1.1 - Nature of Economics Flashcards
What is economics?
The allocation of scarce resources to provide for unlimited human wants.
How is economics a social science?
It is concerned with the study of human behaviour.
What does ceteris paribus mean?
All other things being equal. This assumption is needed since economists cannot test model in scientifically controlled experiments.
What is a positive statement?
Based on facts which can be tested as true or false and are value free. E.g. the increase in the national living wage from £7.83 to £8.21 per hour in April 2019 has caused unemployment.
What is a normative statement?
Based on value judgements which can be proven to be true or false. E.g. it is unfair to cut welfare benefits.
What is the role of value judgements?
They have a major influence on economic decision making for consumers and producers. Personal preferences, beliefs and subjective assessment underpin normative economics. Value judgements also have a major role in govt policy making.
The economic problem
Based on scarcity - there are finite resources compares to infinite human wants, so choices have to be made about how to use those resources.
Define opportunity cost
The value of the next best alternative forgone when a decision is made.
What is marginal analysis?
The effects of producing or consuming one extra unit of a good or service - they may both involve both benefits and costs.
What are renewable and non-renewable resources?
Renewable: one whose stock level can be replenished naturally.
Non-renewable: one whose stock level decreases over time.
Production possibility frontiers
They show the maximum potential output of goods an economy can achieve when all its resources are fully and efficiently employed. An outward shift shows economic growth. Inward growth represents economic decline.
Explain the PPFs shape
As more of one good is produced, an increasing amount of the other good is forgone, i.e. opportunity cost rises. This is because not all resources are as efficient as others in the production of both goods.
Capital and consumer goods
Consumer: directly provides utility to the consumer.
Capital: used to produce consumer goods so are an investment.
What is specialisation?
When an individual, firm, region or country concentrates on the production of a limited range of goods and services.
Advantages and disadvantages of specialisation
Advantages: increases productivity, living standards and global output.
Disadvantages: when demand falls there will be structural unemployment
