Study Notes

Demand Overview

Economic agents specialize in production based on comparative advantage.
The terms of exchange for goods and services are shaped by consumer and producer interactions in the market.
Understanding the concept of "market" is essential; not all economic goods or services have a market.

Demand Faced by Firms

Demand depends on the total industry demand and the market power of consumers.
Individual demand is influenced by the amount an individual wishes to consume at a given price.
Demand arises from consumers' willingness and ability to purchase goods.

Law of Demand

Quantity demanded inversely relates to price when other factors remain constant.
The demand curve is negatively sloped due to the substitution effect and income effect.
Linear demand function can be represented as (QxD = a + bPx + θ).

Factors Affecting Demand

Factors influencing demand include consumer preferences, income levels, prices of related goods, and market trends.
Gross substitutes and complements affect demand elasticity differently.

Demand Curve for Firms

The demand faced by a firm is influenced by market size and industry organization.
In perfect competition, firms act as price takers; in monopolies or oligopolies, firms act as price setters.

Key Concepts in Demand

Distinctions between "change in quantity demanded" and "change in demand" are critical.
Normal goods see an increase in demand with rising income, while inferior goods have the opposite effect.

Demand Function

The general demand function can be represented as (QxD = f(Px, PY, M, Θ)).
Price changes directly affect quantity demanded, indicating relationships with substitutes and complements.

Real-World Example: Japanese Beer Market

Japanese breweries faced challenges during a recession due to decreased consumer income and increased beer taxes.
Major brands like Kirin and Sapporo suffered declines while competitors like Asahi experienced growth, likely due to better adaptability to market conditions.

Law of Supply

Quantity supplied of a good is directly related to its price, other things being equal.
Factors affecting supply include production costs, technology, alternatives, and taxation types like excise taxes.

Market Equilibrium

Excess demand can be calculated as ( ED = D(Px, Py, M, Θ) - S(Px, Pz, Cp, ∆) ).
Price adjustments in the market help resolve excess demand situations, managed by what can be termed an "auctioneer."
