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 show how to calculate the after-tax value of real options, including the value of interest tax shields on debt supported or displaced by the options. An option's “debt capacity” can be calculated from the adjusted present value (APV) and target debt ratio for the underlying asset, the...

It is common to assert that utility investors are compensated in the allowed rate of return for the risk of large disallowances, such as arise for investments found imprudent or not `used and useful'. However, this book develops a new theory of asymmetric regulatory risk that shows that...

We show how the value of a real option depends on corporate income taxes and the option's "debt capacity," defined as the amount of debt supported or displaced by the option. The value of the underlying asset must be an adjusted present value (APV). The risk-free rate of interest must be...
