Notes
I thank Dennis Rose and Kerrin Vautier for reading an earlier version and for preventing me from making too many unwarranted assertions. Roger Rose rendered capable research assistance in preparing the statistical material. These people are not responsible, however, for any remaining undetected errors or misstated views. I am also grateful to personnel of the NZIER, the Department of Trade and Industry (including the Distribution Council) and the Department of Statistics for their help in providing access to the basic information sources on which the research section of this article is based.
