We can always count on Robert Samuelson to give us some economic misinformation on Monday morning and he didn't let us down this week. In a very balanced column (yes, many tons of sarcasm here) decrying the economic proposals of both Donald Trump and Hillary Clinton he told readers: "The United States runs chronic trade deficits because the dollar serves as the main global currency. This raises its exchange rate, putting U.S. manufacturers at a disadvantage." This is wrong at just about every level. First, there are multiple reserve currencies, not just dollars. And, they trade frequently against each other, so there is a limit to how much the dollar will rise relative to the euro, yen, or pound because it is the main reserve currency. So, that is not the biggest part of the story of the trade deficit. The more important part of the story is that countries are holding much larger reserves relative to their GDP now than they did in the years prior to the East Asian financial crisis in 1997. This is due to the harsh terms of the bailout imposed by the Clinton administration through the I.M.F. As a result of these terms, virtually every country in the developing world in a position to do so began accumulating massive amounts of foreign reserves. This was to avoid ever having to be in the same situation as the East Asian countries and have to rely on the I.M.F. for help. The result was that instead of being net importers of capital from rich countries and running trade deficits, as standard economic theory would predict, developing countries became large exporters of capital running trade surpluses with rich countries. This was the origin of the "global savings glut" and secular stagnation that many prominent economists have complained about in recent years. This is all worth mentioning in the context of the rest of Samuelson's piece since he seems obsessed with the idea that we face inadequate supply when the economy's problem is quite obviously one of inadequate demand. In other words, he is recommending that someone on the edge of starvation go on a diet. His complaint about Hillary Clinton's proposals to expand Social Security and pay for college tuition for poor and middle-class children is that we don't have enough money. The whole story of secular stagnation is that we aren't spending enough money.

The NYT had its second major article in less than a month on the alleged mistreatment of a small public pension fund by the California Public Employee Retirement System (Calpers). The focus of this piece is the bill that the small California town of Loyalton faces from terminating its pension plan for four retirees and converting to a 401(k) system. According to the piece, the city council apparently did not understand the information Calpers gave it on termination costs when it voted in 2012 to end its pension with Calpers. This is unfortunate, but it is not clear that the council’s confusion is an appropriate topic for a major NYT piece.

The prior piece discussed problems involving pensions for six workers for Citrus Pest Control District No. 2. They discovered that there would be substantial costs associated with terminating their participation in Calpers and switching to a 401(k) pension. While that piece, like this one, implied that Calpers has been doing something improper; in fact, the system has provided all the appropriate information to its participants. 

It is certainly plausible that these very small systems with no professional administrators may not understand the information given to them by Calpers. In this case, the problem is a lack of sophistication on the part of the people managing these small funds, not Calpers.

Of course, this is the argument as to why a defined benefit system like Calpers is better than a 401(k) type system where individuals have to make their own investment decisions. Most people are not financially sophisticated. As a result they often make bad choices in managing their money. This is especially likely when people pushing various funds are in a position to make large fees by promoting bad choices.

It is striking that the NYT has now devoted a large amount of space to the problems facing a total of ten workers in the California Public Employees Retirement System. It might be appropriate for it to shift its focus to the tens of millions of workers without adequate retirement plans.

The Washington Post-Peter Peterson Austerity Tax

By Dean Baker and Lara Merling There have been several efforts by the media and various organizations funded by the Peter G. Peterson Foundation to highlight projected shortfalls in the Social Security trust fund in the context of the presidential campaign. They have argued that candidates should be proposing plans to deal with these shortfalls and in particular that these plans should include cuts to Social Security. Implicitly, or sometimes explicitly, they have argued that the projected tax increases needed to maintain full funding for the program would be too large a burden on taxpayers and the economy. In this context, it is worth remembering that the economy’s output has fallen sharply relative to the levels projected before the downturn in 2008–2009. If the economy had grown as was projected by the Congressional Budget Office in 2008, it would be more than 10.5 percent larger (almost $2 trillion) than it is today. This lost output comes to more than $6,200 per person for every man, women, and child in the country. The exact cause of this loss in output is not easy to determine. Usually the economy bounces back from a recession and more or less returns to its trend path of growth. That didn’t happen with this recession. A main reason it didn’t bounce back is that there was no source of demand to replace the demand generated by the housing bubble. The bubble led to a massive boom in construction. It also caused consumption to jump as people spent based on their bubble generated housing wealth.

