We need to specify what we mean first.  In certain industries with great standardisation in a mass market, efficiency is, in effect, effectiveness.  The efficacy of McDonalds’ business model is its very efficiency, and this is what makes them so effective.  It isn’t effortless: they work effing hard at keeping costs low in delivering N burgers per M employees per hour.

But this isn’t the case for insurance.  While it varies by line of business, a typical model breaking down 100% of the total premium (i.e. decomposing the combined ratio) would look something like this:

    • 5% profit margin

    • 15% expenses

    • 20% acquisition costs

    • 60% claims costs

Our focus area for seeking efficiency improvements is just 15% of total revenues.  If we work really hard and get our expenses down by 5%, then we have improved combined ratio by 0.75%.
