Does construction ever get cheaper?

from Construction Physics [alt+shift+b] in architecture

I've mentioned a few times that I generally prefer looking at construction progress through the lens of cost indexes rather than productivity indexes. Whereas productivity indexes try to track changes in the amount of construction we get for a given amount of labor (for labor productivity) or labor + capital (for TFP), cost indexes try to track changes in how much construction we get per dollar. Cost indexes don’t measure the absolute cost of construction (in, say, dollars per square foot), but relative changes from a particular reference year.

Seemingly Out Of Context

Given the vast numbers of commuters that the Long Island Railroad carries, It’s easy to forget that it also carries freight. From a couple of years ago, a view of tracks elevated above Glendale, Queens, as a freight train with a much-grafittied hopper car goes by some brick bow-front rowhouses:
