In recent work on non-cooperative network formation star-shaped networks play an important role. In a particular theoretical model of Bala and Goyal (2000) centersponsored stars are the only strict Nash networks. In testing this theoretical model Falk and Kosfeld (2003) do not find any experimental evidence that players select the centersponsored star. Based on a slight modification of Bala and Goyal's model we design a network formation experiment with varying link costs in which almost all groups not only reach a strict Nash network once but also switch strict Nash networks several times. The main innovation in our experiment is to use a continuous time framework which makes coordination on "stars" much easier than simultaneous strategy adaptation in discrete time.JEL classification: C72, C78, C92
