If the price falls from $16 to $10 and the quantity rises from 80 units to 100, however, the price decline is 37.5% and the quantity gain is 25%, an elasticity of (+ %) / (%) = for the same part of the curve. This is an example of the index number problem. [15] [16]
This is distinguished from a point swing, which is defined as the difference between the intraday high and the intraday low. Such records that turned negative are also recorded in a separate list.

We can use the value of the Lerner index to calculate the marginal cost (MC) of a firm as follows: 0.4 = (10 – MC) ÷ 10 ⇒ MC = 10 − 4 = 6. The missing values for industry B are found as follows: from the E d value of -2, we find that the Lerner index is 0.5. If the price is 30 and L is 0.5, then MC will be 15:
The rule of 25 vs. 4% rule. The rule of 25 is just a different way to look at another popular retirement rule, the 4% rule. It flips the equation (100/4% = 25) to emphasize a different part of the ...
