Zhang T, Chen M. Inequality in benefit distribution of reducing the outpatient cost-sharing: evidence from the outpatient pooling scheme in China. Front Public Health 2024; 12:1357114. [PMID: 38500728 PMCID: PMC10945005 DOI: 10.3389/fpubh.2024.1357114] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2023] [Accepted: 02/22/2024] [Indexed: 03/20/2024] Open
Abstract
Objective The implementation of the outpatient pooling scheme in China has substantially elevated the compensation levels for outpatient expenses. This study aims to assess whether socioeconomically disadvantaged enrollees benefit proportionally compared to their non-disadvantaged counterparts. Method A cohort comprising 14,581 Urban and Rural Resident Basic Medical Insurance (URRBMI) enrollees and 830 Urban Employee Basic Medical Insurance (UEBMI) enrollees was derived from the China Health and Retirement Longitudinal Study 2018. Outpatient pooling scheme benefits were evaluated based on two metrics: the probability of obtaining benefits and the magnitude of benefits (reimbursement amounts and ratios). Two-part models were employed to adjust outpatient benefits for healthcare needs. Inequality in benefit distribution was assessed using the concentration curve and concentration index (CI). Results Following adjustments for healthcare needs, the CI for the probability of receiving outpatient benefits for URRBMI and UEBMI enrollees were - 0.0760 and - 0.0514, respectively, indicating an evident pro-poor pattern under the outpatient pooling scheme. However, the CIs of reimbursement amounts (0.0708) and ratio (0.0761) for URRBMI recipients were positive, signifying a discernible pro-rich inequality in the degree of benefits. Conversely, socioeconomically disadvantaged UEBMI enrollees received higher reimbursement amounts and ratios. Conclusion Despite a higher likelihood of socioeconomically disadvantaged groups receiving outpatient benefits, a pro-rich inequality persists in the degree of benefits under the outpatient pooling scheme in China. Comprehensive strategies, including expanding outpatient financial benefits, adopting distinct reimbursement standards, and enhancing the accessibility of outpatient care, need to be implemented to achieve equity in benefits distribution.

Abstract
This paper shows that selection incentives in downstream markets distort upstream prices. It is possible for inputs to be priced above the value that the good has for final consumers. We apply this idea to pharmaceutical companies selling drugs to a health insurance market with selection problems. We specify the conditions under which drugs are sold at prices exceeding treatment value. Another feature of the model is an excessive private incentive to reduce market size, e.g. in the form of personalized medicine.

Abstract
This study investigates the impact of long-term care insurance (LTCI) on the non-health consumption of elderly households. By exploiting a quasi-experiment on the public LTCI pilot program in China, we identify the effect of LTCI using a triple-difference approach. Using longitudinal data from the China Health and Retirement Longitudinal Study, we find that LTCI has led to an increase in the non-health consumption of elderly households by 15.7%, mostly observed in households having no older members with need for long-term care (LTC). Further evidence suggests that the effects are stronger for households with higher expected LTC risks, less wealth or family insurance, and covered by more generous schemes. Finally, LTCI increases the expectation of using formal LTC when disabled and subjective longevity expectations for older adults having no need for LTC. Overall, these findings offer empirical support for the role of LTCI in mitigating precautionary savings against LTC risks.

Abstract
BACKGROUND To improve equitable access to quality essential services and reduce financial hardship, low-and-middle-income countries are increasingly relying on prepayment strategies such as health insurance schemes. Among the informal sector population, confidence in the health system to provide effective treatment and trust in institutions can play an important role in health insurance enrollment. The objective of this study was to examine the extent to which confidence and trust affect enrollment into the recently introduced Zambia National Health insurance. METHODS We conducted a regionally representative cross-sectional household survey in Lusaka, Zambia collecting information on demographics, health expenditure, ratings of last health facility visit, health insurance status and confidence in the health system. We used multivariable logistic regression to assess the association between enrollment and confidence in the private and public health sector as well as trust in the government in general. RESULTS Of the 620 respondents interviewed, 70% were enrolled or planning to enroll in the health insurance. Only about one-fifth of respondents were very confident that they would receive effective care in the public health sector 'if they became sick tomorrow' while 48% were very confident in the private health sector. While confidence in the public system was only weakly associated with enrollment, confidence in the private health sector was strongly associated with enrollment (Adjusted odds ratio (AOR) 3.40 95% CI 1.73 - 6.68). No association was found between enrollment and trust in government or perceived government performance. CONCLUSIONS Our results suggest that confidence in the health system, particularly in the private health sector, is strongly associated with health insurance enrollment. Focusing on achieving high quality of care across all levels of the health system may be an effective strategy to increase enrollment in health insurance.

