Exploring the characteristics of inflations and comparing historical cases from Roman times up to the modern day, this book provides an in depth discussion of the subject. It analyses the high and moderate inflations caused by the inflationary bias of political systems and economic relationships, as well as the importance of different monetary regimes in containing them. The differences for the possible size of inflations among monetary regimes like metallic currencies, the gold standard and fiat paper money are discussed. It is shown that huge budget deficits of government have been responsible for all hyperinflations. This revised second edition debates whether a growth of the money supply exceeding that of real Gross Domestic Production is a necessary or sufficient reason for inflation and also includes a new concluding chapter, which explores the long-term tendencies to create, maintain and abolish inflation-stable monetary regimes. Moreover, the conditions for long-term inflation-stable monetary regimes in history are explored.
