1.1 The Nature Of Economics Flashcards
Economics as a social science
Economics is primarily considered as a social science, involving the study of people and societies.
Economics is about dealing with scarcity, making choices and, the consequences of those choices.
Microeconomics
Microeconomics studies the behaviour of individuals and firms in making decisions regarding resource allocation.
Positive economic statements
Objective statements based on evidence or facts that can, therefore, be proved or disproved.
Normative economic statements
Subjective statements based on value judgements and cannot be proved or disproved.
Distinguishes Between Positive and Normative Statements
An objective economic analysis should predominantly use positive statements. However, normative statements is often necessary when making policy recommendations.
Scarcity
There are limited resources available to meet unlimited wants and needs.
Factors or Production
Capital, enterprise, labour and land
Capital
The assets and machinery needed in the production process to transform resources into goods.
Entrepreneurship
The strategic initiative and risk taking involved in starting a business.
Labour
The physical human work put in to transform resources into goods.
Land
All natural resources, raw materials, the fertility of the soil and resources found in the sea.
Opportunity cost
The next best alternative that is forgone when a choice is made.
change in y/change in x
Ceteris Paribus
“Other things being equal”
The use of ceteris paribus assumption in building models
The ceteris paribus assumption is valuable for simplifying complex economics relationship, making them easier to analyse and understand. (Cause-and-effects relationships)
The inability in economics to make scientific experiments
- Economics is a social science involving people.
- Consequently, economic policies that may have been effective at one time in one country may not have the same impact at another time or in another country.
The role of value judgement in influencing economic decision making and policy
- Economists tend to use positive statements to back up normative statements.
- Value judgements can influence economic decision making and policy. Different economists may make different judgements from the same statistic.
Renewable resources
A natural resource that can be replaced naturally after use.
eg. Solar energy, wind power, wood and fish.
Non-renewable resources
Natural resources where continued consumption will eventually result in their exhaustion.
eg. Oil, copper, platinum.
