Moreover, this union has proved to be fragile after the recent economic shocks: this is the second issue dealt with in the paper. In particular, the austerity measures undertaken to face the sovereign debt crisis, especially in the peripheral countries, have caused a prolonged recession, stagnation and persistent unemploymen
