Abstract
We study the competitive behavior of the two largest US Banks
before and after the financial crisis that started in 2007. The analysis
documents that JP Morgan Chase, the initially smaller of the two rivals,
followed a competitive strategy aiming to expand its lending to catch up with
the leading private lender, the Bank of America. By contrast, the latter bank
did not engage in an expansionary push to keep its quantitative advantage.
Instead, it opted to diversify its lending portfolio and to invest in technological
advances. This assessment is supported by econometric estimates and
counterfactual simulations. With its strategy of quality over quantity the Bank
of America refrained from engaging in herd behavior which could have led to a
new upswing of the credit cycle.
