SQM director Louis Christopher responds in index debate

SQM director Louis Christopher has issued another salvo in the ongoing debate about Australian housing price indices. 

Christopher has tweeted a link to a 2005 Australian Financial Review article in response to economist Christopher Joye's article on Property Observer defending RP Data-Rismark's method of gathering house price data. 

RP Data-Rismark's home values index was launched in 2006, after the AFR article was written.
