| Existing econometric models for Australian broadacre agricultural production are few and have become dated. This paper estimates a multi-product restricted cost function using a unique quasi-micro farm level dataset from the Australian Agricultural and Grazing Industries Survey. Both the transcendental logarithmic and normalized quadratic functional forms are employed. Heteroskedasticity caused by the particular nature of the quasi-micro data is also assessed and accommodated. Allen partial elasticities of input substitution and own-and cross-price input demand elasticities are computed. The estimated demands for most production factors are inelastic to prices. Hired labour is responsive to own price and cropping input prices. |

| The estimation of large demand systems to investigate the patterns of consumption of households is notoriously difficult. This study develops a modified Almost Ideal Demand System model based on a flexible two-stage budgeting demand modelling framework to examine the effect of estimation procedures (Bottom-up and Top-down) on South African household food consumption parameters. Household food consumption was divided into seven broad food groups: meat and fish; grains; dairy products; fruits; vegetables; other foods. The demand systems were estimated using data from the 1993 South Africa Integrated Household Survey (SIHS) conducted by the South African Labour and Development Research Unit (SALDRU). Empirical results indicate that the Top-down approach is... |
