Chapter 2 Application of Demand and Supply Market-is an interaction between buyers and sellers of trading or exchange. https: //ww w.yell owpa ges.c a/tips /3- thrifty -tips- for- grocer y- shopp ing/ Goods market-is the most common type of market because it is where we buy consumers goods. Labor market-is where workers offer services and look for jobs, where employers look for workers to hire. https://w ww.philsta r.com/hea dlines/201 9/01/02/1 881616/do le-most- unemploye d-are- educated Financial market-it includes the stock market where securities of corporations are traded. https://ww w.worldfina nce.com/m arkets/the- philippines- closes- financial- markets- due-to-the- coronavirus Examples of Financial market Interbank-arrange or operating between banks Stock Exchange-securities are bought and sold Money Market-the trade in short-term loans between banks and other financial institutions Bond Market-a marketplace where investors buy debt securities that are brought to the market Foreign Exchange-exchanging the currency of one country for another at prevailing exchange rates Demand-is the willingness of a consumer to buy a commodity at a given price. https://www.tes.com/lessons/zGiPKu PEAmByJw/goods-and-services Income effect-is felt when a change in the price of a good changes consumer’s real income or purchasing power, which is the capacity to buy with a given income. -more money, more goods to buy Substitution effect-is felt when a change in the price of a good changes demand due to alternative consumption of substitute goods. -buying cheaper goods than expensive ones The Law of Demand As the price increases, the quantity demanded for that product decreases. The low price of goods motivates the consumer to buy more. When the price increases, the quantity demanded for the good decreases. Ceteris paribus-means all related variables except those that are being studied at the moment are held constant. Non-Price Determinants of Demand The following can cause an upward or downward change in the entire demand for the product and this change is referred to as a shift of the demand curve.

The high price of the good serves as motivation for the seller to offer more for sale. Thus, when price increases, the quantity supplied of the good increases since the seller take this as an opportunity to increase his income. Non-Price Determinants The following can cause an upward or downward change in the entire supply of the product, and this change is referred to as a shift of the supply curve. Cost of production Technology Availability of raw materials and resources Supply Function A mathematical expression that expresses the relationship of quantity supplied (Qs) and price (P) Supply Function Qs = -126+6P Qs – quantity supplied US (-126) – unwanted supply 6P - change in the supply P - price Supply Schedule a table showing the direct relationship between price and quantity supplied Market Supply Schedule for Sweet Potato (kilo) Qs = -126 + 6P POINT P Q (Php) (piece) A 30.00 B 29.00 C 27.00 D 25.00 E 23.00 F 21.00 Qs = -126 + 6P Qs= -126 + 6 (30) = -126 + 180 = 54 Qs= -126 + 6 (29) = -126 + 174 = 48 Market Supply Schedule for Sweet Potato (kilo) POINT P Q (Php) (piece) A 30.00 54 B 29.00 48 C 27.00 36 D 25.00 24 E 23.00 12 F 21.00 0 Market Supply Curve for Sweet Potato (kilo) P 30 25 20 15 10 5 0 5 10 15 20 25 30 35 40 45 50 Qs Shifts in the Supply Curve Use of technology Subsidy on the expenditures of the producers Increase in the number of sellers Increase in the price of related product Shifts in the Supply Curve Calamities Decrease in the number of sellers Lack of subsidy Lack of technology Low prices of commodities Equilibrium It is a state of balance when demand is equal to supply. The equality means that the quantity that sellers are willing to sell is also the quantity that buyers are willing to buy for a price. It is an implicit agreement between how much buyers and sellers are willing to transact. Equilibrium price-price at which demand and supply are equal. Equilibrium quantity-The quantity of products that both buyers and sellers agree to transact at a specified price.

Prices of real estate and construction materials are always on rise. Housing supply is less than the existing demand. There is obviously an excess of demand compared to the supply of housing. Other people are borrowing money from financial institutions with interest. Others are renting from homeowners for a monthly fee. Rent Control Law is a type of government intervention that sets a mandatory ceiling on rental fee. Market Structures Market Structures Competition-is rivalry among various sellers in the market. 1.Perfect Competition-it implies an ideal situation for the buyers and sellers. *there are so many buyers and sellers that each has a negligible impact on market price. *homogeneous product is sold by sellers *perfect mobility of resources *there is perfect knowledge of economic agents of market conditions *market price and quantity of output are determined exclusively by forces of demand and supply https://www.slideshare.net/MacVasquez/market-structure- 64967734 Market Structures 2. Imperfect Competition Monopoly-it exists when a single firm that sells in that market has no close substitutes. Ex. Meralco (distributor of electricity in Greater Metro Manila), NAPOCOR (government produced electricity) *there is a need for stricter government law Market Structures 2. Imperfect Competition Oligopoly-it is a market dominated by a small number of strategically interacting firms. Ex. Oil firms (OPEC) Market Structures 2. Imperfect Competition Monopolistic Competition-wherein products are differentiated and entry and exit are easy. Ex. Toyota, Honda, Mercedes Benz Fast food chains http://osyfi315.kip.net.ru/4230 34- 142f561253b345ff5e5d66cc98c 8087f/532126_556925 Application of Demand and Supply to Philippine Economic Problems A.
