Deflation
On savings and investments

Deflation can discourage private investment, because there is reduced expectations on future profits when future prices are lower. Consequently, with reduced private investments, spiraling deflation can cause a collapse in aggregate demand. Without the "hidden risk of inflation", it may become more prudent for institutions to hold on to money, and not to spend or invest it (burying money). They are therefore rewarded by saving and holding money. This "hoarding" behavior is seen as undesirable by most economists. Friedrich Hayek, a libertarian Austrian-school economist, wrote that:

It is agreed that hoarding money, whether in cash or in idle balances, is deflationary in its effects. No one thinks that deflation is in itself desirable.
