That's a genuinely interesting point.  The only one I have heard of is 1870s US, but I don't know enough about what was going on at the time to make up my mind whether deflation contributed to these things, or whether these things happened despite the deflationary environment (don't take this as a statement either way, I genuinely don't know).  Out of context, I can't make up my mind (e.g., there are inflationary periods where investment and consumption have gone down, despite the pull of inflation in the opposite direction).  Can you point me in the right direction to learn about these episodes?
