Martin Feldstein says there are good reasons for the difference in monetary
policy between the Fed and the ECB, the most important being that unions are
stronger in Europe than the US. This means there is a greater chance of a
wage-price spiral developing in Europe forcing the ECB to adopt a tougher stance on
inflation:
The crisis: a tale of two monetary policies, by Martin Feldstein, Commentary,
Financial Times: The European Central Bank and the Federal Reserve are
facing similar problems but pursuing different policies. The ECB has been
raising interest rates while the Fed has been cutting them. ... Which central
bank is doing the right thing? Or could they both be?
Inflation is a significant problem in both the eurozone and the US... Both
economies are also facing declining economic activity with falling employment...
The sharp rise in the prices of energy and food ... will undoubtedly spill over into higher prices... The primary challenge for both central banks is to limit this inflationary shock
to a one-time pass through, avoiding the ... wage-price spiral that drove
inflation rates in the 1970s to double-digit levels. Preventing a repetition of
that requires convincing the public that today’s high inflation rate will soon
decline.
Despite the similar problems faced by the two central banks, there are
important differences that justify their separate strategies. The contrast
between the ECB’s mandate to achieve price stability and the Fed’s “dual
mandate” to balance the goals of price stability and employment is ... a reflection of fundamental differences
between the two economies. Those differences make it more difficult to tame
inflation expectations in Europe and therefore require the ECB’s tougher policy.
The role of trade unions is the most important difference. Only 7.5 per cent
of US private sector employees are union members... In contrast, more than 25
per cent of employees in the European Union are members of trade unions and in
some EU countries the wages set in union contracts are automatically extended to
other companies in the same industry.
Because of this union power, the ECB must persuade union members and their
leaders that it is determined to bring inflation down to its target level... The
ECB’s tough stance and exclusive emphasis on price stability is crucial to
shifting inflation expectations and persuading unions to accept the rise in food
and energy prices without pressing for offsetting wage gains.
In contrast, the Fed does not have to worry in the same way about union power... Wage setting is decentralised and wage contracts do
not have the formal links of wages to inflation that intensified the wage-price
spiral of the 1970s.
Differences in the inflation histories also influence today’s appropriate
policies of the ECB and the Fed. Although Americans remember the double-digit
inflation of the late 1970s and early 1980s, there has been no US experience
similar to the earlier hyperinflations in Germany and other EU countries. The
ECB pursues a tough inflation target policy to persuade Europeans that there is
not even a small probability of returning to those conditions.
Finally, the ECB recognises that it is still a very young institution that
must prove ... that it will follow the successful
anti-inflation tradition of the German Bundesbank. ... The ECB is only now
facing its first challenge of imported high inflation...
The power of Europe’s unions, its history of hyperinflation and the need to
develop credibility for a young institution all justify the ECB’s tough stance.
Because the Fed does not have these problems but faces a potentially serious
recession, it is prepared to gamble that the weakness in US employment and the
general decline in economic activity will prevent a wage-price spiral without
further increases in the interest rate. ... I think the Fed’s current interest
rate strategy makes sense but would be too risky for the ECB.
There's
another hypothesis that says the reason the ECB is able to focus more on
inflation is because of the stronger social safety net that is in place in
Europe relative to the US. With a stronger social safety net, variations in
employment are less costly and that allows more focus on inflation.
I don't think either explanation gets at the essential reason for the
difference in strategies among central banks with some more committed to
inflation fighting than others, at least in their official pronouncements.
If you look at the history of who adopted inflation targets first, you will
see that the order was New Zealand, Chile, Canada, UK, Sweden, Australia,
Norway, Brazil, Hungary, Poland, Mexico, and the Czech Republic (I may not have
the order exactly right,
source), and the move to inflation targets was largely driven by a desire
for more central bank independence. When monetary policy is in the hands of
elected officials, the result tends to be high rates of inflation. There is a
tendency for elected officials to print new money to pay for government spending
rather than using politically more explosive means such as increasing in taxes,
cutting spending, or increasing government debt, and this leads to high rates
of inflation. Moving from government control over the money supply to an
independent central bank dedicated to long-term objectives is a way to solve
this problem, but there is a need for the new institution to be credible. That's
where explicit inflation targets come in. They are a transparent way of
committing to a target, and this allows the credibility of the monetary authority to be easily
assessed.
There may be a correlation between high degrees of unionization and highly
interventionist governments that is driven by societal preferences for, say, a
strong social safety net for workers. And highly interventionist governments
may, if they can get their hands on monetary policy, tend to be inflationary.
But it's not the unions that are the problem, the problem is the lack of an
independent monetary authority and lack of commitment (or lack of ability to
commit) to long-run price stability goals. Countries that have moved to a more
independent central bank with transparent inflation goals have experienced lower
inflation rates even when they have high degrees of unionization. It was the
desire for an independent monetary authority and the need to establish
credibility that led to the difference in emphasis on inflation and output
between the US, which already had a relatively independent and credible central
bank, and other central banks around the world.
Finally, it is misleading, I think, to characterize the ECB as strict
inflation targeters, "inflation nutters" to use Mervyn King's term for it.
Output targets remain important. First, in the short-run, inflation targeting
central banks will allow inflation to move outside the target range if they are
worried about weakness in output and employment. Second, an inflation target
above zero, say 2%, recognizes the potentially destructive effect of deflation
on output (a reason why many people have urged the Bank of Japan to adopt an inflation target above
zero - deflation has been a problem for the Japanese economy). Thus, output is
clearly part of the central banks' objective function. Third, well, let me quote
Bernanke:
Several authors have made the distinction between so-called "strict"
inflation targeting, in which the only objective of the central bank is price
stability, and "flexible" inflation targeting, which allows attention to output
and employment as well. In the early days of inflation targeting, this
distinction may have been a useful one, as a number of inflation-targeting
central banks talked the language of strict inflation targeting and one or two
came close to actually practicing it. For quite a few years now, however, strict
inflation targeting has been without significant practical relevance. In
particular, I am not aware of any real-world central bank (the language of its
mandate notwithstanding) that does not treat the stabilization of employment and
output as an important policy objective. ... Moreover, virtually all (I am
tempted to say "all") recent research on inflation targeting takes for granted
that stabilization of output and employment is an important policy objective of
the central bank. In short, in both theory and practice, today all inflation
targeting is of the flexible variety.
I don't disagree that unions can magnify inflation pressures and give inflation
more inertia, but the answer to the inflation problem is an independent,
credible central bank. Without that, inflation is likely to be a problem whether
strong unions are present or not.
