MCMC ESTIMATION OF LÉVY JUMP MODELS USING STOCK AND OPTION PRICES

We examine the performances of several popular Lévy jump models and some of the most sophisticated affine jump‐diffusion models in capturing the joint dynamics of stock and option prices. We develop efficient Markov chain Monte Carlo methods for estimating parameters and latent volatility/jump variables of the Lévy jump models using stock and option prices. We show that models with infinite‐activity Lévy jumps in returns significantly outperform affine jump‐diffusion models with compound Poisson jumps in returns and volatility in capturing both the physical and risk‐neutral dynamics of the S&P 500 index. We also find that the variance gamma model of Madan, Carr, and Chang with stochastic volatility has the best performance among all the models we consider.     

The Impact of Size,Stock Market Listing and Industry Type on Disclosure in the Annual Reports of Japanese Listed Corporations

This paper represents a contribution to rigorous testing of Japanese financial reporting and specifically reports on the impact of size, stock market listing and industry type on disclosure, both voluntary and mandatory, in the annual reports of Japanese listed corporations. The topic is of interest because findings in one country may not be applicable to Japan because of its so-called unique business environment and unique culture. It is found that size and listing status are important explanatory variables. In addition, manufacturing corporations were found to disclose significantly more information than other types of Japanese corporations. The interaction between industry type and quotation status was also found to be significant.     

Strategic management accounting in close inter-organisational relationships

This paper provides a conceptual comparison between the ‘mainstream strategic management accounting’ literature, the ‘accounting and strategising’ literature and ‘strategic management accounting (SMA) in close inter-organisational relationships’. It concludes that ‘SMA in close inter-organisational relationships’ shares some important characteristics with the ‘accounting and strategising’ literature. Important differences were found, too, though. These mainly concerned the need to understand individuals working for close partners as preparers of strategic information; the need for disaggregated accounting information about unique connections to close partners and about the role of indirect benefits that follow from close connections and the need for the company to not only collect information but also disperse diverse information within close inter-organisational relationships. Through an intensive case study of a global robot manufacturer, Robotics, this paper also provides novel empirical evidence on ‘SMA in close inter-organisational relationships’. For instance, SMA practices included indirect benefits, something mainly neglected in the existing literature on SMA. These indirect benefits involved a close customer's willingness to invest time and effort in Robotics’ technological development, thereby contributing to Robotics’ ability to attain revenue gains in its interactions with other customers. Our findings also have important implications for the ‘inter-organisational accounting’ literature, for instance, by highlighting the need to link more explicitly strategic decision-making with the current interest in the role of accounting in inter-organisational dynamics.     

Control-based channel governance and relative dependence

Control and governance theories recognize that exchange partners are subject to two general forms of control, the unilateral authority of one firm and bilateral expectations extending from their social bond. In this way, a supplier both exerts unilateral, authority-based controls and is subject to socially-based, bilateral controls as it attempts to manage its brand successfully through reseller channels. Such control is being challenged by suppliers’ growing relative dependence on increasingly dominant resellers in many industries. Yet the impact of supplier relative dependence on the efficacy of control-based governance in the supplier’s channel is not well understood. To address this gap, we specify and test a control model moderated by relative dependence involving the conceptualization and measurement of governance at the level of specific control processes: incenting, monitoring, and enforcing. Our empirical findings show relative dependence undercuts the effectiveness of certain unilateral and bilateral control processes while enhancing the effectiveness of others, largely supporting our dual suppositions that each control process operates through a specialized behavioral mechanism and that these underlying mechanisms are differentially impacted by relative dependence. We offer implications of these findings for managers and identify our contributions to channel theory and research.     

Application of early risk detection concepts and methods to environmental health. A German feasibility study

Early risk detection is essential for being able to address the most important environmental health risk‐topics in a persistent and prospective manner. In support of the action programme “Environment and Health” (APUG) of the German Federal Ministry of Health and Social Security (BMGS) and the Federal Ministry for the Environment, Nature Conservation, and Nuclear Safety (BMU) which recommended that a detection and evaluation system for the timely recognition of emerging risk problems be developed, a qualitative feasibility study was commissioned. The results of this study are presented here and support the development of an early risk detection system based on the insights gained from the investigation of case studies and the differentiation and presentation of a risk typology, methods, tools, and suggested organizational processes.

The study has shown that early risk detection includes the identification, characterization, evaluation and dissemination of information on possible risks as well as the circumstances of appearance and distribution. The goal is the recognition of possible risks in order for risk management to be able to introduce swift and appropriate measures. Consequently, it can also serve as an instrument towards further development of a balanced and structured implementation of the precautionary principle in the environmental health policy.     

Multinationals and human resource practices in Ireland: a rejection of the 'new conformance thesis': a reply

This paper reports on a study of 398 people employed in two UK service organizations: a hospital and two divisions of a high street bank. The main purpose of the study was to determine the degree to which dispositional factors (predisposition to trust and trait anxiety) and situational factors (seven aspects of the job environment) predicted a person's reported trust in their managers. Two types of managers were investigated: a person's immediate line manager and ‘senior managers in their industry’. It was hypothesized that the dispositional factors would have a greater influence on trust in managers in the industry and that situational factors would have a greater influence on trust in one's immediate line manager. The first hypothesis was supported, but the second was not. It was found that trust in both types of managers was best predicted by a combination of general disposition to trust (not trait anxiety) and situational factors: five of the seven situational factors had a role in predicting intention to trust. This reflects the complexity involved in predicting trust at work and the managerial challenge of creating a trusting culture.     

Efficiency in the international insurance industry: A cross-country comparison

The purpose of this paper is to provide new empirical evidence on frontier efficiency measurement in the international insurance industry, a topic of great interest in the academic literature during the last several years. A broad efficiency comparison of 6462 insurers from 36 countries is conducted. Different methodologies, countries, organizational forms, and company sizes are compared, considering life and non-life insurers. We find a steady technical and cost efficiency growth in international insurance markets from 2002 to 2006, with large differences across countries. Denmark and Japan have the highest average efficiency, whereas the Philippines is the least efficient. Regarding organizational form, the results are not consistent with the expense preference hypothesis, which claims that mutuals should be less efficient than stocks due to higher agency costs. Only minor variations are found when comparing different frontier efficiency methodologies (data envelopment analysis, stochastic frontier analysis).
