What's causing the trade deficit?
Gosh darn it, if part of being a transatlantic fellow for the German Marshall Fund of the United States means going to northern Italy for the rest of this mid-June week to try and promote greater transatlantic understanding, then I have no choice but to do my duty. Blogging could be erratic over the next few days.
Talk amongst yourselves. Here's a topic -- is the a massive current account deficit a function of the sizeable budget deficit, the low U.S. savings rate, currency manipulation, or a global savings glut?
The global savings glut argument has been advanced by Ben Bernanke, who is likely to be the next Fed chairman. A quick precis of his argument: I will take issue with the common view that the recent deterioration in the U.S. current account primarily reflects economic policies and other economic developments within the United States itself. Although domestic developments have certainly played a role, I will argue that a satisfying explanation of the recent upward climb of the U.S. current account deficit requires a global perspective that more fully takes into account events outside the United States. To be more specific, I will argue that over the past decade a combination of diverse forces has created a significant increase in the global supply of saving--a global saving glut--which helps to explain both the increase in the U.S. current account deficit and the relatively low level of long-term real interest rates in the world today....
[S]pecific trade-related factors cannot explain either the magnitude of the U.S. current account imbalance or its recent sharp rise. Rather, the U.S. trade balance is the tail of the dog; for the most part, it has been passively determined by foreign and domestic incomes, asset prices, interest rates, and exchange rates, which are themselves in turn the products of more fundamental driving forces. Instead, an alternative perspective on the current account appears likely to be more useful for explaining recent developments. This second perspective focuses on international financial flows and the basic fact that a country's saving and investment need not be equal in each period....
That inadequate U.S. national saving is the source of the current account deficit must be true at some level; indeed, the statement is almost a tautology. However, linking current-account developments to the decline in saving begs the question of why U.S. saving has declined. In particular, although the decline in U.S. saving may reflect changes in household behavior or economic policy in the United States, it may also be in some part a reaction to events external to the United States--a hypothesis that I will propose and defend momentarily.
One popular argument for the "made in the U.S.A." explanation of declining national saving and the rising current account deficit focuses on the burgeoning U.S. federal budget deficit, which in 2004 drained more than $400 billion from the national saving pool. I will discuss the link between the budget deficit and the current account deficit in more detail later. Here I simply note that the so-called twin-deficits hypothesis, that government budget deficits cause current account deficits, does not account for the fact that the U.S. external deficit expanded by about $300 billion between 1996 and 2000, a period during which the federal budget was in surplus and projected to remain so. Nor, for that matter, does the twin-deficits hypothesis shed any light on why a number of major countries, including Germany and Japan, continue to run large current account surpluses despite government budget deficits that are similar in size (as a share of GDP) to that of the United States. It seems unlikely, therefore, that changes in the U.S. government budget position can entirely explain the behavior of the U.S. current account over the past decade....
The weakening of new capital investment after the drop in equity prices did not much change the net effect of the global saving glut on the U.S. current account. The transmission mechanism changed, however, as low real interest rates rather than high stock prices became a principal cause of lower U.S. saving. In particular, during the past few years, the key asset-price effects of the global saving glut appear to have occurred in the market for residential investment, as low mortgage rates have supported record levels of home construction and strong gains in housing prices.... The expansion of U.S. housing wealth, much of it easily accessible to households through cash-out refinancing and home equity lines of credit, has kept the U.S. national saving rate low--and indeed, together with the significant worsening of the federal budget outlook, helped to drive it lower. As U.S. business investment has recently begun a cyclical recovery while residential investment has remained strong, the domestic saving shortfall has continued to widen, implying a rise in the current account deficit and increasing dependence of the United States on capital inflows.
According to the story I have sketched thus far, events outside U.S. borders--such as the financial crises that induced emerging-market countries to switch from being international borrowers to international lenders--have played an important role in the evolution of the U.S. current account deficit, with transmission occurring primarily through endogenous changes in equity values, house prices, real interest rates, and the exchange value of the dollar.
Is Bernanke correct? This argument does jibe with recent research suggesting that reducing the budget deficit doesn't have a large impact on the trade deficit. However, for critiques of this argument, see Daniel Gross' link-rich essay in Slate, as well as cogent posts by Brad Setser and this post by Brad DeLong.
My take -- this isn't an either-or question. Bernanke identifies a cause that has been underplayed by administration critics, but Bernanke himself makes it clear that he thinks domestic factors also play a role.
