Egalitarian wage policies, unemployment and skill-biased technological change

A popular explanation for the rise in European unemployment during the past decades is that relative wages failed to adjust to changes in relative productivities. Many economists reject this hypothesis on the ground that the ratios of low- to high-skill unemployment did not increase. Building on a search model, I argue that relative unemployment rates are affected by skill-neutral, as well as skill-biased shocks; hence stable ratios are theoretically consistent with a mix of skill-biased and skill-neutral shocks. Yet, numerical exercises confirm that wage rigidity in the face of skill-biased shocks probably did not explain much of the European unemployment experience.     

Idiosyncrasies of the Software Development Process and Their Relation to Software Patents: Theoretical Considerations and Empirical Evidence

In Europe, the future patenting of software-related inventions has been the subject of intensive discussions for some time, since there exists a strong dispute between the supporters of the U.S. practice of allowing patents in order to increase Europe's competitiveness and the opponents postulating negative impacts of patents on the software development process. This paper presents empirical results about the idiosyncrasies of the software development process and tests hypotheses on their impact on the likelihood of patents being obstacles for software dvelopment. The paper concludes with the identification of determinants for preferences concerning different possible patent regimes in the future.     

Genetic testing: affected parties and decision making

The network of issues around information obtained from genetic testing is wide and complex. While risk assessment, awareness and discussion are often public driven, and in many instances, including that of nuclear power, are allied with democratic principles, the case of gene technology and genetic testing appears to be different. The opportunity for risk assessment by gene testing is rejected by many, and this rejection is supported by the claim of the right not to know. This article discusses the background to this development, and argues that decisions that consider issues related to genetic testing should be taken with the participation of affected parties.     

Regulatory foresight: Methodologies and selected applications

This paper on regulatory foresight addresses approaches which allow future fields for regulatory action to be identified. We follow a rather wide perception of regulation and include standards and standardisation as elements of the regulatory framework. The paper presents three methodologies appropriate for performing regulatory foresight. First, an approach is presented which makes use of science and technology indicators and enables the identification of possible fields which may cause challenges for the regulatory framework and the regulatory bodies. Second, survey approaches are displayed which enable regulatory bodies to identify future needs for regulations. Finally, the usability of the Delphi methodology is discussed and results of a Delphi survey in the telecommunication area are presented. The paper concludes with a comparative analysis of the three methodological approaches regarding their effectiveness to conduct regulatory foresight.     

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.
