    Description / Table of Contents: Zusammenfassung In der Arbeit werden die Standorte von Duopolisten in einem Baum untersucht. Unter der Annahme festgesetzter Preise werden notwendige und hinreichende Bedingungen für Nash Gleichgewichte für Standorte auf Bäumen hergeleitet. Unter Verwendung dieser Bedingungen wird dann gezeigt, daß — angenommen Nash Gleichgewichte existieren — diese in einem wiederholt angewandten sequentiellen Standortfindungsprozeß, in dem beide Duopolisten als Zielfunktion kurzfristige Gewinnmaximierung haben, auch erreicht werden.
    Notes: Abstract This paper examines the location of duopolists on a tree. Given parametric prices, we first delineate necessary and sufficient conditions for locational Nash equilibria on trees. Given these conditions, we then show that Nash equilibria, provided they exist, can be reached in a repeated sequential relocation process in which both facilities follow short-term profit maximization objectives.

    Money demand stability: Evidence from Spain (1998)
    Springer
    Empirical economics 23 (1998), S. 387-400 
    Details
    ISSN: 1435-8921
    Keywords: Key words: Money demand ; cointegration ; stability ; regime shift ; JEL classification: E41 ; C22
    Source: Springer Online Journal Archives 1860-2000
    Topics: Economics
    Notes: Abstract. Using several tests for structural stability in regressions with I(1) variables and for the existence of cointegration in models with regime shifts, the empirical evidence on the existence of a structural break in the Spanish long-run demand for broad money (ALP2) is analysed.  The results indicate that shifts affecting the demand for ALP2 in recent years have substantially altered its long-run properties. As to the cause of this structural break, emphasis is placed on the role played by the increasing openness of the Spanish financial system to international markets as obstacles to free capital movements have progressively disappeared.

    Sensitivity and Stability of the Classifications of Returns to Scale in Data Envelopment Analysis (1999)
    Springer
    Journal of productivity analysis 12 (1999), S. 55-75 
    Details
    ISSN: 1573-0441
    Keywords: Data envelopment analysis (DEA) ; returns to scale (RTS) ; sensitivity ; stability
    Source: Springer Online Journal Archives 1860-2000
    Topics: Economics
    Notes: Abstract Sensitivity of the returns to scale (RTS) classifications in data envelopment analysis is studied by means of linear programming problems. The stability region for an observation preserving its current RTS classification (constant, increasing or decreasing returns to scale) can be easily investigated by the optimal values to a set of particular DEA-type formulations. Necessary and sufficient conditions are determined for preserving the RTS classifications when input or output data perturbations are non-proportional. It is shown that the sensitivity analysis method under proportional data perturbations can also be used to estimate the RTS classifications and discover the identical RTS regions yielded by the input-based and the output-based DEA methods. Thus, our approach provides information on both the RTS classifications and the stability of the classifications. This sensitivity analysis method can easily be applied via existing DEA codes.

    Property Rights and Biodiversity (1998)
    Springer
    European journal of law and economics 6 (1998), S. 285-304 
    Details
    ISSN: 1572-9990
    Keywords: Property rights ; biodiversity ; bioprospecting ; and Coase-theorem
    Source: Springer Online Journal Archives 1860-2000
    Topics: Law , Economics
    Notes: Abstract This essay deals with the allocation of genetic resources with regard to property-rights theory. In addition to this, different arrangements of property rights will be examined as to their allocation and distribution effects. The result will show that property rights on biological diversity can only cover patrimonial rights which contain the right to use the resource but not to destroy it. Bioprospecting conventions, such as the well known Merck-INBio agreement, will be examined as mechanisms to establish property rights in terms of biological diversity. Moreover, the identification of these agreements will be critically questioned for their applicability as a form of the Coase-theorem.

    Resilience in the Dynamics of Economy-Environment Systems (1998)
    Springer
    Environmental and resource economics 11 (1998), S. 503-520 
    Details
    ISSN: 1573-1502
    Keywords: biodiversity ; dynamics ; resilience ; stability
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering , Economics
    Notes: Abstract The ecological concept of resilience has begun to inform analysis of change in economy-environment systems. The linkages between resilience and the stability of dynamical systems are discussed, along with its role in understanding of the evolution of such systems. Particular linkages discussed include those between resilience, biodiversity and the sustainability of alternative states. Recent developments in modelling the resilience of joint economy-environment systems suggest the advantages of analysing change in the system as a Markov process, the transition probabilities between states offering a natural measure of the resilience of the system in such states. It is argued that this ‘emergent property’ of the collaboration between ecology and economics has far-reaching implications for the way we think about, model and manage the environmental sustainability of economic development.

