Unit 22 Flashcards
Whats this unit about
How we can model what governments do from an economic perspective.
The coercive power of government, obligation to citizens based on civil and human rights.
Define a government
only body in a geographical territory that can use force and threat of force on citizens of the nation.
Possible objectives of the government
- ensure mutual gains possible through economic interactions are as large as possible and fully realised
- Sharing these gains in a fair manners
Government policies examples
- competition policies to reduce price setting power of monopolies
- Environmental policies to reduce emissions of pollutants
- Subsidies for R&D
Government tools:
- incentives
- Regulation
- Persuasion or information
- Public provision
Government as a solution and problem
- to accomplish these valuable policies must have extraordinary powers - but this can also create a dilemma
Constraining government power:
- democratic elections
- institutional checks and balances
Market and government failure links
- market failure limited by the economic accountability due to demand curve of consumers
- Government failure limited by the political accountability of election defeat
Government as a monopolist/ dictatorship political rent
Gap between t2/t1 and C is a political rent. Lower tax revenue will give them higher future duration of his time in office.
What is an isorent curve
combinations of total tac revenue and future duration which give them same level of utility along the curve
- will choose highest isorent curve.
- Political rent = (T-C)xD
Changes to the curve with political competition
Now there is a governing elite and elections.
- Makes duration curve a little bit shallower - for any given level of tax revenue, stay in power for less time than in a dictatorship.
Income and substitution effect after political competition included onto diagram
- first shift the old curve parallel until it is tangential to the new isorent curve
- gap between durations and taxations are the income effect
- go from new income effect point to the actual outcome - to find substitution effect
- substitution effect here is positive as it moves us back to D*, the old duration rate.
What if duration curve is very shallow
as seen above, when duration curve is shallower due to more competition, low enough tax can lead to proportionally larger increase in duration = higher political rent
Democracy:
Political institutions of a country are rules of the game that determine who has power and how it is exercised
- who makes up the government
- The powers they can use when governing
Median voter model
Spectrum from left to centre to right
- assumption is uniform distribution across the spectrum.
- If we can just get everyone to the left/right of the opposing party, will end up both in the middle as they try to outcompete each other slowly
- Middle is a Nash equilibrium outcome
