The legal form of labour conflicts and their time persistence: an empirical analysis with a large firms' panel

Using a panel of large firms from Spain, we check the relative time persistence of different types of labour conflicts such as strikes, collective conflicts, lockouts and other conflicts with lost working hours but without the previous stated legal forms for labour conflicts. We present random-effects probit estimations comparing observations with each type of conflicts with the same set of observations without any type of conflict. The results show that no legal form labour conflicts do not have long-term persistence (persistence is only in the short-term, from quarter to quarter), and the other types of conflicts suffer short and long-term persistence of confliction at the firm level, corresponds to strikes the higher size of both types of persistence. As short and long term persistence of strikes have almost the same size these results do not support asymmetric information theories of strike.
