"This paper analyses whether active labour market policies (ALMPs) have differing effects on unemployment and employment dynamics according to the particular region in which they are implemented. To this end, it analyses alternative theoretical and econometric models thought to capture the possible effects of active labour market policies on labour force dynamics. The econometric methodologies implemented are the generalized method of moment (GMM) and the panel vector autoregression (P-VAR). The evidence yielded by the GMM models suggests that the effects of different ALMPs on unemployment are dissimilar across the Italian regions. It follows that some active programmes are likely to have a greater effect in the South than in the North. The results of the P-VAR models estimated are synthesized by impulse response analysis and forecast error variance decomposition. The impulse response analysis suggests that an increase in total ALMP gives rise to: (i) a decrease in the unemployment rate; and (ii) a significant increase in labour force participation. More interestingly, the results obtained from the error variance decomposition analysis show that unemployment movements are not driven by shocks in the ALMPs and that, especially in the northern regions, atypical contracts shocks account for a substantial portion of unemployment dynamics."

"This paper explores the role that the imperfect knowledge of the structure of the economy plays in the uncertainty surrounding the effects of rule-based monetary policy on unemployment dynamics in the euro area and the US. We employ a Bayesian model averaging procedure on a wide range of models which differ in several dimensions to account for the uncertainty that the policymaker faces when setting the monetary policy and evaluating its effect on real economy. We find evidence of a high degree of dispersion across models in both policy rule parameters and impulse response functions. Moreover, monetary policy shocks have very similar recessionary effects on the two economies with a different role played by the participation rate in the transmission mechanism. Finally, we show that a policy maker who does not take model uncertainty into account and selects the results on the basis of a single model may come to misleading conclusions not only about the transmission mechanism, but also about the differences between the euro area and the US, which are on average essentially small."
