Respect and relational contracts

Assuming that people care not only about what others do but also on what others think, we study respect in a labor market context where the length of the employment relationship is endogenous. In our three-stage gift-exchange experiment, the employer can express respect by giving the employee costly symbolic rewards after observing his level of effort. We study whether symbolic rewards are used by the employers mainly to praise employees or as a coordination device to build relational contracts by manipulating the balance between labor demand and supply in the market. We find that a high proportion of long-term relationships have been initiated by the assignment of symbolic rewards. However, the assignment of symbolic rewards decreases when it becomes clear that the relationship is durable, suggesting that employers mainly use symbolic rewards as a coordination device to initiate relational contracts. Compared to the balanced market condition, assigning symbolic rewards in initial relationships is less likely when there is excess demand in the market and more likely when there is excess supply, i.e., when the relationship is more valuable. Receiving symbolic rewards increases the employees’ likelihood of accepting to continue the relationship with the same employer. It also motivates them to increase their effort further but only when the market is balanced. Overall, the ability to assign symbolic rewards does not give rise to higher profits because it is associated with lower rents offered to the employees on average, leading to lower effort levels.     

Auditor liability rules under imperfect information and costly litigation: the welfare-increasing effect of liability insurance

This paper examines auditor liability rules under imperfect information, costly litigation and risk-averse auditors. A negligence rule fails in such a setting, because in equilibrium auditors will deviate with positive probability from any given standard. It is shown that strict liability outperforms negligence with respect to risk allocation and the probability that a desired level of care is met by the auditor if competitive liability insurance markets exist. Furthermore, our model explains the existence of insurance contracts containing obligations a type of contract often observed in liability insurance markets.     

Adoption of network technologies in the presence of converters

In many high-tech industries, the emergence of new digital technologies allows companies to develop converters to overcome technology incompatibility. In this paper, we analyze the effects of converter introduction on the adoption process of competing, incompatible technologies in the presence of network externalities. Converter introduction may accelerate, extend or reverse the technology lock-in process. We determine which conversion options are profitable for weak as well as for dominant incumbents, depending on the timing of converter introduction and the degrees of conversion. We find that the optimal strategy for weak incumbents is to introduce full one-way converters early. For dominant incumbents, the optimal conversion option is to provide two-way converters with partial compatibility for the users of the competing network at a later introduction time. We illustrate our analytical results with numerical examples.     

Bridging and bonding forms of social capital in a regional strategic network

Research on networks emphasizes the importance of bonds between actors. Social reciprocity strengthens network bonds, which is assumed to have positive effects on business relationships between firms. However, the importance of weak ties is also stressed in network research. An important policy issue is therefore if more attention should be devoted to the creation of bridges to other social groups and loosening bonds between network actors. The difficulty in doing so is described and analyzed in this article focusing on a regional strategic network, which is viewed in three network perspectives. Interview data were collected from all participating managers in a regional strategic network in 2004 and 2010. The findings shed light upon the paradox of using a regional strategic network to counteract over-embeddedness and freeing the involved actors from existing network lock-ins instead of further strengthening such social institutions.     

Doing by learning: Embedded application systems

We argue that the computerized information system should not look like a system on its own. Rather, it should be conceived as an inherent part of the work of its users. We therefore introduce the concept of an embedded system, which describes work tasks and organization. Computer‐supported information tasks are embedded in this environment: They are not parts of a system separated from other activities. This concept is based on the experiences gained during the development of a user‐interface prototype, derived from a theoretical frame of reference, called act orientation, to information systems, in which all computerized tasks are interpreted as acts performed by the actual user. Our suggestion continues the tradition of on‐line help and support, reaching radically deeper than usual in related approaches. We expect that our suggestion will, when applied, improve the control, productivity, quality of the outcome of work, and quality of working life, assessed from the user's point of view.     

HRM Practices and the Within‐Firm Gender Wage Gap

The effect of HRM practices on the within‐firm gender gap in wages in manufacturing is investigated merging a 1999 survey on work practices among Danish firms to matched employer–employee panel data. Self‐managed teams, project organization and job rotation schemes are the most widely introduced practices. Accounting for non‐randomness in adoption, the pay gap is reduced among hourly paid workers but increases among salaried workers. Considering practices individually, wage gains from adoption accrue to males except for salaried workers in firms that adopt project organization and for hourly paid workers in firms that introduce quality control circles.     

Project portfolio control and portfolio management performance in different contexts

This article investigates the nature and relationship of project portfolio control techniques and portfolio management performance, and how this relationship is moderated by situational idiosyncrasies of internal and external dynamics, industries, governance types, and geographic location. A worldwide questionnaire with 242 responses was used, of which 136 high‐performing responses were filtered out for quantitative analysis of best practices. Three portfolio control factors were identified: portfolio selection, portfolio reporting, and decision‐making style. Two measures for portfolio management performance were identified: achievement of desired portfolio results and achievement of project and program purpose. The results indicate that different portfolio control mechanisms are associated with different performance measures. A contingency model was developed, including moderating effects by contextual variables.     

Return performance volatility and adaptation in an automated technical analysis approach to portfolio management

This paper discusses the design of a quantitative computational intelligence portfolio management system and evaluates the advantages of some adaptive mechanisms to enable the system to adjust its management approach as market conditions change. A detailed analysis of the performance of the system outside is also provided. It is found that an adaptive methodology where trading rules are able to adjust to market conditions performs better, having greater excess returns and lower volatility than a fixed rule approach. We consider several performance metrics, including portfolio alpha and information content. Copyright © 2009 John Wiley & Sons, Ltd.     

KSA – Beitritt oder Gründung nicht ausschreibungspflichtig

All in all it can be stated that both, the establishment and the joining of a KSA, is an activity which is exclusively allocated to the right of self organisation of the local authorities. It is a measure of internal organisation without external procurement character. For this reason from the first the application of the procurement rules following the competition law is already excluded.Even if – in contrary to other argumentation – the competition law rules should be regarded as applicable, the principle of in-house award exceptionally takes effect.
