Practical implications – Consumers need to be aware that their consumption behavior can make a difference. They have to value the benefits of green products and understand why these are priced higher. Firms can apply pricing and promotional strategies addressing personal norms and inducing a higher WTP to capitalize on the opportunities of the green market segment. Originality/value – The study integrates WTP and personal norms as critical predictors into the TPB and furthermore expands the extant literature on green purchasing behavior to cover daily consumer goods extending beyond organic food. This enhances understanding of the structure of the constructs and determines their relative importance.
