Public Sector Finance & Economics Flashcards
What are the reasons for government intervention?
- market-pareto efficient
- market failures
- property rights
- enforcement of contracts
- merit goods
What are the four roles of Government
- allocative
- redistributive
- stabilisation
- regulatory
Explain the allocative role of government
- provision of goods and services that would not otherwise be provided by the market system
- problem: how much of the good to supply and what should the consumer pay?
- mention public goods, externalities, and monopolies
Explain the redistributive role of government
- the correction of the skewed distribution of income and wealth in an economy
- problem: difficult to measure utility from income
- efficiency cost?
Explain the stabilisation role of government.
- the successful attainment of macro-economic growth rate, low unemployment and stability of the price level
- modern government is held responsible by the electorate for the economy’s performance
- achieved through fiscal policy
- in a small, open economy it is very difficult for us to stabilise
Explain the regulatory role of government
- for the private market to work there needs to be an equitable arbitrator to define property rights and enforce contracts.
- if there were no property rights or contract enforcement there would be no incentive to work, save or invest.
- if government is weak, private enforcers emerge
What is pareto efficiency / optimum
a situation where it is no longer possible to make one person better off without making anyone else worse off
when can pareto efficiency be achieved
under certain restrictive assumptions through perfectly competitive markets
what is pareto improvement?
a situation where it is possible to make at least one person better off without making anyone else worse off
what is the impact of a market failure
it reduces efficiency and therefore welfare in an economy
What is a private good?
- excludable
- rival in consumption
what is a public good?
- non excludable
- non rival in consumption
what is the free rider problem
a person who receives the benefit of a good but avoids paying for it
why does the free rider problem occur?
- good is non excludable
- because people are not charged for their use of the public good, they have an incentive to free ride
what is a common resource?
- non excludable
- rival in consumption
what is the tragedy of the commons
- a parable that illustrates why common resources are used more than is desirable from the standpoint of society as a whole
e. g. why medieval sheep farmers really needed the enclosures
what are club / toll goods?
- excludable
- non rival in consumption
what are mistakes that people make when thinking about public goods
- they are not just any goods provided by the state
- not only provided by the state. they can be provided by the private sector or charities.
what might be the impact of technology on public goods?
it may become cheaper to exclude customers
How to ration public goods?
- tolls
- taxation
- queuing
- rationing
what does excludability mean?
the property whereby a person can be prevented from using a good
what does rival in consumption mean?
the property whereby one person’s use diminishes other people’s use of a good
What is the optimal provision of a public good?
0
why is 0 the optimal provision of a public good?
- public goods are non excludable and non rival in consumption
- the marginal cost of an extra person is 0
in terms of a public good, what is the difference between the marginal cost in production and consumption
- an additional person adds to the marginal cost in production but not consumption
what is an externality?
- the uncompensation impact of one person’s actions on the well-being of a bystander
- an example of a market failure
what is the social cost of a good? (externalities)
private costs of the producers
+ costs of those bystanders
= social cost
what does it mean to internalise the externality?
altering incentives so that people take account of the external effects of their actions
what is the definition of a positive externality?
an action of an individual or firm which confers benefits on others but for which the latter does not pay
what is the definition of a negative externality?
an action of an individual or firm which confers costs on others but for which the latter is not paid
what is the cost to society of a positive externality?
larger than the cost to the consumer(s)
what is the cost to society of a negative externality?
larger than the cost to the producer(s)
where is the social cost curve of a positive externality?
above the demand curve (takes into account the external benefits to society)
where is the social cost curve of a negative externality?
above the supply curve (takes into account the external costs imposed on society)
what quantity of a good with a positive externality should be produced?
where the supply curve crosses the social-cost curve
what quantity of a good with a negative externality shodl be produced?
where the demand curve crosses the social-cost curve
how is a positive externality internalised?
subsidy
how is a negative externality internalised?
taxation
what is the relationship between externalities and property rights?
the market fails to allocate resources efficiently because property rights are not well established
what is the Coase Theorem?
- the proposition that if private parties can bargain without cost over the allocation of resources, they can solve the problem of externalities on their own
- whatever the initial distribution of rights, the interested parties can reach a bargain in which everyone is better off and the outcome is efficient
what is the traditional way of looking at the reciprocal nature of externalities?
causes and fairness
what is the central question in terms of the reciprocal nature of externalities?
property rights
how does Coase look at the reciprocal nature of externalities?
efficiency
list 4 transaction costs
- identifying the parties with whom one has to bargain
- getting together with them
- actually bargaining with them
- observing and enforcing any bargain reached
what is the simple / Stigler version of the Coase Theorem?
if there are zero transaction costs, the efficient outcome will occur regardless of the choice of legal rule
what is the complex version of the Coase Theorem?
efficient laws and social institutions are the ones that place the burden of adjustment to externalities on those who can accomplish adjustment at least cost
what are some policy solutions to the externality problem
- regulation
- taxes
- subsidies
- marketable permits
- patents
what are the assumptions of the model of perfect competition?
- market participants have perfect information
- consumers know their preferences perfectly
- firms know the best available technology, the productivity of each worker, and the cheapest prices of all inputs
What is the impact of imperfect information?
inhibits prices and markets from performing its function of communicating important information about economic scarcity and coordinating production
in order to make an informed and optimal decision the economic agent must have perfect information. What is that.
information about the
- quality of the good
- price of the good
- future
what is the solution to imperfect information?
- usually regulation
- where information failure is chronic the state may opt to produce the good or for a social insurance scheme
What are the consequences of asymmetric information?
- adverse selection
- moral hazard
what is adverse selection?
occurs when there’s a lack of symmetric information prior to a deal between a buyer and a seller
Explain the principal and agent problem?
- bureaucrats and politicians act as agents of the electorate
When does the principal and agent problem lead to inefficiencies
when
- there is asymmetric information between the agent and principal
- the goals of the agent and principal differ
- there are costs to the principal observing the actions of the agent
what is moral hazard?
occurs when there is asymmetric information between two parties and change in behaviour in one party after a deal is struck
What are the benefits of competition over monopoly?
- static benefits
- dynamic benefits
- equity benefits
What are the static benefits of competition over monopoly?
more output at lower price (eliminates deadweight loss)
What are the dynamic benefits of competition over monopoly?
- makes forms more efficient
- selection process - good firms grow, poor firms exit
- stimulates innovation
What are the equity benefits of competition over monopoly?
- small firms are protection from abuse of monopoly power
- monopoly profits dkew distribution of wealth in society
What monopoly actions can firms take
- collective anti-competitive behaviour
- single firm behaviour
name the three areas of a natural monopoly that are regulated?
- pricing
- access
- quality of service
give an important fact in terms of the regulation of professions
the profession should never be in the majority when it comes to regulation
what is government failure?
where activities of the State fail to promote efficiency
what are the two main sources of government failure?
- the procedures of a democratic system can lead to a pareto inefficient outcome
- the actions of the State are usually executed by a intermediary
What is the ethical voter model
voting involves some level of altruism
what is the median voter theorem
with single-peaked preferences the key to success is attracting the median voter
What does Arrow’s impossibility theorem say?
cannot express the will of the people through voting system
Under Arrow’s impossibility theorem, no voting system exists that satisfies …
- transitivity
- non dictatorial choice
- independence of irrelevant alternatives
- unrestricted domain
What may the goals of the bureaucracy be?
- salary
- power
- personal presitige
- size of department
- increased budget
