Is Macroeconomics a Science?

This paper was written as the first draft of the invited Foreword for the book, Money and the Economy, by Apostolos Serletis. The paper provides a critical view of those areas in which methodology in economics deviates from that in the physical sciences, provides examples and illustrations of those deviations, and emphasizes those areas of and approaches to economic research that most closely correspond with the nature of research in the physical sciences
