Democratic Economy Flashcards
What is the spatial theory of elections?
There is a single dimension policy space and each voter has a unique most preferred point. Voters therefore select the party whose policy is closest to their own point
What are single peaked preferences?
Each person has an ideal choice and outcomes further from this point are preferred less.
X is between Y and the preference.
What are Euclidean preferences?
Proximity preferences, so whichever preference is closer in either direction
Using Euclidean preferences what can we assume about the outcome of elections?
If X is selected it was closer to more peoples preferred points. e.g Wins the median voter
Using single peaked assumptions what can we say about the Median voter theorem?
The median voter’s most-preferred point is
preferred by a majority to any other point y
What are some assumptions for basic median voter models?
- 2 parties with policy commitments
- The voter knows the policies
- Voter selected the party whose policy they prefer
What did Downs (1957) say about median voter theorem in relation to assumptions about each parties position?
- Parties want to win the election
- Parties don’t otherwise care for policy
- Parties are free to locate anywhere in the policy space
- Knows voters preferences/position of the median voter
Why if you add additional parties into the median voter model does it become problematic?
There will be a permanent disequilibrium as placing yourself at the median voter doesn’t guarantee an electoral win. Parties will shift around in search of winning position
Why does median voter model become problematic with multi issue voting?
Every point has a non empty win-set. There is no equilibrium. (Venn diagram)
Adams (2004) main conclusion?
That parties shift position only when the public opinion shifts away for their policy position
What did Adams (2004) examine?
Whether parties change policy/ideologies in response to public opinion or past election results
What did Adams (2004) conclude about the role of previous elections?
No significance to the results- no link between parties changing ideologies and past electoral results
What is the comparative manifesto project?
Examine the content of parties policy proposals (manifestos) and analyse their evolution over time.
What do spatial modellers (Downs 1957) assume?
That parties aim to maximise votes. The aim is a position that means no party can improve vote share by moving position, given the policies of their rivals
What does Budge tell us about parties ideologies?
The ideologies of the parties have a substantial amount of ‘temporal stability’ perhaps due to how they cannot forecast how this will affect them in the election
