Alright Machjo - I'll give it a whirl and offer my thoughts. I'm using this post to start.
RE: Bank rate set at 0%
I never suggested that it would solve all problems, but it is an effective way to counter deflation.
Your assumption isn't really correct here. Even if there were restrictions in who was able to access the cheap loans, the notion that lower costs may in fact compel more folks to purchase items that they may not have considered otherwise. Think about how many people were seduced into buying over-priced real estate based on the opportunity for cheap mortgages? The same goes for other capital goods like cars, furniture, electronics etc.
Those lower perceived costs will not force the cost of the goods down, rather, it may act to increase demand and potentially raise the prices - it is a response by gvt to stimulate the economy and generally that goes hand in hand with higher costs (inflation). Although we've addressed the defalation issue you identified - the genie is out of the bottle and the inflationary trend is promoted again.
Again - look to the experience that Japan had or even the USA when their treasury under Greenspan lowered rates to 0.5% - the results are not positive.
(... and in the event that his name elicits a response that he was under the Bush admin, please spare me the political partisanship - Greenspan is respected by the finance sector throughout the world)
RE: Printing more money
As I'd mentioned, as a counter-deflationary policy, which implies too things:
1. That it would be used only in the event of deflation, and
2. That it would be used only to the degree that it puts a stop to deflation.
Of course I'd oppose printing our way out of recession and would certainly oppose that.
I see your logic but the system is not that responsive or 'controllable'. Further, a nation's valuation of their money is, in part, based on the perception by other nations. In reality, nations control their money supply through buying and selling their currency on the international markets. When the dollar is too low, the feds will buy-up dollars on the open market and thus restrict the outstanding amounts in hopes that the (more) limited supply will increase demand and therefore the price. The opposite holds true for those times when the value of the currency is considered too high.
In terms of just printing more money, here's the example: Between WWI and WWII, the Germans had to pay reparations for their WWI antics. As the country was devastated by the war and their economy had yet to be rebuilt, one of teh strategies they attempted was to simply print more money and fire it into the system. The response was that no one wanted German currency. The result was that the local population (at its height) needed (literally) pillow-cases of money just to buy groceries.