Abstract
Using data from the US Census Bureau's Household Pulse Survey, we analyzed the likelihood of loss of health insurance and enrollment into new health coverage during the early months of the COVID-19 pandemic. Loss of employment was associated with a significant increase in the likelihood of loss of health insurance and, specifically, an increase in the likelihood of employer-sponsored health insurance. However, individuals in Medicaid expansion states experienced a lower likelihood of loss of health insurance compared with individuals in nonexpansion states. At the same time, there was a statistically significant increase in Medicaid enrollment in expansion states, by 3.2 percentage points. Reemployment or acquiring employment was associated with a gain in health insurance coverage. During an economic downturn, eligibility, and coverage gaps leave many without affordable coverage options, and the pandemic will likely bring renewed attention to gaps in Medicaid coverage in nonexpansion states.

Abstract
Evaluating the impact of health insurance always remains a methodologically challenging endeavor due to the absence of sample randomization. This paper evaluates the impact of health insurance on the health status of children in Pakistan using the data of the Multiple Indicator Cluster Survey (MICS) for Punjab, Pakistan, from 2017 to 2018. The study adopted the propensity score matching (PSM) method to address the sample selection bias. The sample is matched on potential covariates such as mother characteristics (education level), household head characteristics (gender, age, and education), and other household conditions (such as home dwelling, internet access, wealth index, migration member, number of children residing in the home, as child illness, etc.). The findings revealed that children with insurance have considerably better health than non-insured, at a 1% significance level. The results confirm that health insurance is not a luxury but a need that improves children's overall health. In this regard, governments should enhance and expand programs related to health insurance, especially for children. Health insurance programs will not only help poor people but also improve the overall infrastructure of health services in the country.

Abstract
Insurance is typically viewed as a mechanism for transferring resources from good to bad states. Insurance, however, may also transfer resources from high-liquidity periods to low-liquidity periods. We test for this type of transfer from health insurance by studying the distribution of Social Security checks among Medicare recipients. When Social Security checks are distributed, prescription fills increase by 6-12 percent among recipients who pay small copayments. We find no such pattern among recipients who face no copayments. The results demonstrate that more-complete insurance allows recipients to consume healthcare when they need it rather than only when they have cash.

Abstract
We study the role of access to health insurance coverage as a determinant of individuals' subjective well-being (SWB) by analyzing large-scale healthcare reforms in the United States. Using data from the Behavioral Risk Factor Surveillance System and Panel Study of Income Dynamics, we find that the 2006 Massachusetts reform and 2014 Affordable Care Act Medicaid expansion improved the overall life satisfaction of Massachusetts residents and low-income adults in Medicaid expansion states, respectively. The results are robust to various sensitivity and falsification tests. Our findings imply that access to health insurance plays an important role in improving SWB. Without considering psychological benefits, the actual benefits of health insurance may be underemphasized.

Abstract
Building functional logistics systems and a healthy supplier base within low- and middle-income countries (LMICs) are key ways of providing steady, predictable supplies of health commodities for unpredictable demands for healthcare and health. Efforts to provide secure supplies of health commodities, whenever and wherever they are needed, however cannot ignore questions of whether there exists an external supportive environment in LMICs. Health planners must focus not just on capacities internal to logistics systems but also on external capacities. Internal and external capacities must be considered together and not in isolation. For this reason, a capacity-oriented commodity security framework, applicable to all therapeutic categories, is presented to help health planners in LMICs identify and evaluate the interrelated root causes of unreliable supplies in their respective countries.

Abstract
Moral hazard and adverse selection create inefficiencies in private health insurance markets and understanding the relative importance of each factor is critical for addressing these inefficiencies. We use claims data from a large firm which changed health insurance plan options to isolate moral hazard from plan selection, estimating a discrete choice model to predict household plan preferences and attrition. Variation in plan preferences identifies the differential causal impact of each health insurance plan on the entire distribution of medical expenditures. Our estimates imply that 53% of the additional medical spending observed in the most generous plan in our data relative to the least generous is due to adverse selection. We find that quantifying adverse selection by using prior medical expenditures overstates the true magnitude of selection due to mean reversion. We also statistically reject that individual health care consumption responds solely to the end-of-the-year marginal price.

