The accompanying table shows Tom and Ray's total willingness to pay for different amounts of public recreational areas (REC), which is measured in acres. The marginal cost of one acre of recreational area is $1,000.
Tom's willingness to pay Ray's willingness to pay REC (acres)
$2,000 $1,000 1
3,000 1,800 2
3,800 2,500 3
4,300 3,100 4
4,500 3,600 5

Part A: What is the socially optimal level of recreational areas? Assume you cannot purchase partial acres. Explain your answer.
Part B: What should be the tax burden to Tom and Ray so that their consumer surpluses are equal? Explain.
Part A : size of socially optimal recreational area is 4 acre
Part B : Tom's tax burden is $2,600 and Ray's Tax burden is $1,400
Explanation:-
Part A : Compute socially optimal recreational area
Compute Marginal willingness to pay for both Tom and Ray for each of the acre size
Marginal willingness to pay for X acres = Willingness to pay for X acres -
Willingness to pay for X-1 acres
Using this formula, the Marginal willingness to pay for both Tom and Ray are computed and populated in the table below for each of the acre size
Compute total willingness to pay for each of the acre size
Total Willingness to pay = Tom's willingness to pay + Ray's willingness to pay
Using this formula, the table below is populated for each of the acre size
Socially optimal level is one beyond which Marginal cost (MC) just goes over the Total Marginal willingness to pay
Total Marginal Willingness to Payacre size >= MCacre size
Total Marginal Willingness to Pay4 acre size > MC4 acre size
Total Marginal Willingness to Pay5 acre size < MC5 acre size
Thus socially optimal level of recreational areas is 4 acre
Part B : Compute tax burden
At 4 acre, Tom is willing to pay = $4,300
Tom's tax burden = TaxTom
Tom's consumer surplus = $4,300 - TaxTom
At 4 acre, Ray is willing to pay = $3,100
Ray's tax burden = TaxRay
Ray''s consumer surplus = $3,100 - TaxRay
Tom and Ray's consumer surplus are equal
$4,300 - TaxTom = $3,100 - TaxRay ------------------ Eq1
Total Cost of the 4 acre REC = 4 * MC = 4* $1,000 = $4,000
Total Tax = Total Cost
TaxTom + TaxRay = $4,000 ------------------ Eq2
Solve two equations and two variables
Adding left and right sides of Eq1 and Eq2
$4,300 - TaxTom + TaxTom + TaxRay = $3,100 - TaxRay + $4,000
TaxRay + TaxRay = $3,100+ $4,000 - $4,300
2 * TaxRay = $2,800
TaxRay = $2,800 / 2 = $1,400
Sbstituting this value of TaxRay in Eq2
TaxTom + $1,400 = $4,000
TaxTom = $4,000 - $1,400 = $2,600
Tom's Tax burden is $2,600 and Ray's Tax burden is $1,400
