 , the average tax rate will be:

=0.25($16,000-$8,000)$16,000×100=$2000$16000×100=12.50%

Since, the person is earning $16,000 , hence, initial $8,000 tax rate is 0% or exempt, and above $8,000 remaining $8,000 is taxed at the rate of 25% . Therefore, the marginal tax rate for the person is 25% .

For the person earning $30,000 , the average tax rate will be:

=(0.25×$12,000+0.30×$10,000)$30,000×100=$6,000$30,000×100=20%

Since, the person is earning $30,000 , hence, up to $8,000 tax rate is 0% or exempt, and above $8,000 , he is taxed at the rate of 25% on $12,000 ($20,000$8,000) and 30% on $10,000 ($30,000$20,000) . Therefore, the marginal tax rate for the person is 30% .

Economics Concept Introduction

Introduction: The government gets the fund from the taxes and borrowings for expenditure purposes like government consumption, investment, national defense, public health, etc. Government changes these tax slabs time to time to give relief to the persons earning lower incomes or charge extra taxes sometimes from the taxpayers.

Answer to Problem 4NP

For the earning $16,000 , the average tax rate is 12.5% and the marginal tax rate is 20% and for the earning $30,000 , the average tax rate is 19.33% and the marginal tax rate is 30% .

Explanation of Solution

Given is the tax slab of individuals,

    Below$6,0000%
    From$6,000 to$20,00020%
    Above$20,00030%

For calculation of average tax rate the formula is given here:

A=TaxpaidTotalIncome×100

For the person earning $16,000 , the average tax rate will be:

=0.2($16,000$6,000)$16,000×100=$2000$16000×100=12.50%

Since, the person is earning $16,000 , hence, initial $6,000 tax rate is 0% or exempt, and above $6,000 remaining $10,000 is taxed at the rate of 20% . Therefore, the marginal tax rate for the person is 20% .

For calculation of average tax rate the formula is given here:

A=TaxpaidTotalIncome×100

For the person earning $30,000 , the average tax rate will be:

=(0.25×$14,000+0.30×$10,000)$30000×100=($2,800+$3,000)$30,000×100=$5,800$30,000×100=19.33%

Since, the person is earning $30,000 , hence, initial $6,000 tax rate is 0% or exempt, and above $6,000 remaining $14,000 ($20,000$6,000) is taxed at the rate of 20% and $10,000 ($30,000$20,000) is taxed at 30% Therefore, the marginal tax rate for the person is 30% .

Answer to Problem 4NP

The tax rate lowers in part (b) will not affect the labor supply of the person initially earning $16,000 , but increase in the labor supply of the person initially earning $30,000 , since he has saved money due to lower taxes.

Explanation of Solution

A change in the marginal tax rate does not change the average tax rate of the person earning $16,000 , he is taxed at the rate of 12.5% in both the cases. Hence, the labor supply of the person will remain constant, as he was unable to save anything due to change in slab rate. Whereas, for the person earning $30,000 , there is no change in the marginal tax rate but his average tax rate earlier was 20% and after the change in slab was 19.33%. thus, the labor supply of the person will increase because he saved money due to lower average tax rate than before.
