Abstract
Internet-based banks use a technology-intensive production process that may benefit from scale effects as they grow larger. This article analyzes whether the predominant Internet-primary bank in the USA generates technology-based economies of scale in the period 2002–2010. There is evidence of both favorable and adverse technology-based scale effects. As the leading Internet-primary bank gets larger, the financial performance gap with traditional banks shrinks while some of its critical competitive advantages wear down. The results suggest that unless the prevailing Internet-primary bank preserves the distinctive advantages of the Internet-based business model as it improves financial performance, it might end up converging with its branching competitors.

Notes
We chose a ± 10% range because the resulting sample includes a nearly balanced number of greater (10) and smaller (9) banks than ING Bank. Had we chosen either a narrower or a wider range (e.g., 5% or 15%), the resulting sample would be clearly uneven.
For a recent review see Hsiao (2007).
