Market Concentration and Uniform Pricing: Evidence from Bank Mergers

Staff Working Paper 2021-9 João Granja, Nuno Paixao
We show that US banks price deposits almost uniformly across their branches and that this pricing practice is more important than increases in local market concentration in explaining the deposit rate dynamics following bank mergers.

On Causal Networks of Financial Firms: Structural Identification via Non-parametric Heteroskedasticity

Staff Working Paper 2020-42 Ruben Hipp
Various business interactions of banks create a network of hidden relationships, which cannot be directly inferred from the correlation of bank stock returns.

Trading on Long-term Information

Staff Working Paper 2020-20 Corey Garriott, Ryan Riordan
Investors who trade based on good research are said to be the backbone of stock markets: They conduct research to discover the value of stocks and, through their trading, guide financial prices to reflect true value.

Welfare Analysis of Equilibria With and Without Early Termination Fees in the US Wireless Industry

Staff Working Paper 2020-9 Joseph Cullen, Nicolas Schutz, Oleksandr Shcherbakov
The elimination of long-term contracts and early termination fees (ETFs) in the US wireless industry at the end of 2015 increased monthly service fees by 2 to 5 percent. Nevertheless, consumers are clearly better off without ETFs. While firms’ revenues from ETFs vanish, their profits from monthly fees increase. As a result, the overall effect on producer profits is less clear.

Using a two-stage model, we study the determinants of Canadian consumers’ choices of payment method at the point of sale. We estimate consumer preferences and adoption costs for various combinations of payment methods. We analyze how introducing a central bank digital currency would affect the market equilibrium.

A Spatial Model of Bank Branches in Canada

Staff Working Paper 2020-4 Heng Chen, Matthew Strathearn
Using data on bank branch locations across Canada from 2008 to 2018, we explore an interesting aspect of bank branch competition—geographic concentration. We find that bank branch density does not correlate with geographic and market concentration; however, we do find strong correlation with postal-code demographics.
