Higher RRE concentration is associated with lower returns especially for larger community banks?banks with assets totaling a billion or more.

Employing a difference-in-differences framework, we find that M&As are associated with increases in average markups, but find little evidence for effects on plant-level productivity. We also examine whether M&As increase efficiency through reallocation of production to more efficient ...
