Nature of economics 1.1 Flashcards
What does ceteris paribus mean
Everything else remains equal.
This is the most important assumption for an economist to create functioning models
What is a positive statement
Positive statements describe the world as it is. They are objective statements that can be proved.
E.g the proposal of the new high speed rail HS2. If the exact benefits exceed the exact costs, you could say the project is worth doing. This is positive analysis. However, you may not always know costs & benefits perfectly.
What is a normative statement
Normative statements describe how the world should be. They are opinions that contain value judgements.
E.g imagine an economist argued for higher unemployment benefits during a recession, because a rich country should take care of its citizens. This is normative analysis.
What is a value judgement
Value judgments are often found in normative statements. They are judgements about society that cannot be quantified and tested.
E.g the homelessness problem in Oxford needs to be addressed and funds should be redistributed to do this. This judgement is within a normative statement.
Value judgements affect economic decision-making, so normative statements are important.
What is the economic problem
There are not enough resources on earth to satisfy humans’ unlimited wants and needs.
The basic economic problem involves working out how to allocate limited resources as effectively as possible to satisfy people’s unlimited wants and needs.
Define opportunity cost
The benefit Forgone of the next best alternative
People face a tradeoff when they make choices.
If you choose to buy a video game, you cannot spend that income on movies.
What you would use the money from the video game to buy instead.
Issues of opportunity cost
-Not all factors have alternatives.
-Some alternatives are unknown.
-Agents may lack information on alternatives.
-It can be difficult to switch some factors to another use.
What incentives do different economic agents base their decisions on
-For firms this might be profit maximisation.
-Producers must decide what products to make and the selling price of products.
-Consumers decide what products to purchase and how much they want to spend on products.
-Governments decide how much they should get involved in the production and consumption process.
What are the PPF details
The PPF shows economy at its maximum productive potential.
Society can choose any two goods on or inside the PPF.
The opportunity cost is the slope of the PPF.
The PPF is curved because of the law of diminishing returns.
As you increase units of one resource and keep other factors constant, the marginal benefit from the extra units will eventually start to decline.
What does it mean if an economy is operating inside and on the PPF curve
When an economy operates inside the PPF, it means that it is not utilizing all its resources efficiently.
When an economy operates on the PPF, it is producing at maximum efficiency. This means that all available resources are being used optimally, and the economy is producing the maximum possible output of goods and services.
What can cause a PPF curve to shift
The PPF shifts outward if there is economic growth.
This is because the productive capacity of the economy has increased.
E.g. this could be caused from improvements in technology.
But this improvement isn’t necessarily equal across all products.
E.g. an improvement in the technology to produce cars isn’t necessarily going to affect the ability to produce butter.
Allocative efficiency
Allocative efficiency occurs when the resources in an economy are allocated in such a way that maximizes the total benefit to society. It is achieved when the price of a good or service reflects the marginal cost of producing it, meaning that the amount produced is exactly what consumers demand at that price.
Productive efficiency
Productive efficiency occurs when goods and services are produced at the lowest possible cost. This means that the production process is using the optimal combination of inputs to produce a given output, minimizing waste and maximizing output.
4 Factors of production
Capital - Resources used to produce goods or services.
Entrepreneurship - Entrepreneurship refers to the ability and willingness of an individual to combine the other factors to create goods or services.
Land - Natural resources used in production. Raw materials, minerals, land
Labour - all productive human effort both physical and mental paid or unpaid
CELL
Define specialisation
Specialisation is the production of a limited range of goods by a company/individual/country which means that trade is essential as it is the only way
they are able to access all that they need.
