Response to ECON100 Mock Test 3 Question 6. LUMS/M Schonger/G Johnes
Multi-peak
Order: Labour, Greens, Lib Dem, Conservatives
As you move away from Humphrey's most preferred party (Green), the next party is less preferred; so it is single-peaked.
As you move away from Jim's most preferred party (Labour), the next party (Green) is less preferred. As you move from the Green party to the Lib Dem party, the preferrence for the current party increases (i.e. Lib Dems are preferred to Greens). Hence Jim's preferences are multi-peaked in this ordering.
As you move away from Bernard's most preferred party (Conservatives) the next party(Lib Dem) is less preffered but the party after that is preffered more than the Lib Dems, so this ordering also makes Bernard's preferences multi-peaked.
Single-peak
| Labour | Lib Dem | Green | Conservative | |
|---|---|---|---|---|
| Humphrey | Third choice | Second choice | First choice | Last choice |
| Jim | First choice | Second choice | Third choice | Last choice |
| Bernard | Last choice | Second choice | Third choice | First choice |
In this scenario the order has changed: the Lib Dems and Green parties have swapped positions. As you move from each persons' peak the preference for the next party is less than the previous one, therefore each persons' preferences are single-peaked in this ordering.
