Jeff Kaufman discusses an interaction between price controls and emergency preparedness:

Let's say you see a potential pandemic coming, and you produce a product that could be critical. Maybe you make respirator masks, maybe you make ventilators, maybe you make PCR test reagents. You can see that if you and your competitors don't ramp up production and the pandemic happens, there will be a shortage. What do you do?

[...]

[One] option is to ramp up production now, speculatively. Start paying workers extra to work longer shifts and run your assembly lines around the clock. Train extra workers. Find what you're bottlenecked on and figure out how to get that ramped up too. If the pandemic fears were overblown you lose a lot of money, but if the pandemic happens people need what you have so much that you can charge high prices. How much to ramp up production in advance depends on how likely you think the pandemic is, and how much you'd be able to increase prices if it does happen.

Except we have laws and customs against price gouging: if the pandemic does happen, you are going to have a lot of trouble raising your prices. The laws generally do allow passing along increased costs, but the problem here is that your costs were speculative. Let's work an example. (...)

The punchline of the worked example is that if you think that there's a 50% chance of an emergency that will make your products ten times as valuable, it's still not worth it
