  3. Firm Strategies and Restructuring in a Globalising Economy

    Tödtling, Franz
    The past decades have seen severe sectoral and spatial shifts of industry. By some scholars these were interpreted as "break-down" of traditional core - periphery structures, others saw the emergence of a new regional growth model, such as the industrial district or the networked region. Underlying these phenomena are strategic and organisational responses of firms to a rapidly changing environment. Since the 1980s there was a certain catching up of some of the newly industrialising countries as well as an increasing interdependence between the countries of the "Triad" (Europe, USA, Japan) leading to a reinforced competition in a variety of industries....

  6. The Asymptotic Loss of Information for Grouped Data

    Felsenstein, Klaus; Pötzelberger, Klaus
    We study the loss of information (measured in terms of the Kullback- Leibler distance) caused by observing "grouped" data (observing only a discretized version of a continuous random variable). We analyse the asymptotical behaviour of the loss of information as the partition becomes finer. In the case of a univariate observation, we compute the optimal rate of convergence and characterize asymptotically optimal partitions (into intervals). In the multivariate case we derive the asymptotically optimal regular sequences of partitions. Forthermore, we compute the asymptotically optimal transformation of the data, when a sequence of partitions is given. Examples demonstrate the efficiency of...

  7. Comparing Local Fitting to Other Automatic Smoothers

    Maderbacher, Michael; Müller, Werner
    In a public service enterprise by Breiman and Peters (1991) various automatic smoothers, such as the supersmoother (SSMU), cross-validated smoothing splines (BART), delete-knot regression splines (DKS) and the cross-validated kernel smooth (KERNEL) were compared by simulation on a variety of sample sizes, noise levels and functions. The intention was to give practitioners guidelines when to use which type of smoother. The given work completes those simulations by including the increasingly popular local fitting approach, that was introduced to the statistical literature by Cleveland (1979). Fedorov et al. (1993) have modified the technique in order to take account possible misspecification bias,...

  8. Finite de Finetti-Type Results as Approximation Results by the Expectation of Sufficient Statistics

    Pötzelberger, Klaus
    We show that finite de Finetti-type results may be viewed as results on the approximation of certain continuous functions of a parameter by a sequence of positive operators (Ln) . For distribtions that depend on a finite-dimensional statistic (Tn) only, Ln is the expectation operator of (Tn) under the extremal infinite exchangeable distributions. The rate of approximation of finite exchangeable distributions by mixtures of marginals of infinite exchangeable distributions is the rate of approximation of a single function of the parameter, namely the second indefinite integral of the Fisher information. Our results include a major part of what is known...

  9. A Universal Generator for Bivariate Log-Concave Distributions

    Hörmann, Wolfgang
    Different universal (also called automatic or black-box) methods have been suggested to sample from univariate log-concave distributions. The description of a universal generator for bivariate distributions has not been published up to now. The new algorithm for bivariate log-concave distributions is based on the method of transformed density rejection. In order to construct a hat function for a rejection algorithm the bivariate density is transformed by the logarithm into a concave function. Then it is possible to construct a dominating function by taking the minimum of several tangent planes which are by exponentiation transformed back into the original scale. The...

  10. Asymptotic Efficiency of Estimates for Models with Incidental Nuisance Parameters

    Strasser, Helmut
    In this paper we show that the well­known asymptotic efficiency bounds for full mixture models remain valid if individual sequences of nuisance parameters are considered. This is made precise both for some classes of random (i.i.d.) and non­random nuisance parameters. For the random case it is shown that superefficiency of the kind given by an example of Pfanzagl (1993) can happen only with low probability. The non-random case deals with permutation invariant estimators under one­dimensional nuisance parameters. It is shown that the efficiency bounds remain valid for individual non­random arrays of nuisance parameters whose empirical process, if it is centered...

  11. Reducing the greenhouse effect in Austria. A general equilibrium evaluation of CO2-policy-options.

    Breuss, Fritz; Steininger, Karl
    The model presented in this paper allows realistic simulations for CO2 policy options for Austria. It is based on a static perfect competition CGE model, calibrated for 1990 Austrian data. Special attention has been given to the implementation of the link of economic and energy data. As a new feature the negative consequences of the CO2 taxation as far as competitiveness in a small open economy is concerned are tried to be mitigated by compensation via wage tax rebates. This is achieved by a sectorally differentiated compensation scheme. As a result competitiveness in the energy intensive sectors can be established...

  12. Can EU's cohesion policy achieve convergence?

    Tondl, Gabriele
    In this paper I would like to raise the question at which extent the Union's cohesion policy can promote convergence within the Union. I will discuss major aspects of an analysis on the justification and of the design of the Union's cohesion policy. For this purpose recent empirical data and policies will be investigated. The paper will focus on the weaker Member States of the European Union. (author's abstract)

  13. Nationale bzw. gesamtwirtschaftliche Effekte von Beihilfen. Insbesondere Exportbeihilfen.

    Gumpold, Jutta
    Es wurde versucht, unter Einbeziehung der zahlreichen, divergierenden Effekte von Beihilfen zu zeigen, daß diese in einem System der vollständigen Konkurrenz den effizienten Ablauf der Wirtschaft stören. Beihilfen stellen ein Mittel der Wirtschaftspolitik dar, das die Mechanismen der freien Marktwirtschaft hemmt und grundsätzlich zu Wettbewerbsverzerrungen führt. Subventionsmaßnahmen sind geeignet die optimale Allokation der Produktionsfaktoren zu verhindern und Wirtschaftswachstum und Beschäftigung zu senken ... Da es keine allgemeingültige Regel zur Bestimmung eines optimalen Beihilfenniveaus gibt und die wettbewerbsverzerrenden Wirkungen von Subventionen die möglichen positiven Effekte weitaus übertreffen, wird hier die Meinung vertreten, daß eine äußerst restriktive Beihilfenpolitik, die nur in ganz...

  14. Beschäftigungseffekte des österreichischen Osthandels. 1989 - 1994.

    Altzinger, Wilfried
    Die sogenannte "Ostöffnung" des Jahres 1989 hat die österreichische Wirtschaft durch seine unmittelbare Nachbarschaft mit den entwickeltsten Transformationsstaaten sehr unmittelbar beeinflußt. Neben einem starken Anstieg des österreichischen Investitionsengagements in den CEEC-6 (Polen, Ungarn, Tschechien, Slowakei, Slowenien, Kroatien) sowie einer im Vergleich zu anderen OECD-Staaten überdurchschnittlichen Betroffenheit von Migrationströmen hatte die Ostöffnung vor allem äußerst positive Konsequenzen für die österreichische Handelsentwicklung mit Mittel- und Osteuropa. Die völlige Umorientierung der wirtschaftlichen Beziehungen hin zu den westlichen Industrienationen war mit stark positiven Effekten für die österreichische Handelsbilanz verbunden.
