New Findings in Long-Wave Research [PDF ebook] 

This book presents new methods for the analysis of time series and the identification of long waves. In Part One it is shown that new time series analyses confirm the existence of Kondratieff long waves in economic growth for the 19th and 20th centuries. Part Two presents evidence on long waves in aggregate profit rates for selected major industrialized countries. Part Three covers theoretical discussions and attempts at modeling social, economic and technological factors in long waves.
