This book provides an introduction to basic as well as advanced macrodynamics, viewed as a disequilibrium theory of fluctuating growth. It builds on an earlier attempt to reformulate the foundations of macroeconomics from the perspective of real markets disequilibrium and the conflict over income distribution between capital and labor. It does so, not because it seeks to support the view that this class conflict is inevitable, but rather from the perspective that an understanding of this conflict may help to formulate social principles and policies that can help to overcome class conflict at least in its cruder forms. It is further hoped that such an understanding can even lead to rational procedures and rules that may turn this conflict into a consensus-driven interaction between capital and the employable workforce.
