I have mixed feelings about today's daily. I feel that most of the points are weak except for #3 which is a very important insight IMO. Just like a depreciation of 3 percent per year of money doesn't affect savings that much, deflation wouldn't do too much either. While I believe that any drastic, and especially any radically unforeseen shift in market data will cause problems, a steady deflation rate shouldn't be too bad, and it would likely shift the production structure further outwards in time.
If deflation occurs as a result of increased efficiency then relative profit margins adjust just fine, if deflation occurs due to an increase in population then demand curves need not shift as such. P may decrease, but Q will likely increase proportionally, helping the adjustment.
Dave helped me to see this here, although there's still more thought I need to put into the matter.
