Philanthrocapitalism, his previous book (also with Green) on the global revolution under way in philanthropy, has been described as "terrific" by the New York Times columnist Nicholas Kristof, and hailed by both former New York mayor Michael Bloomberg and President Bill Clinton. Matthew created the term 'philanthrocapitalism,' which refers to the forward-thinking practice of applying business methods and measures to philanthropy – in other words, harnessing the power of the economy to generate social change. Matthew is also the author of Essential Economics, the official Economist layperson's guide to economics.
Matthew is the author of several of The Economist's special report supplements, including most recently A Bigger World, which examines the opportunities and challenges of the rise of emerging economies and firms; The Business of Giving, which looks at the industrial revolution taking place in philanthropy; Kings of Capitalism, which anticipated and analyzed the recent boom in private equity; and Capitalism and its Troubles, an examination of the impact of problems such as the collapse of Enron. In 1994, he wrote an acclaimed special report on corporate governance, Watching the Boss.
