E. J. Nanson, Social Choice and Electoral Reform

The most distinctive Australian contribution to institutional design is the construction of electoral systems. This paper locates the work of E. J. Nanson 1850-1936; Professor of Mathematics, University of Melbourne, 1875-1922 in its intellectual context. After setting out the puzzle of the frequent discoveries and disappearances of axiomatic social choice, and its awkward relationship with electoral reform, the paper explores Nanson's arguments in both social choice and electoral reform. The first were good; the second disappointingly weak. Nanson's failure to influence Australian institutional design at the foundation of the Commonwealth and the subsequent adoption of Nanson's recommendations for Senate elections are analysed.
