The emergence of the seeds of cosmic structure from an isotropic and homogeneuous universe has not been clearly explained by the standard version of inflationary models. We review a proposal that attempts to deal with this problem by introducing "the self induced collapse hypothesis". As a consequence of this modification of standard inflationary scenarios, the predicted primordial power spectrum and the CMB spectrum are modified. We show the results of statistical analyses comparing the predictions of these models with recent CMB observations and the matter power spectrum from galaxy surveys.
