In this paper, we estimate the effects of incompatibility on consumersin a classic hardware/software market: ATM cards and machines. We Þnd that while ATM feesceteris paribus reduce the network beneÞt from other banks? ATMs, a surge in ATM deploymentaccompanies the shift to surcharging. This is valuable to consumers and often completely offsetsthe harm from higher fees. The results suggest that policy discussions of incompatibility mustconsider not only its direct effect on consumers, but also its effect on product attributes.
