The cyclical effect of advertising

Abstract

Purpose – The purpose of this paper is to provide an understanding of the effects of advertising based on economic cycles. To comprehend advertising effects in the restaurant industry from an economic cycle perspective, this study investigated both short- and long-run advertising effects under periods of economic contraction and expansion and compared those effects between the two economic periods. Design/methodology/approach – The data were collected from the COMPUSTAT database for the restaurant industry (SIC 5,812) from 1979 to 2010. To estimate the economic cycles, the 2005 year-based real gross domestic product (GDP) was used from the Bureau of Economic Analysis. Also, all variables were depreciated by the value of the US dollar in 2005. For estimation, a single equation error correction model was used to examine the short-term and long-term effects of advertising. Findings – The results of this study indicated that both the short- and long-term effects of advertising on sales growth were more obvious in contraction periods than in expansion periods. However, the short-run effects of advertising on brand equity did not significantly differ between expansion and contraction periods. Further, the long-term effects of advertising on brand equity were greater in expansion periods than in contraction periods. The findings suggest that restaurant firms should not reduce their advertising budgets during periods of economic contraction to take advantage of superior sales growth outcomes during these periods. Practical implications – The results of this study provide restaurant managers with useful practical implications. During economic contraction periods, restaurant managers should not reduce advertising budgets to take an ascendant position in terms of sales growth. Though the net positive effect at year t + 1 of contraction periods was smaller than that of expansion periods for sales growth, this is temporal and the long-run positive effect on sales growth spreads into future periods. Thus, a counter-cyclical advertising strategy could compensate for reduced sales from weak customer demands during economic contraction periods. Originality/value – There have been many empirical studies on the advertising effect in the literature. However, this study examined whether the effects of advertising differ between economic expansion and contraction periods. This specificity is helpful for industrial practitioners as well as academic researchers.
