There’s a gaping hole in the global education budget and it’s 200 billion US dollars deep. Yearly. Part of the problem has to do with taxes: Many developing countries raise less than 20% of their GDP in tax revenues and out of this, education should take up between 4 to 6% of GDP. That’s a tall order in deficitary times. Michael Ward, OECD Senior Analyst specialising in global educational development issues and Bert Brys, Senior Tax Economist at the OECD, walk us through efficient education spending and how to raise money for education through better taxing.
