"'Tax' is a bad word for politicians."
"You do need more revenues, and you do need to cut expenses. But you also don't want to go in a direction whereby increasing taxes creates a reticence to create new jobs. You don't want to increase taxes on work. You don't want to increase taxes on investment and the creation of wealth."
"Most businesses do not take governments seriously when it comes to climate, primarily because many governments have inconsistent and incoherent policies and then often keep changing them, sometimes retroactively. This makes businesses reluctant to invest in greener technologies."
"Our leaders must get to grips with the huge risk that carbon dioxide emissions pose to the economy and the environment. As we know, carbon dioxide is a long-lived gas. It hangs around."
"Ending our reliance on fossil fuels was never going to be easy."
"I feel confident that leaders will rise to this challenge with a stronger commitment to tackle climate change and seize the economic opportunities that a post-carbon world has to offer."
"Principles of fair and equitable treatment included in many treaties are uncontroversial as general principles of good public governance."
"Governments can and do expropriate investors or discriminate against them. Domestic judicial and administrative systems provide investors with one option for protecting themselves."
"Providing investors with recourse against governments is valuable."
"The concept of national treatment is a core component of investment and trade agreements. It promotes valuable competition on a level playing field. Investment treaties should not turn this idea on its head, giving privileges to foreign companies that are not available to domestic companies."
"Some politicians fear the burden that migrants will impose on local communities and taxpayers. Others fear extremists masquerading as genuine refugees."
"European leaders cannot afford to be afraid. The refugee crisis is not one from which they can opt out. No magic wand will empower leaders to transport more than a million people back across the Aegean and the Bosphorus to Mosul and Aleppo, or across the Mediterranean to Eritrea, Somalia, and Sudan."
"Some refugees will find it relatively easy to find jobs. A university-educated Syrian civil engineer arriving in Munich will need to learn some German, but once this is done, he or she is unlikely to have to wait too long before employers come knocking."
"Our work at the OECD shows that migration, if well managed, can spur growth and innovation. Unfortunately, in the past, migration has not always been well managed: migrants have been concentrated in ghetto-like conditions, with few public services or employment prospects."
"In a globally interdependent world, a better financial and investment system cannot be achieved on a country-by-country basis. There may be no one-size-fits-all model for economic development, but without global standards and complementary regulations, the long-term outlook for the world economy will remain bleak."
"Regulations for international accounting and funding will have to be examined to identify policies that inadvertently discourage institutional investors from putting their resources into longer-term, illiquid assets."
"In order to encourage private investors to pursue long-term, responsible projects, governments need to promote consistent policies and frameworks."
"Unlike other essential goods, like clothing, shelter, or food, we take cheap or even free water for granted. It often takes a crisis, such as a major drought or flood, to spur investment and policy reforms in improving water security."
"Water security is not just for domestic policies. International co-operation is crucial to sustainably manage trans-boundary water bodies and river basins."
"History is full of lessons for how water crises could have been avoided or better managed."
"The OECD advocates a risk-based approach to water security and is calling on governments to speed up their efforts to improve efficiency and effectiveness of water management. We recommend improving water pricing to recover costs and to reflect the value of water to users and society."
"To give students the best possible chance to succeed, education must prepare them to handle issues that transcend national boundaries."
"By assessing the capabilities and knowledge of students in the highest-performing and most rapidly improving education systems, the OECD's Program for International Student Assessment provides valuable options for reform and information on how to achieve it."
"Countries like Japan do not have to change their cultures to address their educational shortcomings; they simply have to adjust their policies and practices."
"Creating a global platform for collaboration in education research and innovation has been the PISA initiative's aspiration from its conception in the late 1990s."
