Trading volumes of the most-traded steel rebar contract in Shanghai hit a record 1.3bn tonnes today, or enough to build the Sydney Harbour Bridge 24,621 times.

If skyscrapers are the preferred metric, fret not: trades today were also equivalent to approximately 41,401 Burj Khalifas.

…One could construct around 178,082 Eiffel Towers with the above-mentioned volume of steel rebar traded today in Shanghai.

Here is the FT story.  Hat tip goes to the ever-excellent Christopher Balding.

In response to my post on transgender issues, I was sent this in an email, by a very good economist, it is lengthy so I am putting most of it under the fold, but do please read the whole thing.

First of all, I would like to thank you for contributing to this debate and for consistently sticking up for trans people and LGBT people more generally. We need more people like you who can engage in good, reasoned debate.

I would like to make a few observations in order to summarize this debate, and to use this summary to push for a fourth alternative–a sort of Hayekian alternative, which involves building upon the spontaneous order that we already have. This is assuming that there will always be a legal definition (or several overlapping definitions) of gender, ruling out option 1. Option 2 (overlapping definitions) is already a reality, which we can use to build on. Seen in that light, option 3 (the current debate) seems like a step backward, driven by emotions rather than reason.

A little background about me: I am one of three (to my knowledge) “out” trans* economists, and one of two “out” trans women. As such, I have followed the debate about trans* people since I was young, since this debate is about my very survival. In addition, I think that it is useful to look at this debate through the lens of economics and moral philosophy, since that lens helps us to see some of our blind spots.

Here is the AEA account, opening bit:

Yuliy Sannikov is a theorist who has developed new methods for analyzing continuous time dynamic games using stochastic calculus methods. His work has not only broken new ground in methodology, it has had a substantial influence on applied theory. He has significantly altered the toolbox available for studying dynamic games, and as a result of his contributions, new areas of economic inquiry have become tractable for rigorous theoretical analysis. The areas of application include the design of securities, contract theory, macroeconomics with financial frictions, market microstructure, and collusion.

Here is excellent coverage from A Fine Theorem, here is part of the opening bit:

The JBC has, in recent years, been tilted quite heavily toward applied empirical microeconomics, but the prize for Sannikov breaks that streak in striking fashion. Sannikov, it can be fairly said, is a mathematical genius and a high theorist of the first order. He is one of a very small number of people to win three gold medals at the International Math Olympiad – perhaps only Gabriel Carroll, another excellent young theorist, has an equally impressive mathematical background in his youth.

Sannikov is at Princeton…congratulations to him and them!

Global fishing stocks are collapsing due to the tragedy of the commons and the resulting overfishing. Technology, however, suggests a possible solution:

Global Fishing Watch is the product of a technology partnership between SkyTruth, Oceana, and Google that is designed to show all of the trackable fishing activity in the ocean….

The tool uses a global feed of vessel locations extracted from Automatic Identification System (AIS) tracking data collected by satellite, revealing the movement of vessels over time. The system automatically classifies the observed patterns of movement as either “fishing” or “non-fishing” activity.

This version of the Global Fishing Watch started with 3.7 billion data points, more than a terabyte of data from two years of satellite collection, covering the movements of 111,374 vessels during 2012 and 2013. We ran a behavioral classification model that we developed across this data set to identify when and where fishing behavior occurred. The prototype visualization contains 300 million AIS data points covering over 25,000 unique vessels. For the initial fishing activity map, the data is limited to 35 million detections from 3,125 vessels that we were able to independently verify were fishing vessels. Global Fishing Watch then displays fishing effort in terms of the number of hours each vessel spent engaged in fishing behavior, and puts it all on a map that anyone with a web browser will be able to explore.

Can vessels turn AIS off?

Sure, but that is certain to draw attention, like wearing a trenchcoat and sunglasses on a hot summer day. Global Fishing Watch will enable us to flag suspicious behaviors like suddenly disappearing, or appearing as if from nowhere, or jumping 1,000 miles and appearing to fish in the middle of Asia. It will give us the opportunity to identify who may have something to hide, and who is operating openly and transparently. Secondly, more countries and intergovernmental agencies like Regional Fisheries Management Organizations (RFMOs) are requiring AIS use within their waters, so more fishing vessels will be legally compelled to use AIS in the coming years. Many already are. For example, as of May 2014, all European Union-flagged fishing vessels over 15 meters in length are required to use AIS. Perhaps most importantly, AIS was primarily designed as a safety mechanism to help avoid collisions at sea. Turning off your AIS just to avoid being tracked puts your vessel and crew at risk of being run down by a cargo ship in the middle of the night.

Mark this as another example of the end of asymmetric information.

If I were writing a piece advocating Universal Basic Income, I would not call it “Why Free Money Beats Bullshit Jobs.”

That is from Rutger Bregman, though please note he may not have chosen the title.  I believe such a title would not appeal to the people who have…bullshit jobs…and who are being asked to finance the free money.

This economist so transparently pandering to Trump also will not convince.  And here an actual Satanist is not so convinced by some recent claims about Ted Cruz.

From a new Pew Study:

In our latest national political survey, released in March, 59% of the public say immigrants strengthen the country, while 33% describe them as a burden. In 1994, opinions were nearly the reverse: 63% said immigrants were a burden and 31% said they strengthened the country.

