What is the significance of opportunity cost in decision making?
What is the significance of opportunity cost in decision making?
Opportunity cost represents the next best alternative that is forgone when making a choice, highlighting the true cost of decisions.
How does the law of diminishing marginal utility affect consumer behavior?
How does the law of diminishing marginal utility affect consumer behavior?
The law of diminishing marginal utility suggests that as a consumer consumes more of a product, the additional satisfaction from each unit decreases, affecting their purchasing decisions.
Explain the marginal principle and its role in decision making.
Explain the marginal principle and its role in decision making.
The marginal principle involves making decisions incrementally by evaluating the impact of adding or reducing one more unit, focusing on forward-looking choices.

Study Notes
Scarcity and Economics
- Scarcity arises from insufficient resources to satisfy everyone's wants.
- Economics studies how humans behave in conditions of scarcity.
- Key principles in decision-making include cost-benefit analysis, marginal considerations, opportunity cost, and interdependence.
Principles of Decision Making
- Cost-Benefit Principle: Evaluates the advantages and disadvantages of choices.
- Marginal Principle: Emphasizes decision-making through incremental, forward-looking choices.
- Opportunity Cost: Represents the value of the next best alternative foregone when making a decision.
- Interdependence Principle: Decisions can change based on external factors, such as the preferences of others.
Economic Branches
- Microeconomics: Focuses on individual decisions and their market impacts.
- Macroeconomics: Examines aggregate economic phenomena like overall growth.
Key Concepts
- Utility: Total satisfaction derived from a choice.
- Incentives: Influential factors that drive individual behavior.
- Diminishing Marginal Utility: As consumption of a product increases, the added satisfaction from each new unit tends to decrease.
Cognitive Biases in Economics
- Cognitive Bias: Refers to systematic errors in thinking affecting judgments and decisions.
- Framing Effect: Decisions influenced by how information is presented, impacting evaluation of outcomes.
- Present Bias: Preference for immediate rewards over future benefits, even when future rewards are greater.
- Sunk Cost Fallacy: Continued investment in a decision based on prior commitments rather than current value.
Economic Theories
- Ceteris Paribus: Assumes other variables remain constant when analyzing economic variables.
-
Production Possibilities Frontier (PPF): Visual model showing maximum output combinations for given resources.
- Straight line PPF indicates constant opportunity costs.
- Bowed-out PPF reflects increasing opportunity costs.
Factors of Production
- Resources utilized in creating goods include:
- Natural Resources: Raw materials from the environment.
- Human Resources: Labor force involved in production.
- Capital Resources: Man-made assets used in production.
- Intermediate Goods: Products used to create other goods or services, becoming part of them.
Statements in Economics
- Positive Statements: Objective claims about what is or predicts future occurrences; testable and fact-based.
- Normative Statements: Subjective claims about what ought to be; based on opinions and ethical considerations.
