In this keynote presentation, Bob Chakravorti discusses how FinTech and big tech firms are increasing competition in the payments space. Entry into payments, often allows these non-bank providers the ability to offer loans to underserved consumers and small merchants. In the rest of the talk, Chakravorti discusses the effectiveness of...
Using random forest estimation, we identify 14 key predictors out of 190 variables with the largest predictive power for MSMR adoption and usage of digital payments. Using conditional inference trees, we study the importance of sequencing and interactions of various factors such as public sector initiatives, technological advancements, and private...
The adoption of electronic payments and their frequent use is thought of as a first step for broader financial use for traditionally unbanked individuals and merchants. The purpose of this report is to analyze the design, implementation, and efficacy of many incentives implemented by different types of stakeholders around the...
Carbó, Chakravorti, and Rodriguez study the impact of lowering interchange fees on consumer and merchant adoption and usage along with bank revenues during a ten-year period in Spain using bank-level data. Using cutting-edge econometric techniques, they are able to test two-sided market model predictions about payment card pricing policies. They...
In his presentation to Bank of Mexico economists and payment experts, Chakravorti presented an update of economic models that consider various forms of regulation.
Bolt and Chakravorti study the ability of banks and merchants to influence the consumer's payment instrument choice. Consumers participate in payment card networks to insure themselves against three types of shocks - income, theft, and their merchant match. Merchants choose which payment instruments to accept based on their production costs...
Bolt and Chakravorti explain how a payment network operates. Having established the payment network framework, they discuss the costs and benefits of providing and using payment cards relative to various other types of payment instruments. Next, they review the key contributions to the theoretical payment card literature. They consider papers...
Chakravorti and Jankowski summarize the 2005 Chicago Payments conference. The migration to more efficient payment mechanisms is affected by innovations, incentives, and regulations. While advances in technology have yielded numerous payment method alternatives, many have not been widely adopted. A Chicago Fed conference explored why certain payment innovations have been...
Chakravorti and Emmons model side payments in a competitive credit‐card market. If competitive retailers absorb the cost of accepting credit cards by charging a higher goods price to everyone, then someone must subsidize convenience users of credit cards to prevent them from defecting to merchants who do not accept cards...
Chakravorti and Roson construct a model to study competing payment networks, where networks offer differentiated products in terms of benefits to consumers and merchants. We study market equilibria for a variety of market structures: duopolistic competition and cartel, symmetric and asymmetric networks, and alternative assumptions about consumer preferences. We find...
