Before revision:  These restrictions generate moment inequalities and therefore set identification , which can lead to wide confidence sets for the structural parameters. The paper shows that employing aggregated survey data that are informative about the extensive margin of adjustment i.e. the proportion of agents whose behavior is distorted over time due to financial frictions  can provide additional information that can tighten the corresponding bounds.
