More on the Myth of the Macroeconomy

What Got Us Out of the Great D... You Should Be Nodding Your Hea...

From a speech by Electronic Arts CEO John Riccitiello, reported by Andy Katkin.

I see an unfortunate gap between the economic performance of key parts of the tech sector, and the rest of our economy. I see two economies on such radically different trajectories that it's hard to believe they co-exist in the same country.

In tech -- Silicon Valley, North Carolina, Austin and Boston - we are witnessing the most dynamic period of creative destruction and economic construction in history. And that construction is creating new and very high paying jobs.

Economic disruption is a constant everywhere....but today in tech, economic cycles turn, not over multiple years, but in months....large companies and fortunes are built, erased, and built again with frightening speed.

In tech, the most impressive and profitable operations are constantly being destroyed...and replaced with even better businesses. And these businesses are hiring a rapid pace. Job openings exceed the number of qualified workers and wages are skyrocketing. And companies with only a few years in operation are assigned multi-billion dollar valuations.

Thanks to Nick Schulz for the pointer.

Also, Tyler Cowen links to a paper by David Autor and others that looks into the way trade with China affects specific labor markets. (This is actually a revised version of an earlier paper.)

If "labor" were a homogeneous, fungible aggregate, we would see unemployed manufacturing workers taking the high-paying jobs that tech companies are having difficulty filling. Thus, the assumption of a single labor market is clearly false.

Even in the DMP type of search models, this sort of structural mismatch is not found. It is as if there is a "matching technology" that can fit blue-collar pegs into high-tech holes, but the process takes time and effort.

A macroeconomist would argue that structural unemployment always exists. It represents a sort of background noise. Models that assume a single aggregate labor market are only approximations, and if the economy acts as if there were a homogeneous labor market, then this approximation causes no more harm than any other simplifying assumption in economics.

It's an empirical question. My view is that the variation across sectors and occupations is more dramatic and important than the variation within sectors, even for the period 2007 to the present. That is, for some fairly large categories of workers you will see a higher unemployment rate in 2007 than for other categories in 2011, because the structural factor swamps the supposed aggregate-demand factor.

I'd love to believe this. It certainly rings true with my experience, as my (Boston-area software industry) company is totally berserk trying to find any competent people to work here and my phone is ringing constantly with increasingly rabid recruiters.

But there's more to it --

  • The owner of the pizza-and-subs place around the corner from my house is tearing his hair out to find competent delivery drivers and line cooks.
  • Commercial space off of main streets is going empty -- but commercial space rents on main streets are through the roof.
  • Mortgage brokers -- MORTGAGE BROKERS! -- are so understaffed they can't even start new refinances.
I don't know if this is a revolution of raised expectations (did we used to settle for less competent restaurant delivery? Did everyone decide their offices needed to be in nicer places?) or systemically inelastic supply or just a lot of people and things being in the wrong places. But a lot of things are tight on the market that aren't senior software engineers right now; a theory of the economic mess needs to explain how it can be hard to find grill cooks, not just techies.

In part, it is that the price the employer is willing and able to pay is less than the opportunity cost that accrues to the potential employee if he took the job.
