1.1 - Nature of Economics

1.1.1 - Economics as a social science

What is meant by economics as a social science?

Economics is a social science because it studies people, societies and their interactions.

What is an economic model?

An economic model is a simplified version of reality used to help you understand economic relationships.

Why do economists use models?

Economists use models to simplify complex reality so you can understand how economic interactions work more clearly.

What is an assumption in economics?

An assumption in economics is a generalisation about behaviour, choices or likely outcomes that helps you build a model.

Why do economists need to make assumptions when developing models?

Economists need assumptions because human behaviour is complex and there are constantly changing variables in the real world.

What does ceteris paribus mean?

Ceteris paribus means “all other variables remain constant”.

Why is the ceteris paribus assumption used in economic models?

Economists use ceteris paribus because there are so many variables affecting economic behaviour that it would be hard to analyse everything at once. It lets you isolate the relationship between two variables by assuming all others stay the same.

What does ceteris paribus allow economists to examine?

Ceteris paribus allows economists to examine the relationship between variables while keeping all other factors constant.

1.1.2 - Positive and Normative Economic

What is a positive economic statement?

A positive economic statement is an objective statement of fact that can be tested as true or false.

What is a normative economic statement?

A normative economic statement is a value judgement about what should happen in the economy. It is based on opinions or beliefs, so it cannot be proved true or false.

What is the key difference between positive and normative statements?

positive statements are factual and testable, while normative statements are opinions or value judgements about what should happen.

What is meant by a value judgement?

A value judgement is an opinion about what is good, bad, right or wrong. In economics, it is used in normative statements about what should happen.

1.1.3 - The Economic Problem

What is the basic economic problem?

there are limited resources but unlimited wants and needs

What is a renewable resource?

A renewable resource is one that can be used repeatedly and is naturally replenished.

What is a non-renewable resource?

A non-renewable resource is a resource that exists in finite supply and is used up faster than it can be replaced by nature.

Give examples of renewable resource.

• Wind

• Solar energy

• Hydroelectric power

• Tidal power

• Biomass

Give examples of non-renewable resources.

• Oil

• Coal

• Natural gas

• Nuclear fuel such as uranium

What is an opportunity cost?

An opportunity cost is the next best alternative forgone when making economic choice.

What are the three main groups of economic agents?

• Consumers

• Producers

• The government

What is the importance of opportunity cost to consumers?

It helps you decide whether a purchase is worth what you are sacrificing.

What is the importance of opportunity cost to producers?

Opportunity cost is important to producers because it helps them decide what to produce and choose the option with the best return.

What is the importance of opportunity cost to governments?

Opportunity cost is important to governments because Governments must choose how to allocate limited resources to get the best outcome.

1.1.4 - Production Possibility Frontiers

What is a production possibility frontier (PPF)?

A PPF is a model that shows the maximum possible output of two goods/services an economy can produce when it uses all resources efficiently.

What does a PPF show about an economy's maximum productive potential?

It shows:

• the economy’s maximum productive potential

• the trade-off between the two goods

• whether production is efficient, inefficient, or unattainable

What does a point on a PPF represent?

A point on a PPF represents productive efficiency.

What does a point inside a PPF represent?

A point inside a PPF represents inefficiency.

What does a point outside a PPF represent?

A point outside a PPF is unattainable with the economy’s current resources and technology.

How can a PPF illustrate economic growth?

A PPF illustrates economic growth when the entire curve shifts outwards.

This means the economy can produce more of both goods because its productive capacity has increased

How can a PPF illustrate economic decline?

A PPF illustrates economic decline when the entire curve shifts inwards.

This means the economy can produce less of both goods because its productive capacity has fallen.

What is the difference between a movement along a PPF and a shift of a PPF?

A movement along a PPF happens when the economy changes the allocation of existing resources between the two goods. Total resources and productive capacity stay the same, so you get more of one good and less of the other.

A shift of the PPF happens when the economy’s productive capacity changes:

What is a capital good?

A capital good is a good used to help produce other goods and services rather than being bought for direct consumption.

What is a consumer good?

A consumer good is a good bought for direct use or satisfaction by households

1.1.5 - Specialisation and the Division of Labou

What is specialisation?

Specialisation is when an individual, firm, region or country focuses on producing one good or a small range of goods/services.

What is the division of labour?

The division of labour is when a production process is broken into several smaller tasks

Who was Adam Smith?

Adam Smith was a Scottish economist often called the “father of Economics”.

He wrote The Wealth of Nations in 1776 and explained ideas such as:

• specialisation

• the division of labour

• the price mechanism

• the idea of the invisible hand

What are the advantages of the division of labour?

• Higher productivity: workers become quicker and more skilled at one task

• Lower unit costs: firms can produce more cheaply

• Lower prices: cost savings may be passed on to consumers

• Higher profits: firms may earn more, which can support higher wages

• More output: firms may be able to sell beyond their local market, even internationally

• More jobs: it can create many low-skilled jobs

What are the disadvantages of the division of labour?

• Boredom from repeating the same task

• Lower motivation, which can reduce productivity

• Poorer quality if workers lose interest

• Higher worker turnover as people leave for more interesting jobs

• Less variety in products

• If workers lose their jobs, they may find it hard to get new work because they are only trained in one skill

What are the advantages of specialisation

• Higher productivity because workers/firms become more skilled

• Lower costs per unit

• Lower prices for consumers

• Higher profits for firms

• More competition and better quality in some markets

• Greater output, so firms or countries can sell more, even internationally

What are the disadvantages of specialisation?

