Ethnographic Heritage as a Branding Strategy: A Case Study of Yogurt in Bulgaria and Japan

Abstract

This article explores the various ways in which ethnographic images are deployed in branding strategies by Bulgarian and Japanese companies to frame industrial food as cultural heritage. Examining the history and marketing strategies of yogurt in Japan, I demonstrate how international marketing and cooperation has influenced the definitions, meanings and values of yogurt. In Japan, companies turn to ethnographic images of Bulgaria to sell their products, emphasizing visions of rural life over Bulgarian yogurt-making technology. At the same time, the fact that Bulgarian yogurt has turned into a symbol of health and wellbeing in one of the world’s economic powers is a source of national pride for consumers in post-socialist Bulgaria. The branding strategies of yogurt show how companies transform foods into culturally meaningful products, thereby doing much more than making profitable commodities of them. In educating and offering consumers new lifestyles, they change established systems of consumption and influence people’s imaginations.     

GMM estimation of a structural demand model for yogurt and the effects of the introduction of new brands

The demand structure for yogurt is assumed to be properly described by a one level nested logit model that is applied to aggregate market data. Given the presence of endogenous regressors, suitably lagged endogenous variables (Arellano and Bover in J Econom 68:29–51, 1995; Blundell and Bond in J Econom 87:115–143, 1998) are proposed as instrumental variables. The validity of this set of instruments is discussed and price elasticities and marginal costs are recovered from the demand estimates. Total welfare gains associated to the introduction of two new brands by the same manufacturer are finally computed. Prices and profits decreased and total welfare increased.
