Ex-post, the central bank may choose inflation above the social optimum to reduce the real value of private debt.\n- This inefficient outcome occurs when macro-prudential policies cannot be adjusted as frequently as monetary policy.\n- The time inconsistency result holds even when the central bank is politically independent.\n- The paper extends the analysis to include political pressures in the spirit of Barro and Gordon (1983): if either the macro-prudential regulator or the central bank (or both) are not politically independent, separation of price and financial stability objectives does not deliver the social optimum."
