The Nature of Macroeconomics

Instability and Change in the Capitalist System

Athol Fitzgibbons

This book addresses the long absence of a satisfactory theory of macroeconomics.

Athol Fitzgibbons critiques the leading macroeconomic theories, which he believes are unduly mechanistic because they are incompatible with non-quantitative knowledge.

Monetary policy would therefore be completely ineffective because, as the quantity theory of money suggests, the price level would immediately change in proportion to the money supply. Likewise, and as the Ricardian equivalencetheory indicates, fiscal policy would have no macroeconomic effects in conditions of perfect knowledge. A ‘rational’ market would factor in the higher future taxes that would be required in the future to pay for any unfunded government spending, and the expansionary effects of a spending programme would be exactly neutralized by the prospective increases in taxation. Given tastes and perfect knowledge, any aberrant and individual actions in the market would be exactly and immediately offset by other individuals. A single item withdrawn from the market would be replaced by an identical item, and profittaking would mean that no decision-maker, government or private, would have any impact on the market outcome. However perfect knowledge is only one extreme; at the other extreme, if no one had any idea whatsoever of the general equilibrium consequences of monetary and fiscal policies, those policies could not be offset by market profit-taking. However such policies 96 The Theory of MacroeconomicPolicy 97 could never...
