economics 1b - Resource Allocation and Government Intervention

relative price

is seen as the price of any one good or service measured in terms of the price of another good or service.

Relative prices send clear signals to producers and consumers and therefore direct resources to their highest end use.

in sac: firms use supply and demand to determine what to produce. so relative rpices determine resource allocation in a market capitalist economy as if the price of one good increases relative to the price of another, this sends price signals to firms, showing an increase in demand and they will allocate more resources to that product.

for example: The price of matcha relative to its substitutes has increased, resulting in firms allocating more resources to its production due to profit motive (firms aim to maximise profits) as it has become relatively more profitable. For example, the increase in the price of matcha tea relative to the price of green tea encourages producers to allocate more resources to the production of matcha tea and away from green tea.

relative price change

is a change in the price of one good compared to the price of another good.

It shows the opportunity cost of one good in terms of another.

resource allocation

is the study of how the factors of production (l,l,c) are directed towards the production of goods and services to meet the needs of households, businesses, governments and other economic agents.

how relative prices determine resource allocation (3 economic q’)

economists will use 3 questions to determine resource allocation with relative prices: what, how and who.

WHAT? (1/3 economic q’s)

Economists are interested in ‘What’ goods are produced. they wanna know where resources are being directed in terms of production. e.g., we may want to ask the following sorts of questions:

• Why is Australia using its labour resources to produce mineral exports rather than to manufacture cars?

• Why have some of our scarce resources been moved from mining to more service-based industries in recent years

• What will happen to the allocation of resources as the earth’s climate systems become increasingly disrupted?

HOW? (2/3 economic q’s)

refers to ‘How’ resources are being used in the production process. its assumed that self-interested firms will try to minimise their costs of production and offer the best product they can, meaning that they seek the most efficient way to convert their land, labour and capital into the end product. We might consider the following:

• How will scarce resources be allocated in response to perceived changes in labour market conditions in the future?

• How will the invention of more sophisticated artificial intelligence affect the mix of labour and capital in the production process?

• How can community pressure and the buying decisions of consumers influence the methods of production employed by firms in a country?

WHO? (3/3 eco q’s)

how the products are made and ultimately distributed in the economy - or ‘who’ gets to enjoy those g/s produced. in a purely market capitalist economy, markets will typically allocate resources to those who are willing and able to pay. given that no economy in the world is completely market capitalist, it is not surprising that the predictions that may be made by our model may not eventuate.

• But in a country e.g. Australia, the market mechanism is a very useful model that can provide consumers, businesses and other economic observers with the capacity to predict changes in prices and quantities (as well as explain retrospectively why these parameters may have changed). With respect to this question we may consider:

• What influences the wages paid to different professions?

• How does the scarcity of labour affect the allocation of the world’s scarce resources?

• How do the buying decisions of the very wealthy affect the ability of low-income earners to access necessities?

how does the market system allocates resources using the price mechanism?

Markets show preferences as consumers spend to maximise wellbeing, guiding scarce resource allocation

. Prices, set by demand and supply, ration resources efficiently. Market interconnections mean changes affect substitutes, complements, labour, and financial markets.

Relative prices signal opportunity costs and profit potential—for example, 2022 oil price rises boosted EV demand, raising their relative price and production.

what is the price mechanism?

The price mechanism explains how demand and supply determine relative prices and allocate resources. It influences:

• What to produce – resources flow to high-demand, profitable goods.

• How to produce – firms substitute between labour and capital based on relative costs (e.g. self-serve checkouts when wages rise).

• For whom to produce – goods go to those with the willingness and ability to pay, often favouring higher-income earners.

While markets produce profitable goods, governments may intervene to correct market failure or improve equity where income distribution leads to inequality (e.g. housing affordability issues).

KK15 - role of free and competitive markets in promoting an efficient allocation of resources and improved living standards

characteristics of a competitive market

the market structure that forms the basis of demand and supply analysis.

• Many buyers and sellers: no individual has market power → price takers, not price makers.

• Homogeneous products: identical goods, easily substitutable → firms compete mainly on price.

• ease of entry/exit: low setup costs allow new firms to enter if abnormal profits exist.

Other assumptions

• Full information: buyers and sellers can easily compare prices and make informed choices.

• Resource mobility: resources move to industries with the greatest benefit.

• Self-interest: sellers maximise profit, consumers maximise utility (satisfaction).

the concept of efficient allocation of resources

• Allocative efficiency: when the combination of goods and services produced and consumed gives the highest collective satisfaction for society.

