This book analyzes the important contributions of Rosa Luxemburg to economic theory as well as devoting some space to her background as a left social-democratic politician and her personality. The book's main focus of attention is the theory of capitalist development and the theory of the crash, but its connection with the theory of value, the theory of the monetary circuit, the theory of distribution and the theory of international finance are also explored. The contributors to the volume come from different theoretical perspectives, both from within and outside the Marxian tradition - Post-Keynesians, Kaleckians and Circuitists are all included.
