One exception to this rule is given by the Austrian School of Economics whose major exponent is Ludwig von Mises. However, nobody speaks about the role of the monetary system in all of this or, more specifically, whether the kind of money that we use has any effect in economics. The official explanation is that the economies in this world are subject to cycles of booms and busts that happen more or less regularly and are inevitable. What was the origin of the financial crises such as those in 19? Are they really inevitable? - a natural feature of a free-market economy? Or are they avoidable? and if so what can we do to prevent them? This book is the result of the author asking some basic questions about the economic crisis in 2008.
