This paper analyzes the effects of one-way compatibility on technology adoption in a market that is characterized by a free-entry condition on the software side. We show that hardware-backward compatibility increases a new-generation hardware firm's profit; the effects of software-backward compatibility on the hardware firm's profits depend on the distribution of consumer types.
