This is the first full-length survey of current work which examines the compatibility of microeconomics and macroeconomics. Its particular distinction is that it makes accessible, to non-specialists, those extensive modern refinements of general equilibrium theory which are linked to macroeconomics and monetary theory. Part I traces the development and interlocking nature of two scientific research prgrams, macroeconomics and neo-Walrasian analysis. The five chapters in this part examine general equilibrium theory, Keynes' contribution, the 'neoclassical synthesis', and the Clower–Leijonhufvud contributions to questions of systemic coordination. The four chapters of Part II place recent work on the micro-foundations of macroeconomics within a taxonomic scheme of Walrasian equilibrium, Walrasian disequilibrium, Edgeworthian equilibrium, and Edgeworthian disequilibrium. Part III, a single chapter, provides an overview of the subject and ventures some conclusions.
