The role of extension in the development of the farmer as entrepreneur

Different viewpoints were expressed at the 1990 annual national conference of the South African Society for Agricultural Extension regarding the role of extension in the development of the farmer as entrepreneur. It is expected that public funding will increasingly be limited to functions of general public interest. To achieve independence farmers should be willing to expose themselves to entrepreneur development stimuli. it is in the public interest to develop scarce human, economic and natural resources. Research findings indicate distinct behavioral differences between entrepreneurs of differing perceptions. A comprehensive interdisciplinary education is recommended for agriculturalists. Because needs change, education programmes must be re‐evaluated from time to time. It serves little purpose to educate people in extension who do not have a technical message to communicate. The state extension service seeks closer cooperation and liaison with agricultural co‐operative and private sector know‐how. Departmental policy will probably be less rigid in future.

A clear distinction should be made between information and extension services. The adoption of an ethical code for extensionists may be opportune. Relevancy is an important contributing factor to extensionist credibility.     

Marginal distributions of sequential and generalized order statistics

Expressions for marginal distribution functions of sequential order statistics and generalized order statistics are presented without any restrictions imposed on the model parameters. The results are related to the relevation transform, to the distribution of the product of Beta distributed random variables, and to Meijers G-functions. Some selected applications in the areas of moments, conditional distributions, recurrence relations, and reliability properties are shown. Key words:Order statistics; Generalized order statistics; Sequential order statistics; Record values; Distribution theory; Meijers G-function; Recurrence relations; Reliability properties.     

Reduced Form Auctions Revisited

This note uses the Theorem of the Alternative to prove new results on the implementability of general, asymmetric auctions, and to provide simpler proofs of known results for symmetric auctions. The tradeoff is that type spaces are taken to be finite.     

The ARCO decision: Inroads into the per se rule under Section 1 of the Sherman Act

In this study, the author analyzes the 1990 U.S. Supreme Court decision inAtlantic Richfield Company vs. USA Petroleum Company approving Atlantic Richfield’s maximum pricing plan improsed on its distributors (despite the Court’s recognition that theper se rule forbade such schemes). Theper se rule had been one of the last substantial measures of effective antitrust policy administered by enforcement authorities and the courts, perhaps even more fundamental than scrutiny of proposed mergers and predatory practices. That principle has been weakened by the ARCO decision. The author addresses some of the likely consequences of the ascendancy of the Chicago School and the NeoClassical theory generally in antitrust interpretation.     

Optimal fiscal zoning when the local government is a discriminating monopolist

Monopoly zoning by local governments has been studied extensively since the original article by White [1975, in: E. Mills and W. Oates, eds., Fiscal zoning and land use controls (Lexington Books, Lexington, MA)]. However, little or no attention has been paid to the possibility of monopolistic discrimination under such a regime. The question is: When will zoning multiple lot sizes be feasible given that buyers with different valuations of land cannot be coerced into purchasing particular lots? The literature on imperfect price discrimination by monopolists is brought to bear on this question. It is shown that the resulting zoning strategy may or may not involve multiple lot sizes. The factors determining the optimal strategy are studied in detail, with particular emphasis on the nature of the market for undeveloped land in the community.
