IGCSE EDEXCEL ECONOMICS FULL Flashcards
What is the Basic Economic Problem?
Unlimited Wants
Finite Resources
What are Needs?
The Basic Requirements needed for Human Survival
What Economic Decisions have to be made when overcoming the basic economic problem?
What to produce
How to Produce
For Whom to Produce
What is Opportunity Cost?
The next best alternative forgone
What are Scarce Resources?
Amount of resources available when supply is limited
What is Distributiuon?
Act of sharing things among a large group of people in a planned way
What are Choices?
Deciding between alternative uses of scarce resources
what is expenditure?
spending by a government
What graph illustrates the idea of opportunity cost?
PPC diagram
Why is it never possible to operate outside of the PPC diagram?
The country/government/firm does not have the resources to produce that amount of goods.
Why might Economic Growth occur?
New Technology –> Increases productive potential. Usually Faster and more reliable in production and therefore more output can be produced
Improved Efficiency –> Over time resources are used more efficently. These more efficent methods replace the old ones and more outputs can be produced with fewer resources
Education and Training –> A country’s economy becomes more productive as the proportion of educated workers increases. Educated workers can work more efficently on tasks that require skills. However a country has to find the right balance between academic and vocational education
New Resources –> New Resources more Productive –> Increases Production.
When Might the PPC fall inwards?
Negative Economic Growth
. Country runs out of Natural Resources
. Productive Potential reduced by weather patterns
. If highly skilled workers move overseas
. Wars, Conflicts and Natural Disasters
What are Capital Goods?
Capital Goods –> those purchased by firms and used to produce other goods such as factories, machinery, tools and equipment
What are Consumer Goods?
Consumer Goods –> those purchased by households such as food, confectionery, cars, tablets and furniture
What is PPC diagram?
A line that shows the different combinations of two goods an economy can produce if all resources are used up
What is Revenue?
Money that a business receives over a period of time, especially from selling goods or services
What are the Reasons Consumers may not always Maximise Benefit?
. Consumers may have difficulty in calculating the benefits from consuming a product. (Measuring Sactisfactory gained is very difficult)
. Some consumers develop buying habits that may affect their ability to make rational choices. (Some people stay loyal to a particular brand)
. Some people are influenced by the behaviour of others (children may purchase the same brands as their parents as they trust that their parents or they are familiar with the brand)
Reasons why Producers may not always Maximise their Benefits?
.Some Producers have alternative business objectives. Although profit may be important to them, other issues may also be important. (Producing high quality goods, or increasing the quality of customer service requires higher costs and therefore lower profits)
. Some Commericals are Non-Profit Organisations
.An increasing minority of businesses are being set up as social enterprises. These are organisations that operate commercially but aim to maximise improvements in human or environemntal well-being
What will prevent Consumers and Producers from maximising their businesses?
If they do not have access to all the information available. For example, if a consumer does not know that a particular product can be purchased at a lower price in another location they wont maximise their benefit
What is Demand?
The Amount of a good that will be bought at a given price over a period of time.
What is Effective Demand?
How much would be bought (that is, how much people can afford to buy and would actually buy) at any given price.
What is the relationship between Demand and Price?
Inverse Relationship
As Price Increases Demand Decreases
As Price Decreases Demand Increases
What is the Shift in Demand Curve?
Movement to the left or right of the entire demand curve when there is a change in any factor affecting demand except for the price
What factors May Shift Demand?
Advertising Income Demographic Changes Price of Complements (Some goods are bought together (complementary goods) so if the price of one increases the demand for both will decrease) Price of Substitutes Fashion and Tastes (New Trends)
When There is an Increase in Income what happens to the Demand?
Generally, when Disposable Income rises, demand for goods will also rise. For example, if someone has an increased income they will have more disposable income to buy a car. These are Normal Goods (Goods where when Incomes Rise Demand also Rises)
However, a minority of goods are inferior goods. this means that the quantity demanded will actually fall when incomes rise. For Example, consumers who generally buy a relatively cheap supermarket brand of baked beans may switch to a more expensive brand when Incomes Rise
What Are Normal Goods?
Goods for which demand will increase if income increases or fall if income falls
What are Inferior Goods?
