Suppose a government is considering implementing three projects in a community, a public park, a draught relieve scheme and a shopping mall. There are three voters; Thereza, Vicky and Marces. The voters' benefits for each project are shown below.

Thereza

Public Park =-5

Draught relieve scheme= -1

Marces =20

Vicky

Public Park = 10

Draught relieve scheme= -2

Shopping mall = -3

Marces

Public Park= -6

Draught relieve scheme =20

Shopping mall= -5

(a) Explain what would happen if the projects where voted each one at a time.

(b) What will be the potential gains to the three voters if all projects are implemented?

(c) Do you think there is potential for logrolling in the voting of these projects? If there is, how will it affect the outcome of the votes?
