I have a problem, where I am using hazard model. Database includes around 100 firms that are/are not adopting technology. Around 35 firms adopt technology, so my adoption variable (y = dependent variable) becomes 1 from 0 when adoption occurs. Around 45 firms do not adopt and their y variable stays 0 for the entire time of study. Remaining firms disappear from data because they go bankrupt. So, y variable is also 0. Does bankruptcy in this case, a competing risk? I am curious because y variable is 0 (and not turning to 1) during this period of study. How do I account for these 10 firms in my model? What are some arguments related to bias if I ignore bankruptcy and treat these 10 firms simply as firms which did not adopt technology?
