. "The situation in Azerbaijan, where more than 90% of export during the first quarter of 2001, was due to oil and oil products, can be named dangerous", Dmitri Sorokin, the head of the center of political-economic studies of Russia, Doctor of Economy Sciences, thinks. It was informed by the Caspian information agency. According to the scientist, " oil is not a reliable source of income as its price constantly changes". The danger of depending on a "monoproduct" the economist confirmed with the example of Cuba, where 95% of currency income is due to sugar. The minimal fluctuation of the price of that product "shakes" the economy of the country.
