Question
Compute the elasticity for the exponential demand function $D(p)=a e^{-b p},$ where $a$ and $b$ are positive real numbers. For what prices is the demand elastic? Inelastic?
Step 1
The price elasticity of demand is given by the formula: \[E(p) = p \cdot \frac{D'(p)}{D(p)}\] where \(D'(p)\) is the derivative of the demand function with respect to price. Show more…

Elasticity of Demand Suppose that the demand equation for a certain commodity has the form $x=a e^{-b p},$ where $a$ and $b$ are positive constants. a. Find the elasticity of demand $E(p)$ b. Find the values of $p$ for which the demand is inelastic, unitary, or elastic.

Show that the demand function $D(p)=a / p^{b},$ where $a$ and $b$ are positive real numbers, has a constant elasticity for all positive prices.
