I was intrigued by Munchau’s editorial on central bank independence, that appeared on today’s FT. Munchau argues that central banks’ choices are increasingly political in nature, especially if their mandate is broad, as is the case for example of the Fed. His argument is that a broad mandate implies tradeoffs, and as such it does not go well with central bank independence.
I must say I am unconvinced to say the least, on at least two levels.
First, I do not see how a strict mandate would make central bank choices less political in nature. It makes them more opaque, but by no means less political. I wrote about this in a paper on ECB action during the crisis, and more succinctly in an op-ed for Social Europe co-written with Yan Islam back in 2015. Let me quote a few excerpts from that piece:
A dual mandate requiring the central bank to pursue two, sometimes conflicting, objectives forces the institution to make inherently political choices. Far from being a shortcoming, this allows for a more flexible and unbiased monetary policy. A central bank following a dual mandate will always be able to take an aggressive stance on inflation, if it deems this necessary. Appropriate choice of the weights given to employment and inflation would allow incorporation of any combination of the two objectives. […]
Inflation-targeting central banks, such as the ECB, de facto also target growth but timidly and without explicitly saying so. This leads to low reactivity and opaque communication, hampering in turn the capacity of central banks to manage expectations and effectively steer the economy. A good case in point is the ECB that – compared to the Fed – did “too little and too late” from 2009, amid a constant debate on whether the inflation-targeting mandate was being violated. […]
ECB opacity is intrinsically linked to the confusion between its mandate and its activities in the real world, and as such it cannot lead to any meaningful discussion but only to legalistic disputes on the definition of price stability, of how medium is the medium term and the like.
The main merit of a dual mandate is in fact that it lets the political nature of monetary policy emerge without ambiguities. It is indeed true that monetary policy with a dual mandate requires hard choices, just like those debated these days, and hence is political by its very nature. The point is, so is monetary policy with a simple inflation-targeting objective. The level of inflation targeted, and the choice of the instruments to attain it, is anything but neutral in terms of its consequences on the economy. Thus, an inflation-targeting central bank is as political in its actions as a bank following a dual mandate, the only difference being that In the former case the political nature of monetary policy is concealed behind a technocratic curtain.
In a sentence, we argued that monetary policy choices are always political, and as such they should be incorporated in the policy mix, without hiding behind what Yan and I called a technocratic illusion.
Munchau’s link between the broadness of the mandate and its political nature, is simplistic and in my opinion strongly misleading. In fact, we concluded back in 2015 that it is linked to a specific intellectual framework
The profound justification of an exclusive focus on price stability can only lie in the acceptance of a neoclassical view in which virtually powerless governments need to make little or no choices. Once we dismiss that platonic view, monetary policy acquires a political role, regardless of the mandate it is given.
The second reason why Munchau’s argument is unconvincing is the conclusion, somewhat implicit in his piece, that a central bank making political choices needs to be a “government agency”. Why is it so, exactly? I fail to see it. What matters is not that the central bank is controlled by the finance ministry, but that it is accountable, like any other actor doing policy, in a system of well functioning checks and balances.
Once we recognize that a central bank has a political role, we need to make sure first, that its mandate is not falsely perceived as technocratic; and second, that its actions are properly embedded in a balanced policy mix, in which there is coordination with, not subordination to, the other branches of government. It seems to me that the US institutional system comes pretty close to this. The same cannot be said for the eurozone.
Thanks to the invaluable Economist’s View, I have read with lots of interest the speech that newly appointed Federal Reserve Board Member Lael Brainard gave last Monday. The speech is a plea for holding on rate rises, and uses a number of convincing arguments. Much has been said on the issue (give a look at comments by Tim Duy and Paul Krugman). I have little to add, were it not for the point I made a number of times, that the extraordinarily difficult task of central bankers would be made substantially easier if fiscal policy were used more actively.
What I’d like to express here is my jealousy for the discussions (and the confrontation) that we observe in the US. These discussions are a sideproduct, a very positive one if you ask me, of the institutional design of the Fed. I just returned from a series of engaging policy meetings on central bank policy in Costa Rica, facilitated by the local ILO office, where I pleaded for the introduction of a dual mandate.
I wrote a background paper (that can be seen here) in which my main argument is that a central bank following a dual mandate will always be able to take an aggressive stance on inflation, if it deems it necessary to do so. Appropriate choice of the weights given to employment and inflation would allow incorporation of any combination of the two objectives. A good case in point are the United States, where the Federal Reserve under Chairman Volcker embarked on a bold disinflation program in the early 1980s when the country had just adopted the dual mandate. No choice of weights, on the other hand, would allow a central bank following an inflation targeting mandate to explicitly target employment as well. Thus, the dual mandate can embed inflation targeting strategies, while the converse is not true. In terms of policy effectiveness, therefore, the dual mandate is a superior institutional arrangement.
