The empirical results show that strike probabilities are higher following a longer contract, and lower in limited reopening situations. Strike probabilities are also higher in summer and fall than in winter and spring. Finally, strike probabilities are significantly affected by lagged strike outcomes. Relative to a peaceful settlement, strike probabilities are 10 percentage points higher following a strike of two weeks or less, and 5 to 7 percentage points lower following a longer dispute UR - https://www.nber.org/papers/w2263 UR - http://dx.doi.org/10.3386/w2263 ER -
