Study Notes
Microeconomics and Macroeconomics
- Microeconomics examines individual markets, while macroeconomics analyzes the entire economy.
- Microeconomics primarily focuses on consumer and producer decisions, macroeconomics on government actions.
- Microeconomics studies market price changes, macroeconomics overall economic indicators like employment rates, economic growth, and GDP.
The Role of Markets in Allocating Resources
- Resource allocation determines what goods and services are produced, how they are produced, and for whom.
- These "basic economic questions" address fundamental economic problems.
- A market facilitates interaction between producers and consumers of a good or service.
Price Mechanism
- Markets use supply and demand principles to allocate resources.
- The price mechanism involves buying and selling at equilibrium where demand equals supply.
- It resolves the basic economic problem by guiding production towards consumer needs.
- Producers focus on goods in high demand.
Demand
- Demand is the willingness and ability of consumers to purchase at a specific price.
- Individual and market demand signify individual and aggregate consumer intentions.
- The law of demand shows an inverse relationship: higher prices lead to lower quantity demanded, and lower prices lead to higher quantity demanded.
Understanding Graph Terminology
- Extension in demand: Increased quantity demanded due to lower price (other factors constant).
- Contraction in demand: Decreased quantity demanded due to higher price (other factors constant).
- Non-price factors (like advertising) cause shifts in the entire demand curve, not just extensions or contractions.
Key Factors Influencing Demand
- Price is a primary demand influencer.
- Consumer preferences, income, advertising, and substitutes/complements influence demand.
Demand
-
Demand is the desire and ability of consumers to buy a good or service at a given price.
- Individual Demand is one person's demand.
- Market Demand is the total demand across all individuals.
- Law of Demand: As price increases, quantity demanded decreases (ceteris paribus).
- Demand Curve: Illustrates inverse relationship between price and quantity demanded; slopes downward.
-
Changes in Demand (Shift): Occur due to non-price factors, not due to price changes themselves.
- Increase in Demand (Rightward Shift): Higher demand at every price (e.g., increased consumer income).
- Decrease in Demand (Leftward Shift): Lower demand at every price (e.g., rise in substitute good's price).
- Extension in Demand: Movement along the demand curve caused by a price change.
- Contraction in Demand: Movement along the demand curve caused by a price change.
Supply
- Supply is the willingness and ability of producers to sell goods at given prices.
- Law of Supply: As price increases, quantity supplied increases (ceteris paribus).
- Supply Curve: Illustrates the positive relationship between price and quantity supplied; slopes upward.
-
Changes in Supply (Shift): Occur due to non-price factors, not due to price changes themselves.
- Increase in Supply (Rightward Shift): Higher supply at every price (e.g., lower production costs).
- Decrease in Supply (Leftward Shift): Lower supply at every price (e.g., higher production costs).
- Extension in Supply: Movement along the supply curve caused by a price change.
- Contraction in Supply: Movement along the supply curve caused by a price change.
Supply
- Supply is producers' willingness and ability to create goods at different price points.
- The law of supply reflects a positive correlation between price and quantity supplied.
- Factors like production cost, technology, and profitability of alternate products shape the quantity supplied.
Equilibrium Price
- Equilibrium price is where supply and demand intersect, balancing quantities bought and sold.
- Disequilibrium price occurs when supply and demand are not equal.
Price Elasticity of Demand (PED)
- Measures change in quantity demanded versus price change.
- PED = (% Change in Quantity Demanded) / (% Change in Price)
- Elastic demand (PED > 1): Large quantity change in response to small price change; lots of substitutes.
- Inelastic demand (PED < 1): Small quantity change in response to large price change; few substitutes.
- Unit elastic demand (PED = 1): Quantity change matches price change.
Factors Affecting Price Elasticity of Demand
- Number of substitutes: Many substitutes = high elasticity.
- Time period: Longer time = greater elasticity.
- Proportion of income: Necessity = low elasticity; Luxury = high elasticity.
Relationship Between PED and Revenue
- Elastic demand: Lower prices increase revenue.
- Inelastic demand: Higher prices increase revenue.
Price Elasticity of Supply (PES)
- Measures change in quantity supplied versus price change.
- PES = (% Change in Quantity Supplied) / (% Change in Price)
- Elastic supply (PES > 1): Quantity supplied changes much with prices.
- Inelastic supply (PES < 1): Quantity supplied changes little with prices.
Market Economic System
- Prices and production are largely determined by market forces with minimal government intervention.
- Driven by principles of supply and demand.
Market Economic System
- Resources allocated by producers' and consumers' choices.
- Minimal government interference. Decisions based on supply and demand and profit maximization goals.
Features of a Market Economic System
- Private ownership of resources.
- Limited government regulation.
- What to produce – high demand items.
- How to produce – most efficient methods.
- For whom to produce – those who can pay.
- Decisions based on supply, demand, and profit motives.
Advantages
- Competitive variety in goods and services
- Quick response to consumer preferences
- High efficiency due to profit-maximization
- Low entry barriers for businesses
Disadvantages
- Production limited to profitable items; neglecting public or merit goods
- Uneven distribution of goods/services; only those who can afford items benefit.
- Possible creation of monopolies.
- Externalities like pollution are common due to profit-seeking.
Vocabulary
- Public Good: Used by everyone, difficult to charge for (e.g. streetlights).
- Merit Good: Socially desirable but not necessarily demanded at a "fair" price by all (e.g., education).
- Subsidies: Government funding to reduce production costs and prices.
Market Failure
- Market processes fail to efficiently allocate resources.
- Government intervention can sometimes solve market inefficiency (allocative failures)