  It occurs when the right goods are produced and allocated to those who value them most.

  In a free market, price signals, resource mobility, and ease of entry/exit cause resources to move from low-profit to high-profit areas, reflecting consumer demand.

  Consumers’ buying decisions determine resource allocation, as higher demand raises prices and attracts more producers.

  Example: higher demand for puppies raises prices → producers reallocate resources to produce more puppies.

  Allocative efficiency is less likely in monopolies or oligopolies, where barriers to entry and limited competition keep prices higher and reduce collective satisfaction.

how efficient allocation of resources improves living standards

• Efficient allocation of resources improves living standards because scarce resources (land, labour and capital) are used in ways that maximise the production of goods and services, increasing the quantity, quality and affordability of products available to consumers.

how allocative efficiency improves living standards

• Allocative efficiency improves living standards because resources are directed toward producing the goods and services that consumers most prefer. This means society’s limited resources are used to satisfy the greatest number of wants, increasing consumer satisfaction and overall wellbeing.

how productive efficiency improves living standards

• Productive efficiency improves living standards because goods and services are produced at the lowest possible cost using the least amount of resources. This reduces waste and allows businesses to produce more output, which can lead to lower prices, increased real incomes and greater access to goods and services.

how dynamic efficiency improves living standards

• Dynamic efficiency improves living standards because businesses invest in research, development and new technology over time. This leads to innovation, improved production processes, higher productivity, better quality goods and a greater variety of products, which supports long-term economic growth.

how intertemporal efficiency improves living standards

• Intertemporal efficiency improves living standards because resources are allocated in a way that balances present consumption with future needs. This encourages saving, investment and sustainable use of resources so that future generations can also enjoy high levels of income, production and wellbeing.

define competition

the rivalry among sellers (firms) trying to maximize profits, market share, or sales by offering the best value, such as lower prices, better quality, or superior service to consumers

KK16-18 - MARKET FAILURE

define market failure

occurs when an unregulated market (ie. one relying on the operation of markets without government intervention) results in an allocation of resources that is inefficient in the sense that living standards or welfare is not maximised.

Public goods

Private goods: rivalrous (depletable) and excludable — consumption by one person reduces availability for others, and people must pay to consume (e.g. a smoothie).

Public goods: non-rivalrous (non-depletable) and non-excludable — one person’s use does not reduce availability, and people cannot easily be prevented from using them.

Examples of public goods: lighthouses, street lights, national defence, police, border control, prisons, free-to-air radio.

Public goods create the free rider problem, where people benefit without paying.

Because producers cannot charge all users, they may avoid producing these goods, leading to an under-allocation of resources and allocative inefficiency.

government intervention: public goods

1. Subsidies to private producers

• Government funds firms to cover costs + opportunity costs.

• Can be:

  • Direct cash payments

  • Low/no interest loans

  • Tax concessions

  • Grants

• Allows the good to be provided free to the public.

• Example: Private companies provide street lighting but are funded by government.

2. Direct government provision

• Government becomes the producer of the public good.

• Employs labour and capital directly.

• Examples:

  • Defence

  • Lighthouses

  • Emergency services

• Reallocates resources to achieve allocative efficiency and improve societal wellbeing.

Exception

• Some goods with public good characteristics (e.g. free-to-air TV) are funded through advertising, meaning the market sometimes finds its own solution.

what are externalities?

• Externalities occur when a third party is affected by a producer–consumer transaction and can be positive or negative, during production or consumption.

  They create a mismatch between private and social costs or benefits.

government intervention: positive externalities

• Positive production externalities: firms underproduce because social benefits exceed private benefits (e.g., R&D, business training, beekeeping).

• Positive consumption externalities: goods are underconsumed because society benefits more than the consumer pays for (e.g., vaccinations, education). - NOT EVEYRONE CONSUMES THEM BUT THYE SHOULD BE AS THEY HELP EVERYONE THEREORE INEFFICIENT TOOO FEW REWOURCES ALLOCATED TO THEM

• for example: This is a market failure, as products such as matcha produce a positive externality, such as health benefits in the consumption, and often have an underallocation of resources towards them than what would be optimal.

