Introduction
This lesson is about the concept of demand and supply that we encounter in our daily life, since we are all consumers and not all producers of goods or services. We also should know the effect of the price of goods and services to the demand that consumers are willing to buy. And to discuss the basic concept of demand and supply for the learners will be able to budget their own allowances everyday.
Task
They will explain the concept of demand and supply by graphing and giving an example to each concept.
They will be able to come up with a budget list for their daily needs based from their daily allowance.
Process
BASIC CONCEPT OF DEMAND AND SUPPLY
DEMAND- quantities of a particular goods and services consumers are willing and able to buy from the market at different possible prices
TYPES OF DEMAND
1. CONSUMER GOODS AND PRODUCER GOODS
Consumption goods- directly satisfy our needs
Capital Goods- goods used for production for other goods
2. PERISHABLE AND DURABLE GOODS
Durable goods- products that last for a long time, usually three years and more
Perishable goods- goods that decay/spoil quickly
3. AUTONOMOUS AND DERIVED GOODS
Autonomous goods - the amount of consumption that would take place in an economy if consumers had no income. These goods are often dubbed as “NEEDS” food, water, electricity, etc.
Derived goods- raw materials or other inputs to a process of production
4. INDIVIDUAL’S DEMAND AND MARKET DEMAND
Individual demand- represents the quantity of a good that a single consumer would buy at a specific price point at a specific point in time
Market demand- summation of the demand for a goods/services by all individual
5. FIRM AND INDUSTRY DEMAND
INDUSTRY DEMAND – the total demand for the products of a particular industry
FIRM/ COMPANY DEMAND – Refers to the demand for the products of a particular c company in an industry, an industry consist of different brand names and trademarks.
LAW OF DEMAND- As the price of good increases, quantity demand decreases and as the price decreases, quantity demand increases.
-This describes how price affects CONSUMERS
SUPPLY - goods and services, producers or sellers are willing and able to sell
LAW OF SUPPLY- As the price increases, the supply increases and as the price decreases, the supply decreases
This describes how price affects PRODUCERS
NON-PRICE DETERMINANTS OF SUPPLY
1) NUMBER OF SELLERS – The more sellers, the more quantity supplied for a particular good or service.
2) TECHNOLOGY - a modern and advance technology will result to mass production, while a traditional method will brings about inadequate output.
3) COST OF PRODUCTION – the higher the cost of producing a particular goods, the lesser is the amount of good available for sale
4) TAXES AND SUBSIDIES – the higher the tax, the lesser will be the amount available for re- investment by the firm that creates less outputs.
SUBSIDIES are grants or aids extended by the government to help ease the production activities of producers. Therefore, the more subsidies provided by the government, the more outputs will be produced.
EXEPTIONS TO THE LAW OF SUPPLY
1) EXEPTIONS REGARDING FUTURE PRICE – When the sellers expect the prices to rise in the future then they may adopt, wait and watch policy and withhold their supply of goods.
2) FARM PRODUCE – such product may not obey the law of supply as they may not react to changes in prices due to heavy dependency to weather conditions
3) PERISHABLE COMMODITIES – Certain commodities have very short shelf life and they need to be made available in the market before they perish..
4). OUT OF FASHION GOODS – there are certain goods that are out of fashion and no longer in vogue, sellers lower it’s price to clear these goods
5) ECONOMIC SLOWDOWN – During the low economic phases, the sellers may not have advantage of high prices and hence during such tough times goods are sold even when they do not witness price rise in order to recover their costs. Law of supply is not applicable in this case.
6) CHANGE IN BUSINESS – changing business will cause the seller to sell his current goods to lower price to clear them off.
7) IMMEDIATE REQUIREMENT OF FUNDS – there are times that the seller is in immediate need of funds , so he will supply the goods in the market even at lower prices.
8) SUPPLY OF LABOUR – The workers are interested in high wages till a certain point, once that point is achieved they may like to devote their time to leisure activities. So after a particular point, the workers may no longer interested in higher wages.
-workers may put in less hours of work even if more wages are offered to them (supply of labor is inversely related to wages)
CHANGE IN QUANTITY SUPPY VS. CHANGE IN SUPPLY
CHANGE IN QUANTITY SUPPLY
-The change in quantity supply is brought about by changes in prices, it is the movement of point within the same supply curve.

A) Explain the types of Demand on your own words and give example on each type.
B) Explain the law of demand and law of supply using a graph.
Activity 2
Based from your daily allowance, list your daily expenses showing that you are able to save one percent of your allowance.
