A couple of months ago, a paper I worked on with co-authors from the Wittgenstein Centre was published in the Proceedings for the National Academy of Science of the United States of America. The significance blurb and abstract are below.
Abel, G.J., Bakarat, B., K.C., S. and Lutz, W. (2016). Meeting the Sustainable Development Goals leads to lower world population growth. Proceedings of the National Academy of Sciences. 113 (50) 14294–14299
