I'm not an economics student or anything like that, but I've had a question on my mind for a while now. Why don't insurance companies insure against recessions. Like if the economy were to downturn, you get a payout which can help your business survive longer without as many layoffs or maybe even weather the event.
Insurance companies in general exist to decrease risk, you pay them a certain amount of money and should some negative event happen they bail you out in a sense. They make money overall because the positive expectation of money paid from many people over time beats the negative expectation of the unpredictable event.
Even if the event has a huge cost, this just means insuring it should be more expensive. There are some close concepts like hedges which insure your stock investments against a downturn, but why can't I directly just pay to insure against the economy going down?
I can think of some explanations for myself. Like maybe it's because instead of the event happening at random across many actors, it tends to happen to all the actors at once. This means the insurance would need seriously large amounts of money on hand in case of such a large payout. But if this is the case, wouldn't it just explain why it would be expensive not entirely non-existant?
