We model the impact of bank mergers on loan competition, banks' reserve holdings and aggregate liquidity. 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...

We show that competing firms relax overall competition by lowering future barriers to entry. We illustrate our findings in a two-period model with adverse selection where banks strategically commit to disclose borrower information. By doing this, they invite rivals to enter their market....

The aggregate Lerner index is a popular composite measure of multi-product banks' market power, based on the assumption that banks' single aggregate output factor is total assets. This study identifies three limitations of the aggregate Lerner index that potentially distort its interpretation as...

This paper studies bank competition with borrower adverse selection. In the model, expected non-performing loan costs are high when credit is granted in booms, when risk free rates are low, or when competition is strong. I prove that full competition is suboptimal due to this last effect; that...

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...

Recent experience from Europe and Japan shows that commercial banks generally pass negative short-term policy rates on to wholesale depositors, such as insurances and pension funds. Yet, they refrain from charging negative rates to ordinary retail customers. This paper asks whether the existing...

To the surprise of many, price deviations between markets characterized by imperfect competition have often been little affected by lower transport costs. In a Cournot model we show that if firms' decisions to segment markets are endogenous, then lower transport costs are, in many cases,...

We study the profitability incentives of merger and the endogenous industry structure in a strategic trade policy environment. Merger changes the strategic trade policy equlilibrium. We show that merger can be profitable and welfare enhancing here, even though it would not be profitable in a...
