The Dynamics of Market Entry: The Effects of Mergers and Acquisitions on Entry in the Banking Industry

摘要

We study the dynamics of market entry following mergers and acquisitions (M&As) using banking industry data. The findings suggest that M&As are associated with statistically and economically significant increases in the probability of entry. The data suggest that M&As affect the proportion of the markets with entry by about 10-20%. These findings also suggest that entry may be part of an "external" effect of M&As that helps supply credit to some relationship-dependent small business borrowers. Our results are robust to the use of alternative econometric methods, changes in specifications of the exogenous variables, and alteration of the data samples.
