Abstract: This paper uses the context of online banking to investigate the consequences of using self-service distribution channels to alter customer interactions with the firm. Using a sample of retail banking customers observed over a 30-month period at a large U.S. bank, we test whether changes in service consumption, cost to serve, and customer profitability are associated with the adoption of online banking. We find that customer adoption of online banking is associated with (1) substitution, primarily from incrementally more costly self-service delivery channels (automated teller machine and voice response unit); (2) augmentation of service consumption in more costly service delivery channels (branch and call center); (3) a substantial increase in total transaction volume; (4) an increase in estimated average cost to serve resulting from the combination of points (1)-(3); and (5) a reduction in short-term customer profitability. However, we find that use of the online banking channel is associated with higher customer retention rates over one-, two-, and three-year horizons. The documented relationship between the use of online banking and customer retention remains positive even after controlling for self-selection into the online channel. We also find evidence that future market shares for our sample firm are systematically higher in markets with high contemporaneous utilization rates for the online banking channel. This finding holds even after controlling for contemporaneous market share, suggesting it is not simply the result of increased market power leading to the acquisition of online banking customers.
