Substitute good - Wikipedia
Definition of substitute goods - two alternative goods that could be used demand for one good in relation to a change in the price of another. Substitute goods are those goods which can be used in place of one another for It must be noted that a demand curve shows the relationship between the. In animal models Ca salts reduced both haem- and non-haem-Fe absorption, the amount of Ca administered rather than the Ca:Fe molar ratio; dairy products whether the inverse relationship between consumption of dairy products and is due entirely to increased Ca intake; substitution of milk proteins for meat may.
Economics classifies goods on the basis of various characteristics, viz. These goods have various price elasticity demands. Price elasticity measures the degree of variance in the quantity demanded, in response to the change in price of a product. Price elasticity of any product is influenced by many factors such as technology, fashion, industry, economic conditions of the nation, rate of inflation, resource availability, etc.
Cross price elasticity measures the impact on the demand of a good in response to the change in price of any other good. This MarketingWit article talks in depth about the complementary and substitute goods, the difference between them, and their cross price elasticity.
What are Substitute Goods? Substitute goods refer to alternative goods to any particular product, that can be used as a replacement for the original product or good. Thus, it implies that their price elasticity is interrelated.
Price Elasticity of Substitute Goods Price elasticity measures the degree of relativity of change in demand of a product in response to change in price of the product. Price elasticity of a substitute good is cross elastic, i. If a certain product enjoys monopoly in the market, it is less likely to have any substitutes.

Thus, the degree of substitution may differ, too. These goods can be further classified into weak substitutes or perfect substitutes, i. Example Suppose 'R' and 'S' are substitute goods for each other.
Price of 'R' increases, the demand for it will reduce. However, consumers will prefer to buy product 'S', hence, demand for 'S' will increase at the similar price level. This proves that there is an inverse relationship between demand of substitute goods. Impact of Market Conditions on Substitute Goods The psychology of consumers keeps on changing according to fashion trends, technology, brand name, etc.
For example, cotton was the reigning fabric till some time ago; however, with the advent of synthetic fibers, cotton took a back seat. These synthetic fibers are available at lower cost.
Hence, the market for cotton was largely taken over by them. However, these substitutes cannot furnish the same comfort as cotton; hence, many do not prefer to use fabrics made of artificial fibers.
Another powerful impact is that of fashion. Many consumers prefer to buy those products which their favorite celebrities endorse. Hence, demand for substitutes are also affected by other parameters. There are some consumers who are brand loyal, and will not like to experiment with other substitutes, even if the substitute is of the same or a higher quality.
Again, degree of elasticity is impacted in this case. What are Complementary Goods? As the name suggests, complementary goods are those goods that are used along with each other, or the use of one product complements the another.
For example, if price of a complementary good say, sugar increases, then demand for given commodity say, tea will fall as it will be relatively costlier to use both the goods together. Let us understand this through Fig. As seen in the given diagram, price of sugar complementary good is shown on the Y-axis and demand for tea given commodity on the X-axis. It must be noted that a demand curve shows the relationship between the quantity demanded of a given commodity and its price.

Demand is not affected by Change in Price of Unrelated Goods: Demand for a commodity is affected by change in price of only related goods substitute goods and complementary goods. Any change in the price of unrelated goods does not affect the demand for a given commodity. Unrelated goods refer to those goods which are not linked with the demand for a given commodity.
For example, there will be no change in the demand for tea with a change in the price of Pen.
Cross demand refers to the relationship between the demand of a given commodity and the price of related commodities, other things remaining the same. Cross demand indicates how much quantity of a given commodity will be demanded at different prices of a related commodity substitute or complementary. It can be expressed as: Cross demand is positive in case of substitute goods as demand for the given commodity varies directly with the prices of substitute goods.
Cross demand is negative in case of complementary goods as demand for the given commodity varies inversely with the prices of complementary goods. Cross Price Effect on Demand Curve: Cross Price Effect refers to effect on the demand for a given commodity due to a change in the price of a related commodity.
It means, cross price effect originates from substitute goods and complementary goods. Let us understand the effect on the demand curve of a given commodity when there is change in the prices of substitute and complementary goods.
