This paper studies optimal sport league size. League expansion lowers average player quality, reducing fans' utility in inframarginal locations, while fan utility in new locations rises. Welfare analyses of such expansions must compare these two effects. Using a model where fan demand depends on...

The Global Terrorism Database contains many active and inactive terrorist groups. Whether one considers their size to be measured in terms of grassroots support or number of members (individual terrorists), the defining characteristic of the terrorist groups contained in the GTD is smallness....

Mit mehr als 6.000 Unternehmen kann die Trinkwasserversorgung Deutschlands im internationalen Vergleich als höchst fragmentiert angesehen werden. Während die Trinkwasserversorgung in zahlreichen Ländern durch eine ähnliche Fragmentierung gekennzeichnet ist, gibt es aber auch Beispiele...

Das Thema Existenzgründung ist in der Öffentlichkeit seit einigen Jahren sehr populär geworden. Doch welche Faktoren beeinflussen die Entwicklungschancen neu gegründeter Betriebe wirklich? Markus Heckmann hat in seiner Dissertation die Angaben von Existenzgründern ausgewertet, die im Zuge...

Um die Mitte des 19. Jahrhunderts verfügten die deutschen Bergleute mit den Knappschaftsvereinen über ein eigenes institutionalisiertes Sozialversicherungssystem, dessen historische Wurzeln bis zurück ins Mittelalter reichen und das insbesondere auch beispielgebend für die Ausgestaltung der...

We model a firm in an institutional market setting, consisting of a production technology and its governance. The governance consists of a hierarchical firm structure, a cost efficiency parameter,and an internal pay system. The depth of the firm is determined by profit maximization under the...

In this article, we simulate the concentration process within the German dairy sector employing a sector?wide optimization model. As a result, we get cost minimizing structures of the dairy sector for various time horizons depending on varying levels of transportation costs. We show that the...

This paper models the trade-off between production and appropriation in the presence of simultaneous inter- and intra-group conflicts. The model exhibits a 'group cohesion effect': if the contest between the groups becomes more decisive, or contractual incompleteness between groups becomes more...
