In this PLoS ONE article, Allen, Carbo, Chakravorti, Rodriguez, and Ardic use random forest estimation to 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...
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...
Payment cards continue to replace cash and checks in advanced economies. Along with the growth of payment card transactions has come greater scrutiny by public authorities of certain payment network rules along with the level of certain fees. Chakravorti reviews the growing payment card literature and discusses the impact of...
On June 21–22, 2010, the Chicago Fed and the University of Granada co-sponsored a conference that brought together policymakers, academics, and industry practitioners to discuss evolving retail payment systems and the role of public authorities, with several panels focusing on the Single Euro Payments Area.
While payment card usage has increased dramatically, the stock of outstanding currency has not declined as rapidly. Amromin and Chakravorti analyze changes in cash demand for 13 advanced economies from 1988 to 2003 by separating cash into three denomination categories to disentangle its store of wealth and payment functions. Defining...
Chakravorti and To construct a two-period model to study the interactions among consumers, merchants, and a card issuer. The model yields the following results. First, if the issuer's cost of funds is not too high and the merchant's profit margin is sufficiently high, in every equilibrium of our model the...
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...
Businesses, both small and large, are adopting new technologies to automate and reduce the exchange of paper documents in their transaction flows. However, more than 80% of payments between businesses are still made with paper checks. As the exchange of information along the supply chain becomes increasingly electronic, it raises...
The proportion of retail, non-cash payments made electronically in the U.S. grew from 15% in 1979 to 40% in 2000. A recent Chicago Fed conference addressed the important question of whether today's payment networks can adequately support emerging payment technologies.
