Abstract
The Box-Cox transformation is used to compare alternative functional f orms of market value equations. Based on evidence from a panel of 480 publicly-traded U.S. manufacturing companies and two additional data s ets used previously in the literature, the semilog form of a Tobin's q equation is found to be strongly preferred to the commonly estimated linear form. We provide illustrations in which inferences can be affec ted by the choice of functional form.
