REPORTING ON

FACTORS THAT AFFECT THE DEMAND CURVE

(January 13, 2009; 4:00 – 5:30 pm)

I. OBJECTIVES:At the end of one hour discussion, the students will be able to:

1. Identify the factors affecting the demand curve. 2. Differentiate the said factors that affect the demand curve.3. Distinguish demand curve through understanding the basic meanings of these

factors.4. Learn its applications to their everyday lives.5. Apply it to the health care in the Philippines after the discussion.6. Integrate Christian values with these factors.

II. MATERIALS USED: Photocopy as visuals (see sample on the next page); Cartolina (objective)

III. LESSON PROPER:

THE FACTORS THAT AFFECT THE DEMAND CURVE

A. OWN PRICE OF THE PRODUCT (meaning the value of things traded in a marketing exchange, a measure of what must be given up in order to take possession or use of something else.)

A HIGHER PRICE of a A LOWER PRICE of aPRODUCT decreases the DEMAND. PRODUCT increases the

DEMAND.

Thus, inverse relation between the product and the quantity being demanded.

1

E.g. If the price of a popular branded T-shirt is Php 100.00, a lot of customers will buy it. But if the price goes high as Php 900.00 for the said item, few will only buy it.

B. AVERAGE INCOME (typical amount of money)

As the average income of people and households increases, the demand for specific goods also increases.

HIGHER INCOMES make commodities relatively cheaper simply because people have more money to buy goods and services.

E.g. Ana’s salary increased up to Php 10,000.00. Now she can buy the latest brand of laptop computer she wanted.

C. POPULATION SIZE AND DEMOGRAPHICS (DEMOGRAPHIC DATA)

DEMOGRAPHY – concerns with the study of human population collectively. Its population, size, composition, and distribution in the area.

POPULATION SIZE – the total number of people who inhabit an area, region, or country, or the number of people in a particular group who inhabit an area.

DEMOGRAPHIC DATA (a.k.a. Demographics) – it is an information that shows the statistics and he characteristics of human population.

As the population increases, more people will use commodities.

2

Remember: an increase in population generally increases the demand for most products, and changes or shifts in population demographics will affect the demand for specific products.

D. PRICES OF RELATED GOODS

o Substitute products are commodities that decrease the use of another product when more of these other products are used. Remember, that they change and move in the opposite direction.

E.g. (1) The price of MRT decreases. (2) Decrease of MRT fare results in increased demand in MR. (3) Increase in demand for MRT results in decrease in demand for aircon buses (substitute products).

o Complementary Products are commodities that decrease the use of another product when less of the other complement is used and vice-versa. Remember that they change in the same direction.

E.g. (1) the price of gasoline increases. (2) Gasoline price increase induces a corresponding decrease in demand for such. (3) Decrease in demand for gasoline also affects a corresponding decrease in demand for cars (complementary product).

E. TASTE or PREFERENCE OF BUYERS An influence buying decisions but it is more difficult to assess. Taste is a very

important factor in buying decisions of consumers.E.g. Andrei prefers branded or signature jeans while Warren likes jeans

bought from the ukay-ukay.

F. OTHER PARTICULAR FACTORSClimate and weather affect the demand for umbrellas and raincoats. Summer

increase the demand for halo-halo and ice cream. Fiestas affect the demand for lechon, pancit and beer. Natural disaster and seasonality also affects the demand curve.

3

E.g. During the summer season, Havainas slippers became a hit to customers of all walks of life.

IV. EVALUATION:1. What is the difference between substitute and complimentary

products?2. How can you apply these factors to Health Care?3. Can you give some other factor/s that is/are not given in our report?4. Why is that the preference or taste of a buyer is seems so important?
