Google's John Mueller has said that it is best to have an expert write or review your content for the YMYL (your money, your life) types of categories of web sites. In fact, John Mueller went as far to say that when a doctor reviews your content, you might want to label that content as been reviewed and by whom. But Danny Sullivan implied that renting these people's names won't necessarily help.
Danny Sullivan from Google said on Twitter "It doesn't work like that." When someone said to him "I am seeing a growing number of sites who are "renting" specialist's names in EAT segments to add to the bylines in order to add authority to their content."
Here are those tweets:
It doesn't work like that.

Update: Here is a tweet from Danny saying the advice Google has been giving has been misinterpreted:
I think the advice is misunderstood. People should aim for great content. Experts can help produce that. But we don't know a particular expert has written anything. However, if you have good expert content, that might produce the types of signals we find correspond with such.

The rest below this line is not updated but from the original story:
So you have a medical health site and you are paying Doctors to "rent" their name but now that fee is worthless?
What are we doing?
The content has to be authentic, unique, genuine and real. Google can tell if it is written by an expert, Google can just tell. Not because it has a name on it per-say but because of many other signals Google picks up on.
