Introduction

Elasticity of demand is a fundamental concept in economics that measures how responsive the quantity demanded of a good is to changes in its price. In other words, it helps us understand how much the quantity demanded of a good will change when its price changes. In this article, we will explore which of the following goods would most likely be bought in the same quantity even if it doubled in price.

Understanding Elasticity of Demand

Elasticity of demand can be classified into three categories: elastic, inelastic, and unit elastic. Elastic demand occurs when a small change in price leads to a large change in quantity demanded. Inelastic demand occurs when a large change in price leads to a small change in quantity demanded. Unit elastic demand occurs when a change in price leads to a proportional change in quantity demanded.

Analyzing the Options

Let's analyze the options given:

A. Pencils

Pencils are a staple item in most households and offices. They are a necessity for writing and drawing. Even if the price of pencils doubles, people will still buy them in the same quantity because they are essential for their daily activities. The demand for pencils is inelastic because people will not reduce their consumption of pencils even if the price increases.

B. Notebooks

Notebooks are also a common item in most households and offices. They are used for writing, note-taking, and drawing. However, unlike pencils, notebooks are not as essential for daily activities. If the price of notebooks doubles, people may reduce their consumption of notebooks or look for cheaper alternatives. The demand for notebooks is elastic because people may change their behavior in response to a price increase.

C. Electricity

Electricity is a necessity for most households and businesses. It is used for lighting, heating, cooling, and powering electronic devices. Even if the price of electricity doubles, people will still use it in the same quantity because it is essential for their daily activities. The demand for electricity is inelastic because people will not reduce their consumption of electricity even if the price increases.

D. J.Crew Sweaters

J.Crew sweaters are a luxury item that people buy for fashion and comfort. If the price of J.Crew sweaters doubles, people may reduce their consumption of sweaters or look for cheaper alternatives. The demand for J.Crew sweaters is elastic because people may change their behavior in response to a price increase.

Conclusion

Based on the analysis above, the good that would most likely be bought in the same quantity even if it doubled in price is A. Pencils. The demand for pencils is inelastic because people will not reduce their consumption of pencils even if the price increases. They are a necessity for daily activities, and people will still buy them in the same quantity even if the price doubles.

Recommendations

Businesses and policymakers should consider the elasticity of demand when making decisions about pricing and production. If a good has inelastic demand, it may be beneficial to increase the price to maximize profits. However, if a good has elastic demand, it may be beneficial to reduce the price to increase sales.

Key Takeaways

Elasticity of demand measures how responsive the quantity demanded of a good is to changes in its price.
Inelastic demand occurs when a large change in price leads to a small change in quantity demanded.
Unit elastic demand occurs when a change in price leads to a proportional change in quantity demanded.
The demand for pencils is inelastic because people will not reduce their consumption of pencils even if the price increases.
Businesses and policymakers should consider the elasticity of demand when making decisions about pricing and production.

Introduction

Elasticity of demand is a fundamental concept in economics that measures how responsive the quantity demanded of a good is to changes in its price. In this article, we will answer some frequently asked questions about elasticity of demand.

Q: What is elasticity of demand?

A: Elasticity of demand is a measure of how responsive the quantity demanded of a good is to changes in its price. It helps us understand how much the quantity demanded of a good will change when its price changes.

Q: What are the different types of elasticity of demand?

A: There are three types of elasticity of demand:

Elastic demand: When a small change in price leads to a large change in quantity demanded.
Inelastic demand: When a large change in price leads to a small change in quantity demanded.
Unit elastic demand: When a change in price leads to a proportional change in quantity demanded.

Q: How do I determine the elasticity of demand for a good?

A: To determine the elasticity of demand for a good, you need to analyze the relationship between the price of the good and the quantity demanded. You can use the following formula:

Elasticity of demand = (Percentage change in quantity demanded) / (Percentage change in price)

Q: What are some examples of elastic demand?

A: Some examples of elastic demand include:

Luxury goods: When the price of a luxury good increases, people may reduce their consumption of the good or look for cheaper alternatives.
Discretionary goods: When the price of a discretionary good increases, people may reduce their consumption of the good or look for cheaper alternatives.
Substitutes: When the price of a substitute good increases, people may switch to a different good.

Q: What are some examples of inelastic demand?

A: Some examples of inelastic demand include:

Necessities: When the price of a necessity increases, people may not reduce their consumption of the good.
Essential goods: When the price of an essential good increases, people may not reduce their consumption of the good.
Services: When the price of a service increases, people may not reduce their consumption of the service.

Q: How does elasticity of demand affect business decisions?

A: Elasticity of demand can affect business decisions in several ways:

Pricing: When a good has elastic demand, businesses may want to reduce the price to increase sales.
Production: When a good has inelastic demand, businesses may want to increase production to meet the demand.
Marketing: When a good has elastic demand, businesses may want to focus on marketing and advertising to increase sales.

Q: How does elasticity of demand affect policymakers?

A: Elasticity of demand can affect policymakers in several ways:

Taxation: When a good has inelastic demand, policymakers may want to increase the tax on the good to increase revenue.
Subsidies: When a good has elastic demand, policymakers may want to provide subsidies to increase consumption of the good.
Regulation: When a good has inelastic demand, policymakers may want to regulate the good to ensure that it is available to all consumers.

Conclusion

Elasticity of demand is a fundamental concept in economics that measures how responsive the quantity demanded of a good is to changes in its price. Understanding elasticity of demand can help businesses and policymakers make informed decisions about pricing, production, and marketing.
