Capital, Accumulation, and Money: An Integration of Capital, Growth, and Monetary Theory is a book about capital. A root concept of capital is developed which allows for most existing concepts of capital to be unified and related to one another in consistent fashion. Such a root concept of capital offers a framework for integrating monetary and capital theory, and for analyzing the functioning of an economy, whether that economy is in a steady state of subsistence or in a process of sustainable growth. Specifically, it is shown that a conservation principle emerges that both implies and imposes a variety of constraints on the macro behavior of an economy, constraints which make for straightforward understanding and analysis of such concepts as the real stock of money, real-balance effects, and the general price level. New and illuminating insights are also provided into aggregate supply and demand, natural and money rates of interest, the relationship between real and monetary economies, and economic growth and development.
