Experimental #EconTwitter, here's an open question about mechanism design that lab experiments could answer. There's been an explosion in formal standards for what counts as a 'simple' mechanism. Do these in fact predict subject behavior? (1/N)
See e.g.

My JMP gave some evidence that one of these concepts (OSP) has some empirical support in auctions. It predicts, for instance, that subjects will make mistakes in second-price auctions but not in ascending auctions. But what about other settings? (3/N)
There are now known OSP mechanisms for matching with single-peaked preferences (Bade JET 2019), voting (Arribillaga, Masso, and Neme, JET 2020), allotment rules (Arribillaga, Masso, and Neme 2019), belief elicitation (Tsakas GEB 2019), and many more (4/N)
How do these theoretically-simple mechanisms perform in the lab? What's true of human behavior that the current crop of formal simplicity requirements miss? (5/N)
I'd write these papers myself, but think that it's better if theory-generation and theory-testing are at arms-length. But we need new data to generate better theories! (6/6)

One reason why grad students find it tough to do economic theory: It takes courage to make wrong guesses. For (most) problem sets, you know ahead of time that your target theorem is true and provable. For real research, you have to guess. (1/N)
Most theorems worth proving are ex ante implausible. If your guesses often turn out right, you should aim higher. You need the emotional fortitude to make conjectures and work under uncertainty, knowing that most conjectures are wrong. (2/N)
Crucially, you often only discover whether a model is fruitful by working on the model - which means making guesses and trying to prove them or find counterexamples. Even wrong conjectures can be productive! (3/N)

Many of us were brought up in homes where upon making a mistake/ upon perceived to have made a mistake, part of the punishment, apart from being beaten, denied food, shouted at, and told not to cry after being beaten, was to be given the cold shoulder for a time.
And there's a name for that cold shoulder: Silent Treatment.
Especially when we grew a bit and it was getting awkward to get a beating, like, say, in your late teens and early 20s, silent treatment became the go-to punishment from parents/guardians/caregivers.
Or, when your parent/caregiver/guardian couldn't beat you because it would get them in trouble - {cue in aunties, mums, nannies, older cousins, other relatives living in the household and taking care of you when core caregivers are away} - then silent treatment was the main way

1. It's interesting as a rough measure of what most people think the word #design means to search various systems and see what comes back. Here's Amazon Prime Videos. Mostly interior design and remodeling living spaces.
2. Netflix, Hulu and most video services I've tried return mostly the same kinds of results. User experience and UX return almost nothing. The one hit I got for #ux on Amazon Prime was this (although some user experiences are like defusing bombs!)
3. Searches on Google and Bing unsurprisingly return similiar kinds of results: definitions, logo making apps/services and interior design - and TED and WIRED are often in top 10 or 20 results. Not sure what to make of that.

So I've only been on Twitter for a month... and I've learned a couple of things. For students interested in utilizing this platform, here is a thread on how I engage with #EconTwitter - anyone can jump in with any additional thoughts or tips. 1/
1. Ask thoughtful questions. Honestly, the tweets that have sparked the most discussion are the ones I have posed as questions. Questions invite dialogue and thus interesting responses. 2/
2. Highlight, but don't spam, seasoned professors/professionals that genuinely inspire you to pursue your desired career path. I gave shoutouts to @aadkuia and @dynarski, which has led to conversations that have been helpful to my growth as an aspiring economist. 3/

Here's a lazyweb question cause I can't easily find the answer:
The Osborne 1 originally shipped with single-density single-sided 5.25" drives, then later switched to double-density, with a free upgrade for existing owners.
But how do you tell which density you have, SD or DD?
I mean, short of sticking a DD disk in it and seeing if it works.
There's some fun stuff in the upgrade manual: the upgraded drives might not be able to read the single density disks.
This isn't due to any problem with double density, just that it might be aligned properly now and the previous disks were misaligned.