Abstract
COVID-19 pandemic, the associated economic lockdown and the norms of social distancing have disrupted the business world. Most managers have struggled to make sense of the chaos and complexity around. Health insurance industry mangers are at the forefront of this challenge as new products and services covering COVID-19 had to be launched fast. This was both a market as well as the societal requirement. In the COVID-19 world, in different countries like United States of America (USA), United Kingdom (UK), Germany and India, attempts are being made to develop mobile applications for tracking COVID-19 patients. Emerging technologies have been altering the business landscape in most industries. The health insurance industry has also been witnessing the effects of technologies such as wearables technology, big data analytics, cloud technologies, blockchain, machine learning and such others. The advent of these technologies is fundamentally changing the health insurance industry. Given the realities of the COVID-19 world, the health insurance industry is poised at a crossroad of evolution where the industry would become data-intensive and data-driven. Health insurance firms have to enter into interfirm collaboration with wearable technology firms in the conversation on tracking social distancing from COVID-19 positive and potential cases. Health insurance firms might develop a service mechanism which could while maintaining the anonymity of COVID-19 positive or potential cases, ensure that customers who are using the wearable technology products and following social distancing norms are provided favourable premium for COVID-19 related health insurance products in case they were infected. This would be a novel addition to COVID-19 related products of health insurance firms. Deliberating on these aspects in this article, the authors propose a fundamental shift in the strategic orientation of health insurance firms.

Abstract
BACKGROUND Two of the objectives of Universal Health Coverage are equity in access to health services and protection from financial risks. This paper seeks to examine whether the type of health insurance enrollment affects the utilization of health services, choice of provider and financial protection of households in Togo. METHODS Data were obtained from a cross-sectional, representative household survey involving 1180 insured households that had reported either illness in the household in the 4 weeks preceding the survey or hospitalization in the 12 months preceding the survey. A nested logit model was used to account for the utilization of health services and provider choice, and methods of assessing catastrophic health care expenditures were used to analyze the level of household financial protection. RESULTS Policyholders of private health insurance use private health care facilities more than policyholders of public health insurance. The main reasons for not using health centers among households with public insurance were out-of-pocket payments (49.19%), waiting time (36.80%), and distance to the nearest health center (36.76%). Furthermore, on average, households with public insurance spent a higher proportion of their total monthly nonfood expenditures on health care than those with private insurance. We find that the type of insurance, share of expenditures allocated to food, distance to the nearest health center, and waiting time significantly impact the choice of provider. Regardless of the type of health insurance, elderly individuals avoid using private health centers and referral hospitals due to the high cost. CONCLUSION We found that a multiple health insurance system results in a multilevel health system that is not equitable for everyone. The capacity of the health insurance system to provide equitable health care services and protect its members from catastrophic health care expenditures should be at the core of health care reform. This study recommends raising awareness of the criteria for the reimbursement of medical procedures within the framework of public insurance and promoting specific health insurance mechanisms for elderly individuals. Careful attention should be paid to ensuring universal education and literacy as a means of improving access to and the use of health care.

Abstract
This paper investigates whether the voluntary deductible in the Dutch health insurance system reduces moral hazard or acts only as a cost reduction tool for low-risk individuals. We use a sample of 14,089 observations, comprising 2,939 individuals over seven waves from the Longitudinal Internet Studies for the Social sciences panel for the analysis. We employ bivariate models that jointly model the choice of a deductible and health care utilization and supplement the identification with an instrumental variable strategy. The results show that the voluntary deductible reduces moral hazard, especially in the decision to visit a doctor (extensive margin) compared with the number of visits (intensive margin). In addition, a robustness test shows that selection on moral hazard is not present in this context.

Abstract
We present a model in which health insurance allows liquidity-constrained patients access to otherwise unaffordable treatments. A monopolist's profit-maximizing price for an insured treatment is greater (for any cost sharing) than it would be if the treatment was not covered. Consumer surplus may also be less. These results are based on a different mechanism than would operate in a standard moral hazard model. Our model also provides an economic rationale for the common claim that pharmaceutical firms set prices that exceed the value their products create. We show this problem is exacerbated when health insurance covers additional monopoly-provided services.

Abstract
Cost-sharing is regarded as an important tool to reduce moral hazard in health insurance. Contrary to standard prediction, however, such requirements are found to decrease utilization both of efficient and of inefficient care. I employ a simple model that incorporates two possible explanations-consumer mistakes and limited access-to assess the welfare implications of different insurance designs. I find cost-sharing never to be an optimal solution as it produces two novel inefficiencies by limiting access. An alternative design, relying on bonuses, has no such side effects and achieves the same incentivization. I show how the optimal design can be deduced empirically and discuss possible impediments to its implementation.

Abstract
CONTEXT Health policy has long been preoccupied with the problem that health insurance stimulates spending ("moral hazard"). However, much health spending is costly healthcare that uninsured individuals could not otherwise access. Field studies comparing those with more or less insurance cannot disaggregate moral hazard versus access. Moreover, studies of patients consuming routine low-dollar healthcare are not informative for the high-dollar healthcare that drives most of aggregate healthcare spending in the United States. METHODS We test indemnities as an alternative theory-driven counterfactual. Such conditional cash transfers would maintain an opportunity cost for patients, unlike standard insurance, but also guarantee access to the care. Since indemnities do not exist in U.S. healthcare, we fielded two blinded vignette-based survey experiments with 3,000 respondents, randomized to eight clinical vignettes and three insurance types. Our replication uses a population that is weighted to national demographics on three dimensions. FINDINGS Most or all of the spending due to insurance would occur even under an indemnity. The waste attributable to moral hazard is undetectable. CONCLUSIONS For high-cost care, policymakers should be more concerned about the foregone efficient spending for those lacking full insurance, rather than the wasteful spending that occurs with full insurance.

