Relative importance of the fair-trade attribute and segmentation of the coffee market
A conjoint analysis was carried out for each respondent (using CONJOINT of SPSS).1 It computes the part-worth utilities of the levels of the attributes and the relative importance of each attribute (i.e., the ratio of the utility range of the considered attribute and the total sum of the utility ranges of all attributes). A summary for the whole sample was obtained by averaging the part-worth utilities and relative importance of the attributes over all the respondents. In 3Table 3, we show the average relative importance of the attributes and the part-worth utilities. The Pearson correlation and Kendall rank correlation coefficients between the estimated and observed preferences give an indication of the fit of the analysis.
