Počátky zkoumání dlouhých vln[The beginnings of study of long waves]

The first modern long waves concepts can be found in the period of the fall of the 19th century and the beginning of the 20th century - the first notice describing their characteristics was done in 1847 in writings by H. Clarke. The majority of authors came to the long wave characteristics through the trials how to explain middle run cycles and economic crises. As the main stimulation leading to the development of the long run economic shifts research we can determine the moves of the price levels - the price long run statistics became the best indicators of economic activities at that time.Many authors were influenced by thoughts of K. Marx and F. Engels, who nevertheless never concerned on this problem as the main question of their interest. The beginning of forming the long wave theory is closely linked with the works of A.L.I. Helphand (Parvus) and particularly with the works of the Dutch pioneers - J.Van Gelderen and S.De Wolff. But the more developed evidence of existence and the effort to explain theoretically the phenomenon of the long waves are connected with N.D. Kondratieff. He became the real founder of the modern long wave concepts.
