“…Edwards (19771, in a path-breaking study of the banking industry, found strong evidence for the expense preference theory of managerial behavior, and related his results to a pervasive regulatory environment. Later studies by Hannan (1979), Hannan andMavinga (19801, Arnould (1989, andGropper andOswald (1995) found evidence of expense preference behavior among commercial banks, while Akella and Greenbaum (1988) and Verbrugge and Jahera (1981) found evidence to support similar conditions for savings and loan associations. In contrast to these findings, studies by Blair and Placone (1988) and Mester (1989) found, at best, very weak support for expense preference, and little evidence of significant differences in expense preference activities between stock and mutual ownership forms.…”
