Each of the three public goods enjoys a preference in one of 3 paired-wise votings. This is the paradox of voting, which makes the voting inconclusive, and the society's preference for a public good remains unknown.

Step by step solution

01

Meaning of  paradox of voting 

The paradox of voting implies a situation in which individuals in a society cannot rank their preferences so that the overall society's preference for the public good can be established. In such cases, paired choice majority voting does not give conclusive preference for any public good. This is explained in the next step.

02

Explanation of the paradox of voting in the given table

In the below table, Colbert, Fallon, and Kimmel are ranking three public goods (Courthouse, School, and Park) according to their preferences.


Ranking
Public good
Colbert
Fallon
Kimmel
Courthouse

1st Choice

The first look at the table does not show any dominant preference for any of the public goods. Thus, you will use paired-choice majority voting in which a first vote is held between any two of the three goods, and then the winner is compared with the left public good to see which one wins.

You will start by taking the pair of Courthouse and School and observing each individual's ranking. The public good, which will have a better ranking, will be preferred. For example, Colbert gives Courthouse a second choice and School a third choice; comparing these two, Colbert prefersCourthouse over School. Similarly, you can find this for others, as done below.

S.No
Election Pairs
Supporter
Outcome
1.Courthouse-School
Colbert and Fallon prefer Courthouse and Kimmel prefers School
Courthouse
2.School-Park
Fallon and Kimmel prefer School and Colbert prefers Park
School
3.Courthouse-Park
Fallon prefers Courthouse but Colbert and Kimmel prefer Park
Park

You can see that there is no overall majority for one particular public good. There is only a pairwise majority. For example, the Courthouse is preferred over School, and School is preferred over Park. This should mean that Courthouse should be preferred over Park as well, but this is not the case above. This is the paradox of voting, where ranking preferences can lead to irrational outcomes.

Consider a corrupt provincial government in which each housing inspector examines two newly built structures each week. All the builders in the province are unethical and want to increase their profits by using substandard construction materials, but they can’t do that unless they can bribe a housing inspector into approving a substandard building.

a. If bribes cost \(1,000 each, how much will a housing inspector make each year in bribes? (Assume that each inspector works 52 weeks a year and gets bribed for every house he or she inspects.)

b. There is a provincial construction supervisor who gets to hire all of the housing inspectors. He himself is corrupt and expects his housing inspectors to share their bribes with him. Suppose that 20 inspectors work for him and that each passes along half the bribes collected from builders. How much will the construction supervisor collect each year?

c. Corrupt officials may have an incentive to reduce the provision of government services to help line their own pockets. Suppose that the provincial construction supervisor decides to cut the total number of housing inspectors from 20 to 10 in order to decrease the supply of new housing permits. This decrease in the supply of permits raises the equilibrium bribe from \)1,000 to \(2,500. How much per year will the construction supervisor now receive if he is still getting half of all the bribes collected by the 10 inspectors? How much more is the construction supervisor getting now than when he had 20 inspectors working in part b? Will he personally be happy with the reduction in government services?

d. What would happen if reducing the number of inspectors from 20 to 10 only increased the equilibrium bribe from \)1,000 to $1,500? In this case, how much per year would the construction supervisor collect from his 10 inspectors? How much less is the construction supervisor getting than when he had 20 inspectors working in part b? In this case, will the construction supervisor be happy with the reduction in government services? Will he want to go back to using 20 inspectors?

We can apply voting paradoxes to the highway construction example of Table 5.2. Suppose there are only five people in a society, and each favors one of the five highway construction options listed in Table 5.2 (“No new construction” is one of the five options). Explain which of these highway options will be selected using a majority paired-choice vote. Will this option be the optimal size of the project from an economic perspective?

Does traditional one-person-one-vote (1p1v) majority voting allow voters to directly express differences in strengths of preference? Does quadratic voting do any better? Discuss the differences and then explain which system you prefer, and why.

Use the distinction between the characteristics of private goods and public goods to determine whether the following should be produced through the market system or provided by government: (a) French fries, (b) airport screening, (c) court systems, (d) mail delivery, and (e) medical care.
