The extent of petition is related to the geographic overlap of banks in different markets and their relative market share in terms of deposits. In particular, banks adopt online banking services earlier in markets where their petitors have already adopted this technology. This paper is one of the first to construct local banking markets using the geographic market definitions delimited by the CASSIDIJEL classification:O31。L10。Technological adoption。Competition1. IntroductionThe arrival of the Internet not only spurred the development of new industries but it also changed the business model of many others, including the banking sector in the United States. In 1995, the Security First Network Bank was the first Internetonly bank created. Around the same time, Wells Fargo was the first brick andmortar bank to establish its online presence. For most of the remaining banks, however, online presence in the first few years simply meant only the creation of a static corporate website. Banks soon started to develop software applications that first allowed customers to access their accounts and later allowed them to perform financial operations online. By the end of 2003, more than half of the mercial banks in the United States offered some online banking services to their customers. This paper analyzes the determinants of a bank’s decision to adopt online banking. In particular, we focus on the strategic considerations of this adoption, mainly in response to the adoption decisions of petitors in the same market. We show that banks that operate in markets where petitors have already adopted online banking tend to adopt online banking services effect persists even after controlling for the standard measures of the degree of petition in the market and other market measures, such as size, as well as standard measures of a bank’s financial health are also important determinants.A considerable segment of the literature, particularly in the field of industrial organization, regards the optimal adoption of new technologies by a firm. For example, Oster (1982) studies the introduction of the basic oxygen furnace used in steel making. She approaches this decision as technologically driven, independent of the decisions made by Later papers have introduced strategic consider
