ON NONRESPONSE CAUSALITY TESTING IN ROTATING PANEL DESIGNS UNDER THE COX MODEL

High survey nonresponse in unemployment duration studies may have a Oven Door Switch strong effect on inference if exit from unemployment affects the chance of nonresponse (nonresponse causality).In rotational studies large part of the nonresponse results from panel attritions.A method to test the presence of the causality CURL FORCE 17 mechanism for rotating panel designs is proposed and its asymptotic consistency is proved under the Cox regression model.An application to real labor data and a simulation study are shown.
