Ask HN: What have academics who study entrepreneurship learned?

I see a lot of startup advice combing from founders who've walked the walk, accelerators like YCombinator, and platforms like Indie Hackers. However, I also know that there are academics who study entrepreneurship.

Maybe I'm just not hanging out in the right corners of the internet, but I rarely see things coming from them. Two questions: 1) What are the important things they have learned? 2) What are some good resources for learning more about their findings?
