DESCRIPTION:Title: Testing Exclusion and Shape Restrictions in Potential 
 Outcomes Models (with Hiroaki Kaido) Abstract: Exclusion and shape restr
 ictions play a central role in defining causal effects and interpreting 
 estimates in potential outcomes models. To date\, the testable implicati
 ons of such restrictions have been studied on a case-by-case basis in a 
 limited set of models. In this paper\, we develop a general framework fo
 r characterizing sharp testable implications of general support restrict
 ions on the potential response functions\, based on a novel graph-based 
 representation of the model. The framework provides a unified and constr
 uctive method for deriving all observable implications of the modeling a
 ssumptions. We illustrate the approach in several popular settings\, inc
 luding instrumental variables\, treatment selection\, mediation\, and in
 terference. As an empirical application\, we revisit the US Lung Health 
 Study and test for the presence of spillovers between spouses\, specific
 ation of exposure maps\, and persistence of treatment effects over time.
