Clements (2004) makes the following two claims: (i) unlike direct network effects, increases in the size of the market do not, in the case of indirect network effects, make standardization more likely, but (ii) indirect network effects are associated with excessive standardization. We show in...

The conventional wisdom is that indirect network effects, unlike direct network effects, do not give rise to externalities. In this Paper we show that under very general conditions, indirect network effects lead to adoption externalities. In particular we show that in markets where consumption...

Can indirect network effects lead to adoption externalities? If so, when? We show that in markets where consumption benefits arise from hardware/software systems, adoption externalities will occur when there are (i) increasing returns to scale in the production of software, (ii) free entry in...

We address the possibility of foreclosure in markets where the final good consists of a system composed of a hardware good and complementary software and the value of the system depends on the availability of software. Foreclosure occurs when a hardware firm merges with a software firm and the...

In this paper we address the possibility of horizontal foreclosure in markets for complementary services (software) where the consumption value of durables (hardware) depends on the availability of software. Horizontal foreclosure occurs when a hardware firm merges with a software firm and the...