• To increase allocative efficiency the government therefore intervenes in select markets to promote greater production and consumption of certain goods and services.

government intervention: positive externalities

• Forms of government intervention include: government regulations (eg legal requirement for schooling), advertising (STI check up ads), subsidies and direct provision (healthcare and education)

negative externalities

• Negative production externalities occur when production activities impose costs on society that are not factored into the cost of production. A common example is pollution

• Negative consumption externalities occur when activities undertaken impose costs on third parties. An example is the consumption of cigarettes in public

• Common forms of government regulation to address this market failure include: government regulation (illegal to sell illicit drugs), indirect taxation – tax on producer or intermediary (excise on petrol), subsidies for substitutes (eg solar panels), government advertising (gambling)

government intervention: negative externalities

assymmetric information

• occurs when one party in a transaction has more information than the other, violating the assumption of perfect information in perfectly competitive markets and leading to inefficient resource allocation

  Often the seller has more information about product quality or reliability (e.g. used cars, mechanics, vitamins, dentists), giving them greater bargaining power.

  Sometimes the buyer has more information, usually about themselves, which affects the transaction (e.g. personal insurance).

responses to asymmetric information

• Moral hazard occurs when people change their behaviour to one less efficient in response to a transaction. For example people with car insurance may be less vigilant in preventing theft. This causes an over allocation of resources to certain areas.

• Market responses to asymmetric information include: businesses screening potential employees, independent product reviews, the internet (pricing).

• Government responses to asymmetric information include: consumer law, regulations about product disclosure (food ingredients), advertising, subsidies.

common access resources

• Common access resources are not owned by anyone, usually have no market price, and are available to anyone without payment. They are non-excludable but rivalrous in consumption.

  • Examples include fish in the ocean, clean air, and forests.

  • Garrett Hardin described the issue as the “tragedy of the commons” in 1968: individuals acting in their self-interest to maximise profit or utility overuse the resource, leading to its depletion or destruction.

government intervention: common access resources

• Because common access resources are non-excludable and have no price, they tend to be overproduced and overconsumed, leading to depletion.

  Governments may intervene to reduce use, for example by:

  • Banning harmful products (e.g. CFCs)

  • Mandating cleaner technology (e.g. catalytic converters)

  • Restricting access times (e.g. duck hunting seasons)

  • Protecting land (e.g. national parks)

  For climate change, governments have used carbon taxes and renewable energy subsidies, which improve intertemporal efficiency by changing relative prices.

how government failure effects efficiency

Government Failure (General Evaluation)

• May misallocate resources due to poor policy design or political bias.

• Administrative and enforcement costs reduce productive efficiency.

• Governments may lack accurate information about socially optimal output.

define indirect taxation

Tax on producers or intermediaries to reduce negative externalities and correct market failure.

how indirect taxation affects efficiency

Indirect Taxation

• Internalises external costs → improves allocative efficiency.

• Raises revenue to fund public goods.

• Higher production costs may reduce productive efficiency.

• Lower profits may reduce investment → lower dynamic efficiency.

subsidies

Government financial support to encourage production or consumption of goods with positive externaliti

how subsidies affect efficiency?

Subsidies

• Encourages production/consumption of goods with positive externalities → improves allocative efficiency.

• Can improve intertemporal efficiency (e.g. renewable energy).

• Opportunity cost of government spending.

• Risk of over-allocation and reduced cost-minimisation → productive inefficiency.

regulations

Government rules or laws that control production or consumption to reduce negative externalities or protect resources.

how regualtions affect efficiency?

Regulation

• Directly reduces overproduction/overconsumption.

• Can improve allocative efficiency if well enforced.

• Compliance costs increase business expenses.

• May reduce dynamic efficiency if innovation is discouraged.

advertising

Government-funded information campaigns to reduce asymmetric information or encourage socially beneficial behaviour.

how advertising affect efficiency?

Advertising / Information Campaigns

• Reduces asymmetric information → improves allocative efficiency.

• Relatively low cost compared to taxes or regulation.

• May be ineffective if behaviour is addictive or unresponsive to information.

direct provision

Government directly produces a good or service to ensure under-provided public goods are available.

how how direct provision affect efficiency?

Direct Provision

• Ensures provision of public goods → corrects under-allocation.

• Can improve equity and living standards.

• Lack of profit motive may reduce productive efficiency.

• Political influence may distort resource allocation.

define market failure

a situation where the forces of demand and supply are unable to allocate resources efficiently, or where resources are allocated in such a way where the national living standards or welfare isn’t maximised.

types of market failure

• externalities

• public goods

• common access resources

• assymmetric info

types of government intervention

• subsidies

• indiret taxes

• regulation

• direct provision

• advertising

government failure**

a situation where the government intervention fails to improve the allocation of resources or makes it worse.
