KEOGH PLAN: A savings retirement plan for self-employed workers authorized by the Self-Employment Individuals Retirement Act (1982). A Keogh plan is similar to an IRA (individual retirement account), but is a bit more complicated to establish. Like other private pension plans, income diverted to Keogh plans are tax deferred, that is, taxes on not paid on the income until it is withdrawn during retirement.

Lesson 11: Elasticity Basics | Unit 3: Measurement Page: 13 of 25

Topic: Doing The Numbers: Endpoint <=PAGE BACK | PAGE NEXT=>

  • Our task is to calculated the price elasticity of demand using the endpoint formula. I am presenting the endpoint formula for reference.

    endpoint
    elasticity
    =(Q2 - Q1)
    Q1
    ÷(P2 - P1)
    P1

  • Suppose the values for this formula are P1 = $2.49, Q1 = 5,447 unit of a given good (say Tacos), P2 = $1.99, Q2 = 6,608 units of Tacos

    endpoint
    elasticity
    =0.21 ÷ - 0.20=- 1.05

  • This value - 1.05 indicates that the a one percent decline in the price of Tacos results in a 1.05 percent increase in quantity demanded.

SECOND-DEGREE PRICE DISCRIMINATION

A form of price discrimination in which a seller charges different prices for different quantities of a good. This also goes by the name block pricing. Second-degree price discrimination is possible because decidedly different quantities are purchased by different types of buyers with different demand elasticities. This is one of three price discrimination degrees. The others are first-degree price discrimination and third-degree price discrimination.
