Abstract
Large-scale industry investment in quality assurance and marketing campaigns for Australian lamb make both Meat Standards Australia (MSA) sheep meat and lamb advertising campaigns modern and plausible determinants of Australian consumer demand for lamb. Incorporating non-discretionary demand shift variables such as these into the General Almost Ideal Demand System (GAIDS) model may provide a suitable method to test for their impact on Australian lamb consumption patterns. This paper extends on a recent application of the GAIDS to Australian meat data by incorporating two alternative and novel methods of demand-shift index construction. It also proposes a semi-formalised approach to GAIDS model development and specification when dealing with underlying data quality issues.
