Lakatos (on Duhem-Quine thesis): 'no experimental result can kill a theory: any theory can be saved from counter-instances either by some auxiliary hypothesis or by a suitable reinterpretation of its terms'. And, because econometrics is non-experimental, the scope for such theory-rescue is widened considerably. regards, Tom Walker http://www.vcn.bc.ca/timework/covenant.htm
