Estimating the effectiveness of extension information systems using farm trials and subjective probabilities

A method of combining survey data and Dairy Herd Improvement Association (DHIA) records to achieve low cost farm trials is presented. Farm trials and surveys of current practices and production responses are useful to identify yield gaps between expectations predicted from experimental findings and actual field results. Different management schemes can be ranked using subjective probabilities and stochastic dominance to enhance successful implementation of research findings and to increase the feedback between researchers, extension workers, and producers. A survey of current masitis control practices and expected milk yield response is the example. Combining survey results with DHIA records allowed estimating the relationship between somatic cell counts (SCC) and milk yield. Eliciting beliefs about the relationship between SCC and milk yield showed that producers agreed with predictions from the statistical model. Subjective probabilities about SCC and mastitis control practices showed that our sample of experts and producers consistently ranked the different practices but extension agents had no consensus about the the most or least effective ones.     

A comparison of several approximations to the power function of the likelihood ratio test in covariance structure analysis*

In this paper we compare alternative asymptotic approximations to the power of the likelihood ratio test used in covariance structure analysis for testing the fit of a model. Alternative expressions for the noncentrality parameter (ncp) lead to different approximations to the power function. It appears that for alternative covariance matrices close to the null hypothesis, the alternative ncp's lead to similar values, while for alternative covariance matrices far from H_o the different expressions for the ncp can conflict substantively. Monte Carlo evidence shows that the ncp proposed in Satorra and Saris (1985) gives the most accurate power approximations.     

Corporate Leverage and Nondebt Tax Shields: Evidence on Crowding-Out

A negative relationship between corporate leverage and tax shields has been predicted because a large nondebt tax shield reduces the expected value of interest tax savings and lessens the advantage of debt financing. Previous studies, however, have provided inconclusive and contradictory evidence on whether nondebt tax shields crowd-out debt financing. The analysis herein relies on unique constructs of discounted depreciation tax shields and presents evidence that crowding-out does not occur. Furthermore, it is shown that contradictory inferences may result from analysis of annual tax depreciation deductions instead of discounted tax shields. The findings suggest that firms with substantial cash flow from depreciation exploit their higher debt capacity by maintaining a capital structure with significantly more debt than otherwise.     

Professorial Rankings of Australian Accounting Departments

This article presents the results of a survey of professors in accounting departments in Australia. Professors ranked Australian accounting departments on a variety of research, teaching and staffing attributes, on contributions to the accounting profession and provided an overall ranking of the departments. Overall rankings placed the University of Queensland and the University of New South Wales a close first and second, followed by the University of Sydney, the University of Melbourne, the University of Western Australia, and Monash University. Analysis of the separate sub-dimensions of performance shows that it is variations in respondents' perceptions of research-related performance of departments which accounts for variation in the overall ranking. We also asked the professors for their views on several issues facing accounting educators and those who recruit accounting graduates. Most believed that there should be more breadth in undergraduate accounting courses than is currently the case. However, most felt that recruiters would prefer degree structures to remain as they are. There was overwhelming consensus that it was reasonable to expect ethics to be taught in accounting programs; that the Australian Securities Commission should not replace corporate management in the appointment of auditors; and that accounting standards should not be written to force very conservative depictions of profitability and financial position. There was disparity of opinions on whether auditors ought to be expected to foreshadow financial distress; whether the audit role should be expanded to explicitly embrace fraud detection; and whether financial reports should be understandable to the lay person.     

INDEPENDENT EXPERT'S REPORTS IN TAKEOVER BIDS

This paper reports an empirical examination of independent expert reports in takeover bids using the 170 reports that were issued in the 364 cash-based bids that occurred between January 1988 and December 1991. It was found that bid premia offered in takeover bids where an expert's report was issued were not significantly lower than bid premia in other bids. This may be attributable to independent experts acting as a countervailing influence on bidders holding a superior pre-bid bargaining position. Next, some dimensions of the “fair and reasonable” criterion that experts are required to use are examined. These are the single-test and dual-test interpretations of the phrase, the relation between offer price, market price and the expert's valuation of the target, the cost and length of expert's reports and, finally, the influence an expert has on the outcome of a bid.     

Production restructuring in the textiles and clothing industries

This article analyses the processes of restructuring in the textiles and clothing industries in a locality. Particular attention here is focused on new technology, labour flexibility, sub-contracting patterns and skill factors. The extent to which the process of restructuring involves a conscious and deliberate move to new patterns of work organization is considered.
