Using data from the U.S, automobile industry we test for evidence consisten
t with game-theoretic models of advertising and quality signalling. We find
that manufacturers use both price and advertising to signal the quality of
their products; when price exceeds the full information case, manufacturer
s use above average levels of advertising. We also find a positive associat
ion between higher future sales and current advertising levels for automobi
le models. These results are consistent with game-theoretic signalling mode
ls and reported management practices. (C) 1998 Elsevier Science B.V. All ri
