For those after the full debate, see:
- McCloskey and Ziliak, "The Standard Error of Regressions," Journal of Economic Literature 1996.
- Ziliak and McCloskey, "Size Matters: The Standard Error of Regressions in the American Economic Review," Journal of Socio-Economics 2004.
- Hoover and Siegler, "Sound and Fury: McCloskey and Significance Testing in Economics," Journal of Economic Methodology, 2008.
- McCloskey and Ziliak, "Signifying Nothing: Reply to Hoover and Siegler."
McCloskey has been making this point for some time, and a longer list of papers is available here, including several shorter (yet unsurprisingly persuasive) pieces.
