Crises trigger attention in society and arouse our further interest, depending on the degree of the concern raised. In the recent past, this was the case with the financial crisis with the label ‚Great Recession‘ which started in 2007 in the USA. And as history shows, global crises are not isolated phenomena. They repeat themselves at indefinite intervals. Another well-known crisis is the Great Depression of the 1930s, and both represent two special examples that are familiar to economists in particular and sober contemporaries in general. The origin of both crises in the USA is obvious and opens space for some relevant commonalities in both events. The topic of this dissertation is based on a comparative crisis debate induced over a couple of years. In a first step the dissertation aims to evaluate essential parallels and distinctions regarding both crises methodologically via a comparative analysis and to illustrate the phenomenon of repetition that is their characteristic mechanism. In addition, the focus is on the accompanying fiscal policy circumstances of crisis management, which can be assigned to specific economic theories for each era. In the upper context there was always caution and fear that such events, which have jolted the economy as a whole, may be repeated. In fact, this is exactly the kind of situation we are in right now. With the so called ‚Corona Crisis‘ we have been experiencing a new crisis since the first quarter 2020. It will broaden the scope of the study. Based on observations presented in this work, explanations are suggested that crises are significantly related to the development of various indicators. In particular, it's about the impact of economic indicators like GDP, key interest rates or debt ratios and - as the Corona Crisis shows - supposedly unforeseen factors or shocks. The study deals with a comparative analysis of indicators regarding the three mentioned crises, with the aim of identifying trends or patterns to use these insights as a support for the birth of further crises. The work aims to provide a contribution to current crisis research in a comparative context and to advance findings in the field of early warning, crisis education and recommendations for future crisis avoidance.
