The possibility that large-scale structure in the galaxy distribution is the result of quasars modulating galaxy formation in the standard CDM model is explored. Specifically, the case where radiation from high-redshift quasars is assumed to suppress galaxy formation in their neighborhood is considered. The observed quasar population can, in principle, influence large enough regions of space to reconcile the CDM model with recent measurements of large-scale structure. In such a model the observed voids should contain failed galaxies and galaxy clusters.
