Study Notes
Economics is a social science that studies how resources are allocated in the production, distribution, and consumption of goods and services. It is divided into Microeconomics and Macroeconomics, focusing on individual and whole economy interactions, respectively.
- Scarcity — the central economic problem where resources are limited but human wants are unlimited.
Example: Choosing between spending money on a movie or a pizza due to limited funds. - Choice — decisions made to allocate scarce resources optimally.
Example: Deciding to watch a movie instead of buying a pizza. - Efficiency — maximizing output from limited resources, minimizing waste.
Example: Producing the most desirable combination of goods with available resources. - Equity — fairness in economic policies, often subjective.
Example: Fair distribution of wealth in society. - Sustainability — meeting current needs without compromising future generations.
Example: Using renewable energy to prevent resource depletion. - Opportunity Cost — the value of the next best alternative forgone.
Example: The benefit of eating pizza forgone when choosing to watch a movie. - Free Market Economy — resources owned by private individuals, prices determined by supply and demand.
Example: A capitalist system with minimal government intervention. - Planned Economy — resources owned by the government, allocation based on government objectives.
Example: A socialist system with government-controlled production. - Mixed Economy — combines elements of free market and planned economies.
Example: Both private and public sectors manage resources.
