Meta-Analysis dataset

Over the years, researchers from around the world have evaluated the Willingness to Pay ‎‎(WTP) for the reduction of beach litter using non-market valuation approaches. This research ‎study summarises the economic value of beach clean-ups and the underlying causes of WTP ‎variation observed in various primary studies. Using a meta-regression analysis, this study ‎estimates the global effect size of WTP and evaluates the causes of WTP heterogeneity across ‎regions. The uploaded data file contains a description of the variables used in the meta-‎analysis and the respective codes.‎