Abstract
The exclusion of employment-based health insurance from income and payroll taxes
is thought to increase the generosity of insurance coverage and, in turn,
increase the overutilization of low-value health care services. We examine this
inefficiency of overinsurance by quantifying the change in expected utility
across 4 benchmark plans varying in actuarial value (AV) and focus on the
distribution of each of these estimates across different groups of people
varying in health status. Specifically, we quantify the changes in health care
spending due to moral hazard and the changes in uncertainty tied to risk
aversion using data from the nationally representative sample of adults with
employment-based coverage from the 2007-2016 Medical Expenditure Panel Survey,
and produce estimates of expected utility for 24 groups of people based on their
age, gender, and preexisting conditions. Our model suggests an average preferred
AV of 78% without the tax exclusion, with 29.0% of the population preferring a
60% AV, 6.5% preferring a 70% AV, 18.1% preferring an 80% AV, and 46.4%
preferring a 90% AV. When incorporating the distortionary effect of the
employment-based tax exclusion, the preferred plan increases to an 83% AV for
low-income people (with 71.0% of the population preferring a 90% AV) and an 84%
AV for high-income people (with 76.0% of the population preferring a 90% AV). We
estimate that policy changes to make subsidies independent of a plan’s AV could
result in increases in utility equal to about 2.7% of total health care
spending, but with those net gains concentrated among the healthy.

Abstract
We develop a set of frameworks for welfare analysis of Medicaid and apply them to the Oregon Health Insurance Experiment, a Medicaid expansion for low-income, uninsured adults that occurred via random assignment. Across different approaches, we estimate recipient willingness to pay for Medicaid between $0.5 and $1.2 per dollar of the resource cost of providing Medicaid; estimates of the expected transfer Medicaid provides to recipients are relatively stable across approaches, but estimates of its additional value from risk protection are more variable. We also estimate that the resource cost of providing Medicaid to an additional recipient is only 40% of Medicaid's total cost; 60% of Medicaid spending is a transfer to providers of uncompensated care for the low-income uninsured.

Abstract
There is strong interest in both developing and developed countries towards expanding health insurance coverage. How should the benefits, and costs, of expanded coverage be measured? While the value of reducing the financial risks that result from insurance coverage have long been recognized, there has been less attention in how best to measure such benefits. In this paper, we first provide a framework for assessing the financial value from health insurance. We focus on 3 distinct potential benefits: Pooling the risk of unexpected medical expenditures between healthy and sick households, redistributing resources from high to low income recipients, and smoothing consumption over time. We then use this theoretical framework and an illustrative example to provide practical guidelines for benefit-cost analysis in capturing the full benefits (and costs) of expanding health insurance coverage. We conclude by considering other potential financial effects of broad insurance coverage, such as the ability to consolidate purchases and thus lower input prices.

Abstract
Children in the United States suffered almost 118,000 cases of physical abuse in 2015. One factor that might help decrease child physical abuse is health care coverage. This paper presents a justification for a link between health care coverage and reductions in child physical abuse and, though it does not assess specific causal mechanisms, examines evidence for such a connection. The paper uses panel data linear regression analysis to explore state level physical abuse and health care coverage rates. Findings indicate a statistically significant relationship between increases in child health care coverage rates, including both private coverage and Medicaid coverage, and decreases in child physical abuse.

Int J Equity Health 2018; 17:137.

