| Studies of the ease of substitution between inputs in production have generally been carried out within a production framework of an explicit functional form. In this study, a somewhat different approach is followed. A model of derived demand for primary factors of production, land, labour and capital is formulated to enable inferences to be made about the characteristics of the unspecified production function. The model is used to obtain estimates of the pairwise Allen-Uzawa substitution elasticities which are secondary parameters of the underlying production function. The reported FIML estimates from aggregate time series data for the period 1920/21 to 1969/70 indicate very low and marginally different substitution elasticities between different pairs of... |

| The rise in the domestic price of oil products implied by the new import parity pricing policy for domestic crude oil is likely to pose some problems for macroeconomic management. In this paper an attempt has been made to quantify the short-run adjustment problems involved, using the ORANI 78 model of the Australian economy. Results are presented for a range of variables of interest, including macroeconomic variables, industrial and workforce composition and farm incomes. With fixed real wages, farm incomes are projected to decline by between 6 and 8 per cent. |

| Larvae of the butterfly Erionota thrax, the banana skipper, destroy the leaves of bananas by eating them and forming massive protective rolls of leaf tissue. They were first observed in north-western Papua New Guinea in 1983 and over the next 6 years spread throughout the mainland at the rate of up to 500 km/year. E. thrax has also spread across the ocean to the east, to invade New Britain, Duke of York and New Ireland islands, and possibly Bougainville. As the banana skipper spread, it destroyed an average of some 60% of banana leaves, leading to both a serious delay in fruit maturation and reduced weight of banana bunches. Previous successful biological control of E. thrax when it invaded Mauritius, Hawaii, Guam and Saipan encouraged Papua New Guinea... |

| The results of the Henderson Poverty Inquiry's 1973 farm household income survey are discussed and supplemented by income distributions based on taxation returns from 1968/69 to 1972/73. It is concluded that much low income 'poverty' is temporary, being the product of the instability of agriculture. A case is made for the inclusion of wealth in farm and non-farm welfare comparisons. Proposals aimed at directly increasing incomes are discussed and hypothetical income distributions are presented to indicate the impact of the Henderson Inquiry's guaranteed income scheme on farm income distributions. |

| This paper examines the costs and benefits of producing biomass fuels from mallee eucalypts grown in low rainfall areas of Western Australia. The fuels examined are ethanol and renewable electricity. As a means of examining the competitiveness of these energy sources with conventional fossil fuels, we estimate the price gap between ethanol and petrol and the cost of producing a unit of electricity by conventional means versus biomass electricity. Both comparisons are made on an energy equivalent basis. The potential for future advances in processing technology is built into the analysis. We find that ethanol is not price competitive with petrol, even after considering environmental benefits associated with biomass fuels. This finding raises questions about... |
