p> The Austrian school defines deflation and inflation solely in relation to the money supply. Deflation is therefore defined to be a contraction of the money supply. Only a decrease in money supply can cause a general fall in prices.
Increased productivity, however, can appear to cause deflation; but it is not general deflation; as the price of produced goods falls, while labor rates remain constant. Austrians show this as a benefit of sound money, which increases or decreases very little in total supply. Prices should simply confer the exchange ratio between any two goods in an economy. Increased productivity generally means less labor for more goods, whereas increased money supply should mean the same amount of labor for the same amount of goods.
For instance if there is a fixed money supply of 400 kg of gold in an economy that produces 200 widgets, then one widget will cost 2 kg of gold. However, next year if output is 400 widgets with the same money supply of 400 kg of gold the price of each widget will drop to 1 kg of gold. In this case the general fall in price was caused by increased productivity. p> The opposite of the above scenario has the same effect on prices, but a different cause. If there is a fixed money supply of 400 kg of gold in an economy that produces 200 widgets, then once again each widget will cost 2 kg of gold. However, if next year the money supply is cut in half to 200 kg of gold with the same output of 200 widgets, the price of each widget will now only be 1 kg of gold. When capital profits are dropping rapidly, there is no reason to invest gold, which breaks the savings identity, and thus the automatic tendency of the economy to move back to equilibrium.
Austrians view increased productivity to be a good cause of a general fall in prices, while credit/money supply contraction as being a bad cause of a general fall in prices. Austrians also take the position that there are no negative distortions in the economy due to a general fall in prices in the first scenario. However, in the second scenario where a general fall in prices is caused by deflation, Austrians contend that this confers no benefit to society. For in this scenario wages will simply be cut in half and lower prices will not reflect a general increase in wealth.
Also, Austrians believe that some entity being able to inflate or deflate a money supply is given a privilege, as all prices will not change both simultaneously and proportionally. Rather price changes will occur as a response to what seems to be changes in demand, although this is only in nominal terms. Those who can inflate or deflate the money supply (or those closest to this source) can take advantage of an otherwise unknown change in the money supply by making exchanges that appear sound in nominal terms, but actually confer more profitable exchange rates in real terms, once prices have adjusted to the change.
For example, if a widget ...
