Hosting the online #aea5k awards yesterday was really fun, and I guess I’m ready to admit that *maybe* live video production has somehow evolved from “thing I’m committed to being good at for professional purposes” to “OK fine, this is also a hobby.”

Here’s how I did it. 1/
As I wrote last year in a similar thread: “Stuff went wrong, and if you want this done right you should get a pro. But I’m trying to learn and it’s fun to be part of a community effort.”

Key tech was @Blackmagic_News ATEM Mini, @Raspberry_Pi, @Zoom, @Restreamio, & @heretorecord
I ran the show through a @Blackmagic_News ATEM Mini Extreme amzn.to/3mW47P8

A few years ago, this stream wouldn’t have been possible for less than many thousands of dollars

Basically this mixes various (audio and video) sources and streams directly in hardware (no OBS)
Sources:
- My camera (behind the teleprompter) and mic
- @dbergstresser via Zoom running on a second laptop
- Graphical overlays (ticker, selected YouTube comments, timer) from @heretorecord Graphics running on my laptop
- All the recorded videos played on a @Raspberry_Pi
Prerecorded videos (including @cameron_pfiffer on piano and the award presenters) converted using Handbrake* were on Raspberry Pi running @videolan VLC*. The ATEM switcher and the Pi were controllable using the amazing @bitfocusio Companion*.

*Open-source
Learning this stuff has involved help and advice from friends including @heretorecord, @aaronpk, and @thomas_cantrell. Thank you! 🙏
These #AEA5K awards are kind of my hobbyist Super Bowl and I’m proud when I compare to last year’s show👇

That said, I’m looking forward to running IN PERSON next year!
Another thing: I’m proud and have fun posting this stuff, but I am always nervous that I may scare people off from making the SIMPLE investments (human capital, physical capital, and labor) in online-teaching-tech.

Inada conditions apply and MANY of you are on the steep part…
A $60 USB mic and a $15 boom arm to put it close to your mouth will do wonders.

A few thoughtful hours with @danmlevy’s book will do wonders.

Excited for @BabsonFinance seminar on a cool new paper by Hadlock, Jing Huang (E&Y), Paul Obermann (U Alabama) and Joshua Pierce (U Alabama)

New data on S&P1500 division mngrs matched to segment performance. Connect managers to their CEOs (schools, prior employers, social orgs)
Managers who are connected with the CEO:
• MUCH less likely to depart/more likely to get promoted
• No performance–dismissal sensitivity (it’s there for the unconnected)
• ≈ Same for hired vs. inherited connections!

Good for the shareholders? Hard to say but…
…looks like this “friends-with-benefits” situation is bad:
• Outside labor market outcomes after departure much poorer for dismissed connected managers than unconnected (the “retread” market)
• Appointing connected managers not associated with performance improvements

A Twitter story

Act I. I see this tweet👇 and DM old friend @ben_golub saying “yeah, that’s definitely not right, the seller would just invert Zillow’s signal, etc,, but I don’t want feel like a late night fight with a big account.” Ben’s like “I do.”
Act II. Turns out that while OP’s original post implied seller’s 𝘦𝘴𝘵𝘪𝘮𝘢𝘵𝘦 𝘰𝘧 𝘷𝘢𝘭𝘶𝘦 was N(1,s) but instead solved as if seller’s 𝘳𝘦𝘴𝘦𝘳𝘷𝘢𝘵𝘪𝘰𝘯 𝘱𝘳𝘪𝘤𝘦 were N(1,s), per this tweet👇

Bayesian updating: when will they ever learn?

As usual, a great volatility explainer thread from Benn👇. It’s true that the market and VIX *usually* have a negative relationship. (The market tends to fall faster than it rises, there may be more hedging demand during downturns, …) But… 1/4
… markets *can* rise quickly, and volatility—both realized and implied—can be high during rallies. As it is now!

The relationship between VIX and the market is NOT always linear. Not even close. However, if you started paying attention recently… 2/4
…the (negative) VIX–market relationship probably looked *very* linear. In fact, as of ten days ago, the linearity was arguably the strongest it had *ever* been in the VIX’s 30-year history!

But that was ten days ago. Things change, and… 3/4

OK folks. Here’s my thread on technology for teaching online.🦠 I’m not an expert, but I’ve got some thoughts.

My goal is to cover a few things you might consider if you’re trying to quickly get an existing course online. And my focus is on technology, not pedagogy. 1/
Plan:
① Streaming/recording software
② Basic hardware
③ Presentation software
④ Advanced hardware
⑤ Tips and tricks

I’m not going to cover discussion forums, homework, etc. Your students probably already use an LMS (Blackboard or Canvas) and I’d stick with that for now. 2/
① STREAMING/RECORDING SOFTWARE

Key question is teaching synchronously (live) vs recorded.

Synchronous teaching should still get recorded for later, but ANY live viewing—and especially live interaction—requires particular software.

Recording? You have much more flexibility. 3/

Suppose you had a side hustle catching snails on the weekend and delivering them to a restaurant catering to French tourists. You’d love to get some sense each Saturday of how many tourists are likely to arrive over the next week so you know how much time to spend snailing. 🐌 1/
You’re in luck: It turns out that there’s an arcane organization (the Coalition of Bakery Oven Examiners, or CBOE) who publish just such a forecast, called the FIX (i.e., the “French visitors IndeX”). Their forecast isn’t perfect, but it’s on their website so 🤷‍♂️. 2/
What does this have to do with baking? Who knows and who cares?! You’ve got your forecast and it helps you with your snailing.

But then you get an idea for a new side hustle. The French go on vacation in August. The FIX will go up then. You can predict it in advance! 💰 3/

Heading in to our first session at the 2020 Financial Reaearch Association conference; live-tweet starts now. (If you’re not interested, please 48-hour mute hashtag #FRA20 ). Program with paper links is here: fraconference.com/current-progra…
…and if you’re eager to get going early, here’s my #FRA2019 thread from last year: #FRA20
First paper is on cash windfalls and wages (by Sabrina Howell and J. David Brown; presented by Cesare Fracassi).

Lots of papers ask what happens when firms get cash windfalls. Paper uses SBA-provided Small Business Innovation Research Grants (~$2.2B/yr). #FRA20
