It takes awhile for people to change their view. If you come from a society that has for thousands of years said women couldn’t do jobs like be a lawyer as well as men, it’s not crazy that it would take you 40 years to figure out that wasn’t true.
It’s not a bad foundation when it comes to something like what we’re discussing, allocation of capital by professional investors in the medical space. They’re pretty close to homo economicus, but they’re still human so they still err.
The time limit creates incentive to go to market. Let’s say a company invents and patents a cure for cancer. If they just sit on it, they’ll get zero revenue, zero return on the cost to discover it… and then in 20 years their competitors can all use it for free. Not a sustainable business model—intentionally.
If behavioural economics or political economics were taught instead, anything with models that have explanatory power it would be viewed as lefty and revolutionary, and that would really upset donors. Consequently we are stuck with homo oeconomicus.
