Linkage lock-in and regional economic development: the case of the Øresund medi-tech plastics industry

This paper examines the role of interfirm linkages in influencing the dynamics of regional economic development. Developing a conceptual framework, we claim that switching costs (real or perceived) can lock firms into existing linkages with the potential effect of impeding regional economic development. A main argument is that in dynamic and competitive environments a class of switching costs, learning opportunity costs, might arise out of the relative importance of learning and innovation. We apply our framework to understand what goes on in the Øresund medi-tech plastics industry, taking as a starting point the lack of cross-border linkage participation in this industry. Through a case study research design we obtain evidence about the characteristics and dynamics of linkage lock-in and switching costs in this particular context and explain that learning opportunity costs prevail and make increased linkage participation across Øresund tardy. Promising future research arising from the present study includes enquiry into dissimilar industries, the possible intermediating role of third parties and the complementarities of the Danish and Swedish areas with a focus on the potential of cross-border regional specialization. All this would potentially add to a more complete picture of the notion of switching costs.     

Nature or nurture: What determines investor behavior?

Using data on identical and fraternal twins’ complete financial portfolios, we decompose the cross-sectional variation in investor behavior. We find that a genetic factor explains about one-third of the variance in stock market participation and asset allocation. Family environment has an effect on the behavior of young individuals, but this effect is not long-lasting and disappears as an individual gains experience. Frequent contact among twins results in similar investment behavior beyond a genetic factor. Twins who grew up in different environments still display similar investment behavior. Our interpretation of a genetic component of the decision to invest in the stock market is that there are innate differences in factors affecting effective stock market participation costs. We attribute the genetic component of asset allocation—the relative amount invested in equities and the portfolio volatility—to genetic variation in risk preferences.     

Renewable Energy Policy Instruments and Market Power

Markets for green certificates allow generators with market power to squeeze the margins of their competitors, as a generator that is vertically integrated into network activities might do. We analyze this issue in a stylized electricity industry in which a dominant producer of both conventional and renewable energy is facing a competitive fringe of renewable‐energy producers. We demonstrate that whether or not a dominant firm is vertically integrated into network activities, it can disadvantage the fringe producers by distorting certificates prices, thereby inducing cost inefficiency in the generation of renewable energy. We compare green certificates to a system of feed‐in tariffs, where a similar margin squeeze is not possible.     

How do lean management organizations behave regarding training and development?

This paper analyses the role of training and development in lean management organizations. The hypothesis is that organizations characterized by lean management have a distinctive profile in terms of training and development. Specifically, it is hypothesized that lean organizations have the following features to a higher extent than non-lean organizations:

? employee involvement in training and development

? use of work groups for quality, product development and task flexibility

? attribution of importance to training in quality, customer orientation and people management

? line management responsibility for training and development of the employees

? use of job enlargement

? information of employees about management decisions

? use of team briefings and quality circles.

The analysis shows that it is possible to identify a relationship between lean management and training and development, although the statistical results could have been more significant. It is also discussed in the paper to what extent country-specific variables dominate (or are dominated by) company-specific characteristics. The general finding is that company-specific impact seems to be stronger than country-specific variables.

In general, it can be said that the lean management pattern as a company-specific variable is characteristic for most countries analysed (although to a varying degree). It is, however, sometimes confounded by country-specific variables. For instance, Turkey does not follow the general pattern, and the hypothesis can be supported only in selected minor areas. Hence, in this case country-specific variables outweigh company-specific variables. In most other countries, this is not the case.     

Special and differential treatment in the WTO agricultural negotiations: Analysis and policy recommendation

The on-going Doha Development Round under the World Trade Organization (WTO) has its main focus on development. This is due to the widespread disappointment with the results from the former Uruguay Round Agreement. Developing countries have not reaped the benefits of free trade. For this current Round to be a success, developing countries have to be more integrated in the multilateral trading system. One of the means of integrating is Special and Differential Treatment (SDT). SDT is a deviation from the basic principle of Most Favoured Nation, positing that developing countries can have more flexibility than others. This article investigates the positions on SDT made by WTO members. The analysis gives some insights into the negotiations. First, the analysis reveals the fact that the positions of WTO members are relatively close to each other. This could indicate that countries in fact agree or that sensitive areas are maintained as yet unaffected. Second, being able to sustain a certain level of tariff rates attracts most interest from developing countries. Third, higher income developing countries want to retain their right to support domestic producers. Finally, the article identifies the July Package right in the middle of the positions which indicate a future agreement.     

Why Agency Costs Explain Diversification Discounts

We study diversificsation within the real estate industry because of its relative transparency: portfolio management of assets with well-defined market prices. Diversification is over property types and geographical regions. The major cause of the diversification discount is not diversification per se but anticipated costs due to rent dissipation in future diversifying acquisitions. Firms expected to pursue nonfocusing strategies do indeed diversify more, are valued ex ante at a 20% discount over firms anticipated to follow a focusing strategy, are predominantly privately controlled and use dual-class shares extensively. The ex ante diversification discount is, therefore, a measure of agency costs.     

The constitutive element of probabilistic agency in risk: a semantic analysis of risk,danger, chance,and hazard

Defining central concepts with accuracy is crucial to any scientific discipline. A recent debate over risk definitions in this journal illustrates the far reaching consequences of divergent definitions. Aven and Renn define risk as a social construct while Rosa defines risk as an ontological fact. Both claim that their definition reflects the common usage of the word risk. Through a semantic analysis this paper points to a constitutive element of what is termed probabilistic agency in the risk concept. In this respect, risk is distinct from danger, and because Rosa’s main argument is based on the apparent synonymy between risk and danger, the premises for his risk ontology are not valid. The paper furthermore argues that Aven and Renn’s attempt to bridge between epistemology and ontology is based on a distinction between a conceptual level of risk and its practical application which is impossible to uphold if a risk definition is to be in accordance with the ordinary usage of the word. The paper concludes by arguing that risks are only real within a subjective ontology.     

Consumption taxes in monopolistic competition: a comment

We show that an ad valorem tax is better than an equal-revenue unit tax when consumers spend some fixed proportion of income on taxed goods, when firms use constant mark-up pricing, and entry and exit drive per-firm profit to zero. These key assumptions implies that ad valorem taxes are superior in oligopoly as well as monopolistic competition, showing that earlier results on taxes in monopolistic competition (Schröder in J Econ 83(3):281–292, 2004) are not due to the mode of competition, but rather are due to the functional forms used.
