The problem of estimation of domain mean under random response mechanism has been considered when the sampling design is two-stage with two phases at the second stage. A estimator is developed based on the technique of sub sampling of non-respondents. Expressions for the variances of the estimators are developed. Optimum values of sample sizes are obtained by considering a suitable cost function. The percentage reduction in the expected cost of proposed estimators is studied empirically.
