    Notes

    Elasticity of Supply


    To measure the responsiveness of quantities supplied to a change in the price of a good, we use the elasticity of supply.


    In other words,

    Elasticity of Supply = %  change  in  quantity  supplied%  change  in  price  of  quantity\frac{\% \;change \;in \;quantity \;supplied}{\% \;change \;in \;price \;of \;quantity}


    To calculate the elasticity of supply, we use the following formula:

    Elasticity of Supply = (Q2Q1)/Qavg(P2P1)/Pavg\frac{(Q_{2}-Q_{1})/Q_{_{avg}}}{(P_{2}-P_{1})/P_{_{avg}}}

    Types of Supply Curves

    There are three types of supply curves which have different elasticity of supply.

    Case 1: Perfectly Inelastic

    The supply curve is vertical and has an elasticity of supply of 0.

    Perfectly inelastic supply curve

    In this case, a change in price leaves the quantity of supplied the same.

    Case 2: Unit Elastic

    The supply curve passes through the origin and is linear. The elasticity of supply is 1. Note that the slope of the curve does not matte. The elasticity of supply will always be 1.

    Case 3: Perfectly Elastic

    The supply curve is horizontal, and the elasticity of supply is \infty

    Factors Which Influences Elasticity of Supply

    Resource Substitution: If we can substitute resources to produce a good or service, then the elasticity of supply will be higher. With a small increase in price change, suppliers will produce more because they have more resource.

    Time Period for Supply: The longer time passes after a price change, the greater the elasticity of supply is.

    Momentary Supply: The longer time passes after a price change, the greater the elasticity of supply is.

    Short-run Supply: When there is a price change, and we want to look at small adjustments that changes the quantity supplied, then we look at the short-run supply. Short-run supply is somewhat elastic.

    Long-run Supply: When there is a price change, and we want to look at all possible adjustments that changes the quantity supplied, then we look at the long-run supply. Long-run supply is the most elastic.

    Introduction to Elasticity of Supply

    Welcome to our exploration of the elasticity of supply, a fundamental concept in economics. Our introduction video provides a crucial foundation for understanding this important topic. Elasticity of supply, defined as the responsiveness of quantity supplied to changes in price, is a key measure in economic analysis. It helps businesses and policymakers predict how supply will react to market fluctuations. The concept is essential for understanding market dynamics, pricing strategies, and resource allocation. Supply elasticity varies across industries and time periods, influencing production decisions and market outcomes. Factors such as production capacity, resource availability, and time frame all play a role in determining how elastic or inelastic supply is for a particular good or service. By grasping the nuances of supply elasticity, you'll gain valuable insights into how markets function and how producers respond to changing economic conditions.

    FAQs

    Here are some frequently asked questions about the elasticity of supply:

    1. What is the best definition of elasticity of supply in economics?

    Elasticity of supply is a measure of how responsive the quantity supplied of a good or service is to changes in its price. It's calculated as the percentage change in quantity supplied divided by the percentage change in price.

    2. How do you determine the elasticity of supply?

    To determine the elasticity of supply, use the formula: (Percentage change in quantity supplied) / (Percentage change in price). If the result is greater than 1, supply is elastic; if less than 1, it's inelastic; and if equal to 1, it's unit elastic.

    3. What is an example of a perfectly inelastic supply?

    A perfectly inelastic supply occurs when the quantity supplied doesn't change regardless of price changes. An example is a unique piece of art - no matter how high the price goes, only one original exists.

    4. Why is elasticity of supply important?

    Elasticity of supply is important because it helps businesses and policymakers understand how production might change in response to price fluctuations. This information is crucial for making decisions about pricing, production, and resource allocation.

    5. What are the factors that influence the elasticity of supply?

    Key factors influencing supply elasticity include: time frame (supply is generally more elastic in the long run), availability of resources, production capacity, storage capabilities, and the nature of the product (e.g., perishable goods tend to have less elastic supply).

    Prerequisites

    Understanding the concept of elasticity of supply is crucial for students of economics and business. While there are no specific prerequisite topics listed for this subject, it's important to recognize that a strong foundation in basic economic principles can greatly enhance your comprehension of elasticity of supply. This foundational knowledge allows you to grasp the nuances and applications of this important economic concept more effectively.

    Elasticity of supply is a measure of how responsive the quantity supplied of a good or service is to changes in its price. To fully appreciate this concept, students should have a solid understanding of supply and demand principles. Familiarity with these fundamental economic concepts provides the necessary context for exploring how suppliers react to price fluctuations in the market.

    Additionally, a basic grasp of microeconomics can be beneficial when studying elasticity of supply. Microeconomic principles help explain individual market behaviors and decision-making processes, which are directly relevant to how suppliers adjust their production levels in response to price changes. This background knowledge enables students to analyze and predict market outcomes more accurately.

    Mathematical skills, particularly in algebra and graphing, are also valuable when working with elasticity of supply. These skills allow students to calculate elasticity coefficients, interpret supply curves, and visualize the relationship between price and quantity supplied. Being comfortable with mathematical concepts enhances your ability to quantify and analyze supply elasticity in various scenarios.

    Furthermore, an understanding of production costs and business operations can provide valuable insights into why some goods or services may be more or less elastic in supply than others. This knowledge helps students comprehend the factors that influence a supplier's ability to adjust production in response to price changes, such as production capacity, resource availability, and time constraints.

    While not strictly prerequisites, familiarity with related economic concepts like price elasticity of demand, cross-price elasticity, and income elasticity can provide a more comprehensive understanding of market dynamics. These concepts often interact with supply elasticity, and understanding their relationships can lead to a more nuanced analysis of economic situations.

    In conclusion, although there are no specific prerequisite topics listed for elasticity of supply, a strong foundation in basic economic principles, microeconomics, mathematics, and business operations can significantly enhance your understanding of this important concept. By building this foundational knowledge, students can more easily grasp the intricacies of supply elasticity and its applications in real-world economic scenarios.
