where the restriction is rejected, we derive bounds to the Local Average Treatment Effect (LATE) based on weaker …

doctor visit. We employ nonparametric bounding techniques to minimise statistical assumptions. In order to tighten the bounds … low deductibles below zero. Adding the third assumption allows to tighten the bounds further. We conclude that there is a …

This paper examines changes in the distribution of wages using bounds to allow for the impact of non-random selection … into work. We show that bounds constructed without any economic or statistical assumptions can be informative. However … differentials. Thus we explore ways to tighten these bounds using restrictions motivated from economic theory. With these …

We derive nonparametric sharp bounds on average treatment effects with an instrumental variable (IV) and use them to … data, and some of our bounds do not require an outcome with bounded support. We employ these bounds to assess the …

Since the effect for volunteers is not point-identified, we employ bounds that rely on a … compliers, in line with prior literature. For volunteers, however, we document that their estimated bounds show statistically …
