David Courtney Boyle, 1958-, is a British author and journalist who writes mainly about history and new ideas in economics, money, business and culture. He lives in the South Downs. His most recent public role was conducting an independent review for the Treasury and the Cabinet Office on Barriers to Public Service Choice, which reported early in 2013. His book Authenticity put the phenomenon on the business and political agenda. His previous books The Tyranny of Numbers and The Sum of Our Discontent predicted and fermented the backlash against target culture. Funny Money helped launched the time banks movement in the UK. More recently, he has been writing about why organisations and public services are so ineffective, working with the New Economics Foundation and NESTA on a series of publications about coproduction, and publishing his own solutions as The Human Element. This argues that organisations have abandoned human skills in favour of numerical targets or IT systems, which frustrate the business of building relationships and making things happen. His 2020 book Tickbox has been well reviewed. His history books usually have a business or economic dimension, including Blondel's Song (UK) and The Troubadour's Song (USA) about the imprisonment and ransom of Richard the Lionheart. His 2008 book Toward the Setting Sun tells the intertwined story of Christopher Columbus, John Cabot and Amerigo Vespucci and their race for America in the 1490s. His 2010 book, Eminent Corporations with (Andrew Simms) has introduced a new genre, the mini-corporate biography, launching the idea of corporate history as tragedy. His recent book Broke has launched a public debate about the plight of the middle classes. He has been the editor of several journals including New Economics and Town & Country Planning. He is a fellow of the New Economics Foundation and has been at the heart of the effort to develop co-production and introduce time banks to Britain as a critical element of public service reform. He has been closely involved in their Clone Town Britain campaign and writes about the future of volunteering, cities and business. He edited the Foundation's publications New Economics, News from the New Economy, and then Radical Economics from 1987-2010. David helped found the London Time Bank, and was co-founder of Time Banking UK. He has been a candidate for Parliament of the United Kingdom. He was editor of the weekly Liberal Democrat News from 1992-1998. His bestselling books for Kindle have mainly been about history, including Alan Turing: Unlocking the Enigma, Peace on Earth and Unheard, Unseen.
