    Study Notes

    Predicting Changes in Total Revenue

    • Price of a small cup of coffee is 2.50;managementconsidersraisingitto2.50; management considers raising it to 2.50;managementconsidersraisingitto3.
    • Price elasticity of demand (ED) is estimated at 1.5.
    • Price increase of 50 cents leads to a 20% increase in price (%ΔP).
    • Change in quantity demanded (%ΔQD) can be calculated using ED and %ΔP: |%ΔQD| = ED * |%ΔP|.
    • For this scenario, %ΔQD = 1.5 * 0.20, resulting in a 30% decrease in quantity demanded (QD).

    Changes in Total Revenue

    • Previous total revenue (TR) at 2.50with200cupssold/hour:TR=2.50 with 200 cups sold/hour: TR = 2.50with200cupssold/hour:TR=2.50 * 200 = $500/hour.
    • New expected QD after a 30% reduction is 140 cups/hour (200 - 60).
    • New total revenue after the price increase: TR = 3∗140=3 * 140 = 3∗140=420/hour.
    • Resulting in a decrease in total revenue from 500/hourto500/hour to 500/hourto420/hour when the price is raised.

    Graphical Representation of Total Revenue

    • Total revenue can be visualized as the area of a box on a graph, with width representing quantity and height representing price.
    • Previous revenue box (old TR) area calculates to 500(500 (500(2.50 * 200 cups/hour).
    • New revenue box (new TR) area calculates to 420(420 (420(3 * 140 cups/hour).

    Impact of Price Change on Total Revenue

    • If demand is elastic, increasing price decreases total revenue; if inelastic, increasing price increases total revenue.
    • A price increase will lead to increased TR if demand is inelastic and decreased TR if demand is elastic.
    • In this case, raising the price resulted in a fall in total revenue due to the elasticity of demand being greater than one.

    Price Elasticity of Supply

    • Price elasticity of supply (ES) measures producer responsiveness to price changes.
    • Categories include:
      • Inelastic supply (0 < ES < 1): Supply unresponsive to price changes.
      • Unit elastic (ES = 1).
      • Elastic supply (ES > 1): Supply responsive to price changes.

    Factors Affecting Elasticity

    • Flexibility of sellers affects how quickly supply can adjust to price changes.
    • Time horizon influences elasticity; short-run supply is often more inelastic compared to long-run supply.
