Hi everyone,

I am trying to estimate the impact of a hiring subsidy on the survival rate of employers using non-experimental data. My data includes information on a flow sample of new employers during 28 quarters including whether they benefitted from the subsidy when hiring employees. I want to use a discrete time proportional hazard model with frailty to estimate the effect of the subsidy. However, by construction the hazard rate is zero when employers receive the subsidy. In order to correctly estimate the effect of the subsidy, I would have to set the hazard rate to zero in the periods when the subsidy is awarded. Is it possible to set hazard rates to a specific value in hshaz?

I hope this is sufficiently clear and thank you very much for any suggestions.
