This diploma thesis is trying to describe implications of current financial crisis by the Postkeynesian and Austrian view. The introduction section focuses on course of events in the United States of America after the September 11 attacks on World Trade Center till outbreak of mortgage crisis in 2007. After 9/11 the Federal Reserve System started to unprecedentedly increase the money supply. Large amount of these new resources flowed to the real estate market. Incurred conditions and implications to other financial sectors till the bankruptcy of Lehman Brothers in September 2008 are thoroughly studied. The causes of the crisis are being looked through the Postkeynesian and Austrian perspective in this thesis, because the major representatives of these two economic branches were able to predict the crisis coming. By using the works of the Postkeynesian and Austrian economists, possible solutions how to avoid this negative economic event in the future are being mentioned in the final part of this diploma thesis. Their suggestions and proposals contrast each other. Nevertheless I reach certain recommendation here, which shows government's interventions are inappropriate and functionless. These interventions have also harmful influence on the free-market economy function. Moreover they tend to deepen recessions. These arguments are being demonstrated on real cases.
