Revisiting the Case for a Populist Central Banker
It is known that discretionary policy may give rise to an inflationary bias if wages are negotiated in nominal terms. It has recently been argued that this bias can be eliminated, and welfare maximized, by the appointment of a central banker who does not care at all about inflation (a "populist" central banker). A conceptual flaw of the latter result is identified here. It is shown that when wages are negotiated in nominal terms the result is true only in the special case of a single, allencompassing, union. In the more general case of multiple unions, however, inflation increases linearly with their number and a populist central bank may turn out to decrease welfare.
