Tech giants entering the banking and financial industry is not an issue of the future, it is already happening. This phenomenon has crucial implications that extend well beyond the banking system. There are questions like: Will tech giants be competitors of incumbents or will they rather partner up? How is the financial regulation going to handle this radical change, and will it succeed in creating a level playing field? What are the implications from a political and social point of view? Will tech giants acquire too much bargaining power in dealing with sovereign states, allowing them to shift political decisions and laws in their favour? This edited book provides a number of answers to these questions through a research effort on the economic and political implications of this technological revolution. While it is impossible to stop this revolution, it poses the challenge of steering towards a sustainable and inclusive improvement of our society and economy.