I also cited evidence showing, and here we come at my jealousy for the Fed, that inflation targeting central banks, like the ECB, de facto target the output gap, but timidly and without explicitly saying so. This leads to low reactivity and opaque communication, that hamper the capacity of central banks to manage expectations and effectively steer the economy. I am sure that those who followed the EMU policy debate in the past few years will know what I am talking about.
One may argue that the cacophony currently characterizing the Federal Reserve Board is hardly positive for the economy, and that in terms of managing expectations, lately, the Fed did not excel. This is undeniable, and is the result of the Fed groping its way out of unprecedented policy measures. The difference with the ECB is that for the Fed the opacity results from an ongoing debate on how to best attain an objective that is clear and shared. We are not there yet, but the debate will eventually lead to an unambiguous (and hopefully appropriate) policy choice. The ECB opacity, is intrinsically linked to the confusion between its mandate and its actual action, and as such it cannot lead to any meaningful discussion, but just to legalistic disputes on the definition of price stability, of how medium is the medium term and the like.
And I can now come to my final point: a dual mandate has the merit to let the political nature of monetary policy emerge without ambiguities. It is indeed true that monetary policy with a dual mandate requires hard choices, as the ones that are debater these days, and hence is political in nature. The point is, that so is monetary policy with a simple inflation targeting objective. The level of inflation targeted, and the choice of the instruments to attain it, are all but neutral in terms of their consequences on the economy, most notably on the distribution of resources among market participants. Thus, an inflation targeting central bank is as political in its actions as a bank following a dual mandate, the only difference being that In the former case the political nature of monetary policy is concealed behind a technocratic curtain.
The deep justification of exclusive focus on price stability can only lie in the acceptance of a neoclassical platonic world in which powerless governments need to make no choice. Once we dismiss that platonic view, monetary policy acquires a political role, regardless of the mandate it is given. A dual mandate has the merit of making this choice explicit, and hence to dispel the technocratic illusion.
I am not saying there would be no issues with the adoption of a dual mandate. The institutional design should be carefully crafted, in order to ensure that independence is maintained, and accountability (currently very low indeed) is enhanced. What I am saying is that after seven years (and counting) of dismal economic performance, and faced with strong arguments in favour of a broader central bank mandate, EMU policy makers should be engaged in discussions at least as lively as the ones of their counterparts in Washington. And yet, all is quiet on this side of the ocean… Circulez y a rien à voir
Paul Krugman raises the very important issue of the impact of monetary policy on financial stability. He starts with the well-known observation that, contrary to the predictions of some, expansionary monetary policy did not lead to inflation during the current crisis. He then continues arguing that tighter monetary policy would not necessarily guarantee financial stability either. If the Fed were to revert to a more standard Taylor rule, financial stability would not follow. As Krugman aptly argues, “That rule was devised to produce stable inflation; it would be a miracle, a benefaction from the gods, if that rule just happened to also be exactly what we need to avoid bubbles.“
Krugman in fact takes position against the “conventional wisdom”, which has been widespread in academic and policy circles alike, that a link exists between financial and price stability; therefore the central bank can always keep in check financial instability by setting an appropriate inflation target.
The global financial crisis is a clear example of the fallacy of this conventional wisdom, as financial instability built up in a period of great moderation. A recent analysis by Blot et al shows that the crisis is no exception, as over the past few decades, in the US and the Eurozone, the link between price and financial stability has been unclear and moreover unstable over time, as shown on the following figure.
We therefore subscribe to Krugman’s view that financial stability should be targeted by combining macro- and micro-prudential policies, and that inflation targeting is largely insufficient. In another work, Blot et al argue that the ECB should be endowed with a triple mandate for financial and macroeconomic stability, along with price stability. They further argue that the ECB should be given the instruments to effectively pursue these three, sometimes conflicting objectives.
Two articles on today’s Financial Times puzzle me. The first (Weidmann warns of currency war risk) offers yet another example of how economic analysis sometimes leaves the way to ideological beliefs. The Bundesbank’s president argues (as he already did in the past) that giving up inflation targeting hampers central bank independence. How? Why? He does not bother explaining.
What I think he has in mind is that once the objective of the central bank goes beyond strict inflation targeting, monetary policy needs an arbitrage between often conflicting objectives (typically unemployment and inflation). It is the essence of the dual mandate. This of course moves monetary policy out of the realm of technocratic choice, and makes it a political institution (Stephen King explains it nicely). I would argue that this is normal once we abandon the ideal-type of frictionless neoclassical economics, and we accept that we may have a tradeoff between inflation and unemployment. But this is not the issue here. The issue, and the puzzle, is why transforming the choice from technocratic to political, should necessarily lead to giving up independence. Read more
