In ordinary markets prices fluctuate up and down fairly randomly as typically observed in foreign exchange markets or in stock markets. Inflation is the special economic situation in which prices apparently move monotonically upward and the value of money decreases rapidly. There are many examples of inflation not only in the history [1] but even now some countries are facing with the fear of inflation. Especially so-called the hyper-inflation is a kind of breakdown of currency system devastating the whole society.
