123-630: A coalition of 50 charities and other NGOs began advocating for what they labelled a Robin Hood tax , which would tax transactions of stocks, bonds and other financial securities. In 2011, the European Union (EU) proposed an EU-wide FTT; consensus, however, could not be reached among all EU countries. In 2013, 11 countries in the EU's Eurozone established the European Union financial transaction tax , estimated to generate €35 billion per year. In 2012,
164-547: A group of UN experts recommended that the United Nations adopt a FTT, estimating that the tax could bring $ 48-$ 250 billion in revenue, to be channelled to "fighting poverty, reversing growing inequality, and compensating those whose lives have been devastated by the enduring global economic crisis". In the UK, bank taxes have been proposed as another means of worldwide taxation, as have been sales taxes . Proposals to combat
205-724: A major corporate tax haven , is still materially underestimated by Orbis–database studies due to technical factors (even though these studies rank Ireland as the 5th largest global corporate Conduit OFC ). Research published by Zucman, Tørsløv and Wier in June 2018, showed that Ireland is the largest corporate tax haven in the world, even larger than the entire Caribbean corporate tax haven system. This research also showed that tax disputes between high–tax jurisdictions and corporate tax havens are extremely rare, and that tax disputes really only occur between high–tax jurisdictions. Along with James R. Hines Jr. and Dhammika Dharmapala , Gabriel Zucman

287-420: Is Back , Zucman and French economist Thomas Piketty investigate the evolution of aggregate wealth–to–income ratios in the top eight developed economies, reaching back as far as 1700 in the case of the U.S., U.K., Germany, and France, and find that wealth–income ratios have risen from about 200–300% in 1970 to 400–600% in 2010, levels unknown since the 18th and 19th centuries. Most of the change can be explained by
328-500: Is a hypothetical system for the collection of taxes by a central international revenue service . The idea has garnered currency as a means of eliminating tax avoidance and tax competition ; it has also aroused the ire of nationalists as an infringement upon national sovereignty. Discussion of a global financial transaction tax (FTT) increased in the 2000s, especially after the late-2000s recession , and especially in Europe. In 2010,

533-544: The "traumatic political event of my youth", as being when Jean-Marie Le Pen reached the final rounds of the 2002 French presidential election , when Zucman was 15. In 2018, Zucman said of that event: "A lot of my political thinking since then has been focused on how we can avoid this disaster from happening again. So far, we’ve failed". From 2005 to 2010, Zucman attended the École normale supérieure de Cachan , one of France's prestigious Grandes Écoles . Hereafter, he first earned his M.Sc. in economic policy analysis in 2008 and
574-595: The 2014 success of French economist Thomas Piketty 's bestseller Capital in the Twenty-First Century . In the book, Piketty proposes that because the rate of return on capital tends to exceed total growth, inequality will tend to rise forever without government intervention. The solution he proposed is a global tax on capital. He imagined that the tax would be zero for those with less than 1 million euros, 2% for those with more than 5 million, and 5-10% for those with more than 1 billion euros. Piketty suggested

(According to Cliff Kincaid , Castro advocated it "specifically in order to generate U.S. financial reparations to the rest of the world," however a closer reading of Castro's speech shows that he never did mention "the rest of the world" as being recipients of revenue.) Castro cited Holocaust reparations as a previously established precedent for
861-519: The World Shipping Council. The International Maritime Organization reached agreement in 2022 that a global carbon tax for shipping should be established. However, there is wide disagreement about the price level, with proposals ranging from $ 150 to just $ 2 per tonne of fuel. In 2023, research from CE Delft found that global shipping emissions could be cut by between a third to a half by 2030 without harming international trade. This

Based on his calculations, he finds about 8% of the global financial wealth of households, or $ 7.6 trillion, to be held in tax havens, three–quarters of which go undeclared. In 2017–18, Zucman focused on the scale of multinational tax avoidance by base erosion and profit shifting ("BEPS") tools in the largest corporate tax havens . Zucman believes Ireland, recognised as
943-579: The concept of reparations . Castro also suggested that the United Nations be the administrator of this tax, stating the following: "May the tax suggested by Nobel Prize Laureate James Tobin be imposed in a reasonable and effective way on the current speculative operations accounting for trillions of US dollars every 24 hours, then the United Nations , which cannot go on depending on meager, inadequate, and belated donations and charities, will have one trillion US dollars annually to save and develop

It has been estimated that for the US, a tax of 2% on fortunes greater than US$ 4 million would generate US$ 500 billion per year. About half of that amount, about 300 billion per year, corresponds to the total developmental budget goal of 0.7% GNP of industrialised countries (see Millennium Development Goals ), which would enable poorer countries to cross

Consequently, some national emissions trading schemes are theoretically compatible with those of other nations whose schemes have similar standards. In 2017, the EU agreed to link
1681-557: Was suggested that a uniform global carbon tax could eliminate the need for carbon border tariffs. Some research has suggested that such a proposal could be popular if the revenue generated by the tax is paid directly to citizens, a payment known as a carbon dividend . By 2021, global industry-wide carbon taxes were supported by groups representing 90% of the shipping industry, including the International Chamber of Shipping , Bimco, Cruise Lines International Association and
