Section 1 - The Economic Problem Flashcards
What do economists do to compensate for being unable to control one variable at a time?
To get around the problem of the existence of multiple variables in an economy, economists use the assumption known as ceteris paribus.
Ceteris Paribus - definition
Latin for ‘all other things remaining equal’.
When do economists use ceteris paribus?
> When they are looking at the relationship between 2 factors.
E.g. price and demand.
They’ll assume only these 2 factors change and all other factors (income, changes in taste) that would have an effect on any other variable being considered remain the same.
What do economists use ceteris paribus for?
To develop theories and models, and make predictions.
Economic decision vs economic sense
> Economic decisions might not always make economic sense.
Economics deals with real people so keep in mind decisions made by individuals, firms or governments will often be based on opinions or judgements.
What might decisions be based on?
- Normative statements.
- Moral views and value judgements.
- Political judgements.
- Short-term positive consequences.
Moral views and value judgements
E.g. the view that people shouldn’t live in poverty, so wealth should be shared.
Political judgements
E.g. lowering taxes may win votes for government.
Short-term positive consequences…
of a decision, regardless of long-term consequences.
E.g. reducing taxes may win an election, but it will reduce the government’s income and may lead to public spending cuts.
How many types of economic statements are there?
2
What are the 2 kinds of statements you can make in economics?
- Positive Statements
2. Normative Statements
Positive statements
> Are objective statements that can be tested by referring to the available evidence.
E.g. “a reduction in income will increase the amount of people shopping in pound shops”.
With suitable data collected over a period of time, you should be able to tell if the above claim is true or false.
Positive claims are important because they can be tested to see whether economic ideas are correct.
Normative statements
> Are subjective statements which contain a value judgement - they’re opinions.
E.g. “the use of fossil fuels should be taxed more highly than the use of renewable fuels”.
It’s not possible to say whether the above statement is true or not - only whether you agree or disagree with it.
Normative statements are also important because value judgements influence decision-making and government policy, e.g. party may increase taxes on rich and distribute to poor.
Short definition of economics
How best to satisfy infinite desires using limited resources.
What is the fundamental economic problem?
> There’s only a limited amount of resources available to satisfy infinite desires.
i.e. resources are scarce.
The basic economic problem
How can the available scarce resources be used to satisfy people’s infinite needs and wants as effectively as possible?
Factors of production - explaination
> The scarce resources (inputs) used to make the things people want and need (outputs) can be divided into four factors of production.
Individuals and firms are rewarded dor providing these factors e.g. with a wage or rent.
What are the factors of production?
- Land
- Labour
- Capital
- Enterprise
Factors of production - Land
> Including all the natural resources in and on it.
As well as actual ‘territory’, land includes all the Earth’s natural resources.
Nearly all things that fall under the category of land are scarce - there aren’t enough natural resources to satisfy the demands of everyone.
One exception is air, but even this isn’t as simple as it first looks.
Earth’s natural resources
> Non- renewable resources, such as natural gas, oil and coal.
Renewable resources like wind or tidal power, or wood from trees.
Materials extracted by mining (e.g. diamonds and gold).
Water.
Animals found in an area.
Land - air
> Air isn’t usually considered a scarce resource as there’s enough for everyone.
But doesn’t mean all air is equally good - polluted air.
In fact, the environment is considered by some people to be a scarce resource.
It’s a free good.
Free good
> Something that is not scarce or has no price, such as atmosphere, sunlight, or gravity; something that can be obtained at no cost.
Impossible to sell it.
Economic good
> Things that are scarce and which can therefore be traded.
Factors of production - labour
> Labour is the work done by those people who contribute to the production process. The population who are available to do work is called the labour force.
There’s unemployed.
Also there’s people who aren’t in paid employment but still provide things people need or want, e.g. homemakers.
Different people have different levels of education, experience or training. These factors make some people more ‘valuable’ or productive than others - they have a greater amount of human capital.
UK - no. of working age with a job is arounf 30 million.
