Abstract: Business Research als die wissenschaftliche Zeitschrift des Verbandes der Hochschullehrer für Betriebswirtschaft hat sich zum Ziel gesetzt, neben aktuellen Forschungsergebnissen aus allen Bereichen der Betriebswirtschaft ihren Lesern den inhaltlichen und methodischen Stand der Technik in einzelnen Teilbereichen vorzustellen. Diese Veranstaltung stellt den Auftakt zu einer regelmäßigen Reihe von Vorträgen und Übersichtsartikeln dar.

Testing u-shaped, inverted u-shaped or other nonlinear relationships in business

Research typically tests for linear relationships between success variables and its drivers. In many instances, in particular in marketing, relationships are rather nonlinear. This is mostly investigated by testing for quadratic effects. Seldomly, rival relationships of just convex or concave or more complex relationships are tested. This paper shows how to proceed to find the true nonlinear relationship and to test for it. It includes discussions of different flexible nonlinear functions as well methods such as spline functions, Kernel regression, local polynomial smoothing, moving averages, quantile regression.

Passenger Transportation in Rural Areas

In rural areas the public transportation means almost disappear. Regular public bus or train connections are drastically reduced. Nevertheless, there is a need in public transportation services especially for the younger (e.g. school children) and the older generation (e.g. retired people). The population in rural areas has to be transported to doctors, supermarkets, public authorities, schools. In this talk new concepts in designing and operating demand responsive transportation networks in rural areas are presented. State-of-the-art concepts for flexible bus services, school busses, dial-a-ride, car pooling and multi-modal variants of these concepts are presented.
