Study Notes
Scarcity and Choice
- Scarcity: Resources are limited, unable to fulfill unlimited human needs and wants.
- Choice: The act of deciding what to produce and what to forgo in the face of scarcity.
- Efficiency: Optimal use of scarce resources to minimize waste.
- Equity: Fairness and justice in the distribution of resources.
- Economic well-being: Satisfaction derived from an economic situation.
- Sustainability: Maintaining an activity or policy over time.
- Change: A continuous process in economics and in the real world.
- Interdependence: Economic decision-makers rely on and interact with each other.
- Intervention: Typically government involvement in a market.
- Opportunity Cost: The value of the next best alternative that was forgone when making an economic decision.
- Free Good: A good that isn't scarce and has zero opportunity cost.
- Economic Good: A scarce resource, naturally produced or man-made, with an opportunity cost.
Production Possibility Curve (PPC)
- PPC: A model illustrating the maximum combination of two goods a fully-employed, efficient economy can produce, given limited resources and fixed technology. Points on the curve represent production possibilities.
- Economic Growth: An increase in the output of goods and services in an economy over a period, often measured by GDP.
- Economic Development: Broad improvement in living standards and quality of life, often measured by factors beyond GDP.
Economic Theories
- Positive economics: Focuses on factual analysis of economic issues.
- Normative economics: Incorporates value judgments and opinions in analyzing economic issues.
Economic Modeling Assumptions
- Ceteris paribus: Holding all other variables constant.
- Rational economic decision-making: Individuals act in their self-interest.
Macroeconomic Measures
- GDP (Gross Domestic Product): The total market value of all final goods and services produced within a country's borders in a given year.
Elasticity
-
Price Elasticity of Demand (PED): Measures responsiveness of quantity demanded to price changes.
-
Inelastic Demand (PED): A change in price leads to a proportionally smaller change in quantity demanded (0 < PED < 1).
-
Unitary Elastic Demand (PED): A change in price leads to an equal change in quantity demanded (PED = 1).
-
Perfectly Inelastic Demand (PED = 0): A vertical demand curve.
-
Income Elasticity of Demand: Measures the responsiveness of demand to changes in income.
-
Price Elasticity of Supply (PES): Measures responsiveness of quantity supplied to price changes.
Market Efficiency
- Allocative Efficiency: Resource allocation leading to the optimal combination and quantity of goods and services preferred by society. It occurs when an equilibrium and Pareto optimum are reached, maximizing social welfare.
Supply and Demand
- Demand: The quantity of a good or service consumers are willing and able to buy at a given price and time.
- Law of Demand: Higher prices lead to lower quantities demanded, vice versa, ceteris paribus.
- Supply: The quantity of a good or service producers are willing and able to offer at a given price and time.
- Law of Supply: Higher prices lead to higher quantities suppliers offer, vice versa, ceteris paribus.
Market Equilibrium and Mechanisms
- Price Mechanism: System where supply and demand forces determine product prices.
- Resource allocation function: signaling mechanism directs resources to where they are most valued in the economy
- Rationing function: Allocates goods to those who are willing and able to pay.
- Equilibrium: A state of balance where there's no tendency for change in price or quantity.
Goods and Taxes
- Primary commodities: Goods deriving directly from natural resources (e.g., agricultural products).
- Manufactured goods: Products made from raw materials.
- Indirect tax: Taxes levied on consumer expenditure.
- Subsidy: Financial aid from the government to reduce production costs.
Consumer and Producer Surplus
- Consumer surplus: Difference between what consumers are willing to pay and actual price.
- Producer surplus: Difference between price received and price producers are willing to accept.
Factors Influencing Elasticities
- Determinants of PED: Substitutes, proportion of income, necessity/luxury, addictive nature, time to respond.
- Determinants of PES: Production lag, inventory/stocks, spare capacity, substitutability of factors of production, time period
Price Controls
- Price Ceiling: A legal maximum price set below the equilibrium price, often intended to make goods more affordable.
- Price Floor: A legal minimum price set above the equilibrium price, often to support producers’ income.
Market Failure
- Market failure: A situation where free markets fail to achieve socially desirable outcomes.
