How Consumers Choose Substitutes

Definition

A subst♛itute product can be used to replace another, since it typically has the same form, f൲it, and function as a preferred item.

What Is a Substitute?

A substitute is a product or service that consumers ca🐠n use to replace another item. Substitutes provide more choices for consumers and play an important role in a competitive marketplace.

Key Takeaways

  • In economics, products are substitutes if the demand for one product increases when the price of the other goes up.
  • Substitutes help create competition and lower prices in the marketplace.
  • A generic product is commonly a substitute for a brand-name item.

Consumer Demand

Substitutes occur when at least two products can be used for the same purpose, such as an iPhone vs. an Android phone. For a product to be a substitute for ⛄another, it must share a particular relationship with that good. Those relationships can be close, like one brand of coffee with another, or somewhat further apart, such as coffee and tea.

There is a relationship between the 澳洲幸运5开奖号码历史查询:demand schedules of substitute products. If the price of a product goes up, the demand for a substitute will tend to increase. This is because people will prefer a lower-cost substitute to a higher-cost item. For example, if the price of coffee increases, the demand for tea may also increase as consumers switch from coffee to tea to maintain their budgets.

Conversely, when a good's price decreases, the demand for its substitute may also decrease. In economic language, X and Y are substitutes if demand for X increases when the cost of Y increases, or if there is positive 澳洲幸运5开奖号码历史查询:cross elasticity of demand.

Examples of Substitute Goods

  • A dollar bill for four quarters
  • Coke vs. Pepsi
  • Premium vs. regular gasoline
  • Butter and margarine
  • Tea and coffee
  • Apples and oranges
  • Riding a bike versus driving a car
  • E-books and print books

Perfect Substitutes

A perfect substitute can be used the same way as the good or service it replaces. The utility of the product or service is identical. For example, a one-dollar bill is a perfect substitute for another𝓀 dollar bill. Butter from two different producers can be considered an exact substitute.

However, a bike and a car are not perfect substitutes, but they are similar enough for people to use tﷺhem for transportation. Although an imperfect substitute may be replaceable, consumers see degrees of difference. Consumers and economists may disagre🧸e on a perfect vs. imperfect substitute. A consumer may choose Coke over Pepsi—perhaps because of taste—even if the price of Coke goes up. They perceive a difference between soda brands, even if economists consider them perfect substitutes.

Less perfect substitutes are sometimes classified as gross or net substitutes by factoring in utility. A gross substitute is one in which demand for X increases when the price of Y increases. Nꦗet substitutes are those in which demand for X inc✅reases when the cost of Y increases, and the utility derived from the substitute remains constant.

Important

澳洲幸运5开奖号码历史查询:Price elasticity of demand measures the change in the demand for a product when its price changes. If no substitutes exist, demand remains constant when the price increases, making it inelastic. However, 𒁏when substitutes are available, the demand for those products will be more elastic.

Competition

In perfect competition, perfect substitutes are sometimes conceived as nearly indistinguishable goods sold by different firms. Gasoline from a gas station on one corner may be virtually indistinguishable from gasoline sold by another gas station on the opposite corner. When prices increase at one station, people will choose the chea♓per option.

In monopolistic competition, companies are not 澳洲幸运5开奖号码历史查询:price-takers, meaning demand is not highly sensitive to price. A common example is the difference between the generic and name-branded medicine. The products are nearly indistinguishable chemically, but they are not perfect substitutes due to the utility consumers may get—or believe they get—from purchasing a brand name over a generic drug.

How Do Substitutes Negatively Affect Corporate Profits?

Giving consumers more choices helps generate competition in the market and lower prices as a result. While that may be good for consumers, it may have the opposite effect on companies' bottom line. Alternative products can cut into companies' profitability.

What Is a Generic Product?

A✤ generic brand lacks a recognized name or logo and is typically sold at lower prices than similar brand-named i🧜tems. They are substitutes for more expensive brand-name goods.

How Can Consumers Substitute Original Equipment Manufacturer (OEM) Parts?

OEMs have traditionally manufactured and sold their finished products, like cars, to consumers as brand-name items. However, 澳洲幸运5开奖号码历史查询:bills of materials often include alternate, or generic parts that can replace the standard part if it's destroyed.

The Bottom Line

Consumers often choose substitute products or services if the original item's price increases. Substitutes give consumers more choices and help create competition.
