Question

Name two related goods you consume which would have a positive cross-price elasticity. What happens to your consumption of the second good if the price of the first good increases?

Short answer

If the price of the first good increases, the consumption of the second good increases.

Step-by-step solution

Identify Related Goods

Two goods are considered related if they can be used in place of one another, like substitutes, or if they are used together, like complements. Examples of related goods include coffee and tea (substitutes) or printers and ink cartridges (complements). In this case, we're focusing on substitute goods, which have a positive cross-price elasticity.

Define Positive Cross-Price Elasticity

Positive cross-price elasticity occurs when an increase in the price of one good leads to an increase in the demand for another good. This typically happens with substitute goods. This implies that if the price of the first good increases, people will buy more of the second good because it becomes relatively cheaper or more desirable.

Apply to Examples

An example of substitute goods that you might consume could be Coke and Pepsi. If the price of Coke increases, consumers are likely to increase their consumption of Pepsi, as it becomes a more attractive alternative by comparison.

Interpretation

Given this relationship, if you are consuming two goods like Coke and Pepsi, when the price of Coke goes up, your consumption of Pepsi will increase. This aligns with the characteristic of positive cross-price elasticity that applies to substitute goods.

Key concepts

Substitute Goods

Substitute goods are products or services that can be used in place of each other. When you have two goods that serve similar needs, they become substitutes. For instance, consider Coke and Pepsi. Both are popular soft drinks and fulfill the need for a refreshing beverage. Hence, they can be interchanged based on preference, price, or availability.
Understanding substitute goods helps consumers make better choices. If the price of one product rises, you can switch to the other, maintaining your satisfaction without overspending. This flexibility is why many businesses watch their competitors' pricing strategies closely.

• Coke and Pepsi: Both are substitutes as they are similar colas.
• Butter and Margarine: Both can be used for cooking or spreading on bread.

Identifying substitute goods can shift your purchasing habits, helping you manage expenses effectively.

Positive Cross-Price Elasticity

Positive cross-price elasticity is a concept that describes the relationship between two substitute goods. It measures how the demand for one product changes when the price of another product changes.
When you have a positive cross-price elasticity, it means that an increase in the price of one good leads to an increase in the demand for its substitute. This happens because the substitute becomes relatively cheaper or more attractive in comparison.
For example:

• If the price of Coke goes up, the demand for Pepsi might go up because people will buy Pepsi instead.
• The availability of substitutes with positive cross-price elasticity ensures that consumers always have alternative options.

Understanding this concept is crucial for both consumers and businesses. Consumers can keep their spending in check, while businesses can strategize on pricing to influence consumer choices.

Related Goods

Related goods are products that have some connection to each other in terms of consumption or use. They can either be substitutes or complements.
Substitute goods, as discussed earlier, are one type of related goods. They allow consumers to swap one product for another when prices shift. This helps in maintaining a balance between consumption preferences and budget constraints.
Another category is complementary goods, which are used together. For example, printers and ink cartridges are complements because you need both to print documents.

• Substitute Goods: Offer consumers flexibility when prices change, like Coke and Pepsi.
• Complementary Goods: Typically purchased together, affecting each other's demand, like printers and ink.

Understanding related goods can improve decision-making in both personal finance and business strategies. By recognizing the links between goods, you optimize purchases and sales, adapting to market changes with ease.
