  1. Centrality and Pricing in Spatially Differentiated Markets: The Case of Gasoline

    Weiss, Christoph; Pennerstorfer, Dieter; Firgo, Matthias
    We highlight the importance of "centrality" for pricing. Firms characterized by a more central position in a spatial network are more powerful in terms of having a stronger impact on their competitors' prices and on equilibrium prices. These propositions are derived from a simple theoretical model and investigated empirically for the retail gasoline market of Vienna, Austria. We compute a measure of network centrality based on the locations of gasoline stations in the road network. Results from a spatial autoregressive model show that prices of gasoline stations are more strongly correlated with prices of central competitors.

  2. Sequential and parallel large neighborhood search algorithms for the periodic location routing problem

    Hemmelmayr, Vera
    We propose a large neighborhood search (LNS) algorithm to solve the periodic location routing problem (PLRP). The PLRP combines location and routing decisions over a planning horizon in which customers require visits according to a given frequency and the specific visit days can be chosen. We use parallelization strategies that can exploit the availability of multiple processors. The computational results show that the algorithms obtain better results than previous solution methods on a set of standard benchmark instances from the literature.

  3. Reduction of Working Time in Austria. A Mixed Methods Study Relating a New Work Time Policy to Employee Preferences

    Gerold, Stefanie; Nocker, Matthias
    This mixed-methods study examines factors determining employees' desire to reduce worktime. The results of a binary logit regression model, based on data from the Austrian Microcencus 2012, suggest that employees who prefer shorter weekly working hours are older, higher educated and work longer hours in white-collar positions, compared to those who do not wish to change their hours. Gender differences are greatest in terms of household and family characteristics, supporting the 'male breadwinner & part-time' model. Qualitative interviews have been conducted among employees who had the possibility to choose between a pay increase and equivalent leisure time via a new...

  4. Investor borrowing heterogeneity in a Kiyotaki-Moore style macro model

    Punzi, Maria Teresa; Rabitsch, Katrin
    We introduce heterogeneity in investors' ability to borrow from collateral in a Kiyotaki-Moore style macro model, calibrated to the quintiles of the leverage-ratio distribution of US non-financial firms. Financial amplification intensifies, because of stronger asset price reactions of highly levered investors. (authors' abstract)

  5. The Nationalökonomische Gesellschaft (Austrian Economic Association, NOeG) in the Interwar Period and Beyond

    Klausinger, Hansjörg
    The Nationalökonomische Gesellschaft (Austrian Economic Association, NOeG) provides a prominent example of the Viennese economic circles that more than academic economics dominated scientific discourse in the interwar years. For the first time this paper gives a thorough account of its history, from its foundation 1918 until the demise of its long-time president, Hans Mayer, 1955, based on official documents and archival material. The topics treated include its predecessor and rival, the Gesellschaft österreichischer Volkswirte, the foundation 1918 soon to be followed by years of inactivity, the relaunch by Mayer and Mises, the survival under the NS-regime and the expulsion of...
