Think Tank: The Geneva Association - Long-term care insurance research and trajectory

Source: Asia Insurance Review | Aug 2019

The financial risk of facing the costs associated with future needs for long-term care is still largely underinsured. In fact, the cost of such care can even be catastrophic, resulting in ruin for a number of elderly people and their families. The London School of EconomicsJoan Costa-Font, from the Geneva School of Business Administration’s Christophe Courbage and the Department of Actuarial Science of the University of Lausanne’s Joel Wagner explore this pressing issue.
 
 
The April issue of ‘The Geneva Papers on Risk and Insurance’ is devoted to the role of insurance in financing long-term care (LTC), and addresses three topics in particular: The reasons for a limited development of LTC insurance markets, the effect of LTC insurance purchase on the financial well-being of individuals, and the major research areas, both current and future, in the field of LTC insurance.
 
While LTC is mainly financed by governments through different types of public programmes, the limited level of public coverage, as well as increasing budgetary constraints have prompted a move towards developing insurance designs that address the specific institutional constraints of each country. 
 
Importance of supply and demand
However, so far, the market size for the different LTC insurance schemes has been relatively small in comparison to the very substantial amount of private expenditure and the significant level of self-insurance by families. The slow insurance development can be accounted for by a number of supply and demand factors. Such supply factors include questions associated with risk insurability, asymmetric information and pricing. As for demand factors, potential cognitive biases in risk perception, awareness of caregiving needs and the burden on family, and more especially the crowding out of public assistance and of family support are relevant.
 
The first set of papers investigate further those demand-side factors that could explain why the LTC insurance market is limited in size, focusing on LTC risk perception and family altruism.
 
The paper by Martin Boyer, Philippe De Donder, Claude Fluet, Marie-Louise Leroux and Pierre-Carl Michaud reports survey evidence on LTC risk misperceptions and demand for LTC insurance in Canada. 
 
To assess LTC risk misperceptions, they contrast subjective (stated) probabilities with objective (predicted) probabilities of needing help in the form of home care, access to a nursing home and living to the age of 85. They find that survey respondents’ misperceptions are quite small on average when assessing their LTC risk. Respondents are on average optimistic about their need for home care and about their survival probability but pessimistic about their nursing home need. 
 
Low take-up rates
They also find that, although misperceptions significantly affect both the intention to buy LTC insurance and the actual purchase of LTC insurance, they cannot explain the low take-up rate of LTC insurance in their sample. Correcting misperceptions would slightly increase LTC insurance take-up. Such results suggest that the awareness of risk misperceptions is only one explanation among many others for the small market for LTC insurance.
 
The paper by Justina Klimaviciute, Pierre Pestieau and Jérôme Schoenmaeckers analyses LTC insurance purchase decisions when parents expect to receive assistance from altruistic children. After proposing a simple theoretical model from which they construct various hypotheses on the parents’ insurance decision, they run an empirical test using data from the US, France, Spain, Germany and Israel. 
 
They find that the effect of children’s altruism is negative in Germany and Israel but not significant in the US, France and Spain, which possibly suggests that the different forces identified in the theoretical model - i.e., the degree of substitutability between informal and formal care, the degree of parental altruism and the intensity of risk aversion - offset each other. While family altruism is often cited among the factors explaining the thinness of the LTC insurance market, their paper indicates that in some countries, particularly in the US and in France, family altruism does not play such an important role.
 
A look at limitations
The second set of papers address the limitations of LTC insurance markets from a supply-side perspective and, more especially, investigate the role of moral hazard and solvency regulation in explaining the high level of LTC insurance premiums potentially deterring purchase.
 
In private LTC insurance markets, moral hazard is central to pricing and the long-run robustness of the market. Yet there is remarkably little evidence on the extent to which moral hazard exists in the presence of LTC insurance. The paper by Tamara Konetzka, Daifeng He, Jing Dong and John Nyman uses Health and Retirement Study data from 1996 to 2014 to assess moral hazard in nursing home and home care use in private LTC insurance. 
 
The research employs a combination of propensity score matching and instrumental variables approaches. They find evidence of significant moral hazard in home care use and a potentially meaningful but noisy effect on nursing home use. Their results suggest that policymakers, in designing incentives to promote private LTC insurance ownership, should consider the additional spending associated with moral hazard and potentially incorporate disincentives for socially inefficient spending by policyholders.
 
Mortality versus morbidity
The paper by Franca Glenzer and Bertrand Achou aims at quantifying mark-ups of premiums for LTC insurance due to mortality and morbidity risk. To this end, they model a shareholder value maximising insurance company that is subject to solvency regulation. Because liabilities from LTC insurance are more volatile than liabilities from annuities, capital provisions to ensure compliance with regulatory solvency requirements are higher if an insurance company offers LTC insurance instead of annuities. 
 
At the same time, a higher volatility in the LTC insurance segment also implies a higher expected payoff to the insurance company’s shareholders. Their results show that offering LTC insurance increases the upside potential to shareholders, but that effect is more than offset by a higher need for external capital. Consequently, if shareholders are to accept an LTC insurance segment, policyholders of an LTC insurance policy need to pay considerable mark-ups, which increases the importance of LTC insurance in the insurer’s overall book of business, explaining the high level of premium for LTC insurance.
 
Since financial protection is arguably the primary purpose of any insurance, LTC insurance can play an important role in financial planning for the elderly. However, there is little empirical evidence on the economic consequences of having LTC insurance, apart from its effects mainly on health services utilisation and informal caregiver outcomes. The paper by Jing Dong, Fabrice Smieliauskas and Tamara Konetzka tries to fill that gap by examining how LTC insurance affects key financial outcomes of insured individuals using US Health and Retirement Study data. They find that LTC insurance leads to consistently positive effects on assets, consistently negative effects on Medicaid and Food Stamp enrolment, as well as parent–child financial transfers and ambiguous effects on out-of-pocket medical payments. 
 
Upside of private LTC insurance
These results suggest that although private LTC insurance does not entirely protect insured individuals against large medical expenditures, it improves the general financial well-being of insured individuals, potentially by reducing Medicaid-related disincentives to asset accumulation, motivating individuals to save more and reduce intergenerational wealth transfers.
 
The final paper by Martin Eling and Omid Ghavibazoo provides a structured literature review of LTC insurance using main path analysis. They identify three major research areas (financing, demand, and insurability) and systematically evaluate them based on standard frameworks. Their results illustrate the significant difficulties of insuring LTC both on the demand and supply sides, explaining the low contribution of insurance mechanisms to LTC financing.
