The Nurturing of Relationships in Commercial and Retail Banking

ABSTRACT

The objective of this paper is to develop a better understanding of the factors associated with nurturing relationships between relationship managers and their clients in the banking industry. The Nominal Group Technique and a content analytical approach were both used to respectively collect and interpret the data. Results found the nurturing of relationships to be endogenous and asymmetrical in nature. The consequence is a personal, individualistic process maintained on behalf of the bank. The complexity associated with managing commercial portfolios requires commercial account managers to be more involved with their clients in the nurturing process than retail branch managers.

INVARIANCE OF THE UNORDERED BEST ESTIMATOR IN THE T,–CLASS FOR MIDZUNO'S AND FOR IKEDA–SEN'S SAMPLING PROCEDURES

MIDZUNO'S sampling procedure is considered where the first (n – 1) draws are carried out with simple random sampling without replacement and the nth draw with varying probabilities. It is shown that for this scheme, the best estimator in the HORVITZ–THOMPSON (1952) T_t–class of linear estimators exists and rejects the last draw. When MURTHY'S technique of unordering of an ordered estimator is employed, the rejected draw is restored and the unordered estimator is obtained. Surprisingly, this unordered estimator is the same as the unordered best estimator in the T₁–class, derived for IKEDA–SEN'S sampling procedure.
