Exploration of how much consumers are willing to pay for different milk attributes across geographic regions

This data is for the 123 research articles on consumers' willingness to pay for dairy and plant-based milk attributes compiled for the scoping review titled "Consumers' willingness-to-pay for dairy and plant-based milk attributes : a scoping review". The scoping review aimed to accomplish the following five goals: (1) identify and evaluate the milk and plant-based milk alternatives products and attributes that have been explored in WTP studies, (2) explore how much consumers are willing to pay for different milk attributes across geographic regions, (3) identify key factors driving consumers' WTP for milk and plant-based milk alternatives (4) explore different methods used, (5) identify potential research areas in understanding WTP studies on dairy and plant-based milk alternatives. The Cochrane Handbook for systematic reviews of interventions was used for search, selection, and data extraction methods (Higgins et al., 2019). <br> The protocol development and the report followed the preferred reporting items for systematic literature reviews and meta-analyses (PRISMA) guidelines and checklists (Moher et al., 2009). Search terms for consumers, WTP and milk were obtained from previous systematic literature review studies on consumers (Alsubhi et al., 2023; De Steur et al., 2017), WTP (Alsubhi et al., 2023; De Steur et al., 2017; Olum et al., 2020) and milk (Largueza et al., 2023; Zeltzer et al., 2022). The search terms for milk were adopted as milk and soymilk since other articles on soymilk were not included in the search term milk. Other plant-based milk alternatives have a separate term, milk; therefore, they were included by the search term milk as confirmed by iterations with the search terms.
