Medicare Kills a Program


I can't refind the link now, but the groundbreaking research on this involved looking at probates and court cases in 18th century England and how pocket watches filtered quite rapidly to the working classes, even though they were proportionally still very expensive. This is the closest I can find:

Bling culture avant la lettre. It vindicates Virginia Postrel et al on the substance of style, etc.
The problem with your PSST story (I always read this acronym as PTSD) is that it is so vague it's the type of theory (really a conjecture at this point) where nearly every observation can be rationalized.
I could just as easily tell stories about preference shifts; technology shocks; institutional change; human capital accumulation allowing for greater specialization etc that would be observationally equivalent to your PSST story on this matter.
