Incumbent politician: politician holding or acting in office of president before the election, whether seeking re-election or not
Challenger politician: politician currently against the incumbent politician- working towards gaining the hold in office
Voter: individuals who will vote upon whether the incumbent or challenger will hold the office
Term 1: the incumbent chooses a level of effort (or e1), which determines the probability of a good outcome
Election: voter observes policy and chooses whether to retain or replace the incumbent
Term 2: The incumbent (or the challenger if the incumbent was replaced) chooses a level of effort (or e2), which results in a policy outcome
High quality politicians: they will get a good outcome regardless of effort
Low quality politicians: they will pay e2 for effort to gain a good outcomes
In term 2, how much effort will the politician exert?
Will the voter retain or replace the incumbent?
In term 1, how much effort will the politician exert?
The voter should compare two probabilities:
Probability that the incumbent is high quality
Probability the challenger is high quality (p by assumption)
The voter should replace the incumbent if the outcome is bad, and keep the incumbent if the outcome is good
Voters use the media to gain information.
Media can highlight successes and failures of incumbent politicians (make π larger)
With media coverage, incumbents are more motivated to be responsive to voters
Participate in more committee hearings
Vote as individuals (not in lockstep with their party)
Secure more federal funding for their district
Challengers have obvious incentives to points out failures of the incumbent policies (make π larger)
The threat of a challenger should motivate incumbents to be more responsive to voters.
changes to the external environment of congress (shifts in social, economic, electoral environments reduce the incentive for bipartisanship)
changes to the internal environment (changes in the formal and informal institutions of congress have evolved in ways that exacerbate partisan conflict)
it is likely a mix of both
vote can be instrumental because it changes the outcome
vote can be “voice” - it influences the margin of victory but not the outcome
voters probably do not vote due to a desire to influence the election outcome
in pairwise contests, you always want to vote sincerely, if you vote at all, as there is no incentive to vote strategically
Condorcet paradox (collective preferences can be cyclic, even if the preferences of individual voters are not cyclic)
if you can control the agenda, you can manipulate outcomes
Polarization creates meaningful policy differences to the voters
Centrists, undifferentiated parties do not represent the diversity of interests of contemporary American society
Government policy jumps from one extreme to another
.Polarized parties prevent compromise, the type required by democratic politics in heterogeneous societies
if parties can discipline their members perfectly, then policy making becomes “the interaction of parties”
a polarization party median can then overpower the influence of he median voter in the whole legislature
There is a decline in legislative productivity, and decline worsens with super majoritarian obstacles.
i.e the filibuster if the filibuster pivot in part of the majority party
consider pivotal politics model and the size of gridlock interval
The status quo: jury determines innocent or guilty; if guilty judge determines the punishment
The Roman system: start with a serious punishment and worked down the list
Mandatory sentencing: each crime has a predetermined sentence
Single-member district: an election were only one politician represents a District
Plurality rule: an election where the candidate with the most votes wins
Strategic voting: innocence, citizens do not wanna waste their vote. This requires voting for a less preferred candidate who is stronger or more likely to win
Strategic entry: politicians or parties should withdraw if they believe their efforts and resources will be wasted
General election: most states allocate electoral votes to plurality winner
Primary: most states allocate delegates to plurality winner
It may reduce polarization
Majority rule man rich public debate. It encourages consideration of a larger group of potential candidates.
Primary: the parties decide the electoral rule for primary elections
Electoral college: individual states could pass laws to change the electoral college system from plurality rule to majority rule
