Motivated by recent findings in the field of consumer science, this paper evaluates the causal effect of debit cards on household consumption using population-based data from the Italy Survey of Household Income and Wealth (SHIW). Within the Rubin Causal Model, we focus on the estimand of population average treatment effect for the treated (PATT). We consider three existing estimators, based on...

We study the effect of government encouraged or mandated interchange fee ceilings on consumer and merchant adoption and usage of payment cards in an economy where card acceptance is far from complete. If the pre-regulatory interchange fee was optimal, any change in the interchange fee would result in lower aggregate welfare for consumers, merchants, and banks. Merchant acceptance of debit and c...

This paper analyzes the welfare implications of creating a Single Euro Payments Area.

In particular, we model competition among debit cards and between debit and credit cards. We show that competitive pressures dampen merchant fees and increase tot...

This paper studies product innovation and firm survival in the U.S. ATM/debit card industry. The industry started with a few shared ATM networks in the early 1970s. The number of networks grew quickly up until the mid 1980s, but then declined sharply. We construct a theoretical model based on Jovanovic and MacDonald (1994). In contrast to their model focusing on cost-saving technological innova...
