It is widely believed that small and medium enterprises (SMEs) are very important for economic growth. According to the World Bank, such enterprises contribute up to 45% of total employment and up to 33% of GDP in developing countries. Since the SMEs account for more than 90% of total enterprises in the world, the intense competition among them leads to an increase in their Research and Development Expenditures (R&D), thus decreasing unemployment and promoting economic growth.