    Role of the Minimal State Variable Criterion in Rational Expectations Models (1999)
    Springer
    International tax and public finance 6 (1999), S. 621-639 
    Details
    ISSN: 1573-6970
    Keywords: expectations ; bubbles ; uniqueness ; stability ; state variables ; multiplicity
    Source: Springer Online Journal Archives 1860-2000
    Topics: Economics
    Notes: Abstract This paper concerns the minimal-state-variable (MSV) criterion for selection among solutions in rational expectationsmodels that feature a multiplicity of paths that satisfy all of the model's conditions. It compares the MSVcriterion with others, including the widely used saddle-path (dynamic stability) criterion. It is emphasized that theMSV criterion can be viewed as a scientifically useful classification scheme that delineates the unique solutionthat is free of bubble components. In the process of demonstrating uniqueness for a broad class of linear models,the paper exposits a convenient computational procedure. Applications to current issues are outlined.

    Land use, biodiversity, and sustainability (1999)
    Springer
    Journal of economics 70 (1999), S. 1-16 
    Details
    ISSN: 1617-7134
    Keywords: agriculture ; biodiversity ; forests ; land use ; sustainable development ; Q23 ; Q24
    Source: Springer Online Journal Archives 1860-2000
    Topics: Economics
    Notes: Abstract We focus on the effects of deforestation for agricultural purposes on biodiversity. This topic has been dealt with in the recent literature where “forested land” and “biodiversity” are treated as synonyms. In contrast to that, this paper distinguishes between “forested land” and “forest” itself, the latter being interpreted as a measure of biodiversity. The regenerative capacity of forests is modeled as a function of the own stock and of the habitat size. In particular, the threat of a given minimum viable population to be achieved in the course of the reduction of habitats is taken into account. The corresponding structure of a sustainability indicator is elaborated.

    Portfolio optimization via stochastic programming: Methods of output analysis (1999)
    Springer
    Mathematical methods of operations research 50 (1999), S. 245-270 
    Details
    ISSN: 1432-5217
    Keywords: Key words: Portfolio optimization ; stochastic programming ; stability ; postoptimality ; worst-case analysis
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mathematics , Economics
    Notes: Abstract. Solutions of portfolio optimization problems are often influenced by errors or misspecifications due to approximation, estimation and incomplete information. Selected methods for analysis of results obtained by solving stochastic programs are presented and their scope illustrated on generic examples – the Markowitz model, a multiperiod bond portfolio management problem and a general strategic investment problem. The approaches are based on asymptotic and robust statistics, on the moment problem and on results of parametric optimization.

    Incremental Cost in the Convention on Biological Diversity (1998)
    Springer
    Environmental and resource economics 11 (1998), S. 217-241 
    Details
    ISSN: 1573-1502
    Keywords: environmental and natural resource economics ; global environmental problems ; transboundary externalities ; biodiversity ; incremental cost
    Source: Springer Online Journal Archives 1860-2000

    Notes: Abstract The Convention on Biological Diversity stipulates the principle of incremental cost for the international financing of biodiversity conservation. The international debate about the exact meaning of the concept and about its practical application focuses on the issues of baseline determination and treatment of incremental domestic benefits. This paper uses some standard tools of partial equilibrium demand analysis to illustrate theoretical solutions to the indeterminacy of the Convention. The allocation of resources resulting from an incremental cost scheme is compared with a 'domestic optimum', and with a hypothetical 'global optimum'. Regarding the behaviour of the country hosting biodiversity, a distinction is proposed between 'quantity-' and 'transfer-' taking behaviour. The issue of price distortions in the baseline is also addressed. It is shown that both the host country (H) and the Rest of the World (ROW) will have incentives for agreeing on a transfer of resources that entails only partial deduction of domestic incremental benefits. This transfer, despite failing to reach the utilitarian global optimum, still represents a Pareto improvement over the pre-convention status quo. By imposing a particular multiplicative functional form on the utility of both host and ROW, additional results can be obtained. In particular, the optimal transfer implies a clawback factor decreasing with relative income differentials, and incremental cost financing dominates the domestic optimum even when price distortions are present in the host country. If removal of price distortions is a precondition for incremental cost funding, the analysis illustrates the magnitude of incentives necessary for the host to give up the distorted baseline.
