This paper documents the importance of nonbanks in retail payments in the United States and in 15 European countries and analyses the implications of the importance and multiple roles played by nonbanks on retail payment risks. Nonbanks play multiple roles along the entire payment processing...

This paper studies the diffusion and impact of a cost-saving technological innovation — Internet banking. Our theory characterizes the process through which the innovation is adopted sequentially by large and small banks, and how the adoption affects bank size distribution. Applying the theory...

Taking internet banking as an example, we study diffusion of cost-saving technological innovations. We show that the diffusion of internet banking follows an S-shaped logistic curve as it penetrates a log-logistic bank-size distribution. We test the theoretical hypothesis with an empirical study...

From the early days of automated card sorting to the more recent times of the Internet and check imaging, payments and payments processing have continually embraced new technology. At the same time, the industry has been shaped by its share of entry and exit, through startups, mergers, and the...

Nonbank providers of payment services are important in the United States and appear to have become more prominent in recent years. This development, by itself, poses unique risks to the payments system. Associated with this change is a significant transformation in the mix of payment types away...

Innovations in financial services continuously influence the scope of financial intermediation and the nature of competition between intermediaries. This paper examines the optimal exercise of strategic real options to invest in such an innovation, Internet banking technology, within a two-stage...

An industry typically experiences initial mass entry and later shakeout of producers over its life cycle. It can be explained as a competitive equilibrium outcome driven by the dynamic interaction between technology progress and demand diffusion. When a new product is introduced, high-income...

This paper provides a theory of two-sided market dynamics with arguably better microfoundations. These alternative microfoundations focus on observable heterogeneities of both sides of the market in a competitive framework. The theory is rich in empirical predictions and is less dependent on a...
