COMPARABLE WORTH: The notion that different jobs requiring comparable, but not identical, skills should be paid the same wage. The logic behind comparable worth is that centuries (perhaps even millennia) of discrimination against women by men have relegated women to secondclass, poorly paid jobs with little or no chance for advancement. Men, in contrast, with the same education, skills, and abilities are able to get the better, higher paying jobs. Comparable worth would be a program in which different jobs are evaluated and scored, based on the skills, responsibilities, and education needed. Jobs with the same scores would then be required to have the same pay.

ENDPOINT ELASTICITY FORMULA: A simple technique for calculating the coefficient of elasticity by estimating the elasticity for discrete changes in two variables using the initial values of each. The distinguishing characteristic of this formula is that percentage changes are calculated based on the initial values of each variable. An alternative technique is the midpoint elasticity formula. The endpoint elasticity formula is a simple, firstapproximation, method of calculating elasticity, especially the price elasticity of demand, price elasticity of supply, income elasticity of demand, and cross elasticity and demand. This formula is most often used at the introductory level of economic instruction.The FormulaThe endpoint elasticity formula for calculating the response of changes in B to changes in A is given as:endpoint elasticity  =  (B2  B1) B1  ÷  (A2  A1) A1 
The first term on the righthand side of the equation is the percentage change in variable B. The second term is the percentage change in variable A. The individual items are interpreted as this: A1 is the initial value of A before any changes, A2 is the ending value after A changes, B1 is the initial value of B before any changes, and B2 is the ending value after B changes.The numerator of each term on the righthand side of the equation [(A2  A1) and (B2  B1)] is the discrete change in A and B, respectively. The denominator of each term, A1 and B1, is the base value from which the percentage change is calculated. An Simple ExampleA Standard Demand Curve 

 The time has come for a numerical example to illustrate. The demand curve to the right should help. Suppose the demand price of Wacky Willy Stuffed Amigos (those cute and cuddly armadillos and tarantulas) INCREASES from $10 to $12. This price increase causes the quantity demanded to decrease from 5 to 4 Stuffed Amigos. Using the endpoint elasticity formula, the price increases by 20 percent, a $2 increase from a $10 initial price. This method also results in a 20 percent decrease in the quantity demanded, a decline of 1 Stuffed Amigo from an initial value of 5. This seems relatively simple and straightforward. The price elasticity of demand using the endpoints elasticity formula is thus equal to 1.Or is it? An Endpoint ProblemThe problem with the endpoints elasticity formula for demand elasticity is that the coefficient of elasticity depends on whether price increases or decreases. This is demonstrated by asking the question: What is the coefficient of elasticity for this same range of the demand curve, if the price DECREASES from $12 to $10 causing the quantity demanded to increase from 4 to 5? In this case, the change in price is 16.7 percent, a $2 decrease from a $12 initial price, and the change in quantity is 25, an increase of 1 Stuffed Amigo from an initial value of 4. This results in a coefficient of elasticity of 1.5.Over the same segment of the demand curve, a price INCREASE indicates a different coefficient of elasticity than does a price DECREASE. This can become confusing. This problem is prevented by using an alternative method of calculating the coefficient of elasticity, the midpoint elasticity formula. This alternative uses the average of the beginning and ending values of each variable (that is, the midpoint) as the base value for calculating percentage changes. If the discrete changes are relatively small, then the two methods are approximately the same.
