We identify different sources of risk as important determinants of banks' corporate structures when expanding into new markets. Subsidiary‐based corporate structures benefit from greater protection against economic risk because of affiliate‐level limited liability, but are more exposed to the risk of capital expropriation than are branches. Thus, branch‐based structures are preferred to subsidiary‐based structures when expropriation risk is high relative to economic risk, and vice versa. Greater cross‐country risk correlation and more accurate pricing of risk by investors reduce the differences between the two structures. Furthermore, a bank's corporate structure affects its risk taking and affiliate size.

We examine how the informational structure of loan markets interacts with banks' strategic behavior in determining lending standards, lending volume, and the aggregate allocation of credit. We show that, as banks obtain private information about borrowers and information asymmetries across banks decrease, banks may loosen their lending standards, leading to an equilibrium with deteriorated bank portfolios, lower profits, and expanded aggregate credit. These lower standards are associated with greater aggregate surplus and greater risk of financial instability. We therefore provide an explanation for the sequence of financial liberalization, lending booms, and banking crises observed in many emerging markets.

We present evidence of a risk‐taking channel of monetary policy for the U.S. banking system. We use confidential data on banks’ internal ratings on loans to businesses over the period 1997 to 2011 from the Federal Reserve's Survey of Terms of Business Lending. We find that ex ante risk‐taking by banks (measured by the risk rating of new loans) is negatively associated with increases in short‐term interest rates. This relationship is more pronounced in regions that are less in sync with the nationwide business cycle, and less pronounced for banks with relatively low capital or during periods of financial distress.
