The Debate on Value Creation and Digitalized Companies
The growth of companies that provide digital services (such as search engines, online The growth of companies that provide digital services (such as search engines, online

above, the traditional international norm is that the first right to taxation of profits belongs to the above, the traditional international norm is that the first right to taxation of profits belongs to the
