1.1 - Economics as a Social Science
Social sciences and economics as a social science
Social sciences are academic fields that examine human behaviour in a structured way, covering areas like psychology, anthropology, and political science. Economics fits into this group by focusing on human actions and social connections, using a methodical approach to gather and analyse data. This involves creating hypotheses about social events that can be tested and potentially disproved.
Key features of the social scientific method in economics
- Data collection and analysis - Economists gather information on economic behaviours and patterns, then study it to draw conclusions.
- Hypothesis formulation - Ideas about economic phenomena are developed in ways that allow them to be tested against real-world evidence.
- Application to social phenomena - This method helps explain how people make decisions in areas like spending, saving, and resource use.
The branches of economics: microeconomics and macroeconomics
Economics splits into two primary areas, each looking at different scales of economic activity.
Microeconomics
Microeconomics looks at the smaller, individual elements of the economy. It focuses on how single units operate and interact.
Key areas of focus:
- Individual firms and their production decisions.
- Consumers and their buying choices.
- Specific markets, such as those for goods like cars or services like banking.
Macroeconomics
Macroeconomics examines the economy on a large scale, dealing with overall totals and broad trends.
Key areas of focus:
- The total level of unemployment across the whole economy.
- The overall output of goods and services, including how it grows over time.
- The average price level for all items, often linked to inflation.
The core central concepts in economics
Economics revolves around several core ideas that explain how societies manage resources and make decisions.
| Concept | Description |
|---|---|
| Scarcity | The basic issue all societies deal with, where human desires exceed what can be produced with limited resources. Wants are endless, but supplies are finite. |
| Choice | Because of scarcity, decisions must be made about which goods or services to create and in what amounts. This involves weighing options and considering their short-term and long-term effects. |
| Efficiency | Using limited resources wisely to avoid waste. Allocative efficiency means producing the best mix of items, while technical efficiency focuses on minimising waste in production. |
| Equity | The notion of fairness, which varies by viewpoint. In economics, it often means addressing unequal distributions of income or wealth, with debates on whether markets or governments should promote more even outcomes. |
| Economic well-being | The standard of living in an economy, covering secure access to income, wealth, jobs, and housing. It includes meeting essentials like food, health care, education, and transport, plus the freedom to make financial choices and feel secure over time. |
| Sustainability | Ensuring current needs are met without harming future generations' ability to do the same, often tied to responsible environmental management. |
| Change | The constant shifts in the economic landscape, including institutional, structural, technological, economic, and social developments. Economics studies these shifts in factors rather than static levels. |
| Interdependence | How economic players like consumers, producers, governments, and countries affect each other. Actions by one group can have planned or unexpected effects on others. |
| Intervention | Government involvement in markets, even though markets are seen as effective for organising activity. Markets can fail, prompting intervention, but its extent is debated, and success is not assured. |
