  1. The impact of human capital on regional labor productivity in Europe

    Fischer, Manfred M.; Bartkowska, Monika; Riedl, Aleksandra; Sardadvar, Sascha; Kunnert, Andrea
    This paper employs a spatial Durbin model for analyzing the impact of human capital on regional productivity using for 198 NUTS-2 European regions for the sample period from 1995 to 2004. The study provides evidence for the existence of spatial externalities and interactions of the sort as emphasized by new growth theory. To interpret results meaningfully, we calculate summary measures that account for the simultaneous feedback nature of the underlying model. By sampling from the parameter distribution we present measures of dispersion, revealing that it is relative regional advantages in human capital that matter most for productivity growth.

  2. Spatial econometric methods for modeling origin destination flows

    LeSage, James P.; Fischer, Manfred M.
    Spatial interaction models of the gravity type are used in conjunction with sample data on flows between origin and destination locations to analyse international and interregional trade, commodity, migration and commuting patterns. The focus is on the classical log-normal model version and spatial econometric extensions that have recently appeared in the literature. These new models replace the conventional assumption of independence between origin-destination flows with formal approaches that allow for spatial dependence in flow magnitudes. The paper also discusses problems that arise in applied practice when estimating (log-normal) spatial interaction models. (authors' abstract)

  3. Neoclassical theory versus new economic geography. Competing explanations of cross-regional variation in economic development

    Fingleton, Bernard; Fischer, Manfred M.
    This paper uses data for 255 NUTS-2 European regions over the period 1995-2003 to test the relative explanatory performance of two important rival theories seeking to explain variations in the level of economic development across regions, namely the neoclassical model originating from the work of Solow (1956) and the so-called Wage Equation, which is one of a set of simultaneous equations consistent with the short-run equilibrium of new economic geography (NEG) theory, as described by Fujita, Krugman and Venables (1999). The rivals are non-nested, so that testing is accomplished both by fitting the reduced form models individually and by simply combining the two rivals to create a...

  4. Implementing a Class of Permutation Tests: The coin Package

    Zeileis, Achim; Wiel, Mark A. van de; Hornik, Kurt; Hothorn, Torsten
    The R package coin implements a unified approach to permutation tests providing a huge class of independence tests for nominal, ordered, numeric, and censored data as well as multivariate data at mixed scales. Based on a rich and exible conceptual framework that embeds different permutation test procedures into a common theory, a computational framework is established in coin that likewise embeds the corresponding R functionality in a common S4 class structure with associated generic functions. As a consequence, the computational tools in coin inherit the exibility of the underlying theory and conditional inference functions for important special cases can be set up easily. Conditional versions of classical tests|such...

  6. Ein spieltheoretisches Arbeitsmarktmodell mit integrierter Lohn- und Suchdynamik

    Sigmund, Michael
    Diese Arbeit präsentiert ein neuartiges mikroökonomisch fundiertes Arbeitsmarktmodell in einem partiellen Gleichgewichtsmodell. Als Theoriegerüst wird der Rahmen wiederholter Spiele in Verbindung mit dem modernen mikroökonomischen Konzept der Bounded Rationality gewählt. Die entscheidenden Modellbausteine sind dynamische strategische Interaktion, die Implementierung von informationsbasierenden Marktfriktionen, Lernregeln, Heterogenität und durch Heterogenität induzierte Arbeitsteilmärkte. Im empirischen Teil dieser Arbeit wird die Bedeutung von Heterogenität im Kontext des Arbeitsmarktes herausgearbeitet. Dazu werden verschiedene Zeitreihen zu offenen Stellen, Arbeitslosigkeit und Erwerbstätigkeit herangezogen. Die empirischen Gegebenheiten zeigen, dass Heterogenität am Arbeitsmarkt eine zentrale Rolle spielt und daher auch theoretisch nicht vernachlässigt werden darf. Unter Berücksichtigung der empirischen Resultate...

  7. Pricing strategies in online & offline retailing

    Gruber, Gottfried
    The thesis deals with pricing strategies for multichannel retailers, especially traditional stores which additionally manage an online shop. The problem of integrating two sales channels and applying a well-suited pricing strategy is still an emergent question. This work develops a stochastic model to represent consumer behavior on pricing. On the one hand the model contains two probability functions which render consumers' reservation prices for each individual channel. On the other hand the stochastic model is based on numerous distributions which represent switching probabilities from and to each separate channel. The various distribution functions will be estimated from the results of...

  8. Die Lohnhöhe und Lohnstreuung im Nonprofit Sektor. Eine quantitative Analyse anhand österreichischer Arbeitnehmer-Arbeitgeber-Daten.

    Haider, Astrid
    Über die Lohnstruktur im Nonprofit Sektor ist wenig bekannt. Ziel der Dissertation ist es, Determinanten der Lohnhöhe und innerbetrieblichen Lohnstreuung in österreichischen Nonprofit Organisationen (NPO) näher zu erforschen. Besonderes Augenmerk wird auf die Eigenheiten einer NPO im Vergleich zu einem gewinnorientierten Unternehmen gelegt. Die Forschung beschäftigt sich daher mit der Frage, ob und wie ehrenamtliche Mitarbeiter/-innen, Spenden und Subventionen die Lohnhöhe und die innerbetriebliche Lohnstreuung von bezahlten Arbeitnehmer/-innen einer NPO beeinflussen. Diese Variablen werden zusätzlich zu anderen Determinanten auf Individual- und Organisationsebene in die Lohngleichungen inkludiert und stellen eine Erweiterung bekannter Modelle dar. Zur empirischen Überprüfung werden österreichische Arbeitnehmer-Arbeitgeberdaten herangezogen,...