Labour force - definition
> The population who are available to do work is called the labour force.
Unemployed
People who are capable of working and are old enough to work, but don’t have a job.
Human capital
> the skills and knowledge gained by a worker through education, experience and training.
These factors can make some people more ‘valuable’ or productive in the workplace than others - they have a greater amount of human capital.
Factors of production - capital
> Capital is the equipment, factories and schools that help to produce goods or services.
Capital is different from land because capital has to be made first.
Much of an economy’s capital is paid for by the government - e.g. a country’s road network is a form of capital.
Factors of production - enterprise
> Enterprise: willingness to take a risk to make a profit.
Enterprise refers to people (entrepreneurs) who take risks and create things from the other three factors of production.
They set up and run businesses using any of the factors of production available to them.
If the business fails, they can lose a lot of money. But if the business succeeds, the reward for risk-taking is profit.
What does scarcity require?
The careful allocation of resources.
Economic activity
> Economic activity involves combining the factors of production to create outputs that people can consume.
The purpose of any economic activity is to increase people’s economic welfare by creating outputs that satisfy their various needs and wants.
In economics a wide range of things count as economic activity.
Examples of economic activiy
- The making of goods and the provisions of services (i.e. creating outputs).
- Consumption (i.e. buying or using) is also a form of economic activity. When you consume something, you’re trying to satisfy a need or a want. You can consume both goods and services.
- DIY, bringing up children (even though you might not get paid for it).
Goods - definition
‘Physical’ products you can touch - such as washing machines, books or a new factory.
Services - definition
‘Intangible’ things - such as medical check-ups, teaching or train journeys.
What leads to the three fundamental questions?
An endless array of things that could be produced and consumed, but only limited resources, this leads to three fundamental questions.
What are the 3 fundamental questions?
- What to produce?
- How to produce it?
- Who to produce it for?
Agents - definiton
particitipants
Agents - types
> Agents in an economy can usually be thought of as:
- Producers - firms or people that make goods or provide services.
- Consumers - people of firms who buy the goods and services.
- Governments - a government sets the rules that other participants in the economy have to follow, but also produces and consumes goods and services.
Economic agents
> Have to make decisions on how resources are allocated.
In a market economy, all economic agents are assumed rational, which means they’ll make the decisions that are best for themselves.
These decisions will be based on economic incentives, such as making profit or paying as little as possible for a product.
What helps try to answer the fundamental questions?
> Considering people’s incentives.
1. What to produce? This will be those good that firms can make a profit from.
2. How to produce it? Firms will want to produce the good in the most efficient way they can, in order to maximise their profits.
3. Who to produce it for? Firms will produce goods for consumers who are willing to pay for those goods.
So in effect consumers decide what is to be produced. Producers won’t want to produce things that nobody wants to buy.
Examples of economic agents decisions on resource allocation
> Producers: decide what to make, and how much they’re willing to sell it for.
Consumers: have to decide what they want to buy, and how much they are willing to pay for it.
Governments: have to decide how much to intervene in the way producers and consumers act.
PPF
> Production possibility frontiers (PPFs) - also known as production possibility curves (PPCs) or production possibility boundaries (PPBs) - show the maximum amount of two goods or services an economy can produce.
What do Production Possibility Frontiers show?
> The basic problem in Economics is how best to allocate scarce resources.
A PPF shows the options that are available when you consider the production of just two types of goods or services.
PPF example
> They show the maximum possible output that can be made using the existing level of resources in an economy.
Points on the curve are achievable however, only when all the available resources are used as efficiently as is actually possible.
There’s a trade-off between the x and y-axis as to do more of one, you have to do less of the other.
All the different points on the PPF represent a different choice about how to use the available scarce resources.
What is a trade-off? PPF.
> A trade-off is when you have to choose between conflicting objectives because you can’t achieve all your objectives at the same time.
It involves compromising, and aiming to achieve each of your objectives a bit.
Involves an opportunity cost.
