What happens when a skill you have becomes obsolete? No, this isn't a R vs. Stata thread---it's a thread about a working paper w/ @sonnytambe!

The skill we look at is Adobe Flash, which @apple decided to no longer support back in 2010, which in turn caused demand/interest to plummet, as measured on @StackOverflow and in online labor markets, one of which is our empirical context
Despite the big fall-off in Flash jobs posted, very little else appeared to change in the market for Flash skills: wages for Flash jobs didn't fall, jobs didn't become easier to fill & openings weren't inundated with out-of-work Flash programmers
What happened was that (a) new entrants stopped specializing in Flash and (b) at least some existing Flash specialists started moving to other skills. In short, the demand shock quickly became a supply shock
At the level of the individual Flash worker, using a matched sample, we find (a) no fall-off in their wages, (b) some decline on-platform hours-worked. The most-focused on Flash workers had substantial increases in application intensity and a movement towards new skills
In short, despite Flash skills being expensive to acquire, workers abandoning a skill with no perceived future create a de factor highly elastic supply curve, keeping wages "flat." We show how this is possible with a little toy model, of course.
We also conduct a survey of Flash workers affected by the decline. They confirm many of our stylized facts & give color to the adjustment process. For one, they report being highly-forward looking and market-oriented & deciding what skills to pick up
They also emphasize how critical on-the-job learning is to acquiring new skills. Sadly for us teachers, formal classroom learning gets almost no love
Anyway, lots more in the paper & thanks for reading this far- check it out! https://t.co/w6nLf1tnST Comments, feedback, suggested citations (even to/esp to your own papers) most welcome!

The Nashville Operation - A Battle in the War

A thread exploring the Nashville bombing in the context of the 2020 Digital War (via SolarWinds) against the United States perpetrated by our enemies, likely China, Iran and/or Russia.

SolarWinds Hack

A digital "Pearl Harbor" moment for the United States, whoever was responsible had access to the keys to the kingdom for months during 2020, including sensitive military infrastructure. This is war!

SunGard + SolarWinds

SolarWinds software company is owned by same company that owns SunGard, which essentially provides data center services. A secure place to host internet servers with redundant power and "big pipe" data connections.


SunGard Data Center

In Nashville, around the corner from their "big pipe" connection, AT&T. Like any data center, highly secure. Only authorized personnel can enter, and even fewer can access the actual server rooms. Backup generators are available in case of power failure.

If the SunGard hardware was being used to "host" critical command and control software related to SolarWinds, the US powers would be very interested in gaining special access keys that are stored on the hard-drives of specific servers.
