Kondratieff waves constitute a sort of mystery that has been haunting economic and social researchers for almost a century. Why do we observe such regularity in the long-term behavior of economic and non-economic indicators? Why in certain periods do we observe prolonged upswings, whereas in other periods – notwithstanding all the enormous efforts of interested macroeconomic actors – economic development is accompanied by prolonged depressions? What gets out of order in social and economic mechanisms? Since the seminal works published by Kondratieff, a number of outstanding researchers have made significant contributions to our understanding of the possible factors affecting and provoking long-term fluctuations of human economic affairs. On the other hand, it has become more and more clear that K-waves influence many social-related processes. However, nobody appears to have found yet an entirely satisfactory solution of ‘Kondratieff's mystery’, and it continues to attract researchers. That is why we have decided to try to unite the forces of such researchers around the new almanac. This first issue offers a wide panorama of views on the Kondratieff waves' phenomenon; here one can also find information on Kondratieff’s life and works. This edition will be useful for economists, social scientists, as well as for a wide circle of those interested in the problems of the past, present, and future of world economics and globalization.
