Explain the difference between a change in demand and a change in quantity demanded. Be sure to specify what causes each to change and how they differ when graphed.
A change in demand results from a change in one or more of the determinants of demand:prices of related goods (substitutes and complements), income of buyers, number of buyers, expectations of future price, and preferences of buyers. When demand changes the entire demand curve shifts to the right (an increase in demand) or to the left (a decrease in demand). A change in quantity demanded results from a change in a good's own price and is shown on a graph by a movement along a given demand curve.
Explain the difference between a change in supply and a change in quantity supplied. Be sure to state what causes each to change and how they differ when graphed.
A change in supply results from a change in one or more of the determinants of supply:prices of relevant resources, prices of other goods, technology, number of sellers, expectations of future price, taxes and subsidies, and government restrictions. When supply changes the entire supply curve shifts to the right (an increase in supply) or to the left (a decrease in supply). A change in quantity supplied results from a change in a good's own price and is shown on a graph by a movement along a supply curve.
What is the law of diminishing marginal utility?
Additional units provide less and less additional utility over a short time period.
If price is on the vertical axis and quantity demanded is on the horizontal axis, why is a demand curve downward sloping (left to right)?
Because a demand curve is the graphical representation of the law of demand, which specifies an inverse relationship between price and quantity demanded, ceteris paribus.
what is a consumer's surplus
Consumer Surplus is the difference between the price that consumers pay and the price that they are willing to pay.
Labor is a resource that is necessary to produce many goods. "If the price of labor falls," says the economist, "the prices of goods will soon follow." How does this work?
If the price of labor falls, the supply of goods rises, and the prices of those goods fall.
what is a neutral good
Neutral goods are necessities. Income does not affect the quantity demand for a normal good.
Describe one of the two reasons given in the textbook to help explain why price and quantity demanded are inversely related.
One reason that price and quantity demanded are inversely related is that people substitute lower priced goods for higher priced goods. As the price of one good rises, people will tend to shift away from consuming that good (reducing the quantity demanded), toward one that is relatively lower priced. The second reason that helps to explain this inverse relationship is the law of diminishing marginal utility. The law of diminishing marginal utility states that the marginal utility of equal successive units consumed tends to decline as more units are consumed. Since people tend to receive more marginal utility from the first unit consumed than from the second unit, it makes logical sense that they would be willing to pay more for the first unit than for successive units. In order to encourage the buyer to purchase more units, the seller must lower the price.
Suppose that the average price of refrigerators has fallen over the past few years, yet the refrigerator companies have offered more and more of them for sale. Does this mean that the supply curve for refrigerators is downward sloping?
The reason that refrigerator prices have fallen is likely a result of a change in one of the determinants of supply. For example, a technological improvement in the production of refrigerators may have occurred. This advance in technology would cause the supply curve for refrigerators to shift to the right, lowering equilibrium price and raising the equilibrium quantity. Since one of the determinants of supply has changed, this is not a case of a movement along a supply curve (and thus does not violate the law of supply).
When Hurricane Katrina hit the Gulf Coast of the United States in 2005 it destroyed 5,000,000 acres of timber. Given that lumber is timber that has been sawed or split into planks and boards, explain in terms of supply and/or demand how the hurricane impacted each of the following markets (be sure to note the expected resulting impact on equilibrium price and quantity): a. Domestic lumber b. Imported lumber c. New home construction
The severe weather would be expected to shift the supply curve for domestic lumber to the left, but would not automatically shift the demand curve. This would result in a higher equilibrium price and a lower equilibrium quantity for domestic lumber. Imported lumber is a substitute for US-grown lumber, therefore the demand curve for imported lumber would be expected to shift to the right. The supply curve for imported lumber would not automatically shift. This would result in a higher equilibrium price and a higher equilibrium quantity for imported lumber. An increase in the price of timber would represent an increase in a resource cost for those who are building new homes. Higher resource costs shift the supply curve for new home construction to the left, but the demand curve would not automatically shift. This would result in a higher equilibrium price and a lower equilibrium quantity for new homes.
At a price above the equilibrium price, there is
a surplus
