In other words, when income increases, the demand curve shifts to the left. Other factors that shift demand curves Income is not the only factor that causes a shift in demand. Other things that change demand include tastes and preferences, the composition or size of the population, the prices of related goods, and even expectations.
A change in any one of the underlying factors that determine what quantity people are willing to buy at a given price will cause a shift in demand. Graphically, the new demand curve lies either to the right, an increase, or to the left, a decrease, of the original demand curve.
Supply and demand
Changing tastes or preferences From tothe per-person consumption of chicken by Americans rose from 48 pounds per year to 85 pounds per year, and consumption of beef fell from 77 pounds per year to 54 pounds per year, according to the U. Changes like these are largely due to movements in taste, which change the quantity of a good demanded at every price—that is, they shift the demand curve for that good, rightward for chicken and leftward for beef.
Changes in the composition of the population The proportion of elderly citizens in the United States population is rising. It rose from 9. A society with relatively more children, like the United States in the s, will have greater demand for goods and services like tricycles and day care facilities. A society with relatively more elderly persons, as the United States is projected to have byhas a higher demand for nursing homes and hearing aids.
Similarly, changes in the size of the population can affect the demand for housing and many other goods.
Each of these changes in demand will be shown as a shift in the demand curve. Related goods The demand for a product can also be affected by changes in the prices of related goods such as substitutes or complements.

A substitute is a good or service that can be used in place of another good or service. As electronic resources, like this one, become more available, you would expect to see a decrease in demand for traditional printed books.
A lower price for a substitute decreases demand for the other product. Supply and Price Supply is the amount of goods or service you provide at different prices. You're willing to supply more of your items when you can sell them at a higher price than at a lower price.

However, there comes a point where if the price becomes too high, it negatively affects your sales. At this point, you must either lower your price to attract new buyers or improve your product enough to justify the higher price.
Supply and the Marketplace Your costs increase when labor and materials costs rise.
To compensate, you can cut back on production to avoid raising your prices. On the other side, technological improvements can reduce your costs so you can increase your supply without increasing the price. Your competitors also have a direct impact on the available marketplace supply. When the selling price is high, it attracts new competitors wishing to enter the market.

If they wish to purchase less than is available at the prevailing price, suppliers will bid prices down. Thus, there is a tendency to move toward the equilibrium price. That tendency is known as the market mechanism, and the resulting balance between supply and demand is called a market equilibrium.
As the price rises, the quantity offered usually increases, and the willingness of consumers to buy a good normally declines, but those changes are not necessarily proportional. The measure of the responsiveness of supply and demand to changes in price is called the price elasticity of supply or demand, calculated as the ratio of the percentage change in quantity supplied or demanded to the percentage change in price.
Thus, if the price of a commodity decreases by 10 percent and sales of the commodity consequently increase by 20 percent, then the price elasticity of demand for that commodity is said to be 2. The demand for products that have readily available substitutes is likely to be elastic, which means that it will be more responsive to changes in the price of the product.
That is because consumers can easily replace the good with another if its price rises.
