| An integrated investigation of futures price, cash price, and government programs is presented in the context of an econometric model of acreage supply response for U.S. corn and soybeans. The analysis refines the role of different sources of price information in the farmers' acreage decision. It is found that the government corn support price program plays a major role in corn and soybean production decisions. Also, the results indicate that futures prices are not good proxies for expected future cash prices in the presence of government programs. This raises questions about the information efficiency of futures prices when government intervenes in the market place. |

| Previous attempts to measure agricultural decision makers' risk preferences have obtained values of the Arrow-Pratt coefficient in the range of approximately -.0002 to .0012. The recently developed interval approach for elicitation of risk preferences was used to estimate risk attitudes for Minnesota swine producers. Constant and decreasing absolute risk aversion were predominant among the sample. Seventy-eight percent of the respondents were in the Arrow-Pratt interval of -.0002 to .0003. A discriminant analysis using producer attributes and three estimated risk intervals concluded that 50 percent of the respondents could be classified in the correct risk interval. |

| The distribution of infauna across an estuarine mud flat, described by C. B. Rees in 1940, remains very similar more than 40 years later in spite of environmental changes that have occurred meanwhile. The apparent stability of the distribution and abundance of species is probably related to a constancy in the distribution of sediments on an eroding shoreline. Several species occur at greatest densities in restricted sections of the shore and lower densities elsewhere represent an outward spread of colonising individuals that do not survive to maturity. |

| 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. |
