“…Tobit regression was conducted to estimate the ‘beta’ coefficients, which explain expected WTP for health insurance and to show how WTP varies with respondents’ socio-economic characteristics. The marginal effects β ′ and β ″ were estimated where β ′ explained the marginal effects for the probability of being uncensored and β ″ explained the marginal effects for the expected WTP value conditional on being uncensored: E (WTP | WTP > 0) [ 41 , 42 ]. All analyses were carried out using STATA SE 14 (StataCorp LP, Texas, USA).…”

BackgroundThe Saudi Healthcare System is universal, financed entirely from government revenue principally derived from oil, and is ‘free at the point of delivery’ (non-contributory). However, this system is unlikely to be sustainable in the medium to long term. This study investigates the feasibility and acceptability of healthcare financing reform by examining households’ willingness to pay (WTP) for a contributory national health insurance scheme.MethodsUsing the contingent valuation method, a pre-tested interviewer-administered questionnaire was used to collect data from 1187 heads of household in Jeddah province over a 5-month period. Multi-stage sampling was employed to select the study sample. Using a double-bounded dichotomous choice with the follow-up elicitation method, respondents were asked to state their WTP for a hypothetical contributory national health insurance scheme. Tobit regression analysis was used to examine the factors associated with WTP and assess the construct validity of elicited WTP.ResultsOver two-thirds (69.6%) indicated that they were willing to participate in and pay for a contributory national health insurance scheme. The mean WTP was 50 Saudi Riyal (US$13.33) per household member per month. Tobit regression analysis showed that household size, satisfaction with the quality of public healthcare services, perceptions about financing healthcare, education and income were the main determinants of WTP.ConclusionsThis study demonstrates a theoretically valid WTP for a contributory national health insurance scheme by Saudi people. The research shows that willingness to participate in and pay for a contributory national health insurance scheme depends on participant characteristics. Identifying and understanding the main influencing factors associated with WTP are important to help facilitate establishing and implementing the national health insurance scheme. The results could assist policy-makers to develop and set insurance premiums, thus providing an additional source of healthcare financing.Electronic supplementary materialThe online version of this article (10.1007/s40258-017-0366-2) contains supplementary material, which is available to authorized users.

“…The Tobit model has the advantage of being able to efficiently estimate the relationship between an explanatory variable and some (censored) dependent variable to estimate the probability of a dependent variable being at or below (above) a limit [14,15]. …”

BackgroundContingent valuation (CV) is used to estimate the willingness to pay (WTP) of consumers for specific attributes to improve the quality of health care they received in three hospitals in Bangladesh.MethodsRandom sample of 252 patients were interviewed to measure their willingness to pay for seven specified improvements in the quality of delivered medical care. Partial tobit regression and corresponding marginal effects analysis were used to analyze the data and obtain WTP estimates.ResultsPatients are willing to pay more if their satisfaction with three attributes of care are increased. These are: a closer doctor-patient relationship, increased drug availability and increased chances of recovery. The doctor patient relationship is considered most important by patients and exhibited the highest willingness to pay.ConclusionsThis study provides important information to policy makers about the monetary valuation of patients for improvements in certain attributes of health care in Bangladesh.Electronic supplementary materialThe online version of this article (doi:10.1186/s12913-015-0678-6) contains supplementary material, which is available to authorized users.

“…Tobit regression is an efficient method for estimating the relationship between an explanatory variable and a truncated or censored continuous dependent variable because it estimates the probability of a dependent variable being at or less than a limit. 11 Log-transformed total IgE values showed the best approximation to normal distribution and were therefore used in the analyses. Cytokine levels were categorized into tertiles and used as ordinal variables in the analyses in mothers (prenatal and postpartum), in fathers, and in children at 12 months of age.…”
