초록
Domestic abalone consumption grows in proportion to increasing outputs of cultured abalones. This paper uses consumer survey data obtained in 2007 and 2008 to analyze factors affecting the frequency of at-home and restaurant abalone consumption with the notice of increasing abalone consumption. Data about marine product consumption intrinsically have problems regarding a large proportion of zero observations and interdependence of at-home and restaurant consumption. Therefore, this study uses bivariate SUR tobit model to solve such problems. Analysis results show that there is statistically significant interdependence between two kinds of consumption frequency. In other words, given weak substitution relation between at-home and restaurant abalone consumption, it was likely that respondents perceived the difference between the former and the latter. From estimated coefficients, it was possible to calculate income elasticities of consumption by regional groups and compare them. This paper can provide information on division of the abalone consumption market into groups with high willingness to consume and implementation of marketing strategies for meeting demands of at-home and restaurant abalone consumption. The methodology of this study can be applied to other marine products.
Abstract
Domestic abalone consumption grows in proportion to increasing outputs of cultured abalones. This paper uses consumer survey data obtained in 2007 and 2008 to analyze factors affecting the frequency of at-home and restaurant abalone consumption with the notice of increasing abalone consumption. Data about marine product consumption intrinsically have problems regarding a large proportion of zero observations and interdependence of at-home and restaurant consumption. Therefore, this study uses bivariate SUR tobit model to solve such problems. Analysis results show that there is statistically significant interdependence between two kinds of consumption frequency. In other words, given weak substitution relation between at-home and restaurant abalone consumption, it was likely that respondents perceived the difference between the former and the latter. From estimated coefficients, it was possible to calculate income elasticities of consumption by regional groups and compare them. This paper can provide information on division of the abalone consumption market into groups with high willingness to consume and implementation of marketing strategies for meeting demands of at-home and restaurant abalone consumption. The methodology of this study can be applied to other marine products.