The line that large numbers of people are out of work or seeing declining wages due to the wonders of new technology is really popular among pundits and elite-types. If technology is the culprit then we can all wring our hands and say how unfortunate it is that we have these losers, but it means that the folks on top are not to blame. After all, we aren't going to blame the Steve Jobs or Elon Musks of the world for their great innovations. For this reason, it is understandable that news outlets owned by rich people would endlessly promote this line even though it is utter nonsense with no basis in reality. Yet one more piece in this genre is a column by Ryan Avent in the Guardian. The column is taken from his new book, "The Wealth of Humans", which touts the great developments in technology in recent years. The column sees large numbers of workers being displaced by technology, leading to wide-scale unemployment. The obvious problem with this argument for those in the reality-based community is that it is a story of massive unemployment due to rapid productivity growth. But we haven't seen rapid productivity growth in recent years. In fact, productivity growth has averaged just 1.0 percent annually over the last decade. That compares to a rate of almost 3.0 percent in the decade from 1995 and 2005 and the quarter century from 1947–1973. Year over Year Change in Productivity Source: Bureau of Labor Statistics. So what we are seeing here is a continuing effort to misrepresent the nature of the problem of unemployment with something which clearly cannot offer a plausible explanation. If productivity growth is very slow then it doesn't make sense to argue that people are losing their jobs because of rapid productivity growth.

The NYT printed a column by Arthur Brooks which beautifully displayed how political elites misunderstand the appeal of Donald Trump. The piece, which is titled “those who don’t understand Trump are doomed to repeat them,” complained that many people see Trump’s rise as meaning, “that mainstream positions on issues such as trade and immigration must be fundamentally rethought.”

Brooks goes on to assert:

“The real issue is weak, unevenly shared growth. If we addressed this issue, and if people felt their lives improving, the appetite for invective on secondary issues such as trade and immigration would dissipate. So walking away from free enterprise principles on trade and immigration is not the solution.”

While the real issue is in fact unevenly shared growth, the fact is that we have not been following “free enterprise” principles on trade and immigration. Longer and stronger patent and copyright protections, which are the equivalent of tariffs of several thousand percent, are not “free enterprise.” Nor is a licensing system which prevents foreign trained doctors from practicing in the United States unless they complete a residency program in the United States part of most definitions of “free enterprise.” (Dentists have to complete a dental school in the U.S., although recently graduates of Canadian schools were also allowed to practice here.)

As a result of patent and related protections for prescription drugs we will pay more than $440 billion for drugs that would likely sell for around 10 percent of this price in a free market. The difference of close to $400 billion a year is more than five times the amount that we spend on food stamps and twenty times the amount that we spend on TANF. The “doctor tax” that we pay as a result of protectionism is close $100 billion annually. This is the difference between what we pay for doctors in the U.S. and what we would spend if our doctors were paid the same as doctors in Germany, Canada, or other wealthy countries.

These and other forms of protectionism are responsible for “unevenly shared growth.” The Trumpites will thrive both as long as such protections persist and even more so as long as our elites pretend that they are just the free market. This is of course the point of my new book, Rigged: How Globalization and the Rules of the Market Economy Were Structured to Make the Rich Richer.

The Brexit vote was a case where the elites were clearly aligned against the U.K. leaving the European Union. While they had many good arguments on their side, and much of what the pro-Brexit crew was saying was nonsense, some of the elite gloating now also falls into the nonsense category.

In particular, the fall in the British pound is being taken as evidence that Brexit was a mistake. Actually, this is not really evidence of anything. The pound had become seriously over-valued in recent years causing the U.K. to run a current account deficit that is projected to be almost 6.0 percent of GDP for 2016. This is almost certainly not sustainable. The current account deficit also leads to a large gap in demand, which at the moment appears to be filled primarily by demand generated by a housing bubble.

Note that this is an economic quagmire created by the British elite: the establishment folks running the Bank of England and the Treasury Department. The Brexiters had nothing to do with it.

The correction for an excessive current account deficit is a fall in the value of the currency, which the U.K. is seeing now. Rather than being a negative for the economy, this is a positive development. It is the only plausible mechanism through which the U.K. can get closer to balanced trade. While the decline has undoubtedly been hastened by fears over Brexit, the bigger problem was letting the pound get so over-valued in the first place.

It is also worth noting that if the value of the pound is measured relative to the euro rather than the dollar, which is arguably the more appropriate yardstick, the pound has not fallen that sharply. It is still well above the lows it hit relative to the euro in 2008 and 2009.

