The effects of fishery harbor-based brands on the brand equity of shore fish: An empirical study of branded mackerel in Japan

In Japan, some fishery cooperative associations use their fishery harbor names as a brand to differentiate their own shore fish. Most notable is the branding of mackerel. In this paper, we analyze the effects of branding using a discrete/continuous model. The results are as follows. First, there is first-mover advantage in the branding of mackerel. For instance, unlike other brands of mackerel, Seki-saba as the pioneering brand can increase its brand equity. Second, other brands have opposing effects that increase and decrease the brand equity of the pioneering brand. We find the former is strongest in the early stages of fishery branding when there are few competing brands of mackerel, while the latter becomes stronger in later stages when many other brands emerge.
