A subsidy, on a graph...

Marginal social benefit (MSB)

marginal private benefit (MB) + marginal external benefit

Marginal social cost (MSC)

marginal private cost (MC) + marginal external cost.

All businesses should hire more when...

marginal revenue product is greater than the wage rate.

Because of free rider problem...

markets underproduce products with positive externalities.

game theory

mathematical tool for understanding how players make decisions, taking into account what they expect other players to do.

Regulated private monopoly.

Markets overproduce ___ and underproduce ___

products with negative externalities, products with positive externalities.

public goods

provide external benefits consumed by everyone, no one can be excluded.

Two major government policies to deal with natural monopoly

public ownership and regulation

crown corporations

publicly owned businesses in Canada, created by government.

Key insight of game theory

tension between the nash equilbrium outcome and the better outcome.

Public goods are likely to be under provided in...

the absence of government

With positive externalities...

the market clearing price is too high for buyers to be willing to buy the socially best quantity of output, and too low for sellers to be willing to supply the socially best quantity.

the overuse and depletion of a resource that no one can be excluded from because of missing property rights.

Subsidies remove...

the wedge that positive externalities drive between prices for buyers and sellers, getting individuals and businesses to voluntarily choose the quantity of output best for society.

Challenge facing government policy makers

to gain the low cost efficiencies of economies of scale but avoid the inefficiencies of monopoly's restricted output and higher price.

Internalize the externality:

transform external costs into costs the producer must pay to the government

Rule for smart social choices

Choose the quantity of output where —> marginal social cost (MSC) = marginal social benefit (MSB)

Major forms of government regulation in Canada

Government departments, agencies and boards, professional associations

When is public provision used?

Governments provide products or services when the positive externalities are widespread and important for citizens, and/or when it is difficult to collect revenues from users.

Costs associated with natural monopoly?

High fixed costs and low marginal costs --> results in economies of scale.

In light of the competition act, how are mergers approved?

If mergers that reduce competition also produce economies of scale they may be approved for promoting "efficiency and adaptability"

Why do governments use rate of return regulation?

In principle, government regulators try to set a price that just earns normal profits. But its hard to to tell how hard a business is trying to keep prices low, so rate of return regulation is used.

Disadvantages of crown corporations

Lack of competitive pressure, incentives for reducing cost and increasing efficiency are small, bureaucratic.

Cap and trade system

Limits the quantity of emissions businesses can release into the environment//set quantities while the market adjusts price.

What does poverty result from?

Not owning labour skills or assets that the market values, or from not getting a high enough price for what you do own.

What happens to present value when interest rates rise?

Present value decreases when interest rates rise.

OPEC cartel

Since the recession of​ 1981-1983, the OPEC cartel has swung between periods of trust and high oil​ prices, and periods of​ mistrust, cheating, and lower oil prices. Just as game theory​ predicts!

Why is a subsidy often used by government?

To correct the problem of underproduction caused by positive externalities.

cartel

an association of suppliers formed to maintain high prices and restrict competition. Cartels collude to raise prices and restrict output to increase economic profits. Unstable because members can raise own profits by cheating others.

Trade offs to deal with market failure involve

evaluating whether the government outcome is better or worse than the market failure outcome

Income is a

flow-- an amount per unit of time

Emissions taxes internalize the externality by...

forcing producers to pay the external cost of the negative externalities; best policy choice.

Primary objection to cap and trade

give businesses a 'licence to pollute'

Primary advantage of cap and trade

gives businesses a choice between reducing emissions or buying permits to pollute.

Public provision

government provision of products or services with positive externalities, financed by tax revenues

Capture view of government regulation

government regulation benefits regulated businesses, not the public interest.

Public interest view of government regulation

government regulation eliminates waste, achieves efficiency, promotes the public interest.

Rule that yields maximum profits for a business

hire additional hours of labour​ (or any​ input) as long as marginal revenue product is greater than the wage​ (or price of the​ input).

Simple recipe for hiring inputs

hire additional inputs when marginal revenue product is greater than marginal cost

economic rent

income paid to any income in relatively inelastic supply

human capital: increased earning potential from work experience, on the job training, education.

increased earning potential from work experience, on the job training, education.

Externalities can be​ corrected, and the market outcome will be the same as the socially best outcome if...

individuals are faced with the private and external costs of their actions when making decisions.

market outcome

intersection of the MC and MB curves

Income = wages, input =

labour

Most important concepts determining each income are

labour -- marginal revenue product, capital -- present value, land -- economic rent.

Income = rent, input =

land

present value

amount that, if invested today, will grow as large as the future amount, taking into account earned interest.

Income = profits (normal and economic), input =

entrepreneurship

Two viewpoints about market outcomes and market failure.

(1) Market outcome, even with monopoly power, is better than government regulation outcome if significant government failure. (2) Government outcome, with public interest regulations, is better than market outcome if significant market failure.

When do externalities occur?

When clear property rights are missing.

What happens re: incentives when governments tax?

When governments tax, it reduces incentives to provide inputs and to produce outputs. This means that output markets will produce fewer products and services.

When do natural monopolies arise?

When the technology has economies of scale that require a single supplier.

When do markets fail?

When there are positive externalities and the government is absent.

emissions tax

a tax to pay for external costs of emissions

Marginal product

additional output from hiring one more unit of labour

marginal revenue product

Diminishing marginal productivity

as you add more of a variable input to fixed inputs, the marginal product of the variable input eventually diminishes.

benefits to society from a private choice
