Supply And Demand Of A Good Or Service

Any change that lowers the quantity that buyers wish to purchase at any given price shifts the demand curve to the left.

Have you ever wondered how the goods and services you purchase become available to you, and have you ever wondered how the prices are determined? Even though economics involves many concepts, supply and demand, as well as trade, are among the most important forces in an economy because of their effect on prices, consumer behavior and economic growth.

Supply and demand is a fundamental element of economics; it is the main support system of a market economy. Demand can be interpreted by the quantity of a product or service a consumer is desired to acquire at a given time period. Quantity demanded is the amount of product consumers are willing to purchase at a given price; the relationship between price and quantity demanded is commonly known as the demand relationship. Supply however, accounts for how much a market produces for consumers. The quantity supplied refers to the actual amount of a certain good firms are willing to supply to consumers when receiving a certain price. Having limited resources we all have to

2.) Which curve(s) change and based on the lists in the text of what causes demand and supply to shift what are the causes of theses shifts? D1 changed moving leftward indicating a decrease in demand due to a technological change: a technological setback causes a decrease. This causes price to go down as well as the demand is lower.

Supply is the total amount of a specific good that is available to the consumers. The supply of lobsters depends on the ocean temperature and since the ocean temperature is increasing, lobsters may once again come in a couple more weeks earlier than usual. In 2012, this caused the quantity of lobster to increase significantly, thus the supply curve shifted to the right. The shift caused the equilibrium price to decrease and the quantity to increase. On the other hand, if the ocean temperature is too low, then the lobster production rate is lowered. The supply curve will then shift to the left and cause the equilibrium price to increase and the quantity to decrease. The lobsterman cannot control the supply of lobsters since the production depends on the temperature. Another economic topic that came to my mind is the demand of a product. Demand is a consumer’s willingness to pay a price for a specific good. The demand curve would shift to the right if the price of the lobsters decreases due to mass production and vice

This causes the price and the quantity move in opposite directions in a supply curve shift. Also, if the quantity supplied decreases at any given price the opposite will happen.

When there is a change of one of the factors of supply- like changes in the prices of production inputs like labour or capital; a change in production technology and its associated productivity change; or the amount of competition in a specific product market- there is a corresponding change in the supply curve. For example, if worker productivity improves due to some human capital or technology investment, then the costs of production decrease. This exerts a positive effect on the supply curve shifting it right, where the new market equilibrium is at a higher quantity and a lower price, holding everything else constant. There can also be a negative shift that moves the supply curve to the left, with the resulting market clearing price being higher and quantity lower, ceteris

When quantity supplied do not equal quantity demanded the outcome is either excess supply or excess demand, and a tendency for price to change. As this happen the consumers will increase their quantity demanded, and the movement toward equilibrium caused by excess supply is both the supply and demand sides. When the excess supply occur quantity supplied is greater than quantity demanded. While the reverse of excess demand quantity demanded is greater than quantity supplied. The excess demand pushes prices upwards in decreasing the quantity demanded and increasing the quantity supplied. This movement takes place along both the supply curve and the demand curve.

In addition to the law of demand, the law of supply also serves as the second major resource in studying economics. The law of supply states that with other factors remaining constant, as the price rises, the quantity of the product supplied also rises. Conversely, as the price falls, quantity of the product supplied also falls (Colander, 2006, p 97). The law of supply is refers to how producers can effectively substitute the production of one product for another (Colander, 2006, p.

This is a perfect example of a change in demand; when the demand increases, at the same or even a higher price, more quantity is demanded. In the figure below, a shift to the right in the demand curve signifies an increase in demand.

An example of demand curve shifting. The shift means an increase in demand with consequences for the other variable.

Elasticity of demand represented as “Ed” is defined as a “measure of the response of a consumer to a change in price on the quantity demanded of a good” (McConnell, 2012). Determinants for elasticity of demand would include the substitutability of a good, proportion of a consumer 's income spent on a good, the nature of the necessity of a good and the time a purchase is under consideration by the consumer. Furthermore, elasticity of demand is calculated with this formula:

Figure 2 demonstrate how any change in one of the other determinants causes demand to rise or to fall by shifting the whole curve to the right or the left. Other factors that determinates of demand

Demand is the relationship between price and quantity demanded for a particular good and service in particular circumstances. For each price the demand relationship tells the quantity the buyers want to buy at that corresponding price. The quantity the buyers want to buy at a particular price is called the Quantity Demanded.

Like the law of demand, the law of supply demonstrates the quantities that will be sold at a certain price. But unlike the law of demand, the supply relationship shows an upward slope. This means that the higher the price, the higher the quantity supplied. Producers supply more at a higher price because selling a higher quantity at a higher price increases revenue.
