There is a continuous increasing number of studies dealing with consumers' willingness to pay (WTP) price premiums for sustainable food products. This research focused on a broad area of sustainable food products, including different sustainable attributes using a meta-analysis of 80 worldwide studies. Overall average WTP was estimated using the forest plot, showing the existence of a high level of heterogeneity. The publication bias was also verified using the funnel plot and Egger's test. Finally, the subgroup analysis and meta-regression were applied to classify the source of heterogeneity. The results suggest that the overall WTP a premium for sustainability (in percentage terms) is 29.5% on average. Furthermore, gender, region, sustainable attributes and food categories influence the average WTP estimates and their heterogeneity. Results also indicate that the WTP estimate conducted by hypothetical approach is higher than non-hypothetical one due to hypothetical bias. Results also highlight that Asian WTP estimates, in percentage terms, are higher than those obtained in America and similar to those from Europe. In addition, positive WTP estimates are shown independent of the food categories, region or methods. This outcome denotes the presence of great market potential for sustainable products worldwide, which can provide a reference for relevant stakeholders to better understand market trends and the government to give more support to sustainable policies. ; Postprint (published version)

Public welfare in China is less universal, comprehensive, and generous when compared with other welfare regimes, especially for individuals with occupational disease. The assistance satisfaction of Chinese pneumoconiosis patients, a typical group of long-term social assistance recipients, has been linked to diminished health and psychological well-being. Self-acceptance is theorized to promote well-being, which may buffer the negative consequences of negative emotion on assistance satisfaction. This research was conducted based on the survey data of 1,345 patients in typical mining areas of China. In addition to single-factor analysis of variance, descriptive analysis, and correlation analysis, a cluster analysis was performed to explore the profiles of participants' ratings of assistance satisfaction with five governing subjects: government, employing unit, medical institution, welfare organization, and laborer themselves. The results were as follows: (1) Social assistance satisfaction perceived by Chinese long-term social assistance recipients was at an average level, wherein self-assistance satisfaction perception was the lowest among five dimensions. (2) The overall perception of assistance satisfaction of Chinese long-term social assistance recipients was significantly correlated with educational background and household monthly income; specifically, the participants with higher levels of education and lower levels of income were more likely to have higher assistance satisfaction perception. (3) Cross analysis showed that participants with higher assistance satisfaction were mainly from the low-high group, having a lower level of negative affect, and higher level of self-acceptance. (4) The average negative affect level was above the scale midpoint (3.65) and negatively associated with each of the assistance satisfaction ratings. (5) The analysis yielded three distinct profiles—medium (19.26%), high (40%), and low (40.74%)—according to their degree of assistance satisfaction. Relative to the other profiles, ...