Much more disconcerting is this section of Bernanke's speech:
There is another danger -- the encouragement of speculative investment in housing in the U.S. and elsewhere. See the New York Times' David Leonhardt and Motoko Rich, as well as the Economist, for more on this.posted by Dan on 06.21.05 at 12:46 PM
As Drezner is an offshoring advocate, I suppose he would argue that the fact that it's hard to buy anything at our largest retailers which is "Made in the U.S.A." has absolutely no connection our current account deficit.
Yeah right!posted by: camille roy on 06.21.05 at 12:46 PM [permalink]
Is this a trick question, Dan? Do you really think that the trade deficit could be caused by inadequate savings in the US compared to other countries? Among the possible explanations you list, you fail to mention the simple fact that Americans buy more foreign products and services than we sell because they're cheaper. And the Arabs, Indians, and Chinese have nowhere else to put the money except in the US bond market. In long run, of course, this trend will drive down the US dollar and help balance things out. But then, in the long run... how does that go?posted by: Larry on 06.21.05 at 12:46 PM [permalink]
Why, though, would you have a global savings glut at a point in time where large and relatively underdeveloped economies (China, India) have reached the takeoff point and need lots of capital investment internally? Isn't it rather bizarre that every spare $ China has isn't being spent on capital equipment rather than being invested in treasuries?posted by: David Foster on 06.21.05 at 12:46 PM [permalink]
How about none of the above? I'd say the reason for our current accounts balance is that the U. S. economy has undergone a fundamental shift (from producing goods to services) without the necessary shifts in foreign policy (enforcing intellectual property rights and gaining entry into overseas services markets).posted by: Dave Schuler on 06.21.05 at 12:46 PM [permalink]
Hi, Dan. I'm sorry for the OT comment, but I just had an experience about a half an hour ago that immediately made me think, "What would Dan say?"
I was sitting at an IHOP having lunch, and a guy in the booth across the aisle from mine fielded a call on his cell phone. In five minutes he had made an agreement to get a bid on outsourcing five customer service reps.
It was really astonishing. Normally outsourcing is pretty remote, I was surprised to have it served with a side of fries.
At the time he was speaking I had finished my lunch and had opened my laptop to take down an idea I had for my book. I had Notepad open, and I type pretty fast. Here's what he said. Amazing. It was all done in five minutes, no more.posted by: Lisa Williams on 06.21.05 at 12:46 PM [permalink]
In response to David Forester: I remember reading in the Economist (some time ago when there was a special secion on China. Ring a bell with anyone?)that China's savings rate was too high and that there was too much money chasing too few sound investments. And too little domestic demand for Chinese goods. The article warned that loose lending practices were creating overcapacity in many sectors and leaving Chinese banks with lots of non-performing loans in their portfolios. If this is true, it would make sense that, in China at any rate, there might not be enough capacity to soak up investment. I don't know about India. Of course, China's investment in American bonds is an intentional policy to keep the Yuan from slipping to allow their current trade surplus to continue and allow their economy to absorb rural-urban migration and workers from the rickety state sector.posted by: Ken on 06.21.05 at 12:46 PM [permalink]
The current trade deficit is a human thing.
Today we have 17 % of the workforce employed in the manufacturing sector as compared to 15, 20 years ago 25%. I say not enough domestic manufacturing jobs and domestic consumption to go along with it.posted by: ron on 06.21.05 at 12:46 PM [permalink]
I'm surprised that no one has mentioned the skyrocketing price of oil. We haven't reduced our consumption of imported oil (IIRC, its increased) even though the price has gone up considerably.
As for the nonsense about US Savings rates...what bollocks. Sure, if US consumers were spending less, they'd be spending less on imports --- but they'd also be spending less on domestically produced goods as well. If that happened, the US economy would go into another recession, which of course would translate in to further reduced demand for imported goods. In other words, the "savings" argument is nothing more than blaming the trade deficit on the "failure" of the US economy to be recessionary.....posted by: p.lukasiak on 06.21.05 at 12:46 PM [permalink]
When I read a post like this one, and there are many others quite similar, I am left with one thought.
He/she understands almost nothing about the effects of world trade policies and U.S. incentives for corporate interests to go offshore.
The bulk of such nonsense is little more than trying to find a way, any way, to avoid discussing the implications of trade policies and corporate-oriented incentives which create the conditions for most imbalances we are witnessing. The financing for many of the other imbalances would not exist if not for the growing U.S. trade deficit.
