In a recent trip to the center of the world, I found myself confronting the big development questions in a low-income country with reasonably propitious circumstances. Papua New Guinea (PNG) is larger, richer, and growing faster than I had thought. It will go to the polls this very month to elect a new government. It is also facing all the dilemmas faced by most low-income countries since the 1950s—political fragmentation, resource curses, income inequality, and poor health. Have we learned anything to help it meet those challenges?
