The Coming Crisis: the monetary policy credibility trap

More recent proposals include helicoptering money into the government’s or the public’s accounts, abolishing cash to make low interest rates effective, and even introducing a reverse incomes policy – a government-enforced increase in wages (as opposed to the wage controls of the 1970s) to try to get inflation going.

All of these existing and potential policies break with current economic norms, and all are being pitched as temporary, exceptional measures that are (or may be) necessary in the face of an extreme crisis.

Ironically, rule-following was designed precisely to avoid this problem. It came into its own as an influential approach to monetary policy in the wake of the destabilizing 1970s, with their stop-go economic policies and rampant inflation. Mainstream economists came to love rule-based monetary policy as did politicians – not just neoconservatives like Margaret Thatcher and Ronald Reagan who first championed the approach, but eventually the more centrist politicians who followed like Tony Blair and Bill Clinton, as well as today’s mixed lot.

A rule-governed approach to policy was designed to be both politically and economically stabilizing – to do away with the problem and even the possibility of exceptions by removing not only governments’ but even central bankers’ discretion: just stick to the rule, and everything will work out. A tidy, efficient, depoliticized (although certainly not apolitical) approach to monetary policy.

Yet rules only seem great until they don’t apply anymore. A rule that pretends it can always apply (or at least, as Colin Hay puts it in his introductory blog, in the 99.9% of times that seem relevant) inevitably runs serious problems when an exception becomes necessary.

Of course, as Alan Greenspan has noted, the victory of rules over discretion was never entirely true in practice. But it was an extremely powerful narrative – one that promised that the commitment of central banks (and governments) to low inflation and economic stability was credible because they were constrained to follow the rules.

It was also a very effective narrative that has convinced markets that anything other that rule-following is likely to be destabilizing. As central banks begin to face the limits of those rules, their earlier persuasiveness has come back to haunt them: a recent paper from some Federal Reserve staff notes that although a higher inflation target would make sense in the United States, increasing it could well backfire if market actors believed that it would be too inflationary.

This fixation on rule-following has thus put central bankers into a credibility trap. If bankers admit that the rules no longer apply, then they risk losing their credibility as market actors have come to believe the mantra that rules – particularly low inflation targets – are the only way to ensure sound monetary policy. On the other hand if they don’t admit the limits of the rules, and continue lurching from exception to exception, they will eventually lose credibility as the gap between rhetoric and reality widens.

Central banks are damned if they do admit the limits of rules and damned if they don’t.

Of course, the most viable solution to this trap is for governments to stop relying so heavily on central banks in the first place and start taking some responsibility for economic recovery through concerted fiscal action (something that the Canadian government has at least started to do). Yet for that kind of fiscal action to work, governments have to convince the markets that they believe in it enough to stick to their guns and follow through – a rather unlikely scenario in today’s austerity-driven times.

As the potential for renewed economic crisis continues to grow, this credibility trap will only widen – as central bankers and governments find themselves lurching from exception to exception, refusing to question the neoliberal rules that no longer seem to apply.
