Spending on Luxury Food

A subset of the original study on consumers’ willingness to pay for “luxury food” by Hartmann et al. (2016, 2017). The part<br> of the dataset we examine consists of 821 observations of 44 Likert-type items on eating and shopping habits, diet styles, price, and luxury statements in general. One such item is, for example, “I associate a high price in food with particularly good quality”, with coding scheme −2 = ‘strongly disagree’, . . . , +2 = ‘fully agree’. The coding scheme of the remaining items is similar and given in the file luxfood_description.pdf. The last column contains the response of interest in our analysis, which pertains to whether participants would be willing to pay a higher price for a food product that they associate with luxury (v_60), measured again on the ordinal −2 to +2 scale. <strong>References</strong> Hartmann, L.