Goods for which demand will fall if income rises or rise if incomes fall
What is Disposable Income?
Income that is available to someone over a period of time to spend; it includes state benefits but excludes direct taxes
How do Demographic Changes affect Demand?
.Age Distribution of Population –> if people in UK are prdominantly older than goods for children decrease in demand
.Gender Population (If there are more men than women in a population there would be a decrease in demand for female goods)
. Geographical Distribution may change demand (In more developed countries more and more people live in urban area. As a result, demand for schools and hospitals in urban areas will be higher than in rural areas)
.Many Countries with large ethnic groups will demand products that are associated with their culture. In Australia, there is a large Southeastern Population. This has resulted in spread of restaurants offering, vietnamese, Thai food Etc:
What is Supply?
The amount of a good that sellers are prepared to offer for a sale at any given price over a period of time.
What is the relationship between Supply and Price?
When Price goes up Supply also goes up
When Price goes down Supply also goes down
Why is there a proportionate relationship between price and supply?
Businesses are motivated by profit. If prices are rising, existing businesses will be willing to supply increasing amounts of a good because they may make more profit. Or, more businesses will join the market in belief that they can also make a profit. As a result supply in the market increases.
What causes Movement along a supply curve?
When Price Increases or when supply increases
What is a shift in the supply curve?
Movement to the left or right of the entire supply curve when there is any change in the conditions of supply except the price.
What is a Fixed Supply and why may it occur?
(When the amount of a good or service that sellers are prepared to offer for sale at any given price over a period of time stays the same)
Supply will be fixed if it is impossible for sellers to increase supply even when prices rise. Supply at venues where sports matches and other events are held may be fixed.
Factors that cause the supply curve to shift?
.Natural Factors .Production Costs .New technology .Indirect Taxes .Subsidies
How does New Technology affect Supply?
Over a period of time, new technology becomes available that many businesses use in their production processes.
New Technology is more efficient –> Reduced Costs of Production –> Reduced Costs –> Increase Profits –> Firms will want to produce these goods more as they believe that they can make a profit.
How do Indirect Taxes affect Supply?
.When Indirect Taxes are Implemented
.Increased Costs to firms
.Decreased Supply due to lower profits
What is Equilibrium price?
Price at which supply and demand are equal
What is Market Clearing Price?
Price at which the amount supplied in a marker matches exactly the amount demanded
What is the Equation for Total Revenue?
Total Revenue = Price x Quantity
What is Total Revenue?
Amount of money generated from the sale of goods calculated by multiplying price by quantity
What happens to the equlibrium price when there is a shift in demand?
The Equlibrium Price will Rise if demand Increases
The Equlibrium Price will Fall if demand Decreases
What happens to the equlibrium price when there is a shift in supply?
An increase in supply for a product is shown by a shift to the right (Price Equlibrium Decreases)
A decrease in supply for a product is shown by a shift to the left (Price Equilibrium Increases)
What is Price Elasticity of Demand?
The responsiveness of demand to a change in price
What does it mean by inelastic demand?
Change in price results in a proportionately smaller change in the quantity demanded
What does it mean by elastic demand?
Change in Price results in a greater change in the quantity demanded
How to calculate Price Elasticity of Demand?
% change in quantity demanded/ % change in price
What does it mean if the value of PED is less than 1?
Price Inelastic Demand
What does it mean if the value of PED is greater than 1?
Price Elastic Demand
What does it mean if the value of PED is = 0 ?
Perfectly Inelastic (Vertical Line)
What does it mean if PED is = infinity?
Perfectly Elastic (Horizontal Line)
What does it mean if PED = -1?
Unitary Elasticity
Unitary Elasticity?
Where the Responsiveness of demand is proportionately equal to the change in price
What would a Unitary Elastic Graph look like?
curve with a negative gradient
Total Revenue will be the same everywhere
Factors affecting Price Elasticity of Demand?
Availability of Substitutes
Degree of Necessity
Proportion of Income spent on a Product
Time
What is Price Elasticity of Supply?
Responsiveness of Supply to a change in price
What does it mean by Inelastic Supply?
