Solutions for the World’s Biggest Problems The world has many pressing problems. Thanks to the efforts of governments, NGOs, and individual activists there is no shortage of ideas for resolving them. However, even if all governments were willing to spend more money on solving the problems, we cannot do it all at once. We have to prioritize; and in order to do this we need a better sense of the costs and benefits of each “solution.” Solutions for the Worlds Biggest Problems offers a rigorous overview of twenty-three of the worlds biggest problems relating to the environment, governance, economics, and health and population. Leading economists provide a short survey of the state-of-the-art analysis and sketch out some promising policy solutions for which they provide cost–benefit ratios. The book is aimed not just at policy makers, but also at the many thousands of concerned citizens who want to see progress in the fight against poverty, disease, armed conflict and environmental degradation. Finding the best solutions requires as wide and as informed a debate as possible. To this end, a unique feature of the book is the provision of freely downloadable software which allows individual readers to make their own prioritizations of their preferred options for spending money to make the world a better place.
