Home Papers on the channel competition between magazines and their online companions Arbeiten zur Konkurrenz zwischen Zeitschriften und deren Online-Ausgabe Magazines and their Companion Websites: Competing Outlet Channels? Paper download Abstract: This paper provides empirical evidence for the widespread belief that a magazine's companion website induces channel competition on its print version. The analysis is based on aggregated quarterly magazine-specific data on circulation, a broad variety of magazine characteristics, consumer characteristics and information on a magazine's website presence. The data spans the period I/1996 to IV/2004. Nested logit-type models of demand for differentiated products are used in the empirical analysis. A main result of this paper is that magazines that run an online companion on average loose 4.2 percent of their potential consumers. This effect varies substantially across different consumer age groups and across time.

(with Hans Christian Kongsted) Paper download Abstract: We analyze the extent to which visits to a magazine's companion website affects total circulation, subscription, kiosk sales and foreign sales using Granger non-causality tests on the basis of monthly data for the German magazine market spanning the period January 1998 to September 2005. We find evidence for positive effects of website visits on magazine subscription but negative effects on magazine kiosk sales. Contrary to the widespread belief that the Internet will cannibalize print media markets, our results do not, however, provide evidence for website visits adversely affecting total circulation.