Abstract
Background China’s New Cooperative Medical Scheme (NCMS) enables insured citizens to enjoy the same benefit package by paying a flat-rate premium. However, it still remains uncertain whether economically disadvantaged enrollees receive insurance benefits that at least match those of non-disadvantaged enrollees. This article, therefore, estimates the distribution of benefits under the NCMS across economic groups and compares the magnitude of economic-related inequity changes in the NCMS benefits. Methods Data were drawn from two-wave large-scale representative and comparable cross-sectional household health survey datasets conducted in Shaanxi Province in 2008 and 2013. In total, 9506 (2008) and 38,010 (2013) NCMS enrollees were included. The benefits from the NCMS are measured in two ways: via the probability of receiving reimbursements and via the absolute amount of the obtained reimbursements. Two-part models were used to estimate the benefit distribution and to adjust benefits for health care needs. Concentration curve, dominance test of the concentration curve, and concentration index (CI) were used to estimate the overall degree of economic-related inequality. The degree of horizontal inequity was estimated via indirectly standardized measures based on the “equal treatment for equal needs” concept. Results Our results indicate that economically affluent groups were more likely to receive reimbursements from the NCMS, and these reimbursements were also higher. Positive need-adjusted CIs for the probability of receiving reimbursements (CIs: 0.2027/0.1056 in 2008/2013) and the absolute amount of reimbursements (CIs: 0.3002/0.1660 in 2008/2013) further suggest the existence of clear pro-rich horizontal inequities in the benefits distribution under the NCMS. Encouragingly, a decreasing trend could be observed from 2008 to 2013, which suggests that horizontal inequities in NCMS benefits that favored the rich decreased over the investigated period, while the level of insurance benefits improved. Conclusions Our study suggests that the benefits of NCMS are concentrated toward economically affluent groups. Although any trade-off between policy feasibility and equity has become a challenge for the formulation of social health insurance funding and benefit packages in developing countries, inequality can be gradually reduced through continuous adjustment of the medical insurance scheme, thus effectively targeting economically disadvantaged enrollees.

Abstract
I study the effect of the 1973 expansions of Medicare coverage among individuals with end-stage renal disease (ESRD) on insurance coverage, health care utilization, and mortality. I find that the expansions increased insurance coverage by between 22 and 30 percentage points, in models that include trends in age, with the increase explained by Medicare coverage, and increased physician visits by 25-35 percent. These expansions also decreased mortality due to kidney disease in the under 65 population by between 0.5 and 1.0 deaths per 100,000. Lastly, I provide evidence for two mechanisms that affected mortality: an increase in access to and use of treatment, which may be due to changes in insurance coverage; and an increase in entry of dialysis clinics and transplant programs.

Abstract
In a model where patients face budget constraints that make some treatments unaffordable without health insurance, we ask which treatments should be covered by universal basic insurance and which by private voluntary insurance. We argue that next to cost effectiveness, prevalence is important if the government wants to maximize the welfare gain that it gets from its health budget. Conditions are derived under which basic insurance should cover treatments that are mainly used by high risk agents with low income.

Abstract
Medicaid and the Child Health Insurance Programs (CHIP) are key sources of coverage for U.S. children. Established in 1997, CHIP allocated $40 billion of federal funds across the first 10 years but continued support required reauthorization. After 2 failed attempts in Congress, CHIP was finally reauthorized and significantly expanded in 2009. Although much is known about the demand-side policy effects, much less is understood about the policy's impact on providers. In this paper, we leverage a unique physician dataset to examine if and how pediatricians responded to the expansion of the public insurance program. We find that newly trained pediatricians are 8 percentage points more likely to subspecialize and as much as 17 percentage points more likely to enter private practice after the law passed. There is also suggestive evidence of greater private practice growth in more rural locations. The sharp supply-side changes that we observe indicate that expanding public insurance can have important spillover effects on provider training and practice choices.

Abstract
This study seeks to simulate the portion of moral hazard that is due to the income transfer contained in the coinsurance price reduction. Healthcare spending of uninsured individuals from the MEPS with a priority health condition is compared with the predicted counterfactual spending of those same individuals if they were insured with either (1) a conventional policy that paid off with a coinsurance rate or (2) a contingent claims policy that paid off by a lump sum payment upon becoming ill. The lump sum payment is set to be equal to the insurer's predicted spending under the coinsurance policy. The proportion of moral hazard that is efficient is calculated as the proportion of total moral hazard that is generated by this lump sum payment. We find that the efficient proportion of moral hazard varies from disease to disease, but is the highest for those with diabetes and cancer.

Abstract
Like other countries seeking a progressive path to universalism, Peru has attempted to reduce inequalities in access to health care by granting the poor entitlement to tax-financed basic care without charge. We identify the impact of this policy by comparing the target population's change in health care utilization with that of poor adults already covered through employment-based insurance. There are positive effects on receipt of ambulatory care and medication that are largest among the elderly and the poorest. The probability of getting formal health care when sick is increased by almost two fifths, but the likelihood of being unable to afford treatment is reduced by more than a quarter. Consistent with the shallow coverage offered, there is no impact on use of inpatient care. Neither is there any effect on average out-of-pocket health care expenditure, but medical spending is reduced by up to 25% in the top quarter of the distribution.

