In the article on extensive statistical material over long periods of time shows the relationship of the magnetic radiation from the sun cycles and cycles of key macroeconomic indicators, namely, GDP, the level of stagflation (an index print) including seasonal cycles, the cycles Kuznets and Kondratieff cycles. The author explains this relationship on the basis of the results of scientific experiments conducted by the Institute of Space Research of the Russian Academy of Sciences. As a result of these experiments a negative effect of magnetic storms on the mental and physical well-being, which, as the author shows, leads to decrease in labor productivity and gross domestic product has been proved. Therefore, cyclic geomagnetic disturbances are the main cause of cyclicity of main economic indicators. Thus, it is possible to develop economic forecasts based on astrophysical predictions of solar activity and geomagnetic disturbances. The author has developed some of them. Identifying strong direct relationship of long waves of stagflation in the U.S. and long (large) cycles of solar activity, and the identification of a strong geomagnetic feedback seasonal and economic cycles in the U.S. economy, and Russia are considered to be the scientific innovation of the article.

Subject matter of the research is the economic cycles of the world, national, and regional economies. Purpose of the work is to show their close relationship with the cycles of solar activity. The author used the methods of correlation and graphical analysis. It relies on the objectivity of the methodology of industrial relations, namely, their dependence on the parameters of the magnetic field of the Earth. As a result, the article identified the following close relationship: 1. cycles of unemployment in the states of New York, Texas and California with the maxima and minima of solar activity; 2. changing the polarity of the magnetic fields of the sun and economic crises in the U.S.; 4. extrema of monthly Wolf numbers and cycles of world output; 5. long waves of the global product and solar activity. On this basis, the author made a forecast deterioration in the global conjuncture in 2014–2015 years. The results can be used in the predicting the dynamics of the world, national and regional economies.
