Chapter 7- Demand and Supply. Demand: Definition. The amount of a good or service that consumers are able and willing to buy at various possible prices during a specified time period. The price at which the amount producers are willing to supply is equal to the amount. Are there any examples of products that have such zero price elasticity of demand? Is inelastic so that they can turn consumer surplus into producer surplus! Producers often take advantage of consumer surplus when setting prices. If a business can identify groups of consumers within their market who are willing.
Supply, Demand, and the Invisible Hand • • • • • • Change Supply! • • A change in the overall quantity supplied can occur because of changes in any of the following areas: • Capacity and technology • Cost structure • Prices of substitutes and complements • Perceptions of future prices Capacity and Technology From time to time you may have heard that there is “too much capacity” in an industry. This has been the case in the telecommunications industry in the first years of the 2000s. So much fiber optic cable, so many cellular systems, and so many factories for making telecommunications equipment were put in place in the 1990s that the industry's ability to supply telecommunications services and equipment has outstripped demand.
When overcapacity occurs in an industry, the entire supply of that industry's product increases. When that happens, producers are willing to deliver a greater quantity of goods and services for the same price. Why shouldn't they? They have more capacity than they can use, so they may as well use as much as they can, at any price (well, almost any price). An increase in supply also occurs if there are numerous producers for a product or service. Some observers of the business scene have argued that the telecommunications industry has too many providers, which contributed to the overcapacity.
Indeed, a large number of producers in any industry adds capacity, which causes supply to increase. Finally, technological developments can lead to a shift in supply. Returning to our beef example, suppose the industry develops better methods of feeding cattle or controlling disease.
Or suppose more efficient processing and shipping technologies come along. Under those circumstances, the quantity supplied for a given price would increase. The converse of these factors also holds true. Too little capacity, a paucity of producers, or lack of technological innovation will decrease the supply. Cost Structure If the cost of any factor of production—labor, raw materials, equipment—decreases, the quantity that producers are willing (and able) to supply at a given price increases. Producers with lower costs will always be able to supply more of a product at a given price than those with higher costs. Therefore, a decrease in producers' costs will increase the supply.

Conversely, if production costs increase, the quantity supplied at a given price will decrease. Higher costs mean that producers will have to produce less to be able sell a product at a given price. If you're thinking, “Why don't they just raise their prices when their costs go up?” you're asking a good question. Essentially, consumers will resist the higher prices, and may move to substitutes, do without the product, or buy from a more efficient producer. Prices of Substitutes and Complements. EconoTalk Substitutes in production are two or more products or services that a producer can make or deliver in place of one another. For instance, a farmer may be able to grow either corn or soybeans, a manufacturer may be able to produce either men's or women's clothing, or an arena may be able to host either sports events or concerts.
