Deflation

If inflation is a bad thing, why not do the opposite?

Deflation is defined as an increase in the value of a currency, which increases the purchasing power of its holders and is represented by a fall in the prices of goods and services.

The reason why deflation would be a really harmful thing to be constant in an economy is because it postpones the consumption decisions of the players, slowing down the economy.

This is because, as prices are gradually reduced, an object that costs 1,000 today could be worth 950 tomorrow and 900 the next day. This being the case, and expecting prices to continue to fall, it is better to wait for the price to continue to fall than to buy it today knowing that it will be devalued and lose value immediately.
