Determinants for participating in the green insurance scheme: Binary logistic regression approach
The logistic regression model is used to identify the determinant/variables for the WTP for green insurance. The respondents were asked to reveal their preference/WTP for a hypothesised scheme of health insurance on a voluntary basis, given their budget constraints. The coefficients of the logistic regression for identifying the determinants for green insurance are presented in the Table 6.8.

The respondents are asked to reveal their WTP for a hypothesised scheme of green insurance on a voluntary basis, given their budget constraints. The coefficients of the logistic regression model for identifying the determinants for health insurance are the age of the respondent, marriage, number of family members, own house, respondents visiting government hospitals and WTP bids are showing the negative

probability related to WTP for green insurance. The current study reveals that the age of the respondents shows a significant negative relation with the probability of accepting the insurance scenario for green insurance, which implies that relatively older respondents are not willing to buy health insurance as compared to younger respondents. It might be because with the increase in age, cost of premium for insurance also increases. This is in line with the findings of the earlier studies of Bandara et al., 2013; Horton et ah, 2003, and Mandy, 1994. The negative value of the coefficient of the age of respondent shows the probability of willingness to participate in a green insurance scheme decreases with the increase in age of the respondents. Meanwhile, male respondents, levels of education (this is in line with findings of earlier studies such as Ali et ah, 2004 and Horton et ah, 2003), family income (Horton et ah, 2003; Blaine et ah, 2006), number of earning members in the family, environment pollution in your area, diseases in your area, frequency of occurrence of diseases, interest in conservation of green belt also show the positive relation with the probability of accepting the insurance scenario for green insurance.
Thus, out of the 15 variables, 10 variables are found to be significant in the study of the determinants for participating in the green insurance scheme in Binary Logistic Regression Approach. Levels of education, family income, number of family members, diseases in your area, interest in conservation of green belt and WTP bids are highly significant variables in the study of WTP for green insurance.
Derivation of demand curve for given BIDS for WTP for green insurance
There are five bid values - of Rs.200, Rs.500, Rs.1,000, Rs.1,500 and Rs.2,500. Respondents are asked whether they are willing to pay the bid offered to them randomly as a premium on timely basis for purchasing green insurance. The study shows that 59.11 per cent of the respondents in Delhi are willing to pay for green insurance. Out of these, 25 per cent of the respondents are willing to pay Rs.200,20 per cent are willing to pay Rs.500, 19 per cent are willing to pay Rs. 1,000 and Rs.1500, respectively and only 17 per cent are willing to pay Rs.2,500, as shown in Table 6.9.
Table 6.10 shows that WTP for green insurance is the highest at the lowest bid of Rs.200. 74.44 per cent of respondents are WTP for the proposed BID of Rs.200 given to them in the questionnaire. But the WTP gradually decreases with the increase in the bid value. WTP for green insurance is the lowest at

the highest bid of Rs.2,500. This is in line with the findings of earlier studies by Ali et al., 2004; Halvorsen et ah, 2004; Bala et ah, 1999; Whynes et ah, 2005. The findings give the shape of the demand curve for WTP for green insurance, which is a downward sloping curve as shown in Figure 6.2.
Thus, around 59.1 lper cent of the respondents are willing to pay the BID amount for green insurance, while the rest have rejected the proposed bid in the survey. The demand curve showing the WTP for green insurance is a downward sloping curve for the given BID amounts in rupees, as shown in Figure 6.2. The downward sloping curve shows that the WTP for green insurance decreases with the increase in the values of BIDS proposed to the respondents randomly.
