For a linear demand function given by Qd_x = a0 + ax*Px + ay*Py + aM*M + aH*H, what is the formula for the own price elasticity of demand (EQx,Px)?
Explanation
This question tests the specific formula used to calculate own price elasticity from a linear demand function, as presented on page 91. It highlights that for linear demand, elasticity is not constant and depends on the point of measurement.
