Switching welfare protection from the state to private insurance could result in millions of average and low earners having to pay more for their cover, according to research supported by the Joseph Rowntree Foundation.
Based on an analysis of costs in areas where private welfare insurance is already being marketed, the study concludes that public social security schemes may offer better value for money than is commonly supposed.
It also warns policy makers against assuming that private insurance offers a painless way out of the dilemma created by rising demand for welfare services and constraints on taxation and spending. The state could still face a rising bill for supporting 'high risk' individuals and many others unable to pay the private sector's premiums, while losing tax contributions from those who opt out.
Tania Burchardt and John Hills of the London School of Economics used data from 10,000 adults to examine private insurance in three different areas - to cover mortgage payments in case of unemployment or reduced earnings; to replace income during long-term sickness; and to meet the costs of care in old age.
They found that:
Effect on incomes
Looking at the effects of switching mortgage payment protection from tax-funded social security to private insurance, the analysis shows that people on higher incomes and non mortgage-holders would gain, while home-buyers with average to low incomes would lose out. A move away from flat-rate premiums in the insurance industry to rates based on an assessment of personal risk would mean even greater costs for lower income owners.
Commercial permanent health insurance policies would cost more than the equivalent state sickness benefit for people with low incomes, for women and for those classed as high risk, such as individuals with a history of poor health.
Illustrative calculations of the consequences of moving from state provision to private long-term care insurance suggested it would be equivalent to switching tens of thousands of pounds - over an individual's lifetime - from those at the bottom of the income distribution to those at the top. Women would lose out more than men because of their greater need for long-term care.
Tania Burchardt said: "If these case studies are typical of the kinds of risks that private insurance would be expected to cover, then policy makers should consider their options very carefully indeed before advocating any major shift from public to private welfare protection.
"Reliance on private insurance to cover long-term care looks an especially dubious proposition, since the state would still have to pay for uninsured individuals and for those who failed the stringent disability tests set by insurers. The considerable costs of premiums would, meanwhile, add to the pressures on government to hold down spending and taxation."
Policy options
The report urges policy makers to decide how a balance should be struck between public and private welfare insurance on a case by case basis. It identifies a spectrum of options ranging from no state involvement to protection financed entirely out of tax. These include:
John Hills said: "Given the tax and public spending constraints on government, it is tempting to see private replacements of welfare provision as a straightforward way to reduce revenue requirements. This study shows there could be major difficulties in implementing such a strategy.
"Private alternatives will, in some cases, cost the average family more while serving to make the rich richer and the poor poorer. But publicly-funded and provided provision is not the only alternative: there is a range of possible solutions - such as the hybrid National Care Insurance scheme suggested in a recent JRF report - that may be appropriate."