Abstract
This paper estimates the impact of social health insurance on financial risk by utilizing data from a natural experiment created by the phased roll-out of a social health insurance program for the poor in India. We estimate the distributional impact of insurance on of out-of-pocket costs and incorporate these results with a stylized expected utility model to compute associated welfare effects. We adjust the standard model, accounting for conditions of developing countries by incorporating consumption floors, informal borrowing, and asset selling which allow us to separate the value of financial risk reduction from consumption smoothing and asset protection. Results show that insurance reduces out-of-pocket costs, particularly in higher quantiles of the distribution. We find reductions in the frequency and amount of money borrowed for health reasons. Finally, we find that the value of financial risk reduction outweighs total per household costs of the insurance program by two to five times.

Abstract
In most health insurance markets in the United States, consumers have substantial choice about their health insurance plan. However additional choice is not an unmixed blessing as it creates challenges related to both consumer confusion and adverse selection. There is mounting evidence that many people have difficulty understanding the value of insurance coverage, like evaluating the relative benefits of lower premiums versus lower deductibles. Also, in most US health insurance markets, people cannot be charged different prices for insurance based on their individual level of health risk. This creates the potential for well-known problems of adverse selection because people will often base the level of health insurance coverage they choose partly on their health status. In this essay, we examine how the forces of consumer confusion and adverse selection interact with each other and with market institutions to affect how valuable it is to have multiple levels of health insurance coverage available in the market.

Abstract
BACKGROUND The Philippines failed to achieve its Millennium Development Goal (MDG) commitment to reduce maternal deaths by three quarters. This, together with the recently launched Sustainable Development Goals (SDGs), reinforces the need for the country to keep up in improving reach of maternal and child health (MCH) services. Inequitable use of health services is a risk factor for the differences in health outcomes across socio-economic groups. This study aims to explore the extent of inequities in the use of MCH services in the Philippines after pro-poor national health policy reforms. METHODS This paper uses data from the 2008 and 2013 Demographic and Health Survey (DHS) in the Philippines. Socio-economic inequality in MCH services use was measured using the concentration index. The concentration index was also decomposed in order to examine the contribution of different factors to the inequalities in the use of MCH services. RESULTS In absolute figures, women who delivered in facilities increased from 2008 to 2013. Little change was noted for women who received complete antenatal care and caesarean births. Facility deliveries remain pro-rich although a pro-poor shift was noted. Women who received complete antenatal care services also remain concentrated to the rich. Further, there is a highly pro-rich inequality in caesarean deliveries which did not change much from 2008 to 2013. Household income remains as the most important contributor to the resulting inequalities in health services use, followed by maternal education. For complete antenatal care use and deliveries in government facilities, regional differences also showed to have important contribution. CONCLUSION The findings suggest inequality in the use of MCH services had limited pro-poor improvements. Household income remains to be the major driver of inequities in MCH services use in the Philippines. This is despite the recent national government-led subsidy for the health insurance of the poor. The highly pro-rich caesarean deliveries may also warrant the need for future studies to determine the prevalence of medically unindicated caesarean births among high-income women.

Abstract
Background The National Health Insurance Scheme (NHIS) was launched in Ghana in 2003 with the main objective of increasing utilisation to healthcare by making healthcare more affordable. Previous studies on the NHIS have repeatedly highlighted that cost of premiums is one of the major barriers for enrollment. However, despite introducing premium exemptions for pregnant women, older people, children and indigents, many Ghanaians are still not active members of the NHIS. In this paper we investigate why there is limited success of the NHIS in improving access to healthcare in Ghana and whether social exclusion could be one of the limiting barriers. The study explores this by looking at the Social, Political, Economic and Cultural (SPEC) dimensions of social exclusion. Methods Using logistic regression, the study investigates the determinants of health service utilisation using SPEC variables including other variables. Data was collected from 4050 representative households in five districts in Ghana covering the 3 ecological zones (coastal, forest and savannah) in Ghana. Results Among 16,200 individuals who responded to the survey, 54 % were insured. Out of the 1349 who sought health care, 64 % were insured and 65 % of them had basic education and 60 % were women. The results from the logistic regressions show health insurance status, education and gender to be the three main determinants of health care utilisation. Overall, a large proportion of the insured who reported ill, sought care from formal health care providers compared to those who had never insured in the scheme. Conclusion The paper demonstrates that the NHIS presents a workable policy tool for increasing access to healthcare through an emphasis on social health protection. However, affordability is not the only barrier for access to health services. Geographical, social, cultural, informational, political, and other barriers also come into play.

Abstract
We propose a measure of household exposure to particularly onerous medical expenses. The measure can be decomposed into the probability that medical expenditure exceeds a threshold, the loss due to predictably low consumption of other goods if it does and the further loss arising from the volatility of medical expenses above the threshold. Depending on the choice of threshold, the measure is consistent with a model of reference-dependent utility with loss aversion. Unlike the risk premium, the measure is only sensitive to particularly high expenses, and can identify households that expect to incur such expenses and would benefit from subsidised, but not actuarially fair, insurance. An empirical illustration using data from seven Asian countries demonstrates the importance of taking account of informal insurance and reveals clear differences in catastrophic medical expenditure risk across and within countries. In general, risk is higher among poorer, rural and chronically ill populations.

