The psychological contract and the transition from office‐based to home‐based work

This article explores how the transition from office‐based to home‐based work impacts upon the psychological contracts of employees involved. Adopting a qualitative case study approach, utilising a short‐term longitudinal design, the setting is a local authority which implemented a 3‐month home‐working pilot scheme. Using the psychological contract as an analytical framework it is shown how the implementation of the changes impacts upon the psychological contracts not only in the workplace but also in the home. In both the arenas of work and the home, obligations are surfaced (and sometimes renegotiated) and boundaries are redrawn. The relationship with the employer becomes increasingly transactional, enabling participants to redefine the status of work in relation to their other priorities. Whilst homeworkers exhibit an increased commitment to the mode of work and become more productive for their employer, they also exhibit a more transactional orientation to work, threatening to leave if homeworking is withdrawn. We explore the methodological and theoretical implications of our findings drawing attention to the analytical potential of the psychological contract for generating more critical insights.     

Cost Inefficiency,Size of Firms and Takeovers

This study, using the Cox proportional hazards model, finds that the risk of takeover rises with cost inefficiency. It also finds that a firm faces a significantly higher risk of takeover if its cost performance lags behind its industry benchmark. Moreover, these findings appear to be remarkably stable over the nearly two decades spanned by the sample. The effect of the variables used to measure the risk-size relationship, however, indicates temporal changes. Lastly, the study presents evidence from fixed-effects models of ex post cost efficiency improvements that support the hypothesis that takeover targets are selected based on the potential for improvement.     

Demand elasticity estimates for New Zealand tourism

Demand elasticities for New Zealand tourism are estimated for 16 different international visitor segments. Segments are differentiated by origin, purpose of visit, and travel style. Elasticities for both international visitor arrivals and on-the-ground expenditure per arrival are estimated for each segment using time-series data. In general, on-the-ground consumption per arrival is more price sensitive than number of arrivals, and Asian market segments are found to be more price sensitive, both in terms of arrivals and on-the-ground expenditure, compared to international visitors from other regions. An application of the results is presented giving the total effect of exchange rate changes on expenditure by international visitors in New Zealand, and management implications are discussed.     

Arbeiten 4.0 — Folgen der Digitalisierung für die Arbeitswelt

Digitalisation will not only lead to the disappearance of jobs, the creation of new jobs and changing skill requirements in many existing jobs. It also leads to fundamental challenges for existing qualification systems as well as labour law and labour relations. New digital technologies pervasively change the content and organisation of work. They may have an impact on the actual weekly working time hours and the adoption of self-managed working time systems. The consequences, however, may differ for each worker. Accordingly, economic and policy conclusions cannot be derived for the labour market as a whole. Workers‘qualifications need not only to be adapted to changing occupational tasks. Work intensification and increasing communication flows have to be addressed as well. Furthermore, adequate human resources policies can foster the proper use of new flexible work arrangements. Crowdworking as a specific form of flexible work, however, has to be primarily integrated in existing labour legislation. That is one opinion, another author considers the forecasts doomsday prophecies that call for political action or amending the regulative framework. And he suggests that the characteristics of the digital transformation of work may mainly be firm-specific. In a social-scientific perspective there is no deterministic relationship between technology and work but the development of work has to be regarded as a strategic and political design project.     

Places and Spaces: The Role of Metonymy in Organizational Talk

Cultural meaning making as reflected in, and constituted by, organizational talk is an established field of interest in organizational analysis. However, the discursive mechanics of the process whereby this cultural meaning making is created and maintained are less well understood. The premise of this paper is that taken‐for‐granted assumptions embedded in organizational talk can be explored through the analysis of metonymy, a trope which is under explored in the linguistic turn in organization studies. This lack of focus on metonymy is, we believe, related to the fundamentally conventional nature of the trope in use, which expresses ideas, values and relationships that seem natural, normal and routine but which are culturally bound. We address this gap and carry out a metonymical analysis of organizational talk about physical places and spaces in one organization, to show how cultural norms and meanings are reflected, maintained, and potentially changed in these figures of speech. We show how metonymic chains based on buildings can reflect, reify and simplify the symbolic order of the organization, how these symbolic meanings can be transferred on to other inanimate objects and the constructions thereby spread, how people can be constructed within this symbolic chain, and how these metonymic chains can be invoked to potentially confirm, challenge or change the organizational order.     

Optimal portfolios when stock prices follow an exponential Lévy process

We investigate some portfolio problems that consist of maximizing expected terminal wealth under the constraint of an upper bound for the risk, where we measure risk by the variance, but also by the Capital-at-Risk (CaR). The solution of the mean-variance problem has the same structure for any price process which follows an exponential Lévy process. The CaR involves a quantile of the corresponding wealth process of the portfolio. We derive a weak limit law for its approximation by a simpler Lévy process, often the sum of a drift term, a Brownian motion and a compound Poisson process. Certain relations between a Lévy process and its stochastic exponential are investigated.Received: January 2003Mathematics Subject Classification: Primary: 60F05, 60G51, 60H30, 91B28; secondary: 60E07, 91B70JEL Classification: C22, G11, D81We would like to thank Jan Kallsen and Ralf Korn for discussions and valuable remarks on a previous version of our paper. The second author would like to thank the participants of the Conference on Lévy Processes at Aarhus University in January 2002 for stimulating remarks. In particular, a discussion with Jan Rosinski on gamma processes has provided more insight into the approximation of the variance gamma model.     

Trade-Related Intellectual Property Rights, North-South Trade, and Biological Diversity

In the Trade-Related Intellectual Property Rights (TRIPS) Agreement of GATT (1 January 1995) it was agreed to harmonise intellectual property rights (IPR) on an international level and to include the option for patent protection for all life forms such as plants and animals (Article 27 (3) b). Patenting, however, leads to considerable conflicts between international trade and protection of biological diversity, which can be illustrated by the example of seed production. We make use of a three-stage game to show the strategic incentives for implementation of two different property rights regimes (patents and farmers' rights) on competition and biodiversity. We show that the Southern government has no incentive to acknowledge international patents, even if farmers' rights do exist. The Northern producer will always dominate in the output market if patents are applied, but without farmers' rights biodiversity will not be maintained by the Southern government. Thus total payoff of the northern firm is maximized, if both IPR regimes are implemented. However, if only farmers' rights are valid, biodiversity will be maximal.     

Should Banks Be Banned From Creating Money? An Analysis From the Perspective of Hierarchical Money

We extend the concept of “hierarchy of money” to our current monetary and financial system based on fiat money, with monetary policy that is conducted through the sale and purchase of securities and credit intermediation by non-bank financial intermediaries. This exposes a feedback loop between the upper and lower level of the hierarchy, which allows for more than full use of otherwise dormant capital, but that also increases inherent instabilities manifested in asset booms and busts. From the perspective of hierarchical money, we find that the call to ban banks from creating money neglects the significant role of securities-based financing in the global financial markets at the lower level, as well as the money creation capacity of central banks at the highest level of the hierarchy. Moreover, the inherently expansive nature of the hierarchy of money contradicts the long-term feasibility of full-reserve banking.
