The nature of macroeconomics - Athol Fitzgibbons

This book addresses the long absence of a satisfactory theory of macroeconomics.
Keynesian theory is not consistent with rational self-interest, but neo-classical economics is unable to explain economic volatility and the trade cycle.
Athol Fitzgibbons critiques the leading macroeconomic theories, which he believes are unduly mechanistic because they are incompatible with non-quantitative knowledge.The author sketches the intellectual history of partial knowledge and judgement so far as these relate to macroeconomics, and rejects the claims that Keynes recanted the analysis of practical reason in his Treatise on Probability.
Fitzgibbons's theme is the possibility of a new synthesis of Keynes and the neoclassical system.
This stresses financial rationality, but it also recognizes that there is an element of indeterminacy in both government policies and the movements of the market.
