Abstract

Previous research on market concentration in banking is heavily tilted towards using deposits as the underlying variable for measuring market concentration. This paper proposes a change in methodology by replacing deposits with the Variable profit function based on Barnett and Hahm’s Economic model for Financial Institutions, used in their 1994 paper. This model has also been successfully used in Dr. William A. Barnett’s successive research. Hancock 1997 also proposes using a similar methodology for modelling banks as Economic firms. Results change dramatically once deposits are substituted by variable profits, and a confounding puzzle is solved, involving one of South Asia’s thriving banking markets.

对市场集中度和竞争的新见解：利用Barnett的可变利润函数来衡量银行业的市场结构

此前对银行业市场集中度的研究主要倾向于将存款作为衡量市场集中度所依据的变量。本文根据Barnett和Hahm在1994年的论文中使用的金融机构经济模型，提出了一种方法上的改变，用可变利润函数代替存款。该模型也成功地应用于William A.Barnett博士的连续研究中。汉考克1997年还建议使用类似的方法将银行建模为经济公司。一旦存款被可变利润取代，结果就会发生巨大变化，一个令人困惑的难题也就迎刃而解，这涉及到南亚繁荣的银行市场之一。

期刊介绍： The Journal of Economic and Social Measurement (JESM) is a quarterly journal that is concerned with the investigation of all aspects of production, distribution and use of economic and other societal statistical data, and with the use of computers in that context. JESM publishes articles that consider the statistical methodology of economic and social science measurements. It is concerned with the methods and problems of data distribution, including the design and implementation of data base systems and, more generally, computer software and hardware for distributing and accessing statistical data files. Its focus on computer software also includes the valuation of algorithms and their implementation, assessing the degree to which particular algorithms may yield more or less accurate computed results. It addresses the technical and even legal problems of the collection and use of data, legislation and administrative actions affecting government produced or distributed data files, and similar topics. The journal serves as a forum for the exchange of information and views between data producers and users. In addition, it considers the various uses to which statistical data may be put, particularly to the degree that these uses illustrate or affect the properties of the data. The data considered in JESM are usually economic or social, as mentioned, but this is not a requirement; the editorial policies of JESM do not place a priori restrictions upon the data that might be considered within individual articles. Furthermore, there are no limitations concerning the source of the data.
