This study explores the effect of social capital on willingness to pay for social health insurance. Both quantitative and qualitative data were used to conceptualize; individual, community and organizational theories. Methods The data for this study is a sub sample from a dissertation study on the perspectives of social health insurance in post conflict C.E. state South Sudan. A sub-sample of 233 households, from C. E. State, were used. Analytical analyses of the social capital’s model were regressed. Findings. An average of about $ 43.5 dollars per annum, was achieved among the five (5) counties of C.E., State: - Juba, Kejikeji, Morobo, Terekeke and Yei River. Fifty-two 52% per cent of the expected subscribers for social health insurance were at the most likely scale of paying their medical costs. The social model is statistically significant at (p-value 0.0011) of the 95% per cent confidence. Indeed, social capital is effective among post conflict C.E. state. It enhances solidarity in social health insurance. Conclusions This research has added to the literature that positive expectations of social capital among post conflict C.E. State and willingness to pay for social health insurance is doable. Assisting impoverishers at the “most likely” scale is a significant norm of the social capital tenets. The individual within the community is bonded among his / her local organizations that is fruitful to social health insurance. Households had different barriers to act and through social solidarity, self-efficacy was very significant in explaining the variations in willingness to pay.

“…In order to check whether women differed from men in terms of specifying the most important factors while selecting ecological goods, the chi-square independence test was applied again in the course of conducted analyses. According to Kumakawa [ 35 ], an important topic for research on environmental evaluation is gender differences in willingness to pay for environmental goods. The table below shows the obtained research results ( Table 6 ).…”

This study discusses the identification of factors affecting consumers’ willingness to pay a price premium for ecological goods. The study was carried out in selected regions of Ukraine, in the cities of Kharkiv and Kyiv. The study applied various research methods, in particular public opinion analysis based on conducted surveys and the statistical inference method. The conducted research may constitute the scientific basis for the assessment of this market segment development. The comparison of consumer attitudes, presented by the residents of major Ukrainian cities regarding environmental goods, revealed their willingness to pay a price premium depending primarily on the purchasing power of the population, but also on gender, age, and social status. The analysis of differences in the cross-tabulation of quality characteristics was performed using Pearson’s chi-square test, which showed that, for example, men were more willing than women to choose environmental products due to their environmental safety and their selection was more often than in case of women based on environmental goods’ price. The collected research results can be used to assess the development prospects of environmental goods’ market, to construct the set of measures increasing the willingness level of domestic consumers to pay a price premium for ecological products, and to take up decisions about the production of ecological goods.

“…In studies regarding the economic valuation of environmental services, methods have been used based on revealed preferences (Albarracin et al , 2018; Van et al , 2017) and stated preferences (Guzman, 2015; Guevara, 2015; Dwyer, et al , 2015; Tamayo and Bedoya, 2017; Kumakawa, 2017; Romero and Cardenas, 2017; Younus and Sultan, 2018; Burrows et al , 2019).…”

Purpose The purpose of this paper is to present the first economic valuation of four environmental attributes of the Yanachaga–Chemillén National Park (PNYCH – Parque Nacional Yanachaga-Chemillén) in Peru. Design/methodology/approach This study included households in three cities adjacent to the PNYCH and assessed the willingness to pay (WTP) for preservation efforts of these natural services to avoid the predicted loss in forest area by 2030 (currently 143,425 hectares per year). Findings The results showed that the average WTP was US$0.695 (2.3197 soles) per household annually. Added to all households in Peru (9 million), this is equivalent to approximately 6.255 million dollars annually. Practical implications The economic valuation of these attributes is complementary to the contingent valuation and can have a significant impact, as this data influences decision-making and public policies focused on conserving forests and biodiversity. Social implications Upon using the choice experiment (CE) model, the attributes that have the most significant impact on inhabitants’ well-being were economic benefits. The flora and fauna coverage attributes were beneficial for the inhabitants of the place because they valued the proposed recovery and conservation program in a positive and differential way. Originality/value From the collection of valuable economic data, the novelty lies in using the CE method, which has not yet been applied in valuations of natural ecosystem services in Peru.