Abstract
A fundamental implication of standard moral hazard models is overuse of low-value medical care because copays are lower than costs. In these models, the demand curve alone can be used to make welfare statements, a fact relied on by much empirical work. There is ample evidence, though, that people misuse care for a different reason: mistakes, or "behavioral hazard." Much high-value care is underused even when patient costs are low, and some useless care is bought even when patients face the full cost. In the presence of behavioral hazard, welfare calculations using only the demand curve can be off by orders of magnitude or even be the wrong sign. We derive optimal copay formulas that incorporate both moral and behavioral hazard, providing a theoretical foundation for value-based insurance design and a way to interpret behavioral "nudges." Once behavioral hazard is taken into account, health insurance can do more than just provide financial protection - it can also improve health care efficiency.

Abstract
In the health economics literature, the demand for health and market health inputs is dominated by adaptations of Grossman's health capital model. The model has been widely used to explore a wide range of issues related to health, socioeconomic inequalities in health, demand for medical care, health preventions, occupational choice, and retirement decisions. The commodity of health is viewed as a durable capital stock that yields a flow of healthy time or illness-free time, that depreciates with age, and that can be augmented with the help of market health inputs and own time. The purpose of this article is to provide a comprehensive critical review of the model. Underlying Grossman's model are a faulty conceptual framework and assumptions that tend to exaggerate the degree of control consumers/patients may have over their state of health and survival. The assumption of full information about one's state of health and the efficacy of various health inputs abstracts away from the problems posed by the agency relationship under uncertainty and informational asymmetry. Grossman's individualistic and mechanistic view of health strips health capital and its production of much of their biological/physiological content and their interactions with the individual's social and physical environment.

Abstract
Universal public finance (UPF)-government financing of an intervention irrespective of who is receiving it-for a health intervention entails consequences in multiple domains. First, UPF increases intervention uptake and hence the extent of consequent health gains. Second, UPF generates financial consequences including the crowding out of private expenditures. Finally, UPF provides insurance either by covering catastrophic expenditures, which would otherwise throw households into poverty or by preventing diseases that cause them. This paper develops a method-extended cost-effectiveness analysis (ECEA)-for evaluating the consequences of UPF in each of these domains. It then illustrates ECEA with an evaluation of UPF for tuberculosis treatment in India. Using plausible values for key parameters, our base case ECEA concludes that the health gains and insurance value of UPF would accrue primarily to the poor. Reductions in out-of-pocket expenditures are more uniformly distributed across income quintiles. A variant on our base case suggests that lowering costs of borrowing for the poor could potentially achieve some of the health gains of UPF, but at the cost of leaving the poor more deeply in debt.

Abstract
BACKGROUND Access to health insurance is expected to have positive effect in improving access to healthcare and offer financial risk protection to households. Ghana began the implementation of a National Health Insurance Scheme (NHIS) in 2004 as a way to ensure equitable access to basic healthcare for all residents. After a decade of its implementation, national coverage is just about 34% of the national population. Affordability of the NHIS contribution is often cited by households as a major barrier to enrolment in the NHIS without any rigorous analysis of this claim. In light of the global interest in achieving universal health insurance coverage, this study seeks to examine the extent to which affordability of the NHIS contribution is a barrier to full insurance for households and a burden on their resources. METHODS The study uses data from a cross-sectional household survey involving 2,430 households from three districts in Ghana conducted between January-April, 2011. Affordability of the NHIS contribution is analysed using the household budget-based approach based on the normative definition of affordability. The burden of the NHIS contributions to households is assessed by relating the expected annual NHIS contribution to household non-food expenditure and total consumption expenditure. Households which cannot afford full insurance were identified. RESULTS Results show that 66% of uninsured households and 70% of partially insured households could afford full insurance for their members. Enroling all household members in the NHIS would account for 5.9% of household non-food expenditure or 2.0% of total expenditure but higher for households in the first (11.4%) and second (7.0%) socio-economic quintiles. All the households (29%) identified as unable to afford full insurance were in the two lower socio-economic quintiles and had large household sizes. Non-financial factors relating to attributes of the insurer and health system problems also affect enrolment in the NHIS. CONCLUSION Affordability of full insurance would be a burden on households with low socio-economic status and large household size. Innovative measures are needed to encourage abled households to enrol. Policy should aim at abolishing the registration fee for children, pricing insurance according to socio-economic status of households and addressing the inimical non-financial factors to increase NHIS coverage.

