Abstract: Abstract The past two decades have been characterized by a wave of bank mergers that have reshaped both the US and the European financial systems. Specifically, the number of banks fell by almost 40 per cent in Europe and by over 45 per cent in the US between 1985 and 2003. The possibility that these bank mergers will yield efficiency gains for the consolidated banks has long been a subject of debate; yet empirical evidence documented in the literature up to 2000 does not provide an unambiguous answer to this question (see Amel et al. 2004). The consensus view from more recent studies is that bank mergers and acquisitions (M&As) can improve efficiency (see DeYoung et al. 2009). However, a probably more important issue is whether or not stock markets can accurately forecast these efficiency gains upon the announcement of an M&A operation.
