I am thinking here about contributions in the 1960s and 1970s on the shape of the Phillips curve, research on time inconsistency that emerged from the late 1970s onwards, research on central bank independence in the 1980s and 1990s, and recent discussions on central bank accountability and communication.
Perhaps current researchers can take comfort in the fact that one day the outcomes of current scientific debates may also become glaringly obvious. But in the meantime we need to struggle on before science reveals the answer to us. Conclusion Let me conclude with a forward looking perspective.
