User-oriented product innovation - Some research findings

Successful product innovation requires information about user needs. The provision of such information is a question both of attitudes and methods. A number of leading companies in Europe, Japan and the U.S.A. demonstrate the importance of a market-oriented attitude and close contact with users. In-depth studies in Germany, Italy and Norway have revealed an array of tools that are available for the systematic assessment of existing and future needs.Most firms will benefit from a stronger market orientation. However, if one moves too far in this direction, societal needs may be neglected and technological opportunities missed. The aim should be a balanced orientation where the needs of all stakeholders are taken into consideration.     

Spatial dependencies and spatial drift in public transport seasonal ticket revenue data

When firms' customers are located in spatially dispersed areas, it can be difficult to manage service quality on a geographically small scale because the relative importance of service quality might vary spatially. Moreover, standard approaches discussed so far in the marketing science literature usually neglect spatial effects, such as spatial dependencies (spatial autocorrelation for example) and spatial drift (spatial non-stationarity). We propose a comprehensive approach based on spatial econometric methods that covers both issues. Based on the real company data on seasonal ticket revenue of a local public transport service company, we show that addressing such spatial effects of service data can improve management's ability to implement programs aimed at enhancing seasonal ticket revenue. In particular, the article shows how a spatial revenue response function might be specified.     

Job search incentives and job match quality

We examine the impacts of time-limited unemployment insurance (UI) and active labor market programs (ALMP) on the duration and outcome of job search in Norway. We use a comprehensive simultaneous equations model accounting for i) the duration of unemployment spells; ii) their outcomes, iii) subsequent employment stability; and iv) the earnings level associated with the first job. We find that time invested in job search pays off in form of higher earnings once a job match is formed. ALMP raises the probability of eventually finding a job as well as expected earnings, but at the cost of lengthening job search.     

Regional differences in small firm entry in manufacturing industries: Lower Saxony, 1979–1991 †

This paper is an empirical study of inter-regional and inter-temporal variations in entry of new firms using longitudinal data covering all manufacturing establishments in Lower Saxony between 1979 and 1991. Patterns of entry are reported for sixteen regions based on gross rates of entry (number of new firms) and entry intensities (shares of employees). An empirical model is applied to detect regional characteristics that are highly correlated with entry. Pooling of cross-section and time-series data allows for control of influences of varying macroeconomic conditions and unobserved regional characteristics that turned out to be important. Small firm entry tends to be positively related to high overall economic growth, and to be higher in regions where both the small firm employment share and the level of wealth are high while the wage rate is low. We find no evidence for a negative impact of the business tax rate or for a positive effect of regional subsidies.     

On the St. Petersburg Paradox

The classical St. Petersburg Paradox is discussed in terms of doubling strategies. It is claimed that what was originally thought of as a ''paradox'' can hardly be considered as very surprising today, but viewed in terms of doubling strategies, we get some results that look paradoxical, at least to the practically oriented investor.     

Green promotes the dirtiest: on the interaction between black and green quotas in energy markets

Tradable black (CO₂) and green (renewables) quotas gain in popularity and stringency within climate policies of many OECD countries. The overlapping regulation through both instruments, however, may have important unintended consequences. Based on theoretical analysis we show that a green quota imposed on top of a black quota promotes power production by the dirtiest technologies as compared to a black quota regime only.     

An extended production/recycling model with stationary demand and return rates

A production–recycling system is investigated. A constant demand can be satisfied with production and recycling. The used items are bought back and then recycled. The non-recycled products are disposed of. Two types of models will be analyzed. The first model examines the EOQ-related costs and minimizes the relevant costs. The second model generalizes the first model with the introduction of the cost function with linear waste disposal, recycling, production and buyback costs. It is asked whether the pure (either production or recycling) or mixed strategies are optimal and it will be shown that under these circumstances the mixed strategies are dominated by the pure strategies. The paper generalizes a former model proposed by the authors for the case of one recycling and one production batch to the case of arbitrary batch numbers.     

From natural resources and environmental accounting to construction of indicators for sustainable development

Norway has a long history in trying to develop management tools for sustainable development. From the early development of natural resources accounts in the 1980s, through discussions of the usefulness of indices like “green GDP” to efforts of developing sustainable development indicators, experiences have been gained. The paper seeks to both describe the landscape and discussions associated with the key terms, and to communicate some lessons drawn from the Norwegian experiences. The conclusion focuses on the fact that whatever information is collected and organised to support the relevant decision-making processes, the final outcome should always be judged in terms of its impacts on policy processes. Thus, we issue a warning against large-scale development of information systems, without due regard to the final utilisation of the output.     

Exploring the interaction of firm-level change and national institutional environments in shaping employment and union relations: a comparative case study of four European airlines

Drawing on the example of the airline industry, this paper explores in a longitudinal comparative case study the question of how firm-level changes and national institutional environments interact in shaping employee and union relations. Adding to previous research in comparative institutional analysis and comparative employment relations, we illustrate that the way in which industry pressures and national-level effects play out to influence employee and union relations depends on firm-level changes, mainly in the form of firm growth, acquisitions and the foundation of new subsidiaries. We show in particular that depending on firm-level changes, the very same firm might engage differently with a given institutional context at different points in time. Hence, our work illustrates the importance of firm growth, acquisitions and the foundation of new subsidiaries in explaining the shifting interaction between the firm and its institutional environment, and its implications for changing employee and union relations within firms.
