Supply And Demand

Central Planning Vs. Market (Unplanned)

▪ Centralised - Decisions made by an individual or small group on behalf of a larger group (e.g.

by a government)

▪ Unplanned/Free Market - Individual in private markets decide what products to buy or

produce

Most modern industrial countries are ‘mixed’ where goods and services are allocated by free markets to a

large extent but with regulation

▪ Free markets tend to assign production tasks & consumption benefits more effectively, but

there is a need for regulation as demonstrated by the GFC.

Markets

Buyers and Sellers need trade because most people specialise in a certain are and are not self sufficient.

A 'market is a set of conditions that allows willing & able buyers & sellers to exchange goods and services.

the price is determined by both supply (production costs + other factors) and demand (value to consumer).

The Demand Curve

The Demand Curve is a representation of the relationship between the amount of a particular good or

service that buyers want to purchase in a given period and the price of that goods or service. [2]

Document Summary

Topic 3 - supply and demand: an introduction. Buyers and sellers need trade because most people specialise in a certain are and are not self sufficient. A "market is a set of conditions that allows willing & able buyers & sellers to exchange goods and services. the price is determined by both supply (production costs + other factors) and demand (value to consumer). The demand curve is a representation of the relationship between the amount of a particular good or service that buyers want to purchase in a given period and the price of that goods or service. Assumptions - ceteris paribus, to isolate the relationship between price and demand. Law of demand - demand rises as price falls, causing a downward sloping demand curve. Income effect - a price increase (decrease) reduces (increases) purchasing power/real income, leaving extra income to purchase higher quantities: substitution effect - price increases will cause people to switch to alternatives.
