  9. Welfare effects of Advertising • Dixit and Norman (1978) • A small increase in advertising raises welfare only if firms find it profitable. There cannot be too little advertising. • Reducing advertising from the profit maximizing level raises Welfare • Criticism of this result • May want to use pre-advertising preferences before ads and post advertising preferences after—Especially when the ads promote a change in quality (Fisher and McGowan 1979) • If the advertisements serve to inform consumers that the product exists, we may get too little advertising (Shapiro 1980) This slideshow was written by Ken Chapman, but is substantially based on concepts from Modern Industrial Organization by Carlton and Perloff, 4th edition, McGraw-Hill.
