Mapping the history of public economics in the twentieth century: an introduction to the special issue.

The papers in this issue deal with the transformation from public finance to public economics at a theoretical and philosophical level in the mid-twentieth century. Our introduction situates these papers within their intellectual context. To do so, we provide a broad outline of the trajectory of the field beginning with the transformation of welfare economics. Acknowledging the structuring role of Richard Musgrave and James Buchanan for the field, the papers highlight the key role also played by Paul Samuelson in the transition to public economics. Moreover, they underscore how ethical issues were formalised into normative economics at this critical juncture. [ABSTRACT FROM AUTHOR]
