The hoarding rises the interest rate (because is not part on the supply of savings in the financial market) and also makes prices drop.
If the ratio between "hoarding" and spending stays the same, the (real) interest rate stays the same too, irrespective of how exactly the hoarding occurs. The nominal interest rate might change while the hoarding ratio of money shifts, but after the shift is over, it will go back to what it was. The shift must at least stop when people shift all the hoarding from other highly liquid goods to money.
The more money is hoarded, the less money is left for exchange.
I think you might be mistaking the first and second derivation. It is the second derivation that causes macroeconomic changes, not the first one.
Your merchant must have a small stock to not go bankrupt with 50% deflation. The bigger his stock, the more he losses daily due to the falling prices.
The stock turnover is just a business decision like any other. I used similar numbers that I recall from textbooks during my studies, stock being 1/6th of annual sales. But I admit that might not be reflective of all businesses, my wife told me the company where she works has a stock 6 times the annual sales.
And your merchants are not using borrowed money. What interest rate do you use for the stable prices case and what rate for the 50% deflation rate?
If this was a real economy, then obviously the interest rate of the deflationary currency would be lower, reflecting the business profitability. The business profitability determines the interest rate, because that's when there's a balance between supply and demand.
By the way I wasn't using "stable prices", I compared a "deflationary" (50%) and an "inflationary" (3%) currency.
I wouldn't have understood the issue before either, even though Krupa, deSoto and others described the theory. Only after doing my simulation I understood it. While you are correct that in a scenario with a falling price level the nominal profit is lower, but the real market value of the resulting capital is higher. Absent taxation under legal tender laws (and the business cycle), the interest rate would be expected to reflect that so that the decision for a loan would be indifferent to the currency, but with the combination of those two, I think it would penalise loans in the appreciating currency if it wasn't legal tender.
It is a lack of demand caused by money that doesn't move. By hoarding you cause a lack in demand. You gave something but refuse to take something from the supply as compensation, there's lots of wares waiting for you in the market but you make the wares wait and rust. Unemployment is just labor (another ware) perishing in the market.
Again, I believe you are mistaking first and second degree derivations. If the price level changes predictably (e.g. second degree derivation is zero), then there is no shift, i.e. the equilibrium stays the same.
You can define velocity very accurately. I don't get your point about it being an abstract concept. What changes that?
You can define it, that's true, but velocity is not what influences the decisions of people.
Furthermore Bitcoin has a velocity far below normal money. Based on Cumulative Bitcoin Days Destroyed, on average a Bitcoin was spent about 0.8 times, and that does not even adjust for certain forex operations that occur outside of exchanges, and intermediate production stages. I vaguely recall from papers I read that "normal" money has a velocity of between 1-2, while some of the LETS systems have even 40 or 60. Do you see any problems with obtaining Bitcoins, shortages or other signs that there is "not enough of them"? No. Because the price adjusts quickly and there result is a reflection of the consumer demand. There's no problem here.
Furthermore, since June last year, the CBDD-based velocity has been falling, with a small exception of a period of a couple of weeks in November, and a couple of anomalies randomly occurring and lasting a couple of days. Yet between June and November, the price was falling, and since then it's been growing. There were no supply side shocks. So what happened? Demand side changed, and price reflected it.
For the consumer, velocity is irrelevant, he has no way of making a relationship to that concept.
Deflation reinforces itself until it disappears. Changes in demand should be from certain products to other products. Not from certain real products to money, that is, to nothing real. If demand changes from existing to not existing, that lack of demand hurts the economy. If the demand changes from one place to another, it only makes the economy change responding to the new wants as you describe.
I agree that decisions should be based on connections between real products. But that does not mean that all businesses should survive. An economy where everything is booming is not necessarily a healthy economy. On the contrary, changes in the money supply alter the ratios between the prices of goods, and distort the price of capital, causing wealth increasing projects to appear unprofitable, and vice versa, wealth decreasing projects profitable.
You're basically arguing for a perpetual boom. But that's not possible, it requires an exponentially expanding money supply. Eventually, it will turn to bust. For example, some sudden event might trigger the reverse, or the capital would run out (and people start starving) or the production costs of money would fall below their market price.
If you don't accept that with deflation (without demurrage) there will be less trade and businesses will make few sales paid for in the deflating currency, my question is not that relevant.
I can only repeat that you're confusing first and second level derivations.
At least I think you can agree with me that borrowers would prefer a non-deflating currency for their loans, right? Investment can still happen in other currencies giving them a competitive advantage over the deflating money, contributing to the disappearance of that deflation.
In the absence of taxes and legal tender laws, the decision would be currency-indifferent, it would equilibrate at the same real interest rate.
The point still is that with a free monetary market deflation is not really dangerous for the economy as a whole. That happens with monopoly money deflation.
It's even more specific than that. It happens during unpredictable deflation, for example like the one we're experiencing during a credit contraction.
But it's not like the falling price level of Bitcoin would suddenly appear out of nowhere, without anybody expecting it. Unlike the Spanish Inquisition, an appreciating Bitcoin is expected.