Change in Price results in proportionately smaller change in the quantity supplied
What does it mean by Elastic Supply?
Change in Price results in a proportionately greater change in the quantity supplied
How to Calculate the value of Price Elasticity of Supply?
Percentage change in quantity supplied/ Percentage Change in Price
What does it mean by Perfectly Elastic Supply?
Where producers will supply an infinite amount at the given price
What does it mean by Perfectly Inelastic Supply?
Where the Quantity Supplied is fixed and cannot be adjusted whatever price
What does it mean by Unitary Elasticity of Supply?
A change in Price will be matched by an identical change in the quantity supplied
What does it mean if the PES value is less than 1?
Inelastic Supply
What does it mean if the value of PES is greater than 1?
Price Elastic Supply
What does it mean if PES=0?
Perfectly Inelastic (Vertical Line)
What Does it mean if PES = Infinity?
Supply is Perfectly Elastic (Horizontal)
What does it mean if PES = 1?
Unitary Elasticity
What are the Factors influencing PES?
Factors of Production
Availability of Stocks
Spare Capacity
Time
PES For Manufactured and Primary products?
Businesses that create Manufactured Products will be able to increase production quickly although it may cost more they will just need to hire more workers or indulge in Division of Labour so these will be Price Elastic
Farmers may not be able to increase productivity quicker because crops cannot be grown more quickly so these will be Price Inelastic
What is Income Elasticity of Demand?
Responsiveness of demand to a change in income
How to calculate income elasticity of demand?
Percentage change in quantity demanded/ Percentage change in income
What does the Income Elasticity of demand suggest about the product?
Whether it is a necessity or a Luxury Good
Whether it is a Normal or Inferior Good
What is a Normal Good?
A Normal good is a good whose demand rises when consumer income rises
What are Inferior Goods?
An Inferior Good is a good whose demand falls when consumer incomes decreases.
Why is Price Elasticity useful?
It can help firms predict the effect of a price change on total revenue.
Why may firms be interested in knowing income elasticty of demand?
This is because changes in income in the economy may affect their demand for products so firms will adjust their prices accordingly to the Incomes of their consumers
What is excise duty?
Government tax on certain goods, such as cigarettes, alcoholic drinks and petrol that are sold in the country
What is VAT?
Tax on some goods and services- businesses pay value-added tax on most goods and services they buy and if they are VAT registeres, charge value-added tax on the goods/services they sell
What type of goods and services would Governments impose Indirect Taxes on?
Products that have inelastic demand
Consumers will avoid heavily taxed products if demand for them is elastic
Therefore, governments target goods that are either necessities or have a few substitutes
What type of companies would be subsidies by the government ?
The effect of a subsidy is to move the supply curve to the right
Therefore has to be price inelastic if it is used to try and help the poor by making a good cheaper because
If demand is not price inelastic, an increase in supply will only reduce the price slightly
What is the economy?
System that attempts to solve Basic Economic Problem
What is the Private Sector?
Provision of goods and services by businesses that are owned by individuals or groups of individuals
What is the Public Sector?
Government organisations that provide goods and services in the economu
What are the three types of Private Sector Enterprises?

What are companies?
Where Shareholders own the business. They elect a board of directors to run the businesses on their behalf
What are Shareholders?
People or organisations that own shares in the company
What are the aims of Private Sector Firms?
.Survival (as companies and not going bankrupt)
.Profit Maximisation (Profit Incentivised)
.Growth (to become larger firms)
.Social Responsibillity
Who owns Public Sector Organisations?
.Central Government Departments (UK ministry of defence etc:)
.Public Corporations or state owned enterprises (Where firms appoint people who run the Organisation)
.Local Authority Services (Local Councils)
.Other Public Sector Organisations (BCC, Post Office, Bank of England)
Who do Public Corporations/SOE’s operate?
.Have Seperate Legal identity
.Can Sue or Be Sued
.State Funded (Government provides their Capital)
.All Assets and Liabilities of Public Corporations belong to the state
Aims of Public Sector Services?
.Improving Quality of Services
.Minimising Costs (to stop wasting resources)
.Allowing Social Costs and Benefits
.Some are Profit Incentivised
What are Dividends?

