Using Secondary Outcomes to Sharpen Inference in Randomized Experiments With Noncompliance
We develop new methods for analyzing randomized experiments with noncompliance and, by extension, instrumental variable settings, when the often controversial, but key, exclusion restriction…
The effects of trading activity on market volatility
The paper re-examines the question of excessive implied persistence of volatility estimates when GARCH type models are used. Ten actively traded US stocks are considered and as already established in…
Exploiting instrumental variables in causal Inference with nonignorable outcome nonresponse using principal stratification
In this paper we consider a specific post-treatment complication that may arise in both randomized and observational studies, namely the problem of nonignorable nonresponse on an outcome variable.…

Unless strong assumptions are made, nonparametric identification of principal causal effects can only be partial and bounds (or sets) for the causal effects are established. In the presence of a…
