IN THE LAST DOZEN YEARS there has been a modest increase in the number of newly chartered black-controlled savings and loan associations. Starting from a base of 28 associations in 1960, by year end 1974 there were 41 FSLIC insured blackcontrolled associations. Much of this expansion has been attributed to a need for central city mortgage finance in districts populated by low-income ethnic minorities.' While we do not question the scarcity of mortgage finance in certain communities, the potential for black-controlled associations to supply long-term mortgage instruments is critically dependent on their ability to compete for deposits and to operate efficiently in the urban markets in which they reside. What is the competitive position of black associations? How efficient have seasoned associations become in providing financial services in their communities? Slight evidence regarding these questions is available. A recent study by Bradford [3], for example, examines the ability of a group of predominantly black minority associations to operate profitably. Utilizing ratio analysis, Bradford reports that minority associations had a higher ratio of operating expenses to gross income and thus a lower ratio of net to gross income when compared to a similar sample of white-controlled associations. Commenting on costs, Bradford finds higher compensation expense in minority associations.2 This resulted in lower rates of return for minority associations. Ratio analysis, although informative, does not clearly identify the economic causes for observed differences in performance. Accordingly, we review the revenue and cost structure expressed as annual rates per deposit dollar. Furthermore, by modelling the profit maximizing behavior of a financial intermediary we are able to econometrically separate the operating cost rate into financial production costs and implicit deposit rates for a group of black controlled associations and a matched white comparison sample. The results indicate that black associations earned higher rates on deposits and paid lower, explicit and implicit deposit rates. The spread between the asset and deposit rates for these associations was larger than the comparable white sample. Despite this larger rate spread, black associations were less profitable as their
