Economics as a social science
Concerns human behavior and societal organization.
Focuses on activities that satisfy needs and wants.
Microeconomics
Examines behavior of individual decision-making units.
Two main groups: Consumers (households) and Firms (business).
Analyzes choices and consequences in markets, determining prices.
Macroeconomics
Looks at the economy as a whole, using aggregate data.
Economic Well-being
Dimensions: prosperity, financial satisfaction, quality of life factors (health, education, social connections).
Interdependence
Economic decision-makers rely on each other across levels (individuals, communities, nations).
Scarcity
Limited resources vs. unlimited wants; studies allocation to satisfy needs.
Efficiency
Optimal use of scarce resources; focuses on minimizing waste and maximizing output.
Change
Represents shifts in economic conditions, influencing supply and demand.
Equity
Refers to fair distribution of income and opportunities.
Sustainability
Ensures current actions do not hinder future generations' resource availability.
Scarcity leads to making choices about production and consumption (e.g., guns vs. butter).
Economics is defined as the study of choices in the face of scarcity.
Sustainable development: growth that meets present needs without compromising future generations.
Land: Natural resources (e.g., minerals, forests).
Labor: Human physical and mental effort.
Capital: Man-made resources (e.g., machinery, tools) and financial instruments.
Entrepreneurship: Innovation and risk-taking to organize resources.
Opportunity cost: The value of the next best alternative sacrificed when making a choice.
Example: Choosing shoes over a book incurs the opportunity cost of the book.
What/how much to produce?
How to produce?
For whom to produce?
Market vs. Command Economies
Market systems focus on private ownership; command economies are government-directed..
Illustrates maximum combinations of two goods produced using resources efficiently.
Points on and inside the curve represent efficient and inefficient production respectively.
Depicts the economy's interactions; focuses on households and firms without government or international trade.
Leakages and Injections
Leakages (savings, taxes, imports) withdraw income, whereas injections (investment, government spending, exports) add income.
Earn revenue, support firms, influence production/consumption, correct market failures, and promote equity.
Price Ceilings: Max prices designed to aid affordability but lead to shortages.
Price Floors: Min prices to support income (e.g., minimum wage), leading to surpluses.
Indirect Taxes: Impact spending; can discourage demerit goods consumption.
Subsidies: Governments provide financial aid to firms/individuals to encourage production of merit goods.
Responsiveness of demand to price changes.
Responsiveness of demand to income changes.
Measures how responsive supply is to price changes.
Understanding the foundations of economics provides insight into decision-making at both micro and macro levels, emphasizing the importance of resource allocation, market mechanisms, and the role of government in economic activities.
