alt Hacker NewsThis is the same problem with cost-plus contracts in the military. In theory, capping profit is meant to reduce profiteering. But in practice, if your profit is fixed at 6% of the cost to built a jet fighter then you're incentivized to make that jet fighter as expensive as possible. The way to maximize profit under a cost-plus regime is to maximize the cost.
I will piggy back off of your comment because I was going to say a very similar thing. In my state, electric utilities are guaranteed a rate of return on investment of approximately 12%, if I remember correctly. And so there's a lot of incentive for build out and maintenance that's high in total dollar amount and high in volume of work done. In some ways it's the system working as designed but the "cap" can incentivize erroneous build out, as you noted in the jet fighter example.
