We examine changes in risk following US bank mergers in the period 1981-2014. Short-run increases in acquirer risk following mergers occur only in the first few mergers undertaken by the same acquirer, and only in systematic risk. The equity volatility of acquirers does not increase. Using a new...

Using a large sample of cross-border mergers we measure the effect of a change in location on systematic risk. When a target firm's location moves a large part of its systematic risk switches from being related to its home equity market to that of the acquirer. On average the change in betas is...

We examine the changes in betas resulting from international mergers. We find that the beta with respect to the acquirer's home market rises and that with respect to the target's home market falls. This effect is robust with respect to controls for changes in the operations of the companies...

Using a large sample of cross-border mergers we measure the effect of a change in location on systematic risk. We document a large, widespread, and robust effect. When a target firm's location moves as a result of an international merger, a large part of its systematic risk switches from being...
