Since the world financial crisis of 2007 / 2008, it has become clear that financial crises and the major economic downturns they cause happen neither just in distant countries nor in the distant past. They are part of the economic realities of developed countries in the present. In the second Public Paper, the author presents the latest academic insights into the history of financial crises. What can we learn from the past when it comes to defining strategies and policies for dealing with financial crises? Why is the optimal number of financial crises not zero? You will receive the answers to these and related questions from Prof. Joachim Voth, a leading specialist in financial and economic history.
