Banks compete in a differentiated loan market, hold reserves against liquidity shocks, and refinance in the interbank market. A merger creates an internal money market that induces financial...

Empirical research about structure, conduct and performance in banking markets has developed mostly independently from the microeconomic theory of banking.

We model the impact of bank mergers on loan competition, reserve holdings and aggregate liquidity. A merger creates an internal money market that affects reserve holdings and induces financial cost advantages, but also withdraws liquidity from the interbank market. Loan market competition...

We study how information sharing between banks influences the geographical clustering of branches. A spatial oligopoly model first explains why branches cluster and how information sharing impacts price competition and equilibrium clustering. With data on 59,333 branches of 676 banks in 22...

Since the push towards central clearing in derivatives markets after the global financial crisis, an open question has been how the development has affected competition. This paper models imperfect competition between dealers in derivatives markets. Two risk-neutral dealers offer derivatives to...

This study evaluates the effects of institutional investors' common ownership of firms competing in the same market. Overall, common ownership has two opposing effects: (a) it serves as a device for weakening market competition, and (b) it induces diversification, thereby reducing portfolio...
