Deflation, an economic inconvenience or a serious problem

Economic deflation refers to a decline in general price levels, often caused by a reduction in the supply of money or credit.

Deflation can also be brought about by direct contractions in spending, either in the form of a reduction in government spending, personal spending, or investment spending.

Deflation has often had the side effect of increasing unemployment in an economy, since the process often leads to a lower level of demand by people for products in the various economic areas.
