How Do Various Forms of Auditor Rotation Affect Audit Quality? Evidence from China

The Enron/Arthur Andersen scandal has raised concerns internationally about auditor independence, audit quality, and the need for regulatory action such as mandatory auditor rotation. China's unique institutional features provide a setting in which we can compare comprehensively the various forms of auditor rotation at different levels (partner vs. firm) and in different settings (voluntary vs. mandatory). In addition, institutional conditions vary dramatically across China, which provides us with an opportunity to test whether the development of market and legal institutions affects the impact of rotation on audit quality. We expect that auditors are less (more) constrained by market forces and less (more) self-disciplined to maintain audit quality in regions with less (more) developed market and legal institutions. Therefore, mandatory rotation may play a more (less) important role in less (more) developed regions. Using auditors' propensity to issue a modified audit opinion (MAO) as a proxy for audit quality, we find that firms with mandatory audit partner rotations are associated with a significantly higher likelihood of an MAO than are no-rotation firms. However, this effect is restricted to firms located in less developed regions. We find similar evidence for voluntary audit firm rotation although the significance level is much weaker than for mandatory partner rotation. Other forms of auditor rotations (i.e., mandatory audit firm rotation and voluntary audit partner rotation), have no effect on MAOs.     

Buyer-supplier relations in the UK - automotive industry: Strategic implications of the Japanese manufacturing model

This paper documents the adoption of the Japanese model of manufacturing in the U.K. motor industry. Internal developments by the vehicle assemblers and their suppliers are examined. It is argued that the Japanese model involves very high intra- and interorganizational dependencies. Although this does not cause problems in Japan due to the structure of the Japanese motor industry, the structure of the UK vehicle industry presents severe obstacles to the successful use of Japanese methods. Pursuit of the pure Japanese model within the existing industry structure appears to be fraught with problems. Moreover, such an exercise risks sweeping away potential strengths of the existing structure.     

Explaining Competitive Reactions to New Products: An Empirical Signaling Study

This article develops a conceptual model to help explain the strength of competitive reactions to new product introductions and presents the findings from a preliminary empirical investigation of this model. Being able to explain the strength of competitive reactions to new product introductions is important, as such reactions often determine a product's success or failure in the marketplace. To explain these reactions Oliver Heil and Rockney Walters investigate competitive market signals associated with new product introductions and the reactions of competing firms to the signals. The authors empirically test the hypothesized linkages among three market signals—hostility, consequences and commitment—and competitive reactions using primary data collected from a large number of US corporations. The empirical results show that the market signaling variables explain a significant portion of the variance in the perceived strength of competitive reactions to new product introductions. The study has implications for managers introducing new products and for researchers studying new product introductions and competition.     

Longevity and Genetic Improvement Issues in Replacing Dairy Cows

The objective of this research is to identify optimal economic replacement strategies for dairy cows within the framework of genetic improvement and to compare these strategies with those followed by Alberta dairy farmers. Production records from four commercial dairy herds are used to model the optimum replacement policy within a wealth-maximizing objective, allowing comparison of predicted results with observed practice in the industry. Unplanned replacement, due to biologial failure of cows, is included in the model as a finite Markov process. The economically optimal replacement time is found to occur at the end of the sixth lactation, with only minor penalties for suboptimality. Planned replacement after the sixth lactation requires culling approximately one quarter of the herd annually, and results in an average herd age of 5.77 years. Since the band of economically reasonable replacement policies extends from the third to the tenth lactation, the average herd age ranges from 4.48 years and 7.02 years. The observed average age of Alberta milking herds of 4. 78 years lies in the lower part of this predicted range. While one can conclude that the model leads to an optimum that is consistent with the observed behavior of Alberta dairy farmers, one must temper this conclusion with the caution that additional research, especially regarding the technical lactation curve, is indicated L'objet de la présente recherche était de dégager des stratégies de remplacement economiquement opti-males pour les vaches laitières, compte tenu des exigences de l'amelioration génétique, et de comparer ces stratégies avec celles qu'utilisent les producteurs laitiers de I 'Alberta. On a utilisé les relevés de production de quatre exploitations laitières commercials pour modéliser les stratégies de remplacement optimales dans un objectif de maximisation des revenus. Le modèle permet également de comparer les résultats prédits avec ceux observés sur le terrain. Les remplacements non prévus, à cause de défauts biologiques des vaches, étaient inclus dans le modèle comme processus de Markov fini. L'époque de remplacement économiquement optimale s'est révélée être le fin de la sixième lactation, avec seulement de légères pertes de rentabilité pour les situations suboptimales. Le remplacement planifié après la sixième lactation exigeait la mise à la réforme d'environ un quart du troupeau chaque année et donnait pour le troupeau un age moyen de 5,77 ans. Comme l'écart des possibilités de remplacement économiquement plausibles va de la troisième à la dixieme lactation, l'âge moyen des troupeaux se situe entre 4,48 et 7,02 ans. L'âge moyen réel des troupeaux laitiers de l'Alberta (4,78 ans) se situe dans le bas de eel écart de prédiction. Tout en reconnaissant que le modèle conduit à un optimum cohérent avec le comportentent réel des producteurs laitiers de l'Alberta, il reste qu'on a besoin de plus de recherche dans ce domaine, en particulier en ce qui concerne la courbe de lactation technique     

N.H. Stern on substance and method in development economics

Stern's observations on some major topics in development economics are examined, notably his interpretation of the hypothesis of the vicious circle of poverty, as well as his observations on the extent, movement and measurement of international income differences, the implications of central planning, and the effects of development aid. Issues of both substance and method are examined. The inadequacies of some leading ideas of development economics, defended by Stern, are considered. Significant instances of inappropriate aggregation and quantification are noted, as well as some results of the treatment as parameters of factors which are regarded appropriately as variables. Problems of assessing evidence, including assessment of the effects of policies, are also discussed.     

ADOPTING JAPANESE-STYLE MANUFACTURING METHODS: A TALE OF TWO (UK) FACTORIES*

Japanese manufacturing methods such as just-in-time production and total quality control are serving as a model of manufacturing organization which many UK manufacturers are currently emulating. This article describes the implementation of just-in-time production and its supporting practices in two factories owned by the same company. Empirical evidence demonstrates a profoundly political dimension to these innovations, requiring a significant rewriting of organizations’ political and cultural maps.

Can satellite‐based weather index insurance improve the hedging of yield risk of perennial non‐irrigated olive trees in Spain?*

Olive oil yields fluctuate strongly due to their dependence on sufficient precipitation. An interesting option to hedge the yield risk in olive cultivation could be satellite‐based weather index insurance. Therefore, we implement index insurance as a hedging alternative for non‐irrigated olive groves using MODerate‐resolution Imaging Spectroradiometer (MODIS) satellite data. For this purpose, we focus on the Spanish region of Andalusia, given its importance in olive production at the international level. We calculate three satellite indices: the Vegetation Condition Index (VCI), the Temperature Condition Index (TCI) and the Vegetation Health Index (VHI). Meteorological indices related to temperature and precipitation are used as benchmarks. Firstly, we estimate the periods that have the greatest influence on the critical vegetative phase of olives, which extends from March to September. Based on the indices, insurance contracts are designed using a copula approach, which is then employed to evaluate their hedging effectiveness. On average, the hedging effectiveness of VCI‐, VHI‐ and TCI‐based weather index insurance contracts amounts to 38 per cent, 38 per cent and 29 per cent, respectively. Moreover, VCI‐ and VHI‐based weather index insurance contracts outperform traditional weather index insurance contracts based on precipitation (by 29 per cent) and temperature (by 16 per cent) indices.
