Abstract: We model the strategic as well as the operational dimension of performance of supplier–retailer partnerships in terms of five factors: (1) information exchange; (2) trust; (3) joint partnership management; (4) relationship-specific assets; and (5) partner asymmetry. Our paired data are from 74 supplier–retailer partnerships in the consumer-packaged goods industry. As a result we found that the factors that best model strategic performance are different from those that best model operational performance. All companies are in Korea and the retailers include international companies like Carrefour, Tesco, and Wal-Mart while suppliers include Coca-Cola, Kimberley-Clark, and Nestlé.

Abstract: This questionnaire-based study investigated the relationship between two aspects of leadership (charismatic leadership and trust in top management) and followers’ innovation implementation behavior. Findings from 194 employees working in R&D teams of a multinational automotive company indicated that charismatic leadership and trust in top management were both positively related to innovation implementation behavior, controlling for followers’ individual differences, management level, and department affiliation. The findings demonstrate that both relationships were mediated by followers’ affective commitment to change. Results implicate the need to more closely bond the concepts of affective commitment to change and innovation implementation behavior and consider their connection in future investigations.

Abstract: Two large online surveys were conducted among employees in Germany to explore the importance employees and organizations place on aspects of interpersonal respect in relation to other work values. The first study (n = 589) extracted a general ranking of work values, showing that employees rate issues of respect involving supervisors particularly high. The second study (n = 318) replicated the previous value ranking. Additionally, it is shown that the value priorities indicated by employees do not always match their perceptions of actual organizational practices. Particularly, interpersonal respect issues that involve employees’ supervisors diverge strongly negative. Consequences and potentials for change in organizations are discussed.

Abstract: We extend the linear programming (LP) model of deterministic supply-chain planning to take demand uncertainty and cash flows into account for the medium term. The resulting stochastic LP model is similar to that of asset–liability management (ALM), for which the literature using stochastic programming is extensive. As such, we survey various modeling and solution choices developed in the ALM literature and discuss their applicability to supply-chain planning. This survey can be a basis for making modeling/solution choices in research and in practice to manage the risks pertaining to unmet demand, excess inventory, and cash liquidity when demand is uncertain.

Abstract: Regulations regarding drivers’ working hours often have a big impact on total transit times, i.e., the time required for driving periods, breaks, and rest periods. Although of particular importance for many real-life applications, they have received only very little attention in the vehicle routing literature. This paper describes the new regulations for drivers’ working hours in the European Union that entered into force in April 2007. According to the new regulations, motor carriers must organise the work of drivers in such a way that drivers are able to comply with the respective regulations and are made liable for infringements committed by the drivers. This paper shows how motor carriers can schedule driving periods, breaks, rest periods, and handling activities, and presents a large neighbourhood search algorithm capable of generating vehicle tours complying with the new regulations.

Abstract: Since the beginning of the 1990s cost management is widely discussed on a conceptual basis. Empirical research is mainly focused on special aspects of cost management. Especially, target costing is empirically analyzed. The results indicate the effectiveness of target costing, while some studies criticize its complexity and its results in terms of overengineered products. In general, empirical results with regard to cost management are very fragmented and ignore very often theoretical contributions. Particularly, empirical research neglects behavioral aspects of cost management. These behavioral aspects are important since theoretical research implies that cost management provokes opposition in business companies. With regard to the methodology the derived results are mainly based upon case studies and small samples within a special industrial environment. The data analysis is generally descriptive and does not allow to derive any managerial implications. Therefore, there is a lack of empirical conclusions with regard to which success factors are relevant in the context of cost management.

Abstract: This paper proposes a definition for financial market stability and an econometric test. It analyzes the impact of systematic and systemic shocks on developed and emerging market stock indices in normal and extreme market conditions. Financial market stability is defined as a constant impact of systematic shocks in normal and extreme market situations. Empirical results show that the impact of systematic shocks is significantly larger in extreme market conditions than in normal conditions for emerging markets. In contrast, the relationship is stable for developed markets. Hence, only developed markets meet an essential condition for financial market stability.

