Study Notes

Understanding Demand and Supply

Economic agents, including firms, specialize in production based on comparative advantage.
The terms of exchange between producers and consumers are determined through market interactions.
Markets exist for most economic goods and services, forming the core of economic activity.

Demand in Microeconomics

Demand faced by firms is influenced by:
- Total industry demand, including consumer numbers and their market power.
- Industry structure and the number of producers.
Individual demand reflects the quantity of goods or services desired by single agents based on prices.

Law of Demand

Quantity demanded inversely relates to price, maintaining ceteris paribus conditions.
The demand curve typically slopes downward due to:
- Substitution Effect: Consumers replace expensive items with cheaper alternatives.
- Income Effect: Changes in price affect consumers' purchasing power.
Examples of demand equations include:
- Linear Demand Function: QxD = a + bPx + θ
- Iso-Elastic Demand: QxD = APxα.

Factors Influencing Demand

Demand fluctuations can result from:
- Changes in consumer preferences, income levels, and prices of related goods.

Demand Curve Dynamics

Firm-specific demand curves depend on:
- Market size and the organizational structure of the industry.
Firms categorized as:
- Price Takers in perfect competition.
- Price Setters in monopoly or monopolistic competition.

Distinctions in Demand Concepts

Change in quantity demanded versus change in demand has significant implications.
Normal goods versus inferior goods differ in response to income changes.
Gross substitutes and complements are defined based on their relationship with other goods.

Demand Functions

General demand function: QxD = f (Px, PY, M, Θ)
- Indicates responsiveness to price changes, related goods, and consumer income.
Specific derivatives showcase:
- Negative relationship with price of the good (Law of Demand).
- Positive relationship with substitutes and normal goods, negative with complements and inferior goods.

Case Study: Japanese Beer Market

Economic downturn impacted traditional beer sales negatively for major breweries.
Declining incomes and beer tax attributed to reduced domestic sales.
Competitor Asahi gained market share despite the overall decline, indicating resilience or different demand factors.

Law of Supply

Quantity supplied relates directly to goods' prices under constant conditions.
Factors influencing supply include:
- Production costs, availability of substitutes and complements, technological advancements, and taxation.

Market Equilibrium

Excess demand calculated by: ED = D(Px, Py, M, Θ) - S(Px, Pz, Cp, ∆).
Auctioneer mechanisms facilitate price adjustments to counterbalance demand and supply discrepancies.
