The Theory of Aggregate Investment in Closed Economic Systems

Although economic theory has increased our understanding of some economic problems, it has rendered others, including the problem of capital accumulation, growth, and development, more difficult to understand. Focusing on capitalist economic systems, this book develops a theoretical approach to the study of aggregate capital dynamics. The theory is developed within the Keynesian framework of aggregate thinking and builds on the work of such Cambridge economists as Robinson, Kaldor, and Pasinetti. The approach helps to resolve some theoretical difficulties within the Keynesian framework for studying aggregate investment behavior. Dompere also provides a criticism of the neoclassical investment theory and the general neoclassical theoretical framework for studying aggregate capital accumulation, investment, and growth. Reexamining some questions on investment that earlier theorists have tried to answer, this study develops some of the basic ideas of Keynes, Robinson, Kaldor, and Pasinetti into a general theoretical system that allows an optimal aggregate capital and investment to be determined for a given information set.
