Abstract: Sunk capital as an entry-barring commitment has recently been a focus of the literature on barriers to entry. This paper introduces potential entrants with absolute cost disadvantage which decreases over time and, by doing so, endogenizes time of entry. In this decreasing cost disadvantage model, a monopolist may choose its capacity below the optimal level in an entry-free setting, so as not to have inefficiently large capacity after entry occurs. Also he may carry capacity which will be excess in the posentry equilibrium, in order to increase his pre-entry profit. This paper also analyzes how the equilibrium changes when a patent is introduced. One finding is that a patent may shorten the equilibrium time of entry.
