Study Notes
Opportunity Cost and Marginal Analysis
- Opportunity Cost: The value of the best alternative forgone when choosing one option over another.
- Marginal Analysis: Decision-making process that compares additional benefits (marginal benefits) to additional costs (marginal costs).
Production and Resource Allocation
-
Production Possibilities Curve (PPC): A graphical representation of the maximum combinations of two goods that an economy can produce with its available resources.
- The PPC is bowed outward due to increasing opportunity costs, reflecting the trade-offs in resource allocation.
- Underutilization of Resources: Occurs when a nation operates inside its PPC, indicating inefficiencies in resource use.
Demand and Supply
-
Demand: Represents the relationship between the price of a good and the quantity consumers are willing and able to purchase.
- Law of Demand: As the price of a good decreases, the quantity demanded increases, assuming all other factors remain constant.
- Consumer Income and Demand: An increase in consumer income typically leads to an increase in demand for normal goods.
- Supply: Represents the relationship between the price of a good and the quantity producers are willing and able to sell.
- Market Equilibrium: Occurs when the quantity demanded equals the quantity supplied, leading to a stable price and no shortages or surpluses.
-
Surplus: Occurs when the quantity supplied exceeds the quantity demanded.
- Typically leads to a decrease in price to encourage consumers to purchase the excess supply.
-
Shortage: Occurs when the quantity demanded exceeds the quantity supplied.
- Often leads to an increase in price as consumers compete for the limited supply.
Price Elasticity of Demand
-
Price Elasticity of Demand (PED): Measures the responsiveness of the quantity demanded to changes in price.
- A PED greater than 1 indicates elastic demand, meaning a change in price leads to a proportionally larger change in quantity demanded.
- A PED less than 1 indicates inelastic demand, meaning a change in price leads to a proportionally smaller change in quantity demanded.
Factors Affecting Demand
- Income Effect: When prices decrease, consumers feel an increase in purchasing power, allowing them to buy more goods.
- Substitution Effect: When prices decrease, a good becomes relatively cheaper compared to its alternatives, leading consumers to substitute it for other goods.
-
Complementary Goods: Goods that are typically consumed together.
- An increase in the price of one good leads to a decrease in the demand for its complement.
-
Substitute Goods: Goods that can be used in place of each other.
- An increase in the price of one good leads to an increase in the demand for its substitute.
- Consumer Expectations: Expectations of future price increases can lead to an increase in current demand as consumers try to buy goods before prices rise.
- Consumer Tastes: Changes in consumer preferences can shift the demand curve.
Government Intervention in Markets
-
Price Ceilings: Maximum prices set by the government.
- If set below the equilibrium price, price ceilings can lead to shortages as producers are unwilling to supply the quantity demanded at the lower price.
-
Price Floors: Minimum prices set by the government.
- If set above the equilibrium price, price floors can lead to surpluses as producers are willing to supply more than consumers demand at the higher price.
- Market Surplus: Governments may intervene to address persistent surpluses by buying excess supply or providing subsidies to producers.
Perfect Competition
-
Perfect Competition: A market structure with many firms producing identical products, leading to minimal control over prices by individual firms.
- Perfectly competitive markets tend to be efficient in the long run, with firms producing at the lowest possible cost.
Cost and Revenue Analysis
- Marginal Cost: The additional cost incurred from producing one more unit of a good.
- Marginal Revenue: The additional revenue generated from selling one more unit of a good.
- Profit Maximization: Firms aim to maximize profits by producing where marginal cost equals marginal revenue.
Economic Systems
- Market System: A system where decisions regarding production and consumption are guided by market signals (supply and demand) and competition, allowing for decentralized decision-making.
- Command Economic System: Characterized by government ownership of resources and centralized decision-making, contrasting with the decentralized decisions in market systems.
- Laissez-Faire Capitalism: Supports minimal government intervention, arguing that free markets best promote human welfare and economic efficiency.
Other Important Concepts
- Specialization: Allows workers to focus on specific tasks, increasing efficiency by reducing time wasted switching between different activities.
- Private Ownership: Encourages innovation and efficiency by allowing individuals and firms to make decisions on how to use and dispose of resources.
- Rational Self-Interest: Individuals and firms make decisions based on what they believe is best for themselves, with the aim of maximizing personal utility or profits.
