Majone has written on a wide variety of subjects, but his most notable contribution concerns the EU's delegation of regulatory powers. In brief, Majone conceives of the delegation of regulatory powers to supranational institutions such as the European Commission as a means for member states to credibly commit to integration and implementing EU policies. Majone asserts that the scope of EU powers are primarily regulatory and contrasts delegation to the commission with national forms of delegation such as that to an independent central bank.
