Domestic marketOwn price (η)Values of market elasticities used in the analysis are drawn from existing econometric research,economic theory and discussion with various industry participants. Typically, the own price demandelasticity for eggs applied to eggs purchased by consumers and in most studies no distinction is drawnbetween caged and alternative modes of production. We require own-price and cross-price demandelasticities for caged shell, processed and alternative shell eggs.A very useful source of information for elasticities is Baltzer (2003). He presents disaggregatedelasticity estimates of own price demand for eggs own and cross price (battery cage, barn eggs, freerangeeggs, organic eggs and pasteurised eggs). The own price (uncompensated) estimates rangebetween –1.69 to –2.71. These estimates are significantly higher (i.e., elastic) than previously410
