Is the Market Well Defined in Bank Merger and Acquisition Analysis?
检验了两个假设：银行服务的合适地理市场是全国性而非地方性，以及将所有银行服务定义为银行产品是否过于宽泛。
Two hypotheses are tested in this paper. The first is whether the appropriate geographic market for certain banking services is national, instead of local. The second is whether the definition of banking product as all banking services is too broad. Copyright 1992 by MIT Press.
