Complementing the commonly used concepts of evaluative wellbeing and decision utility, emotional wellbeing and experienced utility are important welfare criteria to assess individuals' subjective wellbeing, especially for valuing health and disability. Yet, almost all empirical evidences on the link between disability and experienced wellbeing come from developed countries. This paper studies the relationship between old-age disability and experienced utility in five low- and middle-income countries. Using data on individual time use and activity-specific affective experiences from an abbreviated version of the Day Reconstruction Method, we document a strong negative association between disability and experienced utility. These differences in experienced utility by disability status are exclusively due to worse activity-specific affective experiences among persons with disabilities. By contrast, disability-related differences in time use provide small compensating effects. Interventions or technologies that facilitate daily life hold most promise to improve experienced utility among persons with disabilities in the developing world.

This report is the first of its kind to measure health service coverage and financial protection to assess countries’ progress towards universal health coverage.

It shows that at least 400 million people do not have access to one or more essential health services and 6% of people in low- and middle-income countries are tipped into or pushed further into extreme poverty because of health spending.

This paper exploits the geographic expansion of performance-based financing (PBF) in Cambodia over a decade to estimate its effect on the utilization of maternal and child health services. PBF is estimated to raise the proportion of births occurring in incentivized public health facilities by 7.5 percentage points (25%). A substantial part of this effect arises from switching the location of institutional births from private to public facilities; there is no significant impact on deliveries supervised by a skilled birth attendant, nor is there any significant effect on neonatal mortality, antenatal care and vaccination rates. The impact on births in public facilities is much greater if PBF is accompanied by maternity vouchers that cover user fees, but there is no significant effect among the poorest women. Heterogeneous effects across schemes differing in design suggest that maintaining management authority within a health district while giving explicit service targets to facilities is more effective in raising utilization than contracting management to a non-governmental organization while denying it full autonomy and leaving financial penalties vague.

Objective
To evaluate the effect of vouchers for maternity care in public health-care facilities on the utilization of maternal health-care services in Cambodia.
Methods
The study involved data from the 2010 Cambodian Demographic and Health Survey, which covered births between 2005 and 2010. The effect of voucher schemes, first implemented in 2007, on the utilization of maternal health-care services was quantified using a difference-in-differences method that compared changes in utilization in districts with voucher schemes with changes in districts without them.
Findings
Overall, voucher schemes were associated with an increase of 10.1 percentage points (pp) in the probability of delivery in a public health-care facility; among women from the poorest 40% of households, the increase was 15.6 pp. Vouchers were responsible for about one fifth of the increase observed in institutional deliveries in districts with schemes. Universal voucher schemes had a larger effect on the probability of delivery in a public facility than schemes targeting the poorest women. Both types of schemes increased the probability of receiving postnatal care, but the increase was significant only for non-poor women. Universal, but not targeted, voucher schemes significantly increased the probability of receiving antenatal care.
Conclusion Voucher schemes increased deliveries in health centres and, to a lesser extent, improved antenatal and postnatal care. However, schemes that targeted poorer women did not appear to be efficient since these women were more likely than less poor women to be encouraged to give birth in a public health-care facility, even with universal voucher schemes.

Public providers have no financial incentive to respect their legal obligation to exempt the poor from user fees. Health Equity Funds (HEFs) aim to make exemptions effective by giving NGOs responsibility for assessing eligibility and compensating providers for lost revenue. We use the geographic spread of HEFs over time in Cambodia to identify their impact on out-of-pocket (OOP) payments. Among households withsome OOP payment, HEFs reduce the amount paid by 35%, on average. The effect is larger for households that are poorer and mainly use public health care. Reimbursement of providers through a government operated scheme also reduces household OOP payments but the effect is not as well targeted on the poor.Both compensation models raise household non-medical consumption but have no impact on health-related debt. HEFs reduce the probability of primarily seeking care in the private sector.

Medical expenditure risk can pose a major threat to living standards. We derive decomposable measures
of catastrophic medical expenditure risk from reference-dependent utility with loss aversion. We propose
a quantile regression based method of estimating risk exposure from cross-section data containing
information on the means of financing health payments. We estimate medical expenditure risk in seven
Asian countries and find it is highest in Laos and China, and is lowest in Malaysia. Exposure to risk is generally higher for households that have less recourse to self-insurance, lower incomes, wealth and education, and suffer from chronic illness.

In the absence of formal health insurance, we argue that the strategies households adopt to finance health care have important implications for the measurement and interpretation of how health payments impact on consumption and poverty. Given data on source of finance, we propose to (a) approximate the relative impact of health payments on current consumption with a ‘coping’-adjusted health expenditure ratio, (b) uncover poverty that is ‘hidden’ because total household expenditure is inflated by financial coping strategies and (c) identify poverty that is ‘transient’ because necessary consumption is temporarily sacrificed to pay for health care. Measures that ignore coping strategies not only overstate the risk to current consumption and exaggerate the scale of catastrophic payments but also overlook the long-run burden of health payments. Nationally representative data from India reveal that coping strategies finance as much as three-quarters of the cost of inpatient care. Payments for inpatient care exceed 10% of total household expenditure for around 30% of hospitalized households but less than 4% sacrifice more than 10% of current consumption to accommodate this spending.Ignoring health payments leads to underestimate poverty by 7–8% points among hospitalized households; 80% of this adjustment is hidden poverty due to coping.
