| The comparative productivity of inputs is often the focus of applied studies of production. For example, one might wish to compare the marginal product of water in irrigation districts to provide guidelines for capital investment in new water projects or to assist in water allocation decisions. The purpose of this note is to illustrate a straightforward econometric method for making such comparisons. It is assumed that panel data are available for T periods on N cross-sectional units and that output is produced according to a stochastic Cobb-Douglas production function. The Cobb-Douglas function was chosen because it has a simple formula for the marginal product and has been found to perform well in studies of agricultural production. The statistical... |

| Pollution of the River Murray by salt imposes costs on domestic and industrial users in Adelaide and to irrigators on the River Murray. Salt enters the Murray-Darling system through saline ground water aquifers and from irrigation and drainage of saline land. Irrigation and drainage generate benefits from improved agricultural productivity and impose costs through increased salt loads to the Murray-Darling system. The salinity of the River Murray can be reduced by pumping highly saline ground water into evaporation basins before it enters the River Murray. This paper presents a mixed integer linear programming model which is used to determine the mix of ground water interception schemes and land improvement schemes that minimises the net present value... |

| A small stratified sample was drawn from irrigated dairy farms judged to exhibit two degrees (high and low) of salting in the soil. Cobb-Douglas production functions were fitted to time series and cross sectional data for each stratum. The results support the conclusion that the data from the two strata can be pooled and that the quality of the soil in this area can be modelled using an analysis of covariance approach. A preliminary confidence interval for the geometric mean of the ratio of the shadow price of water to the price of butterfat for farms in the sample was also calculated. This interval supports the hypothesis that rationed irrigation water is worth more to these farms than the price paid. |

| Dynamic programming is used to examine whether Australia should store wheat for subsequent sale at higher prices. The dynamic programming model is developed assuming that the demand for Australian wheat is perfectly elastic at the world price. An important consequence of this assumption is that the algorithm used in computing the optimal policy takes a very simple form. It is concluded that interest rate and wheat price in the following season are the major determinants of storage policy. When prices are stable, rule-of-thumb policies, such as storing when prices are below average, are sub-optimal. |

| Irrigators in Victoria have a water entitlement which is composed of a highly secure water right and additional water which may be purchased if available. Water entitlements in NSW are based on the irrigated area with the actual volume of water received in any year depending almost entirely on seasonal conditions. Musgrave and Lesueur (1973) argued that these entitlements could be replaced by a portfolio of entitlements, with each type of entitlement in the portfolio guaranteeing a nominated minimum value of water at a different probability. Thus, irrigators could purchase a portfolio of water entitlements which would suit their individual risk preferences. The purpose in this paper is to show how a water authority can construct a portfolio of water... |
