The asymmetric path of economic long waves

The purpose of this paper is to analyze the pattern and behavior of Economic Long Waves over time, using the long-wave chronologies of two driving economies, the USA and the UK. The statistical evidence seems in general to support the hypothesis that Long Waves are not symmetric and their regularity is based on longer periods of upwave than downwave (contraction-skewed), which implies a negative asymmetric path of these waves over time.
