Strategic Manipulation of Preference Information in Multi-Criteria Group Decision Methods

When group decisions involve the allocation of resources to group members, the members might have an incentive to strategically distort any information they provide in order to increase their share of resources. The paper compares several multi-criteria group decision methods with respect to this problem. We show, using a computational model, that strategic manipulation of preference information is possible in all of the methods considered, although to a different extent. Furthermore, when the solution a method generates under correct information is not Pareto-optimal, manipulation attempts might even improve the efficiency of outcomes.     

Lags and Leads in Life Satisfaction in Korea: When Gender Matters

Using detailed longitudinal data from the Korean Labor and Income Panel Study (KLIPS) from 1998 to 2008, this paper finds significant gender differences in impacts as well as adaptation patterns to major life and labor market events in Korea. Men remain on a higher happiness level throughout marriage, while women return to their baseline happiness within only two years. Consequently, men suffer more from divorce and the death of a spouse. This marital gender happiness gap is equivalent to a (husband only) increase of annual per capita household income of approximately US$17,800. The study further finds that men suffer more from unemployment. Results are robust to the inclusion of multiple simultaneous events and the use of different estimators.     

Preference Structures of Negotiators and Negotiation Outcomes

Using a database collected during about 3,000 negotiation experiments, this paper analyzes how specific features of utility functions of negotiators, like attribute weights, monotonicity and convexity of marginal utility functions, are reflected in the outcomes of negotiations. We find that compromise values are to a considerable extent influenced by the utility functions. There are also significant impacts on the likelihood of achieving a compromise, but the model fit is considerably less than for compromise values.

Understanding the impact of relational capital and organizational learning on alliance outcomes

This paper examines how relational capital influences the acquisition of knowledge among alliance partners. We propose that firms with higher levels of inter- and intrafirm learning are better able to achieve superior alliance outcomes. A conceptual framework is developed by integrating the relational view, organizational learning theory, and the resource-based view. We provide empirical evidence using large-sample data to test the model and find that trust and interaction creates a basis for knowledge acquisition across alliance partners. The results also indicate that when the firms are active in knowledge acquisition from alliance partners and dissemination of such knowledge within the organization, they are capable of enhancing satisfaction with the alliance relationship.     

Procurement of logistics services and sustainable development in Europe: Fields of activity and empirical results

This paper strives to answer the general question; how far purchasers of logistics services take into account aspects of sustainable development. Modeled on the German Sustainable Development Strategy, which is based on the EU Sustainable Development plan, five fields of activity are defined: the reduction of transport intensity and emission, the reduction of land use, the choice of carrier under consideration of sustainable aspects, the permanent improvement of working conditions, and the enhancement of qualified employment. Then, propositions for purchasing companies of logistics services are developed, which contribute to safeguard ecological as well as social sustainability. In order to conduct an explorative study, a questionnaire was sent to 750 purchase and logistics managers. It was found that purchasing companies place high value on ecological and social aspects. But the perceived importance is not associated with purchasing companies' own contributions to logistics service providers' sustainable activities. Additionally, it was seen that purchasing companies exert only a minor influence on logistics service providers regarding ecologically and socially sustainable actions. A fundamental precondition for a sustainably oriented procurement of logistics services can be seen in the purchasing companies' awareness of the need for integrating sustainable aspects in economic decisions.     

Orthogonalized factors and systematic risk decomposition

In the context of linear multi-factor models, this study proposes an egalitarian, optimal and unique procedure to find orthogonalized factors, which also facilitates the decomposition of the coefficient of determination. Importantly, the new risk factors may diverge significantly from the original ones. The decomposition of risk allows one to explicitly examine the impact of individual factors on the return variation of risky assets, which provides discriminative power for factor selection. The procedure is experimentally robust even for small samples. Empirically we find that even though, on average, approximately eighty (sixty-five) percent of style (industry) portfolios’ volatility is explained by the market and size factors, other factors such as value, momentum and contrarian still play an important role for certain portfolios. The components of systematic risk, while dynamic over time, generally exhibit negative correlation between market, on one side, and size, value, momentum and contrarian, on the other side.
