We propose a spatial competition model to study banks’ strategic responses to the asymmetric Spanish geographic deregulation process. We find that once the geographic deregulation process finishes, inter-regional mergers between savings banks are optimal whenever the economies of scale...

This paper examines the evolution of market structure in emerging markets banking systems during the 1990s. While a significant process of bank consolidation has been taking place in these countries, reflected in a sharp decline in the number of banks, this process has not systematically been...

The 1994 Riegle-Neal Act (RN) removed restrictions on branch-network expansion for banks in the United States. An important motivation was to facilitate geographic risk diversification (GRD). Using a factor model to measure banks' geographic risk, we show that RN expanded GRD possibilities in...

Open banking facilitates data sharing consented by customers who generate the data, with a regulatory goal of promoting competition between traditional banks and challenger fintech entrants. We study lending market competition when sharing banks' customer data enables better borrower screening...

This paper examines the evolution of market structure in emerging market banking systems during the 1990s. While significant bank consolidation has been taking place in these countries, reflected in a sharp decline in the number of banks, this process has not systematically been associated with...

Without regulation, securitization allowed mortgage industry actors to gain fees and to put off risks. During the housing boom, the ability to pass off risk allowed lenders and securitizers to compete for market share by lowering their lending standards, which activated more borrowing. Lenders...

This paper studies the integration of deposit and loan markets, which may be constrained by the geographic dispersion of depositors, borrowers, and banks. This dispersion results in problems of asymmetric information, monitoring and transaction costs, which in turn may prevent deposits from...

It has been argued that cognitively constrained consumers respond sub-optimally to complex decision problems, and that firms can exploit these limitations by introducing spurious complexity into tariff structures, weakening price competition. We model a countervailing force. Restricting one's...

This paper studies shopping hour decisions by retail chains and independent competitors. We use a Salop-type model where retailers compete in prices and shopping hours. Our results depend significantly on efficiency differences between retail chain and independent retailer. If the efficiency...

We investigate the effect of competition on quality in regulated markets (e.g., health care, higher education, public utilities), using a Hotelling framework, in the presence of sluggish demand. We take a differential-game approach, and derive the open-loop solution (providers choose the optimal...
