Sometime back around 2000 or 2001, I recall reading a friendly debate in the Irish press between Nobel economists and fellow ‘Chicago School’ heavyweights Robert Mundell and Milton Friedman. In it, Mundell referred to a tenet of Friedman’s as "stupid". It certainly wasn’t because he thought Friedman was lacking in intelligence. Rather, it stemmed from frustration that someone as smart as Friedman could believe something that in Mundell’s view made absolutely no sense. Now I’m certainly no intellectual heavyweight, and I don’t know that Paul McCulley of PIMCO would hold himself out as one either. But after reading his recent missive–by way of John Mauldin’s website–I at least know how it feels to think that someone smart is being awfully stupid.
McCulley argues that a dovish monetary policy stance is required to counter a "real terms of trade shock". By that, he means that the U.S. has to work harder to acquire the same goods and services in trade; in other words, a unit of U.S. labor commands fewer goods and services in international trade than it did a few years ago. The example he cites is the cost of a barrel of oil in terms of hours worked, which has gone up nearly seven fold since 2003. He asserts that when such a shock occurs, a central bank must pursue a course of negative real interest rates** in order to prevent recession, or worse, depression. To which we can only say, "…Wow!"
Can a negative real interest rate ease some of the pain associated with a negative terms of trade shock? It can certainly soften the blow. But what are the long term costs? More importantly, what’s the effect when the proximate cause of the trade shock (higher oil prices, in this case) is NEGATIVE REAL INTEREST RATES themselves? Look at the trajectories of oil and other commodity prices when real central bank rates are negative, near zero, or positive, and the effects are quite clear. In the 1970s, real interest rates were negative before oil and commodity prices took off. They were very high before oil and commodity prices began a twenty year descent in the 1980s. And they were negative again beginning in 2003, when the current oil and commodity price boom began.
McCulley tries to work around this by claiming that the U.S. economy was more closed in the 1970s, and thus more prone to a wage driven inflationary spiral. That may be true (though in our view stagflation cannot occur in a closed economy, leading us to believe that globalization was an important factor in the 1970s). But for all intents and purposes, and in the immortal words of Bill Murray’s Tripper Harrison, "it just doesn’t matter!". The issue at hand is how well the rate on a new unit of money aligns with the marginal rate on USD supported investment, wherever those marginal investments may lie–Dubuque, Crested Butte, New York City, Dublin, Singapore, Prague, Swaziland, Shanghai, Timbuktu, or wherever else–anywhere that USD reserves can be used to finance investment***.
So what happens when the Fed, in supporting the domestic economy, primes the monetary pump by keeping interest rates very low? It simply drives up investment in those parts of the world that are expected to grow fastest, and where said growth can be financed with US dollars, whether directly or indirectly. And the resulting overheating makes certain goods more expensive for everybody, even countries experiencing a major slowdown like the U.S. recently has. Combine the resulting inflation with an already high U.S. corporate tax rate and an expected capital gains rate hike and you have a recipe for domestic stagflation. But hey, it sure beats a depression (actually, that case can be made based on the historical data, at least over short to intermediate periods).
One thing that we agree with McCulley on is that a less inflationary monetary policy would mean more economic pain at home, assuming nothing elses changes. But McCulley’s proposed "solution" is likely to cause more long term damage than it’s worth. A serious decline in investment, chasing away productive, mobile assets like human and financial capital, and undermining the international credibility of its money are first steps on the road to any civilization’s decline. And in the case of the U.S., another crisis of confidence in the U.S. dollar, like the one that occurred from the 1960s to the 1980s, could impose huge long term costs on us, given that there is finally a legitimate contender in the Euro that could further diminish the role of the USD as sole international reserve currency. That was definitely not the case in the 1970s, however closed or open the U.S. economy might have been.
So what can U.S. policymakers do to improve the real terms of trade, without imposing deflation and/or recession or depression? We’ve said it often, and we’ll say it again because it bears frequent repeating–it’s the policy mix, "stupid". Mundell articulated the right mix way back in 1961 while he was an economist at the IMF: lower the disincentives to activity in the real economy, and equalize the incentive to hold or invest US dollars, and both stagnation and inflation will recede.
The right policy mix ain’t gonna happen any time soon, unfortunately, and ideas like McCulley’s are going to hold center stage for a few more years, I’m afraid. But eventually the U.S. electorate will relearn the same old lesson: lower taxes and sounder money are the cure for both inflations and recessions. Hopefully its fearless leaders will catch on after awhile and follow.
** When a central bank’s target interest rate is negative, it means that dollars are expected to be worth less in the future than they are today; it is expected that such a condition induces people to spend and invest more today than they otherwise would.
*** We haven’t actually checked into how much USD driven finance occurs in all of those locales. They’re meant to be illustrative and, we hope, a little poetic.