What are Assets?
Things or resources belonging to an individual or a business that has value or the power to earn money
What are Liabilities?
Amount of debt that is owed or must be paid
What are Stakeholders?
Individuals or groups whoa re considered to be an important part of an organisation or of society because they have responsibillity within it and receive advantages from it.
What is a Monetary?
A system of money in a particular country of the world as a whole, and the way that it is controlled by governments and central banks
What are the three types of Economies?
Market or Free Enterprise Economy
Command or Planned Economy
Mixed Economy
What is the Market of Free Enterprise Economy?
Economy that relies least on the public sector for the provision of goods and services. The Vast Majority are provided by private businesses
What is a Command or Planned Economy?
Economy that relies entirely on the public sector to choose, produce and distribute goods. All resources in planned economies belong to the government and the state is responsible for planning, coordinating and organizing the whole production process
What is a Mixed Economy?
Relies on both public sector and the private sector to provide goods and services
What type of goods do private sector firms produce?
Food, Clothes, Leisure and Entertainment
What type of goods do public sector firms produce?
Education. street lighting and roadworks etc: because the private sector may not be able to produce in sufficent quantities due to market failure
How do Private Sector Firms produce goods and services?
Due to competition between existing firms and the need to make profit firms will use production methods that help them to maximise quality and minimise costs.
How do Public Sector Firms produce Goods and Services?
Public Sector serviced will be provided by the government organisations. They will attempt to supply them efficently.
However, some public sector goods are produced by the private sector. (For example. governments are usually responsible for the provision of roads and motorways, however they may pay private sector business to carry out the actual work
Who do Private Sector Firms produce for?
Anyone that can afford the good or service
Who do Public Sector Firms produce for?
Most Public Sector goods are provided free to everyone and paid for from taxes.
What causes Market Failure?
Externalties- (May not take into account the bad things that are caused by this act)
Lack of Competition
Missing Markets (Public Goods are not provide by Private Sector due to lack of profit and they may not produce something that is in low demand)
Lack of Information (If consumers don’t know everything about the nature of their products then it will become inneficient and if Businesses don’t know about the resources and production techniques to make a prodct they will become inneficient)
What are Merit Goods?
Goods that are under provided by the private sector
What are Public Goods?
Goods that are not likely to be provided by the public sector
What might businesses do to make markets work efficiently?
Factors of Production need to mobile
How might Governments intevrene in markets to stop market failure?
Businesses that impose externalities may be heavily regulated or fined for polluting the atmosphere
Gov. can use legislation –> prevent businesses from dominating markets
State money can be used to provide public and merit goods free of charge
Gov. can pass legislation forcing firms to provide information about products
Gov. can help make some factors more mobile (retraining redundant workers)
What are the chracterisitcs of Public goods?
Non excludable (once provided, any individual consumer cannot be excluded from its consumption.)
Non Rivalrous (Everyone can consume it and it doesn’t reduce the amount available to others)
What is a Free Rider?
Individual who enjoys the benefit of a good but allows others to pay for it
Why do Governments produce Public goods?
Free Rider Problem
If private sector were to provide public goods there would be a free rider problem
Not possible to exclude consumption of a public good by an individual consumer
So there is little reason for people to pay for it
Reduced Profit
What is Privatisation?
Act of selling a company or activity controlled by the government to private investors
What are Nationalised Industries?
Where Public Corporations previously part of the private sector that were taken into state ownership
What are Natural Monopolies?
Situation that occurs when one firm in an industry can serve the entire market at a lower cost than would be possible if the industry were composed of many smaller firms
Why does Privatisation take place?
To generate income
Public Sector Organisations were innefficent
To reduce Political Interference
Effect of Privatisation on Consumers?
Higher Quality Goods and lower prices if competition is occuring
If a monopoly then poor quality goods and high prices
Effect of Privatisation in Workers?
Workers are often made redundant
Wages normally cut
Workers will become more productive to save their jobs
Workers may get higher wages as there is no wage restriction
Effect of Privatisation on Businesses?
Increased Profit
Effect of Privatisation on Government?
High revenue
Firms may produce goods that harm the environment but the Government cannot intervene