Abstract
BACKGROUND The dramatic changes occurring in the age structure of the Thai population make providing healthcare services for the elderly a major challenge for decision makers. Because the number of the elderly will be increasing, together with the number of retired workers, under the Social Health Insurance (SHI) scheme, there will be the unmet needs for healthcare use after retirement. The SHI scheme does not cover workers after retirement unless they could use free healthcare for the elderly. In addition, the government budget is tight regarding the support of universal healthcare and long-term care services for all of the elderly. Therefore, the government could support retired workers who have the ability to pay by facilitating voluntary health insurance. OBJECTIVE The main objectives of the present study are to analyze the characteristics of workers that need health insurance after retirement and to identify the factors explaining healthcare use to offer healthcare services to meet the workers' needs and expectations. METHODS Four hundred insured workers under the Social Health Insurance (SHI) Scheme in Thailand were interviewed using a structured questionnaire. The Anderson-Newman model of healthcare use is the conceptual framework used in this study to understand the factors that explain healthcare use patterns of workers. Multiple regressions are employed extensively to evaluate the variables that predict healthcare use. RESULTS According to the survey, a person that purchases voluntary health insurance is likely to be female, have a higher personal income, and healthy. The characteristics related to healthcare use were poor health status, a high personal income, and peeople afflicted by chronic illness. CONCLUSIONS There is a gap between healthcare service use and the demand for voluntary health insurance. People that have a high income are more likely to purchase voluntary health insurance, while people in worse health and afflicted by chronic illness may have greater difficulty purchasing voluntary health insurance because they face higher premiums or are denied coverage by insurers.

Abstract
I investigate how changes in fees paid to Medicaid physicians affect take-up among children in low-income families. The existing literature suggests that the low level of Medicaid fee payments to physicians reduces their willingness to see Medicaid patients, thus creating an access-to-care problem for these patients. For the identical service, current Medicaid reimbursement rates are only about 65 percent of those covered by Medicare. Increasing the relative payments of Medicaid would increase its perceived value, as it would provide better access to health care for Medicaid beneficiaries. Using variation in the timing of the changes in Medicaid payment across states, I find that increasing Medicaid generosity is associated with both an increase in take-up and a reduction in uninsured rate. These results provide a partial answer to the puzzling question of why many low-income children who are eligible for Medicaid remain uninsured.

Abstract
In this essay we argue that the concept of affordable health insurance is rooted in a social obligation to protect fair equality of opportunity. Specifically, health insurance plays a limited but significant role in protecting opportunity in two ways: it helps keep people functioning normally and it protects their financial security. Together these benefits enable household members to exercise reasonable choices about their plans of life. To achieve truly affordable coverage, society must be able to contain the overall cost of health care, and health insurance must be progressively financed, meaning that those who are best able to pay for coverage should pay the largest share. While the recently passed Patient Protection and Affordable Care Act (ACA) falls short on both of these counts, we argue that it makes important contributions toward household affordability through the use of subsidies and regulations. The main shortcoming of the ACA is an insufficient protection against burdensome cost sharing, which we illustrate using several hypothetical scenarios. We conclude with recommendations about how to make opportunity-enhancing expansions to the current coverage subsidies.

Abstract
Background One of the key functions of health insurance is to provide financial protection against high costs of health care, yet evidence of such protection from developing countries has been inconsistent. The current study uses the case of Ghana to contribute to the evidence pool about insurance's financial protection effects. It evaluates the impact of the country's National Health Insurance Scheme on households' out-of-pocket spending and catastrophic health expenditure. Methods We use data from a household survey conducted in two rural districts, Nkoranza and Offinso, in 2007, two years after the initiation of the Ghana National Health Insurance Scheme. To address the skewness of health expenditure data, the absolute amount of out-of-pocket spending is estimated using a two-part model. We also conduct a probit estimate of the likelihood of catastrophic health expenditures, defined at different thresholds relative to household income and non-food consumption expenditure. The analysis controls for chronic and self-assessed health conditions, which typically drive adverse selection in insurance. Results At the time of the survey, insurance coverage was 35 percent. Although the benefit package of insurance is generous, insured people still incurred out-of-pocket payment for care from informal sources and for uncovered drugs and tests at health facilities. Nevertheless, they paid significantly less than the uninsured. Insurance has been shown to have a protective effect against the financial burden of health care, reducing significantly the likelihood of incurring catastrophic payment. The effect is particularly remarkable among the poorest quintile of the sample. Conclusions Findings from this study confirm the positive financial protection effect of health insurance in Ghana. The effect is stronger among the poor group than among general population. The results are encouraging for many low income countries who are considering a similar policy to expand social health insurance. Ghana's experience also shows that instituting insurance by itself is not adequate to remove fully the out-of-pocket payment for health. Further works are needed to address the supply side's incentives and quality of care, so that the insured can enjoy the full benefits of insurance.
