Helping Professionals in Business Behave Ethically: Why Business Cannot Abdicate Its Responsibility to the Profession

This paper compares the findings of studies of seven groups of professionals in various key segments of the fields of accounting and insurance conducted during 1990 through 1994 in an effort to determine the extent to which they tend to rely on various factors in their business and professional environments for help in behaving ethically in the course of their work. Commonalities among the findings for these rather diverse groups are highlighted and their possible implications for business and the professions are discussed.     

PROFITABILITY OF INCREMENTAL EXPENDITURE ON FIBRE PROMOTION

In this paper the impact of changes in wool promotion expenditure and changes in expenditure on the promotion of competing fibres are examined using an equilibrium displacement model. The emphasis is on examining impacts on producer profits net of promotion expenditure and on benefit-cost ratios measuring changes in producer surplus relative to changes in promotion expenditure. It was found, for example, that incremental expenditure on apparel wool promotion on the domestic market is unprofitable but incremental expenditure on promotion of apparel wool on the export market is generally profitable. Further, it was found that increased promotion of cotton and man-made fibres on the export market, with promotion of apparel wool unchanged, would reduce profits to apparel wool producers. Finally, a case is made for improved data availability in order to allow more comprehensive ex-ante and ex-post evaluations of promotion programs, thereby increasing the intensity of scrutiny of promotion programs to a level more in line with that for investment in rural research and development.     

COMPARATIVE FORECAST ACCURACY IN THE NEW SOUTH WALES PRIME LAMB MARKET

The market for Australian prime lamb is characterised by high production seasonality and a highly competitive retail demand. Because these factors often translate into substantial market variability, regular forecasts of supply and demand are important requirements of lamb market participants. There has been some forecasting activity in the state and national lamb markets but it has been a somewhat controversial activity. This paper assesses the comparative forecast accuracy of a range of methods in the New South Wales lamb market. The results indicate that no single method is clearly superior in all situations and the greatest scope for improving forecast accuracy in the New South Wales lamb market is through the use of combined econometric and naive approaches.     

Global virtual teams: a human resource capital architecture

As organizations continue to globalize their operations, it will become evident that most organizations do not have the resources to ‘fully man’ operations throughout the world. Therefore, management will be examining organizational options that reduce the demand on an already depleted pool of global managers. One of the options being examined by companies is the global virtual team (GVT). These complex teams are being considered as a bridge mechanism to allow multinational organizations to expand rapidly without taxing present global managerial skills. This paper uses a theoretical foundation based upon competency theory as the motivation for the formation of GVTs and to explain how they function. Four critical capitals (i.e. human, social, political and cross-cultural) are deemed to be essential for effectiveness of GVT and are discussed in the paper. In addition, a process for assessing the stock of capital in a GVT team is also developed in the paper.     

A Multinational Comparison of Key Ethical Issues, Helps and Challenges in the Purchasing and Supply Management Profession: The Key Implciations for Business and the Professions

This paper presents the findings of a study of purchasing and supply management professionals in India conducted to identify the key ethical issues they face in carrying out their work related responsibilities as well as to determine the extent to which various factors appear to be helpful or to present challenges to their efforts to act ethically in the course of their work. The Indian findings are then compared to those for studies conducted among purchasing and supply management professionals in the United States, United Kingdom and Canada. Key findings for the four studies are summarized and implications for business and the professions are presented.     

The non-monotonicity of the bias and mean squared error of the two stage least squares estimators of exogenous variable coefficients

Owen (1976) [Owen, A.D., 1976. A proof that both the bias and mean squared error of the two stage least squares estimator are monotonically non-increasing functions of sample size. Econometrica 44, 409–411.] has shown that in a two equation static simultaneous equation model both the bias and mean squared error of the two stage least squares estimator of the endogenous variable coefficient are monotonically non-increasing functions of the sample size. This paper shows that neither property carries over to the exogenous variable coefficient estimator.     

Governance,ownership structure,and performance of IPO firms: the impact of different types of private equity investors and institutional environments

This paper examines performance effects of ownership concentration and two types of private equity investors (venture capitalists and business angels) in firms that have recently undergone an initial public offering (IPO) in the United Kingdom and France. We expand and contextualize nascent understanding of multiple agency theory by examining heterogeneity of private equity investors and by suggesting that multiple agency relationships are affected by different institutional contexts. We employ a unique, hand‐collected dataset of 224 matched IPOs (112 in each country). Controlling for the endogeneity of private equity investors' retained share ownership, we find support for the agency theory argument that concentrated ownership improves IPOs' performance. The research also shows that the two types of private equity investors have a differential impact on performance, and the legal institutions in a given country moderate this impact.

Integrating crop modelling and production economics to investigate multiple nutrient deficiencies and yield gaps

A method is described for integrating crop modelling and production economics to quantify optimum applications of multiple nutrients and yield gaps. The method is demonstrated for crop production in the high‐rainfall zone of southern Australia. Data from a biophysical crop model were used to overcome the persistent problem of inadequate experimental data. The Mitscherlich function was expanded to accommodate four variable inputs – nitrogen, phosphorus, potassium and sulphur – and the expansion path was used to determine the economic optimum application of all four nutrients. Modelling revealed the state‐contingent yield potential and the extent to which unrealised yield could be explained by profit‐maximising behaviour and risk‐aversion by growers. If growers and their advisors were guided by the methods described, they would be better equipped to assess crop nutrient demands and limitations, predict yield potential, additional profit and the risks associated with high input systems in a variable climate. If scientists were more aware of the extra profits and the risks involved (as well as the quantitative relationships between inputs and outputs) when thinking about what to produce and how to do so, they would be more circumspect about the net benefits to be obtained from closing yield gaps.