Abstract: This article is the first to study momentum trading strategies in the Irish stock market. The findings can be summarized as follows: (i) unconditional momentum trading strategies do not outperform the market, (ii) winner and loser trading strategies do outperform the market and (iii) controlling for heteroscedasticity significantly changes the results and yields positive and significant excess returns for most of the 16 momentum trading strategies analysed. These findings illustrate that investors can persistently earn excess returns in the Irish stock market.

Abstract: This paper proposes a multivariate test to measure the statistical and economic significance of contagion through analysis of extreme unobserved common shocks. Contagious episodes are endogenously determined with no need, but the possibility, to specify the source country. Application to a panel of equity returns during the Asian crisis of 1997–1998 finds that interdependencies are substantially more important than contagion. However, the periods of contagion evident show that it is short-lived, split between positive and negative movements and reverses quickly. In comparison to other Asian crisis countries, Hong Kong is the main driver of contagion in the crisis. The proposed methodology and the empirical findings provide a more detailed picture of contagion than commonly applied tests.

Abstract: This paper proposes the use of global sensitivity analysis to evaluate the risk associated with a credit portfolio model. Although successfully applied in many disciplines such as chemistry, biology and environmental science, the use of global sensitivity analysis is still rare in financial contexts. One-at-a-time sensitivity analysis is usually applied despite its shortcomings. The scope of this paper is to demonstrate the advantages of a more comprehensive analysis, that is a global sensitivity analysis. As an example, following the works by Frey et al. (2001) and Kiesel and Kleinow (2002), we analyse the static and time-varying uncertainties of three inputs in a latent factor credit risk model: the multivariate distribution of the latent variables, the correlation, and the default probabilities of the obligors. Results show that the relative importance of the inputs strongly depends on the average default probability of the portfolio and the analysed quantiles of the default distribution.

Abstract: Service composition on the Grid is a challenging task as documented in existing research work. Even though there are initial attempts to use the Business Process Execution Language (BPEL) to compose services on the Grid, still there is a significant lack of flexibility and reusability needed in scientific applications. In this paper we present BPEL for Semantic Web Services (BPEL4SWS) – a language that facilitates the orchestration of Grid Services exposed as traditional Web Services or Semantic Web Services using a process-based approach. It is based on the idea of WSDL-less BPEL and incorporates semantic descriptions of process activity implementations which increases the flexibility of business workflows as well as scientific workflows. Following an approach that uses a set of composable standards and specifications, BPEL4SWS is independent of any Semantic Web Service framework and therefore can also utilize any kind of Semantic Grid services. The advantages of BPEL4SWS are: (1) compliance with standards, (2) independence on service technologies, (3) applicability for both business applications as well as scientific workflows that use Grid services, (4) improved flexibility of processes.

Abstract: The Basel II accord encourages banks to develop their own advanced measurement approaches (AMA). However, the paucity of loss data implies that an individual bank cannot obtain a probability distribution with any reliability. We propose a model, targeting the regulator initially, by obtaining a probability distribution for loss magnitude using pooled annual risk losses from the banks under the regulator’s oversight. We start with summarized loss data from 63 European banks and adjust the probability distribution obtained for losses that go unreported by falling below the threshold level. Using our model, the regulator has a tool for understanding the extent of annual operational losses across all the banks under its supervision. The regulator can use the model on an ongoing basis to make comparisons in year-on-year changes to the operational risk profile of the regulated banking sector.

Abstract: Open source software development has received considerable scholarly attention, much of which is based on the presumption that the ‘open source model’ holds some lessons of broader applicability. Nonetheless, our knowledge of its deployment outside the software industry is very limited. This paper focuses on the open source development of tangible objects, the so-called open design. We propose a generalised definition of open source development. Drawing on 27 exploratory interviews and six comparative case studies selected from a pool of more than 75 projects, we analyse the workings of open design. The analysis reveals that open design is already being implemented in a substantial variety of projects with different organisational and institutional structures.
