A few observations based on limited data... A good friend hit everything right. MD/Phd on a full ride followed by a high-prestige post-doc that included international research. It took him until his late 30s to be comfortable financi

Entire fields of finance exist for this. Find the hole in the model, and stuff billions of bonds and derivs in it. This is especially an issue when the model sellers optimize off of it. Also a reason why it's good to be leery when pe

Ahhh. Sounds like he came back with some humility. Good for him!

I'm not sure I follow the story. He was fired or demoted? And now he's back as the CEO again?

I suspect that it's a trade of prestige for cash. If you're the president of any of those schools, the prestige follows you for life. You can always trade down on reputation for an increase in pay later. They will always have c

Interesting. Link? I see some suburbs winning and some losing but don't have an aggregate view.

Are you arguing that industries themselves don't exist? Yes, they are an artificial construct with very fuzzy boundaries, but you need to sort companies some way or another.

Is this the new model of urban decay? There is a large trend towards urbanism, but not every city is a winner.

It's also the timing of ideas. Many of these ideas flopped because execution just wasn't feasible at the time. Today, it's much cheaper to execute on ideas (people are moderately more expensive, technology infrastructure is

I didn't have any life changers, but I throughly enjoyed The Hard Thing About Hard Things by Horowitz. I've been turned off by the soft and cuddly management book industry because it only focuses on the bright side. Real work is

Yes - they're talking their book. Which would survive a VC funding round better: Two startups with a similar very far fetched idea - one asks for $10mm to continue in the valley, the other $5mm in Morocco?

I've seen academics fight harder for a new filing cabinet than bankers for a 500K bonus.

This is a bit of a divergence, but a fun way to practice what you learn is Project Euler, which will link it to your programming. https://projecteuler.net/ It's more of an applied problem set of increasing difficulty

I agree with all of what you've said. It's also worth noting that this is just 2% of the company. One person offering to pay cash for 2% of a company with seniority preferences is very different than someone offering cash for th

Your reaction was very similar to mind. I thought, "What benefit here is not available via functional programming?"

I think they overly downplay the effectiveness and efficiency of vanishing. I used to work with a VERY polished salesman, who was the king of making everyone feel at home at his events. He was an absolute gentleman. But you knew he would

I'm not a lawyer - is this a done deal? With FedEx they were working full time, right? If someone is driving for both Uber and Lyft, isn't it hard to say they should be an employee of one or the other?

Interesting that a lot of this is about "What stands the test of time?" Papers from 1994 to 2004 perhaps didn't have enough time to work their way through the system. What I find interesting is the gap of time between papers

True - it benefits Uber immensely from a tax perspective (and benefits?) for them to be independent consultants. It's also harder for independent consultants to unionize.

I can see the issue here. Someone says, "Why is this so hard on me when the company shuffling paper is making all the money?" I could see Lyft or Uber having a competitive advantage if they gave equity or something like equity t

Remarkably good ideas, and I tend to view most posts like this as Snake Oil. Almost everyone should be doing most of their equity investments through a passive low cost index like Vanguard's.

Thank you for your comments/thoughts. It's very hard to come up with a lot of these numbers. In the US it's possible to look at the aggregate corporate debt market, but you would still miss some liabilities. It doesn't

Thank you for the comments. Here's the point I'm making... Let's take an oversimplified view of the world. 1) In 2008 a company has $1 billion in stock value, no debt and goes belly up. 2) In 2009 a new company starts with
