Raw LLM Responses

Is there research being done? Yes, performance management / talent management is an area that is constantly being reviewed, tweaked, and improved. Do all companies take a modern approach? Nope, not necessarily. And yes, the market plays a crazy role in all of this - and as I've mentioned in other posts, it sometimes makes sense to hop to another company (or two) to get the salary you want. The market allows this, even though it drives inefficiences. And yes, you're right about flight risks, turnover, and the lost domain knowledge. In many (but not all) cases, HR is aware of all of this. They often focus on the "super" critical key talent and offer retention bonuses there, but not for all key talent. To add to this, nobody wants to get into a bidding war if an employee is threatening to leave. That can get messy. To answer your question at the end, the market allows for so much volatility and nobody has solved this yet. There's also a belief (especially in Silicon Valley) that it's good for people to transfer between companies frequently. In theory, they are learning SO MUCH in each role and they're building a huge portable knowledge base in their brain.
