WebThis method is known as dyadic clustering, denoted here ‘DC’, and we let DCdenote the covariance matrix under the Fafchamps and Gubert (2007) assumption. Fafchamps and Gubert (2007) propose a simple way to estimate the elements in DC: Covd(˘ ij;˘ kl) = r ijr kl, where r ijand r klare the residuals of the corresponding relations.

WebHowever, we derive the result that the dyadic clustering estimator is biased downwards, and that this bias is larger than twice the bias of the exchangeable estimator.
