Breast cancer screening is an integral part of the cancer control strategies of many developed economies. In Britain individuals screened in a given year are re-called every three years unless results indicate a need for more immediate investigation. This pattern may create a legacy arising from...

We propose a framework for estimation and inference about the parameters of an economic model and predictions based on it, when the model may be misspecified. We rely on a local asymptotic approach where the degree of misspecification is indexed by the sample size. We derive formulas to...
