In this article, we consider the mainsprings of John Nevile’s many contributions to economics. John has repeatedly argued that because ‘economic actions, institutions and policies affect people’, they have an ethical dimension (Hawtrey and Nevile, 1986: 1), and he has stressed the importance of understanding the value judgements on which economics rests. His policy suggestions are aimed at improving social justice and the well-being of the most vulnerable. Apart from his deep knowledge of economic theory, his Christian faith provides an important foundation for his analysis, particularly of policy.
