New York: Wiley and Sons. Effective public service advertisements to attract volunteers for the Special Olympics: an elaboration likelihood perspective. Journal of Advertising, 35(1), 7–21. We integrated several endorser variables and the properties of the endorsed object. 1997). In addition, longitudinal analyses show a steady increase over the past years (Erdogan 1999; Pringle and Binet 2005). Food choice and overconsumption: effect of a premium sports celebrity endorser. Journal of Consumer Research, 19(1), 34–51. Journal of Political Marketing, 6(4), 67–83. About half the total variability could be attributed to the between-study heterogeneity (I2 = 51.53%, third level) and about 11% could be attributed to the between-type of effect size within study heterogeneity (I2 = 11.45%, second level). D) Herzberg's two-factor theory. How does the dialectical thought of adulthood differ from the dichotomous thought of adolescence? Accordingly, several studies have supported the product match-up hypothesis (Erdogan 1999). Sanbonmatsu, D. M., & Kardes, F. R. (1988). The databases were examined using the term celebrit* in combination with endors*, spokes*, or advert* in any available search field. However, research investigating celebrity meaning transfer is relatively scarce. Compared to all previous research (see Erdogan 1999), we are now able to provide practitioners with a clear effect direction. Average effect sizes were estimated taking the random-effects perspective, and moderator analyses were performed applying the mixed-effects models (meta-regression). Instead of continuing to prove the effect, future research should rather look for its underlying psychological mechanism as well as boundary conditions. Celebrity and noncelebrity advertising in a two-sided context. reproductive system, motor ability, strength, and lung capacity are at their best. As a result, studies reporting only one effect size received the same weight as studies reporting multiple effect sizes if their sample size was equal. Journal of Marketing, 63(1), 26–43. Furthermore, the model—being a broad overarching framework—enabled the integration of various sub-theories to explain specific effects. Otherwise, the meta-analyzed effect size would equal the sole obtained effect size, rendering meta-analysis useless. work at d>0 employers, and this implies that wb
