Understanding the Supply Demand Model

The demand for an item can depend on various factors as I mentioned earlier. There is a terminology that we use to describe the willingness of a buyer to spend a certain dollar amount on the demand of his choice. The price of a good has a correlation with the quantity that is being demanded. For example, if a Starbucks cup of coffee costs $2, 100 buyers will spend money on coffee every morning, but if the price of the coffee goes up to $4, then only 45 buyers will be willing to purchase that cup of coffee every morning. Not only can the price for the cup of coffee can go up, but it can also go down, another example would be if the price drops to $1, the demand for coffee will now come from 160 buyers versus the 100 buyers that were willing to pay $2 for their coffee; this would be classified as

* From the scenario for Katrina’s Candies, examine the key factors affecting the demand for and the supply of a good in general and Katrina’s Candies specifically. Distinguish between a change in demand and a change in the quantity demanded (movement along the demand curve).

The first factor is the availability of substitute goods, which are goods that can be utilized instead of the original good. If there is a substitute good available, the demand is likely to change more because people can buy different products. On the contrary, if an item has few substitute goods, it may not gain or lose customers. In Canada, Nike shoes have lots of substitute goods like Adidas

Fill in the matrix below and describe how changes in price or quantity of the goods and services affect either supply or demand and the equilibrium price. Use the graphs from your book and the Tomlinson video tutorials as a tool to help you answer questions about the changes in price and quantity

Supply and demand lies in the heart and soul of economics. The concept is perhaps the single most driving force in an economy, specifically a capitalist economy. Supply and demand is based on two concepts: The law of demand and the law of supply. The law of demand states that the demand of a product rises as its price falls, therefore the demand of a product falls as its price rises. A good example of this occurs in grocery stores. If the price of a case of Coca-cola drops from $6.99 to $2.99 the demand for the product will rise because more people are willing to pay $2.99 rather than $6.99. Not only will typical consumer of Coca-cola purchase more but consumers who are not normally willing to pay $6.99 will make the purchase. Substitution also plays a role in the equation. Substitution occurs when consumers substitute one good for another based on price levels. In the Coca-cola scenario, some Pepsi drinkers will purchase the Coca-cola given the case of Pepsi is price higher.

a.) Draw and properly label the demand and supply graphs (this means you must label the axes and any lines you include on the graph).

The market price of a good is determined by both the supply and demand for it. In the world today supply and demand is perhaps one of the most fundamental principles that exists for economics and the backbone of a market economy. Supply is represented by how much the market can offer. The quantity supplied refers to the amount of a certain good that producers are willing to supply for a certain demand price. What determines this interconnection is how much of a good or service is supplied to the market or otherwise known as the supply relationship or supply schedule which is graphically represented by the supply curve. In demand the schedule is depicted graphically as the demand curve which represents the

Demand for the product is determined by many factors, like pricing, quality, advertising and distribution.

Normal products are categorized as products whose value is lower than prestigious products, they both assume a role in the market as they are targeted to different market segments. Demand curves differ as both products may be perceived differently, typically normal products are perceived as lower quality contrary to prestigious products whose customers perceive them as higher quality products. Ultimately, they differ in the perception of the customer as each product is categorized according to their price, and higher priced products may be perceived as better. An example could be represented by two different vehicle manufacturers; Honda, and BMW, Honda is a low priced vehicle known for reliability fuel efficiency, etc.… BMW are known for their luxury, and price. Here their demand may differ as they both have different target markets. Perhaps if Honda decided to raise their price, they would more than likely lose profit, but if BMW was to lower their price, their demand would potentially increase. These changes are known as demand shifts here a firm identifies the traits of each shift, and can identify the relationship in demand. Moreover, marketers can estimate their product demand. This is done by one;

The demand curve shows what happens to the quantity demanded of a good when its price varies, holding constant all the other variables that influence buyers. When one or more of these other variables changes, the demand curve shifts leading to an increase or decrease in demand. The table below lists all the variables that influence how much consumers choose to buy cigarettes.4

The demand curve represents how much consumers will purchase at a given price. Economists use jargon describing the response such as “price decreases then

On the other hand the quantity demanded will also increase. Regardless of the price and assuming that the phone meets the need of its market properly the increase in income would mean an increase in disposable income which can be used to purchase the more phones of the A-Phone brand. The graph will thus show an increase in demand with a constant price regardless of how high or low the price may be because the market will be comfortable to purchase the A-phone at any price.

The following graph demonstrate the demand curve of how many items of a product or service a consumer would like to purchase at different prices. Now by having the product at a lower price, the more a consumer is likely to buy. For that same reason it can be concluded that the price is one major factor of the product demand.

Supply and demand is an economic concept or principle that is paramount to illustrating the very close relationship existent between sellers, products, prices, and consumers. As explained by Mankiw, “supply and demand are the forces that make market economies work” (Mankiw, 2014, p. 65). This theory describes the unique way in which consumers and sellers interact. This theory incorporates important ideas such as; quantity demanded and supplied, the laws of demand and supply, demand curves, elasticity, equilibrium, and equilibrium price.

Supply curve shows the relationship between the quantity supplied of a good or service and its price. The law of supply states that while other determinants remain the same (cetris peribus), the price for services or goods increase, quantity supplied for the services and goods will increase, conversely, the price for services and goods decrease, quantity supplied for the
