THE idea that the dynamics of economic life in the capitalistic social order is not of a simple and linear but rather of a complex and cyclical character is nowadays generally recognized. Science, however, has fallen far short of clarifying the nature and the types of these cyclical, wave-like movements. When in economics we speak of cycles, we generally mean seven to eleven year business cycles. But these seven to eleven year movements are obviously not the only type of economic cycles. The dynamics of economic life is in reality more complicated. In addition to the above-mentioned cycles, which we shall agree to call “intermediate,” the existence of still shorter waves of about three and one-half years’ length has recently been shown to be probable. But that is not all. There is, indeed, reason to assume the existence of long waves of an average length of about 50 years in the capitalistic economy, a fact which still further complicates the problem of economic dynamics.

Of all fluctuations in economic activity, the long wave or Kondratieff cycle is easily the most puzzling and least understood one. Does it really exist, and if so, is it only a cycle in prices or a cycle in economic activity at large? What causes it, and has it been confined to Europe or does it affect the world economy as a whole? These questions, which seemed of little relevance in the prosperous years of the postwar growth era, have gained new importance since 1973. With the downturn of the long wave, interest in it has enjoyed a revival, as it did in the 1930s. A great number of publications on the long wave have appeared since 1973, many of which have added to our insight of what causes the recurrent alternations of growth acceleration and retardation. This book is the first in the English language in which all important long wave theories, old as well as recent, are brought together. It focuses on the long wave as an international phenomenon, affecting all industrialised countries. It contains new theory as well as empirical evidence and in the final section suggests a number of policy recommendations to generate innovation. This book offers an interpretation of long-term economic development different from those commonly found in the literature. It will be of interest to students and scholars of the economics of growth and change, as well as to economic historians and policy-makers. This book was first published in 1983.
