\noindent {\it Abstract:}
The paper considers improving the efficiency of parameter estimation of the
quasi-likelihood in generalized linear models. The improvement is offered by
employing the empirical likelihood and incorporating extra constraints which
better utilize the provided variance structure of the models. We recommend a
particular choice for the extra constraints to reduce the variance of the
quasi-likelihood based parameter estimators.\par
