In summary, the researches on (country of origin) as single cues which have been reviewed above, are studies that focused on investigating the effects of country of origin on consumer's quality assessment, although some of the researches were conducted on different products and in different countries. The researches with (country of origin) as multi-dimensional type also led to similar findings. The difference between single-cue and multi-cues is that the researches which used (country of origin) as single-cue had greater effect size than those which used (country of origin) as multi-cues. The reason is that multi-cues type studies had additionally investigated on other variables which could influence consumer behaviors regarding product consumption (Peterson & Jolibert,1995 ; Verlegh & Steenkamp,1999). In other words, for a research on (country of origin) using the single cue design, the researcher has to focus on country of origin which influences consumer behavior in product consumption while controlling other factors. In contrast, for a research that uses the multi-cues design, the researcher has to study (country of origin) and other factors from informational cues, which could influence consumer behavior.
