This paper investigates the behavioral goal of the Japanese banks have pursued. After constructing a simple model of banking behavior, it is firstly shown that the response of the scale-maximizing banks to changes in the call rate depends on their net position, while that of the profit-maximizing ones does not. Then the proposition is empirically examined by estimating the relation between the response to changes in the call rate and their net position with the data of bank financial statements from 1965 to 1982 to find that banks in borrowed position (city banks) decreased their deposits when the call rate increased, while the banks in lending position (local banks) increased. Thus, it is concluded that the Japanese banks can be considered to maximize their scale, not their profits, for the period up to the very recent year.
