Developing integration in a local industrial ecosystem – an explorative approach

The objective of this study is to develop and evaluate an approach for initiating development of a local industrial symbiosis network. By maintaining the broad perspective of industrial symbiosis, which includes both material and energy flow analysis, and also taking into account the internal energy use and possibilities for energy savings, we aim to achieve a better system view that avoids both sub‐optimizations and unhealthy dependencies. The approach is applied to a case based on the cooperation between the forest industry, municipality and energy service company in a small town in southern Sweden. Several possibilities for improving material and energy use by increasing integration were identified. It was concluded that it is important to have a genuine knowledge of the system studied and close contact with the actors involved, since a simple analysis of energy and material flows is not sufficient to decide which solutions might be more advantageous. It is also important to have a flexible system boundary looking at the system from different perspectives and at different levels to find the best uses for existing energy and material streams.

The Relative Importance of Actual and Potential Competition: Empirical Evidence From the Pharmaceuticals Market

We study actual and potential competition and other factors that determine price paths of brand-name drugs in the Swedish pharmaceuticals market. The results indicate that the price of the incumbent product is lowered by potential competition, entry of (additional) generics, and the introduction of a so-called reference-price system. We also identify a 'ratchet' effect, through which price regulation makes entry-deterring limit-pricing credible.     

Economic discrimination in a two-good model

Conclusions The main conclusion of this study is that in the general case we cannot make any predictions regarding the effects of discrimination on the welfare of whites or blacks. To reach definite results special assumptions have to be made, and even then much depends on in terms of which good the effects are measured.Joseph E. Stiglitz has criticized the trade approach to discrimination on the grounds that once the step is taken from the simple Beckerian one-good model to the full-fledged two-by-two-by-two framework used in international trade theory this approach can no longer explainwage differences, since the factor equalization theorem will apply, at least as long as the two groups are not totally specialized in production⁸. This criticism can be extended in the light of the results of the present work. We have in the foregoing seen how even in a model that assumes total specialization in production we cannot reach any clear-cut conclusions regarding under which circumstances it pays for the majority group to discriminate against the minority. Maximization of majority welfare by means of economic discrimination simply requires too much information, at least when the trade approach is used. Other theories are likely to yield better explanations regarding the causes of discrimination, and future research is likely to become more fruitful if attention is concentrated more on alternative approaches.The research was financially supported by the Swedish Council for Social Science Research (Statens råd för samhällsforskning).

Kunden- oder Markenorientierung – Zwei Seiten einer Medaille oder alternative Routen?

Kundenorientierung bildet seit langem den Kern eines modernen Marketingverst?ndnisses. Allerdings ist fraglich, ob es nicht Alternativen zu einer Kundenorientierung gibt. Dieser Artikel pr?sentiert mit der Markenorientierung eine solche alternative strategische Orientierung und diskutiert die Unterschiede zwischen Kunden- und Markenorientierung auf einer theoretischen, kulturellen, verhaltens- und controllingorientierten Ebene.     

The distribution of abilities and the progressive income tax

This paper develops a model of endogenous labor supply, where agents are uncertain about their future wages. Assuming risk aversion, some redistributive taxation is thus warranted. It is shown that, for a particular parameterization of the tax system, an optimally progressive income tax exists. Comparative ststics analysis demonstrates how this tax system is effected by changes in the wage distribution. The paper ends with a discussion of whether an optimally progressive income tax can be politically sustained. It is shown that generally this is not the case in a political system with majority voting.     

Comparing Merger Policies in the European Union and the United States

We collect a sample of EU and US merger investigations, estimate models of the regulatory decisions, and use the models to compare merger policies. Our approach allows us to decompose observed differences into policy effects and case-mix effects. Focusing on dominance mergers, we find that the EU is tougher than the US on average, in particular for mergers resulting in moderate market shares. However, the US appears to be more aggressive for coordinated interaction and non-dominance unilateral effects cases. Overall, our analysis detects substantial differences in policies, but it does not classify one regime as being more aggressive than the other.     

Income from Work Among Immigrants in Sweden

This paper uses a two-step Heckman approach to investigate to what extent there are differences in income from work between immigrants and natives in Sweden. Contrary to previous studies this study takes the selection effect, i.e. the probability of having an income from work, into account when calculating the effect on income from work of a change in any of the explanatory variables. Our study shows that when the selection effect is taken into account, the differences in income from work between immigrants and natives are smaller than when the selection effect is not considered. We find that immigrants have a lower income from work than the native population when we control for variables such as schooling, experience, civil status and region of residence. Furthermore, immigrant cohorts with a recent year of immigration have a considerably lower income from work than earlier immigrant cohorts.     

Book review

Although best practice transfer methodologies have become an increasingly common instrument in enterprise policy development, barriers to the exchange and dissemination of knowledge may limit their effectiveness. Using START, an EC-funded network of regional agencies, as a case this paper explores the dynamics of experience exchange in regional enterprise policy. Working closely with the START partnership, the authors developed a detailed account of how the network communicated and disseminated cases and instances of regional start-up policy and practice between themselves. Partners in START were more likely to adapt abstracted principles, concepts and ideas that informed changes to their own practices than to adopt specific initiatives from other regions. This suggests a need to re-focus best practice transfer methodologies away from the transplantation of established practices towards encouraging interactive and collaborative learning based on the sharing of experience.
