Gender discrimination and insurance

The EU's ban on gender discrimination in insurance from the end of 2012 will have costs as well as benefits. Neither banning nor allowing gender discrimination seems to me egregious public policy. I therefore regarded this area as a low priority for reform.

Be that as it may, the concept of loss coverage is relevant to understanding and measuring the effects of the ruling. Insurers and actuaries frequently claim that restrictions on discrimination will lead to adverse selection: that is, more insurance will be bought by the higher-risk gender, and less by the lower-risk gender, and the total number of policies sold may fall.

But this so-called 'adverse' selection is not necessarily adverse. A fall in numbers insured can be consistent with a higher number of losses compensated by insurance, if more of the 'right' people - that is, the higher risks - buy insurance.

In other words, a fall in numbers insured can be consistent with higher loss coverage.

Some novel perspectives on risk classification
(Geneva Papers on Risk & Insurance, 2007)
Pages 22 to 23 of this article explain the conflict between insurance ideology and legal concepts of gender equality. Succinctly, the law reflects a common social opinion by treating statistical discrimination per se as offensive. The problem is not (as insurers often allege) that critics do not understand the principle; the problem is that they do understand, and recognise the insurers' ideology as one which they explicitly reject. pdf (28 pages)
