Way back in Episode 006 while exploring the concept of risk I said that much of the banking industry was founded upon the need to and with the goal of managing risk. Let’s now look deeper into one of the most widespread and relatable of such instruments. But first we go to FictionTown. Steve, Bryan, Brenda and Irene are sat in the frontyard of one of their houses and having a sombre chat. News is that one of the houses in their community burned down. Obviously our friends are terrified at the possibility of this happening to their house. Steve starts, astutely as usual: this should not happen! Bryan’s like, Steve, you can’t control certain things. Brenda chips in, well, if we can’t control it, we should manage the damage, like save up to rebuild or something. Irene interjects, hmm, it’d be too hard for each of us to save up that much, wait, what if we all saved up in one collective pot, how many houses are there in our community? Steve says it’s about 50 but cannot see how that matters. But Bryan’s like, wait, Irene, that way you mean it can be used if any one house burns down? But how much do we each put? Brenda makes a different point, wait, it’s not just present quantity, how often does a burndown fire happen - the last one was 5 years ago. Irene gets it all - right, we should check the pattern at the Mayor’s office records, but, assuming on average there’s one such fire in 5 years, and we are 50 houses, we each pay a two-hundred-and-fiftieth (1/250) of the pot each year, which becomes even easier to foot if paid in monthly than in a lumpsum! Pot Luck That’s it, that’s insurance in a nutshell, or in a nice collective pot! Obviously, the mathematics of it in the real world is a lot more complicated, and the whole thing is managed by distinct commercial outlets - the insurance companies, who inevitably charge a cut for their services, but this encapsulates the concept with the basic elements in place. Let’s see what’s actually happening here. As we discussed in the risk episode, everything in life is contingent - we can never tell what’s going to happen next. But based on past performance (which by the way is no guarantee of the future), the best we can do is calculate future probability. So if in FictionTown, the last burndown was 5 years ago, the one before 11 years ago and the one before 15 years ago, we can cautiously take 5 years as the average frequency. Generally, the larger the scope of our past dataset, the easier it is to identify patterns. And we saw how there is the ‘pooling’ of risk among all 50 houses, which as we noticed, and as we might intuitively know, softens the blow on any individual. We must also be aware that such a scenario as depicted implies an insurance based solution manifests ‘after the fact’ - it cannot prevent the fire in the first place, but as we’ll see, even there, there’s nuance. Can you Count on it? The key goal of statistics and probability, the cornerstone sciences of risk management is to put a number on the innumerable, express the unquantifiable in exact money terms. Ultimately, how do you measure risk, really? Why is my insurance premium $100 and not $50? While I’ll get to these more complex topics when the time’s right, what we take away at the moment is the simple idea of turning scary unpredictable losses into a small predictable cost. Again, this is not perfect, and based on changing circumstances, the insurance premiums we have to pay might keep changing constantly, and with advances in data collection and similar technologies, this could become even more fluid. But we all know we are required, often by law, to foot insurance bills: car insurance, health insurance, travel insurance, whatever it may be. It may be frustrating to see money you could’ve used elsewhere go into some external source which, unless a stated calamity materializes, you never get back. (consider this weird paradox: almost anything you buy, you actually want to use it. But with insurance, you actively prefer not to?) But what you’re paying for here is the peace of mind that should the worst (the insurance company defines ‘worst’ btw!) happen, at least you are ‘covered’ (again, mainly in terms of financial payout, you cannot undo the accident or another incident.) (Also, just to note, a state-run free-at-the-point-of-use health service doesn’t mean you’re not paying for it, just that it’s taken off your taxes with much lower visibility if any of how much is your actual health premium!) Now let’s go back to FictionTown one last time. What if, with such a scheme set up, Steve goes, “yeah nah, we have a collective pot now, and they’ll pay out from that pot should something happen”, and ends up setting up a barbecue indoors, next to his book collection, or more likely knowing Steve, in his attached barn by the hay?! I’ll get to moral hazard another time, but the insurance industry, especially under the pressure of regulation to drive down costs, is incentivized to encourage and reshape entire industries around risk reduction: sprinklers, seatbelts, health screenings, all these you could say come about as a consequence. While insurance companies are there to help manage risk, just as you and me, they’d rather avoid the calamity from materializing than pay out post facto. There is a saying, your greatest well-wisher, wishing you a long and healthy life, is not your spouse, not your doctor, not your children, but your life-insurance provider!