As the U.K. loses part of its financial industry in the fallout from Brexit, it will need increased output in other areas to fill the gap created. A lower-valued pound would be an important part of this story. A lower-valued pound will make a wide range of U.K. produced goods and services more competitive internationally, reducing the size of the country’s trade deficit.

The long and short is that anyone who thinks the falling pound is the best evidence of the foolishness of Brexit doesn’t have a very good argument for their position.

Okay, that’s not exactly what this piece on trade as a way to promote world peace said, but it is a logical implication. The piece was presenting the argument that free trade is a way to promote world peace since countries that trade with each other don’t want war to get in the way of their prosperity.

Of course if we accept this argument, then it can’t possibly make sense to claim that protectionist measures that some groups like are okay. So the protectionist measure that prohibits foreign doctors from practicing in the United States unless they complete a U.S. residency program is an obstacle to world peace. The same applies to the ban on foreign dentists who have not completed a dental program in the U.S., or in recent years, Canada as well. In the same vein, patent and copyright protections, which can be equivalent to tariffs of many thousand percent, should also be seen as major barriers to world peace.

After all, no one has made the argument that a protectionist barrier does not threaten world peace if rich people like it, although a Nobel prize in economics probably awaits anyone who does make this case.

By Dawn Niederhauser My name is Dawn Niederhauser, and I am the Director of Development for the Center for Economic and Policy Research. You may have received some emails from me in the past (OK I never signed them, but if you were asked to donate, well, that was me). This time I am writing to you directly because I have some exciting news — and I want to make you an offer that I hope you won’t be able to refuse. The exciting news first: CEPR’s Co-Director Dean Baker has written a new book! Titled Rigged: How Globalization and the Rules of the Modern Economy Were Structured to Make the Rich Richer, the book looks at the various ways in which the elites rig the game to ensure that income flows upward. It also offers policy prescriptions that would serve to reverse this trend. Early blurbs are glowing:  "This is an important and compelling book about how the rules governing the American economy have been rigged in favor of those with the wealth and political clout to rig them. Baker shows why and how the nation's staggering inequality has been the consequence of staggeringly unequal political influence.” writes Robert B. Reich, while Katrina vanden Heuvel of The Nation says “Dean Baker’s timely book Rigged is a must-read for the many who believe the status quo is unsustainable."

The Washington Post gave a column to Robert Rubin, the man best known for setting the U.S. economy on a path of bubble-driven growth in the late 1990s, the opportunity to share his wisdom on the economy. Unsurprisingly, Rubin proposes to cut Social Security and Medicare, as he has in times past. Of course, Rubin is not likely to need these programs since he earned over $100 million in his stint at Citigroup in the housing bubble years. The Financial Crisis Inquiry Commission recommended that the Justice Department investigate Rubin’s conduct at Citigroup during this period but for some reason it seems the Justice Department did not follow through.

Donald Trump, Economic Theory, and Trade Deficits

The desire to beat up on Donald Trump is understandable, but it is important to realize that not everything he says is wrong. For example, according to press accounts he adheres to the belief that the world is round.

Anyhow, Greg Ip goes a bit overboard in a Wall Street Journal piece where he argues that Trump’s claim that a trade deficit can be reduced or eliminated with tariffs is wrong. Referring to Trump’s approach to the trade deficit, Ip tells readers:

“But that is out of step with standard economics, which predicts that a country’s trade balance is determined by the gap between what it invests and saves, not by tariffs.”

As an accounting identity a country’s trade balance is always equal to the gap between what it invests and what it saves. This means that if the U.S. invests $200 billion a year more than it saves, then it will by definition be true that it has a trade deficit of $200 billion.

However, this accounting identity tells us nothing about causation. If we are below the full employment level of output, and Donald Trump’s tariffs or threats of tariffs, reduce our annual trade deficit by $200 billion (@ 1.1 percent of GDP), then this would lead to additional employment, output, and savings in the United States. A standard multiplier would suggest that a $200 billion reduction in the size of the trade deficit would lead to a $300 billion increase in GDP. This higher GDP would lead to more corporate and individual savings, as well as more tax revenue, which also count as savings. (The growth in GDP would also led to more imports, partially offsetting the initial improvement in the trade deficit.)

In other words, it is totally possible to reduce the size of the trade deficit as long as the economy is below its full employment-level of output. This is basic economic theory. Folks should be clear on this point, even if it suggests that Trump might be partly right on something.
