To unveil the strategic interaction between the government and the labour union in a unionised economy, a policy-game model is estimated by cointegrated Vector Autoregressive system using Italian quarterly data (1960-2009) on government budget surplus (fiscal efforts), hours not worked (strikes), unemployment and real wages. The long-run cointegration relationships are interpreted as the players' reaction functions and the long-run equilibrium as the equilibrium of the game. The identification of the long-run cointegration relationships allows indeed to determine if efforts and strikes are strategic complements or strategic substitutes. Finally, speed of long-run adjustment provides insights about the effectiveness of government and labour union strategies.
