This paper first inverts a general class of matrices for solving Bertrand equilibria from arbitrary coalition structures in linear Bertand oligopolies. It then studies merger incentives and obtains two main results; 1) for any asymmetric costs, mergers of any size are profitable; 2) a merger will...

A correctly specified time series model can be used to transform the data set to obtain an i.i.d. sequence of random variables, assuming that the true parameter values are known. In reality, however, one only has an estimated model and must therefore address the sampling error associated with...