Dan states that "the U.S. trade balance is the tail of the dog" of U.S. current account problems. He has stated it exactly backwards.
Dream on, Dan. And keep looking for those excuses to not discuss the impacts of trade policy decisions.

From my perspective, a global savings glut couldn't possibly be the cause of our C/A deficit because the C/A deficit is ultimately a function of US demand. Surplus global savings don't create that demand, although they may facilitate it. It's not like US consumers got together and said, Hey, let's help out these poor schlubs with too much savings. On the contrary, they individually said, I want a new, e.g., flat panel TV and I don't have enough cash to buy one so I'll have to charge it. To the extent that a global savings glut lowers interest rates, thus stimulating US demand, you could argue that it causes the C/A deficit, but I think that's a stretch.posted by: CL McGhee on 06.21.05 at 12:46 PM [permalink]

Here's an old Wall St. Journal article I found interesting (sub'n req'd):
Forty-two percent of all U.S. trade in goods, $950 billion last year, occurs between arms of the same companies, including U.S.-based companies trading with their foreign divisions as well as foreign companies trading with their U.S. arms. Nearly 90% of U.S. imports from Ireland are such "related party" trade, as are 74.6% from Singapore, 62.1% from Germany and 61.1% from Mexico.
"When so much of trade is related-party moves, the determining driver is demand in the U.S., not shifts in exchange rates," says Joseph Quinlan, chief market strategist of global wealth and investment at Bank of America.
The so-called global savings glut is really a result of anti-growth policies in areas with lots of savings, such as Europe and Japan. Those savings cannot be productively invested locally so they come here.
While those areas had such problems before, globalization has made it easier for the under-utilized savings to come here for a better return.
Note that China has lots of savings too, but those are being locally invested. At least until now. China seems to be hitting a wall of export-driven growth, so it might start having problems with under-utilized savings such that those come here too.
Ideally the rest of the world would stop their stupid anti-growth games. But that won't happen. Their governments and ruling elites find domestic enonomic growth to be a threat to their power. In Europe, notably in France, much of the population agrees with the anti-growth polices.
Significant economic growth means change, and change is a threat to the status quo. Lots of interest groups, elites and sometimes a majority of the population prefer the status quo.
Until those economically irrational factors abroad are addressed, economically irrational things like our trade deficit will happen.

Oops, I meant that significant economic growth caused by domestic demand threatens the status quo, as opposed to economic growth driven by exports.
It's growth in domestic demand which threatens vested interests and such. Export driven growth is less threatening because it is easier to control.posted by: Tom Holsinger on 06.21.05 at 12:46 PM [permalink]
At its simplest, primal level, the trade policies of Bush/Clinton/Bush go something like this:
The US will encourage the destruction of millions of manufacturing jobs so we can all go to Wal-Mart and buy cheap underwear.
There is a trade deficit because we don't make much anymore, we gave those jobs away and threw the workers on the trash heap of history. After all, they are not part of the elite, so who cares?posted by: save_the_rustbelt on 06.21.05 at 12:46 PM [permalink]

"Economists, puzzled that a weaker dollar hasn't done more to shrink the U.S. trade deficit..."
Given that they have been puzzled by precisely this same combination for the past 25 years, I would suggest that either they invent some new facts or perhaps consider that their theories are better suited to a parallel universe.posted by: Gene on 06.21.05 at 12:46 PM [permalink]
actually, a weak $ at the end of the 80s/ early 90s did shrink the trade deficit, and a strong dollar at the end of the 90s led it to expand. right now, the dollar is only really weak against the euro -- it is strong against most emerging economies, and the global pattern of trade has changed in ways that make the euro/$ (and the pound/ dollar) less important in determining the us trade balance. throw in some changes in savings behavior in the us that offset the impact of a (not really) weak dollar, and i don't think the absence of a stronger trade response is all that much of a surprise.
one part of the WSJ argument is probably true -- with more trade between different parts of an MNC, the impact of XRs will come through the impact on MNC sourcing decisions, and that may introduce longer lags.
still, change the RMB/ $, and, after the standard two year lag and j-curve effects, i suspect the US trade deficit would be significantly lower than it would be without any change. markets work through adjustments in relative prices.posted by: brad on 06.21.05 at 12:46 PM [permalink]
