| Conventional growth curves, such as the logistic and Gompertz, though both useful and successful as descriptive measures, lack economic substance. Where a new product is developed expressly to compete with an existing close substitute, any economist might reasonably expect the relative prices of the two goods to be relevant to the rate at which the innovation is adopted. Yet growth curves of the class mentioned above are functions of time only. In this paper we attempt to allow for the influence of price. The logistic law of growth remains basic to the pattern of adoption in our model. However, it is assumed that relative prices can both accelerate the rate of adoption, and affect the long-run share of the market enjoyed by the new product. (We shall use... |

| Production instability has been rightly regarded as one of the key problems of Australian agriculture. Campbell has emphasised that little attention has been focussed on reducing fluctuations in output as a means of cushioning income variations, although a great deal of interest has been taken in various measures designed to stabilize price. (l) An attempt is made in this paper to split up total variability of aggregate wool income into two components: the first corresponding to production uncertainty, and the second to price uncertainty. It is only by this sort of approach that we are in a position to gauge the possible effectiveness of any scheme designed to stabilize aggregate income, whether such a scheme act through price or output. This analysis... |

| An attempt is made to combine, empirically, the estimation of product transformation surfaces with the more conventional methods of linear supply analysis. This synthetic approach is used to fit simultaneously a system of six aggregate supply functions. The products covered account for more than 70 per cent of the gross value of Australian rural production. |

| As a guide to the reorganisation of resources, the MVP /MFC comparison can result in the adjustment of resources to new levels which are actually further away from their optimal levels than their original values. Duloy illustrated this paradox mathematically in the context of fitted agricultural production functions in a paper published in 1959. His result is of considerable importance to agricultural micro-economists; however, it is not easy to teach to students of poor mathematical background. The need to be able to teach in literary form the Duloy Paradox--that increasing the application of a factor with a relatively high MVP can result in a movement away from the optimum input-mix--led to the following analysis. |
