Study Notes
Economics: Introduction
- Origins: The word "economy" comes from the Greek word oikonomos, meaning "one who manages a household." This reflects the fundamental similarity between managing a household and managing a society.
- Resource Allocation: Societies allocate jobs and resources among individuals, deciding who produces what and who receives goods and services.
- Scarcity: Resources are limited, meaning that not all wants can be satisfied. Economics studies how societies manage these limited resources.
Ten Principles of Economics
-
Principle 1: People Face Trade-offs: Choices involve sacrifices, requiring individuals to give up something to gain another.
- Examples: Students allocate time between studying, leisure, and work. Societies choose between spending on defense ("guns") and consumer goods ("butter").
- Efficiency vs. Equality: Trade-offs exist between maximizing benefits from resources (efficiency) and ensuring even distribution (equality).
-
Principle 2: The Cost of Something Is What You Give Up to Get It: Opportunity cost is the benefit of the best alternative forgone when making a choice.
- Example: Attending college involves the opportunity cost of lost income from not working.
-
Principle 3: Rational People Think at the Margin: Rational decision-makers evaluate available options to achieve their goals by considering marginal changes.
- Example: A diner decides whether to take an extra spoonful of mashed potatoes, considering the marginal benefit and cost. Airlines may sell standby tickets at a lower price when the marginal cost of accommodating an extra passenger is low.
-
Principle 4: People Respond to Incentives: Incentives, factors that motivate action, influence economic decision-making.
- Example: Higher apple prices discourage consumption and incentivize producers to produce more apples.
Economists and Policy
-
Role of Economists: Economists advise policymakers on economic policy matters, such as budgeting, taxation, and labor markets.
- Example: The Council of Economic Advisers guides economic policy for the President.
- Influence of Economic Ideas: Economic theory can significantly influence policy decisions.
Why Economists' Advice is Not Always Followed
-
Complexities of Policymaking: Real-world policy decisions are more complex than idealized textbook models.
- Factors: Political factors like communications, media perceptions, and legislative considerations impact policy implementation.
- Multifaceted Decision-Making: Presidents consult with other experts besides economists, including communications and public relations professionals, impacting policy adoption.
Why Economists Disagree
- Disagreement on Theories: Economists may have differing views on the validity of positive theories explaining how the economy works, leading to different interpretations of data and events.
- Different Values: Economists' personal values influence their normative perspectives on policy goals, resulting in divergent policy recommendations.
Markets and Competition
-
Definition of a Market: A market comprises buyers and sellers of a specific good or service.
- Buyers: Determine demand.
- Sellers: Determine supply.
- Types of Markets: Markets can be organized (e.g., agricultural commodities) or less structured (e.g., local ice cream markets).
- Competition: In a competitive market, numerous buyers and sellers interact, ensuring no single entity significantly influences price.
- Perfectly Competitive Market: A market with many buyers and sellers of homogenous products, where no single participant can set the price independently.
The Demand Curve
- Relationship between Price and Quantity Demanded: The demand curve illustrates the inverse relationship between the price of a good and the quantity demanded by consumers.
-
Law of Demand: As price increases, quantity demanded decreases, and vice versa.
- Example: Higher ice cream prices lead to fewer cones purchased, while lower prices encourage higher demand.
- Demand Schedule: A table showing the quantity demanded at various prices.
- Market Demand: Combines the individual demands of all consumers to determine total demand for a good or service at each price level.
Shifts in the Demand Curve
-
Demand Curve Shifts: Occur when factors other than the price of a good influence the quantity demanded at each price level.
- Increase in Demand: Shifts the curve to the right, meaning more is demanded at every price.
- Decrease in Demand: Shifts the curve to the left, meaning less is demanded at every price.
-
Factors Causing Shifts:
- Income: Lower income reduces demand for normal goods but increases demand for inferior goods.
- Prices of Related Goods: A substitute good's falling price lowers demand for the original good. A complement good's falling price raises demand for the original good.
- Tastes: Consumer preference changes impact demand.
- Expectations: Future income or price changes influence current demand.
- Number of Buyers: More buyers increase demand at every price point.
