Economic crisis even more devastating
Historical deflation in some cases triggered the economic crisis even more devastating than hyperinflation. Deflation occurs when weak demand outpaces the market. With falling prices is also losing income from capital and labor. Companies must reduce or close, while workers become unemployed or must accept a lower pay. The falling revenues give a stronger effect on the decline in demand. At the same time increase the price also drop the value. With the general expectation of additional price, people will tend to stock up to fetch the potential wealth gains. The result can be a very large decline in production and consumption.
This happened with the economic depression of the 1930s. The situation then led to new break in economic theory. They recommended state intervention to boost demand in the economy.
