Time to put the brakes on this runaway train
Kenneth Rogoff

THE global economy is a runaway train that is slowing, but not quickly enough. That is what the extraordinary run-up in prices for oil, metals, and food is screaming at us.

The spectacular and historic global economic boom of the past six years is
about to hit a wall. Unfortunately, no one, certainly not in Asia or the US, seems willing to bite the bullet and help engineer the necessary co-ordinated retreat to sustained sub-trend growth, which is necessary so that new commodity supplies and alternatives can catch up.

Instead, governments are clawing to stretch out unsustainable booms, further pushing up commodity prices, and raising the risk of a once-in-a-lifetime economic and financial mess. All this need not end horribly, but policy makers in most regions have to start pressing hard on the brakes, not the accelerator.

Don’t look to the US for leadership in a presidential election year. On the contrary, the US government has been handing out tax-rebate cheques so that Americans will shop until they drop .

Don’t look to emerging markets, either. Desperate to sustain their political and economic momentum, most have taken a wide variety of steps to prevent their economies from feeling the full brunt of the commodity price hikes. As a result, higher commodity prices are eating into fiscal cushions rather than curtailing demand.

I am puzzled that so many economic pundits seem to think that the solution is
for all governments, rich and poor, to pass out even more cheques and subsidies so as to keep the boom going. Keynesian stimulus policies might help ease the pain a bit for individual countries acting in isolation. But if every country tries to stimulate consumption at the same time, it won’t work. A general rise in global demand will simply spill over into higher commodity prices, with little helpful effect on consumption. Isn’t this obvious? Yes, there is still a financial crisis in the US, but stoking inflation is an incredibly unfair and inefficient way to deal with it.

Some central bankers tell us not to worry, because they will be much more disciplined than central banks were in the 1970 s, when the world faced a similar commodity price spike. But this time is different. The commodity price problem has sneaked up on us, despite notable institutional reforms in macroeconomic policy-making all over the world.

The historic influx of new entrants into the global workforce, each aspiring to western consumption standards, is simply pushing global growth past the safety marker on the speed dial. As a result, commodity resource constraints that we once expected to face in the middle of the 21st century are hitting us today.

Wait a second, you say. Why can’t our market economies roll with the punches? Won’t high prices cause people to conserve on consumption and seek out new sources of supply? Yes, and that eventually happened with energy supplies in the 1980s. But the process takes time, and, because of the rising weight of relatively inflexible emerging market economies in global consumption, adjustment will probably take longer than it did a few decades ago.

Rich country consumers are responding to higher energy prices, and it helps. New York City, for example, has seen a reduction of perhaps 5% in private vehicles entering the city over the past six months. Gridlock has abated, and you can almost get around the city by car these days.

But the response is slower elsewhere. It certainly is not getting any easier to drive around in places such as Sao Paulo, Dubai, and Shanghai. For a variety of reasons, mostly related to government intervention, few emerging market economies can be categorised as having flexible resource demand, so commodity price spikes are not having a particularly big effect on demand.

The central bankers who tell us not to worry about inflation point to relative wage stability. Expansions usually start collapsing when labour gets too scarce and too expensive. But the current expansion is unusual in that, due to unique (in the modern era) circumstances, labour constraints are not the problem. On the contrary, the effective global labour force keeps swelling.

No, this time, commodity resources are the primary constraint, rather than a secondary problem, as in the past. That is why commodity prices will just keep soaring until world growth slows down long enough for new supply and new conservation options to catch up with demand.

This runaway-train global economy has all the hallmarks of a giant crisis in the making — financial, political, and economic. Will policy makers find a way to achieve the necessary international
co-ordination? Getting the diagnosis right
is the place to start. The world as a whole needs tighter monetary and fiscal policy. It is time to put the brakes on this runaway train before it is too late. Project Syndicate, 2008. www.project-syndicate.org.

Interessantissimo articolo.

Bell'articolo, soprattutto la parte sottolineata.
La recessione paradossalmente è l'unica salvezza.

Io però mi stupisco che Rogoff si stupisca, i cantori della spesa pubblica e della politica monetaria allegra ci sono sempre stati e sempre ci saranno.
A parte questo ottima analisi e grazie a Feliks per averla postata.
