I'm still trying to get a handle on how people here are using it. For those that do, is having a reserve of resources distinguishable to you in any way from hoarding that resource?
What I mean by "hoarding" is basically just normal "saving" taken to an extreme.
So, for instance, if a bank is making no new loans and significant investment - if it's using its earnings to do essentially nothing but pay down debt, build cash reserves, and purchase low-risk assets - then that goes beyond normal saving and into hoarding.
It's not a quantitative difference; I'm just using the word to describe the concept of banks saving so much that it actually hurts investment and real economic growth.
