Economic Growth and Cycles in European Union, Usa and Japan 1900-1999. A general view and analysis of causal relations.

The analyses of economic cycles in OECD countries during the last century, show there is a lower intensity of fluctuations in the second half than in the first. Conversely, the second half has had a greater intensity of economic growth, as a consequence of several factors such as peace, good economic policy for industrialised countries, the development of science and technology and the increase in the educational levels of populations and labour force in many countries of the European Union, the USA, Japan and other countries.
