This editorial publication offers twelve contributions from the German “Wirtschaftsinformatik”
that exemplify the modern process of theory-guided modeling and empiricism which enhances current techniques. It summarizes contemporary examine which has been provided at significant foreign and nationwide meetings so that it will show the turning out to be value of this stream
of research.

0 . , Weitzel et al. (2006) for a similar approach). For simplification, it is assumed that only positive base values for the information and integration costs can occur. Accordingly, the normal distribution is “cut” at the zero point. This results in a truncated normal distribution (Johnson and Thomopoulos 2002), and for the adjusted expected value Pkorr cij holds (Arzideh 2008): § Pc · ¸ © Vc ¹ Pkorr cij : Pc V c § P · 1 ) ¨ c ¸ © Vc ¹ I ¨ [10] adjusting term Here, I denotes the density function and ) denotes the cumulative distribution function of the standard normal distribution.
Of “complete standardization”) in comparison to a potential solution in which for each edge, the maximum possible information and integration costs arise. With deg , the average degree, the number of edges of the graph, can be calculated and P IICB can be defined as: P IICB : Pkorr cij O deg N 2 [18] expected ed difference of information number of edges and integration costs per edge 12 13 Based on the assumptions (cf. [11]), the following holds: cijAB cijBA and cijAA cijBB and also cijBA cijBB cij O .
In this context, we consider the interaction between the platform and complementary products, as well as the information relationships between complementary components. 3 Katz and Shapiro (1985) define the concept of network effects as follows: “The utility that a given user derives from the good depends upon the number of other users who are in the same ‘network’ as is he or she” (Katz and Shapiro 1985; Liebowitz and Margolis 1994). Several articles provide a sound overview of the network effect theory (David and Greenstein 1990; Gandal 2002; Koski and Kretschmer 2004; Matutes and Regibeau 1996; Weitzel et al.
