Basic necessities are generally said to be price inelastic in comparison with luxury goods. However, within the former group, it is not easy to differentiate between milk products using factors other price. Therefore, price could be an important factor when deciding between milk products. In this study, we verify the hypothesis that milk products are price elastic based on customer transaction data. If milk products are non-elastic in terms of price, we consider that people's choice of brand is decided by factors other than price, such as brand loyalty, which we then evaluate using a multinomial logit model.
