Abstract: The purpose of this paper is to study the consequences of using the Farrell and Shapiro (1990) sufficient condition for merger approval to sectors in which a downstream horizontal merger may also affect upstream firms. As will be shown below, in some circumstances the sign of the relevant external effect can no longer be established by considering the merger as a sequence of in finitesimal mergers, each corresponding to a marginal change in output.
