An opinion on this interesting question: areas such as fire safety (see for example the US NFPA) and maritime safety are largely driven by insurance companies rather than safety regulators, and outcomes don't seem to be appallingly poor. In areas where threats
to life are more important/visible to the public, there is a clear tendency to combine the use of multiple risk regulation instruments (prescriptive regulation, performance-based regulation, information regulation, liability law, insurance, "soft law"). Presumably
the defence-in-depth benefits are assumed to outweigh the extra costs from multiple sources of risk regulation. </div>

<b>Objet :</b> [SystemSafety] How far does insurance economic incentive push safety?</font>
<div> </div>
</div>
<div class="BodyFragment"><font size="2"><span style="font-size:11pt;">
<div class="PlainText">I'm looking for opinions and previous work regarding the proposition
<br>
that insurance premium economic pressure -- all by itself -- is likely <br>
to result in an ALARP or similar safety outcome for life critical <br>
systems (trains, planes, automobiles, etc.) in the absence of regulation <br>
or any other safety pressure. Details below if this is of interest.<br>
<br>
--------------<br>
<br>
I am interested in the relationship between economic pressure from <br>
insurance premiums and safety outcomes. I realize these things are <br>
messy, there are multiple factors in practice, "it all depends," and <br>
that regulation to some degree puts its thumb on the scale (some domains <br>
more than others), so I understand this is something of a theoretical <br>
exercise.<br>
<br>
I'd expect some correlation. In particular I'd think that as a <br>
generality improving safety will over the long term yield lower <br>
insurance premiums (assuming an efficient competitive market, not <br>
worrying about negotiating power imbalance between individual consumers <br>
and insurance providers, etc.). I'm aware there are complications such <br>
as expensive crash protection consumables that are damaged in the course <br>
of reducing harm severity that can push back against this correlation. <br>
And I'm aware of liability issues, but let's say insurance ultimately <br>
pays out for those too. And "self-insurance" counts as insurance.<br>
<br>
The pointed question of interest is whether there is a reason to believe <br>
that insurance premium economic pressure, all by itself, is likely to <br>
lead to acceptable safety for life critical systems.<br>
<br>
My initial position is that I'd be surprised if insurance premiums alone <br>
(with no regulation) necessarily result in an ALARP result for typical <br>
modes of transportation. I'd expect they'd prevent a really horrible <br>
result, but not necessarily safety I'd want to have in transportation <br>
I'm personally going to use.<br>
<br>
Among other reasons, if insurance premiums resulted in ALARP, I'd expect <br>
we wouldn't need regulators (which we do need in practice).<br>
<br>
But perhaps I'm wrong. Or perhaps insurance economics driving ALARP <br>
is <br>
true in theory but not in practice for reasons that are interesting.<br>
<br>
Does anyone know of a good treatment of this topic?<br>
<br>
Thanks,<br>
