Markets and Market Failure Flashcards
What are assumptions in economics?
Assumptions are initial conditions made before a micro or macroeconomic analysis is built.
Sometimes assumptions are used for simplification
Assumptions can be used to isolate the effects of a change in one variable on another.
Many assumptions are criticised for being unrealistic
What is the ceteris paribus assumption?
To simplify analysis, economists isolate the relationship between two variables by assuming ceteris paribus -i.e. all other influencing factors are held constant.
What is a positive statement?
Positive statement are objective statements that can be tested, amended or rejected by referring to the evidence.
(Objective and testable theories)
What is an example of a positive statement?
The falling price of crude oil on world markets will lead to a fall in demand for fuel efficient cars.
What is a normative statement?
Normative statements are subjective statements -i.e. they carry one or more value judgments about what ought to be.
(Value judgement and opinions)
What is an example of a normative statement?
A sugar tax is the best policy to cut obesity
What is positive economics?
Positive economics deals with objective explanation and the testing and rejection of theories.
What are the four economic resources?
Land
Labour
Capital
Enterprise
What is land as a economic resource?
The stock of natural (environmental) factor resources available for production.
What is enterprise as a economic resource?
Entrepreneurs organise the factors of production and also take risks
What is labour as a economic resource?
The quantity and quality of the human input into the production process.
What does capital refer to as a economic resource?
Man-made goods used to supply other products, e.g. technology, factories, machinery and software.
What are capital goods?
Goods that are used to make consumer goods and services.
What are examples of capital goods?
Factories Offices Machines Printing press Combine harvester Assembly line
What are Free Goods?
A free good has zero opportunity cost in its supply.
What are non-renewable resources?
Non-renewable resources are finite in supply.
Examples are crude oil, coal, natural gas and other fossil fuels, no mechanisms exist at present to replenish them.
The rate of extraction of finite resources depends in part on the current market price
What are renewable resources?
Renewables resources are resources that are replaceable if the rate of extraction is less than the natural rate at which a resource renews.
Examples of renewable resources are solar energy, tidal power, oxygen, biomass, fish stocks and forestry.
What is opportunity cost?
Opportunity cost measures the cost of a choice expressed in terms of the next best alternative foregone or sacrificed.
What are examples of opportunity costs? (READ)
Work leisure choices: The opportunity cost of deciding not to work an extra ten hours a week is the lost wages given up.
The opportunity cost of the government spending an extra £10 billion on investment in the NHS might be that £10 billion less is available for spending on education or defence equipment.
Why would you ration scarce resources?
Rationing is one way of allocating scarce goods and services when market demand exceeds available supply.
What are examples of rationing?
Health rationing occurs when demand for health care services outstrips the available resources leading to waiting lists and delay for health treatments.
Cash rationing in Indian banks when the government in 2016 took larger denominations of bank notes out of circulation in a bid to reduce corruption.
Ticket rationing by clubs when demand for tickets for a big match exceeds capacity of a stadium.
What are different ways to ration scarce resources?
By market price
By consumer income
By assessment of people’s need
By household postcode
By education level
By age
By gender
By nationality.
Why has Food bank use grown rapidly in recent years?
Higher food prices have made food less affordable for low income households
High long term unemployment have hit family budgets
Declining real incomes for many people on lower wages
Welfare reforms including a a maximum welfare cap for families and tighter rules for claiming benefits.
More food banks have been set- i.e. supply is responding to growing demand and need among many families.
What is a PPF?
A PPF shows the maximum potential output combinations of two goods an economy can achieve when all its resources are fully and efficiently employed.
