This book presents a study in the foundations of monetary theory with several unique features. It consists of two parts: a critique of the varieties of neoclassical monetary theory, and a rigorous statement of the foundations of Post Keynesian monetary theory. The two parts reflect Joseph Schumpeter's distinction between monetary theories in the divergent traditions of Real and Monetary Analysis. Part I offers a novel critique of Wicksellian and neo-Walrasian general equilibrium versions of Real analysis. The critique of Wicksell's monetary theory demonstrates the general impossibility of defining the natural rate of interest without which the loanable funds theory collapses. The critique of neo-Walrasian monetary theory, on the other hand, exploits the inessential role of 'money' in temporary equilibrium and overlapping generations models and develops a novel interpretation of the Patinkin controversy and the Clower finance constraint. The implications of these developments are then traced through the debates between monetarists and Keynesians. Part II presents a rigorous argument for securing the foundations of Post Keynesian monetary theory in the tradition of Monetary Analysis. In the context of the evolution of the monetary system from commodity money to credit money. Wicksell's natural rate of interest is replaced by Keynes's marginal efficiency of capital which is in turn applied to Myrdal's notion of monetary equilibrium to derive a formal definition of Keynes's point of effective demand. This leads to the most novel feature of the book: the demonstration of the existence of a long-run unemployment equilibrium without the assumptions of rigid wages. The principle of effective demand is shown to break Say's Law by placing a limit on the profitable expansion of output before full employment is reached.

Woodford (1997Woodford ( , 1998 employs an inter-temporal general equilibrium model to examine the properties of the monetary system as it evolves form the use of a physical medium of exchange to an electronic medium. He presents a structure in which cash (money) as a means of payment can be made to vanish at the limit but where he claims the price level remains determinate. It is shown that Woodford's analysis involves fundamental but still widespread conceptual and methodological errors. His general equilibrium model does not map into the world of electronic money and his analysis has no implications for the art of central banking.JEL Classifications: B40, E40, E42, E50

The system of equations governing the stress in a shear‐strained prismatical body are examined and it is shown that, provided the stress‐strain law adopts certain multi‐parameter forms, the system may be reduced to the Cauchy‐Riemann equations. Integration of the system is then immediate and the analysis of the stress concentration round certain notches thereby facilitated.
