Stabilisation of common and asymmetric shocks
The stabilisation from market mechanisms and other existing instruments is bound, and this may be the economic rationale for fiscal stabilisation in a monetary union. Factor mobility really helps to smooth the result of large shocks (Asdrubali et al. 1996, Nikolov 2016), however the Great Recession showed that market stabilisation is normally inadequate (Berger et al. 2018) because markets have a tendency to behave pro-cyclically (Furceri and Zdzienicka 2015, Ferrari and Rogantini-Picco 2016).
