| A theoretical optimal hedging model is developed to determine potential demand from Australian farmers for a hedging tool to remove the economic consequences of climate related variability in wheat yield. In the past, financial instruments have been developed to hedge price risk on capital markets; however, in more recent times new financial instruments, weather derivatives, have been developing that hedge the volumetric risk associated with unfavourable weather. Weather derivatives have the ability to effectively hedge weather related volume risk for the agricultural, mining, energy and manufacturing industries, while also providing a risk management tool for construction firms and special events organisers, although there are still many hurdles to... |

| It has been established that the absence of risk markets justifies market intervention in principle. The form of intervention that has been discussed most widely in the literature is the buffer stock. This paper points out that other forms of intervention, specifically buffer funds, are likely to perform better. The analysis shows that buffer funds are likely to outperform buffer stocks because they address market failure more directly. A sub-theme developed in this paper is that since buffer funds are enforced saving, it follows that policies that address capital market failure are likely to dominate buffer funds and buffer stocks in welfare terms. |

| Klieve and MacAulay (1993) (KM) analyse bargaining between the Australian and Japanese Southern Bluefin Tuna (SBT) industries using game theory. The KM model is a Nash equilibrium with symmetrical information, threat functions and a set of biological constraints. When we attempted to include the New Zealand SBT industry as a player in the KM model, we discovered important shortcomings in it. In this comment, we outline three major shortcomings in the KM model and propose an alternative model of a Nash equilibrium for the SBT industry. |

| The study uses empirical measures of market concentration to examine buyer competition in wool between 1974 and 1992. Three measures of concentration are examined, concentration ratios, Herfindahl indices and Lorenz curves. Data from the Australian Council of Wool Exporters are used to obtain estimates of these measures over the sample period. The results indicate that the buying sector in the Australian wool market is relatively concentrated and calculation of Spearman correlation coefficients indicate that rankings have not altered significantly in recent years. |

| Some key elements in drought relief policy are outlined and the major themes in associated lobbying are discussed. Recent policy changes announced in 1992 are described in detail against the background of the Report of the Drought Policy Review Task Force (1990). Indifference curve analysis is used to compare recent developments with the preceding policies and the targeting problems associated with both policy regimes are discussed. It is found that the new drought relief policy is unsatisfactory in a number of ways. Discussion of the welfare implications of recent changes in drought policy is then provided and conclusions are finally drawn. |

| In this paper, some aspects of the application of optimal-control techniques to wool industry price stabilisation are considered. It is not intended to provide a blueprint for the immediate adoption of optimal-control techniques in the management of wool price stablisation. Rather, the contribution is to the developmental and evaluative process involved in considering these techniques. A new econometric model of wool price and supply is also presented, since none of the existing models satisfied the requirements of the study. |

| The nuclear accident at the Chernobyl plant in 1986 is described and a summary of its immediate effects on people and the environment outlined. Then there is a summary of the important parts of the literature on diseases and deaths resulting from radiation and mortalities to date and the way mortality data became increasingly conservative over the years is discussed. Today, there is still uncertainty about future mortalities dues to long latency periods for many cancers however cancer deaths in Chernobyl affected regions are expected to be similar to non-Chernobyl controls. The major literature on environmental effects on wild species, forests, water and agricultural land are then reported with a brief discussion of remediation work and of current trends.... |

| From my experience as a manager of economic research I believe that tertiary agricultural economics education has two major shortcomings. First, a large proportion of new graduates have poor writing skills. Their problems in this area revolve around ignorance of elementary grammar and lack of precision in written expression. The second problem that I perceive is that a significant proportion of economics graduates appear to lack any knowledge of economics. These individuals should have been failed from programs yet somehow have managed to get degrees. |

| The potential for hedging Australian wheat with the new Sydney Futures Exchange wheat contract is examined using a theoretical hedging model parametised from previous studies. The optimal hedging ratio for an `average' wheat farmer was found to be zero under reasonable assumptions about transaction costs and based on previously published measures of risk aversion. The estimated optimal hedging ratios were found by simulation to be quite sensitive to assumptions about the degree of risk aversion. If farmers are significantly more risk averse than is currently believed, then there is likely to be an active interest in the new futures market. |

| The importance of welfare losses resulting from discrepancies between Australian Wool Corporation and trade valuations of different grades of wool is discussed. Cross-sectional data are used to relate variations in wool attributes to variations in price during 1976-7 and a model is derived for determining grade prices that are consistent with market valuations of different grades. The spatial consistency of the model is tested using data from eleven time periods and from two geographically isolated markets. Comparisons between trade valuations and the grade price differentials used in the Minimum Reserve Price Scheme by the Australian Wool Corporation are made. |
