Over the past few decades, the concentration of wealth and property in the hands of a few has been facilitated by tax evasion, tax avoidance, and above all by tax competition. Fortunately, a determined move toward international cooperation among tax authorities is gathering its forces to do battle. This invaluable book shows how the globalization of trade, the digitization of the economy, tax competition between sovereign states, the erosion of the tax base, and the transfer of pro ts have all revealed the weaknesses of a traditional tax system that has reached its limits, and how numerous states and groups of states have joined efforts in creating a new international tax system designed to restore fairness and stability in the levying of taxes worldwide. Stemming from a 2016 conference initiated by the Canadian non-pro t organization TaxCOOP, convened by the World Bank and bringing together well-known taxation experts from prominent international organizations, the book presents outstanding contributions highlighting the impacts of tax competition and viable solutions. Among the issues and topics covered are the following: – electronic commerce and electronic money; – transfer pricing; – derivatives and hedge funds; – protecting tax whistle-blowers; – offshore tax investigations; – possibility of an international tax court; – impact of tax competition on developing countries; – carbon pricing; – tobacco taxation; and – effective taxation of the ultra-wealthy and their nancial capital. The chapters include details of country experiences and results, in some cases analyzed by key protagonists themselves. Collectively, the contributions take a giant step toward reinforcing the power of sovereign states in sectors such as the environment, education, and health. As an authoritative guide to increasing the level of transparency and accountability of private and public economic actors and restoring citizens’ trust in the fairness of our global governance systems, this peerless volume will be warmly welcomed by tax lawyers, taxation authorities, and interested academics worldwide.
