Economics Overview and Concepts

Study Notes

Economics Overview

Economics investigates resource allocation to meet limitless wants, focusing on decision-making processes.
Scarcity defines the limited nature of resources in fulfilling society's boundless wants and needs.

Branches of Economics

Microeconomics explores individual economic units, such as consumers, businesses, and markets.
Macroeconomics examines the entire economy, covering inflation, growth, employment, interest rates, and overall productivity.

Incentives

Incentives motivate actions and efforts, frequently driven by financial factors.
Positive incentives encourage behavior to gain rewards, e.g., tax refunds, pay raises, or extra credit.
Negative incentives deter behavior to avoid penalties, e.g., taxes, fines, or academic failures.
Direct incentives are straightforward and immediately recognizable, whereas indirect incentives can be more subtle and harder to identify.

Trade-offs and Opportunity Cost

Trade-offs arise from scarcity, as every decision entails costs, such as choosing between different movie genres.
Opportunity cost is the next best alternative sacrificed when a choice is made, not accounting for all alternatives.

Marginal Thinking

Marginal thinking involves systematically assessing courses of action to evaluate the best decision.
Examples include weighing the benefits and costs of moving furniture when cleaning.
Cost-benefit analysis at the margin means actions should only be taken if the marginal benefits exceed the costs involved.

Comparative and Absolute Advantage

Comparative advantage allows an entity to produce goods at a lower opportunity cost than competitors, facilitating trade benefits.
Absolute advantage refers to an entity's enhanced efficiency in performing a specific economic activity compared to others.
