Abstract

This paper considers identif cation of treatment effects on conditional transition probabilities. We show that even under random assignment only the instantaneous average treatment effect is point identi fied. Because treated and control units drop out at diff erent rates, randomization only ensures the comparability of treatment and controls at the time of randomization, so that long run average treatment effects are not point identifi ed. Instead we derive informative bounds on these average treatment effects. Our bounds do not impose (semi)parametric restrictions, as e.g. proportional hazards. We also explore various assumptions such as monotone treatment response, common shocks and positively correlated outcomes hat tighten the bounds.
