TL;DR: In this paper, the authors presented results of spectral analysis that has detected the presence of Kondratieff waves (their period equals approximately 52-53 years) in the world GDP dynamics for the 1870-2007 period.

TL;DR: A database of historical and archaeological information from 30 regions around the world over the last 10,000 years revealed that characteristics, such as social scale, economy, features of governance, and information systems, show strong evolutionary relationships with each other and that complexity of a society across different world regions can be meaningfully measured using a single principal component of variation.

TL;DR: The relationships between K-waves and major technological breakthroughs in history are analyzed and forecasts about features of the sixth Kondratieff wave are offered and it is argued why the technological breakthrough will occur in health care sector and connected spheres.

TL;DR: In this article, an unusually clear K-wave pattern in the dynamics of the number of patents granted annually in the world per 1 million of the world population was revealed, which goes counter to the logic suggested by Kondratieff, Schumpeter and their followers who expected the increases in the invention activities during B-phase and their decreases during A-phase.

TL;DR: In this paper, the authors show that the patterns observed in pre-modern world population growth are not coincidental at all, and that the simplest regularities accounting for extremely high proportions of all the macrovariation can be found just for the largest possible social system.
