This just gets right back to the ZMP debate, right?
It's a real rigidity story, as I read it. But PSST is confusing to describe in terms of rigidities.
Nominal price rigidity is not the only mechanism that slows the adjustment of the real economy. Figuring out exactly how things have changed will take varying amounts of time and effort for the divers actors in the economy, due to both information availability and Bayesian-like mental model adjustment processes. There are many other real-world "frictions". PSST and ABCT both consider these effects and reject the idea of instant, cost-free adjustments (not only of prices). This makes these theories more realistic even if it distances them from Perfect Competition, General Equilibrium, or Hydraulic Keynesianism.
I'm going second Adam on this. ZMP explains why they are currently unemployed, PSST explains why they eventually get hired again.
