Tolerating de ance ? Local average treatment e ects without monotonicity . ∗
Instrumental variable (IV) estimates a causal e ect if the instrument satis es a monotonicity condition. When this condition is not satis ed, we only know that IV estimates the di erence between the e ect of the treatment in two groups. This di erence could be a very misleading measure of the treatment e ect: it could be negative, even when the e ect is positive in both groups. There are a larg...
متن کاملHeterogeneous Treatment Effects: Instrumental Variables without Monotonicity?
Heterogeneous Treatment Effects: Instrumental Variables without Monotonicity? A fundamental identification problem in program evaluation arises when idiosyncratic gains from participation and the treatment decision depend on each other. Imbens and Angrist (1994) were the first to exploit a monotonicity condition in order to identify an average treatment effect parameter using instrumental varia...
متن کاملFunctional Monitoring without Monotonicity
The notion of distributed functional monitoring was recently introduced by Cormode, Muthukrishnan and Yi [4] to initiate a formal study of the communication cost of certain fundamental problems arising in distributed systems, especially sensor networks. In this model, each of k sites reads a stream of tokens and is in communication with a central coordinator, who wishes to continuously monitor ...
متن کاملLocal Polynomial Wavelet Estimation of Local Average Treatment Effect∗
In this paper, we introduce a new class of estimators of jump size in a nonparametric regression model and apply it to the estimation of local average treatment effect (LATE). We refer members of this class as local polynomial wavelet estimators and show that all the existing estimators, including estimators constructed from differencing two nonparametric estimates and partial linear estimators...
متن کاملLocal Monotonicity Reconstruction
We investigate the problem of monotonicity reconstruction, as defined by Ailon, Chazelle, Comandur and Liu (2004) in a localized setting. We have oracle access to a nonnegative realvalued function f defined on the domain [n] = {1, . . . , n} (where d is viewed as a constant). We would like to closely approximate f by a monotone function g. This should be done by a procedure (a filter) that give...