• Boredom and lower motivation for workers

• Less variety in output

• Harder to find new work if a worker loses their job, because they may only have one skill

• Over-dependence on other countries or industries

• Resource depletion if a country keeps using the same resources

• In trade, some firms or industries may fail to compete globally, causing structural unemployment

What are the advantages of specialisation for trade?

• Lower prices

• Greater variety of goods and services

• Better quality because competition increases

• Economies of scale, which improve efficiency

• Higher economic growth

• Improved living standards

What are the disadvantages of specialisation for trade?

• Some firms cannot compete globally and may go out of business

• This can cause structural unemployment

• Countries may become over-dependent on other countries’ resources

• If conflict or disruption happens, this can create serious problems

• Specialisation can lead to resource depletion over time

• Countries may become too focused on one product or industry, making them vulnerable to price changes

What are the four functions of money and explain them?

• Medium of exchange: you use money to buy goods and services instead of bartering

• Measure of value: money lets you compare the value of different goods and services

• Store of value: money can be saved and used later

• Method of deferred payment: money lets you pay for goods or debts in the future

1.1.6 - Free Market, Mixed and Command Economies

What is a free market economy?

A free market economy is an economic system where resources are allocated by the forces of supply and demand, with little or no government intervention.

What is a command economy?

A command economy is an economic system where the state owns the resources and the government controls what is produced, how it is produced, and who receives the goods and services.

What is a mixed economy?

A mixed economy is an economic system where most resources are allocated through the market, but the government also intervenes to influence production, consumption, and distribution.

What is the role of Adam Smith in the development of free market economic ideas?

Adam Smith helped develop free market ideas by arguing that:

• people act in their own self-interest

• markets work best with little government intervention

• the price mechanism helps allocate resources efficiently

• government still has a limited role in providing public and merit goods

What is the role of Friedrich Hayek in the development of free market economic ideas?

Hayek supported free markets and argued that:

• government intervention should be limited

• central planning is inefficient because planners lack information

• markets are better at allocating resources

• too much control can cause shortages and surpluses

What is the role of Karl Marx in the development of command economy ideas?

Marx supported command economies because he believed:

• free markets cause inequality

• capitalists exploit workers

• the state should own the means of production

• a central planner should decide resource allocation

What are the main characteristics of a free market economy?

A free market economy has these main characteristics:

• No government intervention in allocating resources or distributing goods and services

• Private ownership of factors of production

• Decisions are made by consumers and firms

• Prices are determined by supply and demand

• Firms are motivated by profit

• There is usually competition, which can lead to lower prices, better quality and innovation

What are the main characteristics of a command economy?

A command economy has these main characteristics:

• All resources are owned by the state

• The government controls the distribution of goods and services

• A central planner decides what, how and for whom to produce

• There is usually little or no competition

• The aim is social equality, not profit maximisation

• Workers may receive the same wage regardless of job

What are the main characteristics of a mixed economy?

A mixed economy combines features of a free market and a command economy:

• Individuals, firms and the government all own factors of production

• Resources are allocated by both markets and government intervention

• The government may use taxation and spending to redistribute income

• It provides public goods and merit goods like defence, healthcare and education

• There is usually private sector activity alongside a public sector

• It encourages competition while ensuring social welfare.

What are the advantages of a free market economy?

A free market economy can have these advantages:

• Profit incentive motivates people to work and start businesses

• Competition can lead to better quality goods and services

• Competition can also lead to lower prices

• It encourages innovation and product development

• It can create a greater variety of goods and services

• It can lead to a more efficient allocation of scarce resources

• It may improve standards of living through higher profits, incomes and wealth

What are the disadvantages of a free market economy?

A free market economy can have these disadvantages:

• Wealth becomes concentrated in the hands of a few

• This can increase inequality

• Firms may lower quality to increase profits

• Workers can be exploited

• Environmental damage and resource depletion may be ignored

• Monopolies can develop through mergers and acquisitions

• This can lead to consumer exploitation and higher market power

What are the advantages of a command economy?

A command economy can have these advantages:

• Less inequality because the goal is social equality

• Workers may receive the same wage, which reduces income gaps

• Less unemployment can occur

• The government can direct resources quickly towards urgent priorities

• State ownership can help avoid consumer exploitation from high prices

What are the disadvantages of a command economy?

A command economy can have these disadvantages:

• Lower incentives to work hard or gain difficult skills, since wages may be similar

• Less innovation and product development because there is little competition

• Inefficiency can happen because central planning often leads to shortages or surpluses

• Black markets may develop to deal with shortages

• Most people may have limited access to higher living standards

• Personal freedoms are restricted

What is the role of the state in a mixed economy?

In a mixed economy, the state has a limited but important role:

• It uses taxation to raise revenue

• It uses government spending to redistribute income

• It provides essential goods and services

• It funds welfare, such as unemployment benefits, healthcare and pensions

• It also spends on infrastructure, merit goods like schools, and public goods like national defence

What is The price mechanism?

The price mechanism is the way prices are determined by the interaction of demand and supply.

What is the 3 main functions of the price mechanism and explain them?

• Rationing: higher prices limit demand so scarce goods go to those who can afford them

• Signalling: rising/falling prices tell firms and consumers where resources are needed

• Incentive: higher prices encourage firms to produce more; lower prices encourage consumers to buy more
