Earlier quoted context omitted.
For drugs that are monopolies, tariffs actually don't impact the end price and hit the producer. In the short term, for drugs that are already on the market. In the long run, it reduces incentives to develop drugs. Tariffs are a tax on consumers for commodities but not for monopoly products.
So the assumption is they take the hit of 250% and just keep providing the US with these unique drugs when the US is "only" at max 20% of the total market? Afaik even less the more specialized drugs get. Edit:// it's not just me. Swiss media does barely seem to understand anything anymore either
Yes, monopolist will still want to sell because they still make profit. They don't take a hit of 250%, their profits are just reduced by ~2.5x.
US has famously high drug prices due so cutting edge pharma makes much of its profits there.
This is all standard 101 International Economics, Paul Krugman has written the standard textbook for it, it's a fun read.