You will note that they views of Republicans and Democrats diverge after 2006.  Millennials are especially favorably inclined.

Last month, De La Rue, the world’s largest currency maker, sent a letter to the central bank complaining that it was owed $71 million and would inform its shareholders if the money were not forthcoming. The letter was leaked to a Venezuelan news website and confirmed by Bloomberg News.

“It’s an unprecedented case in history that a country with such high inflation cannot get new bills,” said Jose Guerra, an opposition law maker and former director of economic research at the central bank. Late last year, the central bank ordered more than 10 billion bank notes, surpassing the 7.6 billion the U.S. Federal Reserve requested this year for an economy many times the size of Venezuela’s.

…While the cash was still arriving — at times, multiple planeloads a day — authorities set their sights on the year ahead. In late 2015, the central bank more than tripled its original order, offering tenders for some 10.2 billion bank notes, according to industry sources.

But currency companies were worried. According to company documents, De La Rue began experiencing delays in payment as early as June. Similarly, the bank was slow to pay Giesecke & Devrient and Oberthur Fiduciaire. So when the tender was offered, the government only received about 3.3 billion in bids, bank documents show.

That is from Andrew Rosati.  Here is a sad and poignant post on the suicide of Venezuela, by Joel D. Hirst.

Since the Greek situation is heating up again, and not in good ways, I thought I would link to a recent interview I did.  Here is one bit:

Asked about what has gone wrong with Greece’s bailouts, Professor Cowen commented that “the bailout programs were never going to work in the first place. The debt is too high and is more of a political weapon than anything which can be paid back. And the Greek economy requires very serious structural reform, more than the Greek people seem to wish to accept. That is two impossibilities in the situation right there, and then on top of that we have a dysfunctional EU, slow global growth across the board, and the refugee crisis. In that setting, can one expect anything other than failure?”
And:

“It’s all a big bargaining game, and at the end of the day pulling the plug will have to be up to the Greeks. Everyone’s expectations are unrealistic, and everyone knows that, including the IMF and EU and many others too. But who will pull the plug? Tsipras almost did, and then backed away. In my view, sooner or later Greece will leave this arrangement because it simply isn’t workable. I don’t look forward to the resulting economic carnage.”

Asked why he thinks Europe has been unwilling to consider a debt-write off for Greece, Cowen said that “because Italy above all would be next in line, but of course Spain too and others as well.”

Here is the conclusion:

Lastly, when I asked Tyler Cowen what policies he would recommend for Greece so the country can re-boost its economy and put people back to work, [he] said this:

“Do you know the old punchline? “Well, I wouldn’t start from here.” Greece has been deindustrializing for a long time, there isn’t enough to take the place of manufacturing, and tourism just isn’t enough. The interest groups seem intractable. I’d like to see Greece have much more of a free market economy, but that’s begging the question, isn’t it? And there is the ongoing distraction and stress of having to renegotiate the agreements every few years. By the way, I can’t bench press 600 pounds.”

What drives you?

by on April 28, 2016 at 2:26 am in Economics, Philosophy | Permalink

In fact, over the years, Mr. Gross has consistently asked one question of prospective employees: What drives you?

The twist is that they must pick one of three answers: money, power or fame.

Strangely to him, no one has ever picked fame.

“It is the one thing I have always wanted,” he said. “When I was starting out at Pimco in 1972, I told my mother and father that I was going to become the most famous bond manager in the world.”

And this:

At night he will wake up as many as three times to check on global markets, he says.

And this:

“My whole evening is dependent on whether I beat them [Pimco, his former employer],” Mr. Gross said. “You see, I have to prove it all over again. Every day.”

The Landon Thomas Jr. NYT Dealbook post is interesting throughout.  And here is a 2008 profile of Gross.

Paul Frijters and Benno Torgler have a new six-page paper (pdf)on that topic, here is the abstract:

The current peer review system suffers from two key problems: promotion of an in-crowd whose methods, opinions and innovations it protects; and failure to represent the opinions and interests of non-peer clients. As a result, whole disciplines orient themselves toward navel-gazing research questions of little import to society or even science as a whole, and new methods and concepts must be unusually persuasive to break through. We thus suggest a more efficient and integrity-preserving system based on an open two-sided market in which buyers and sellers of peer review services would both be subject to a set of recursive quality indicators. We lay out key features we think would be important to reduce the opportunities for gaming and that improve the signals about the societal value of a contribution. Our suggestions include a level of reward offered by the author of a paper to get refereed and a level of desired quality of the referee. They include randomly selecting from a group of referees that express a willingness to accept the offered contract. They include the possibility that papers are put up by non-authors for peer-review for assessment on different criteria, such as societal relevance. And they finally include the possibility that referee reports themselves become refereed by other referees. What we envisage is that such an open market in which all elements are subject to peer review will over time lead to specialized reviewers in different criteria, and more useful signals about the nature and quality of any individual piece of work. Our incentivized market set-up would both professionalize the peer review process and make it completely transparent, an innovation long overdue.

Interesting, but the main problem with the idea is simply that no one cares.

For the pointer I thank Ben Southwood.

The BBC has an interesting report on ambulance services in Beijing.  Up until now, ambulance drivers could decide themselves how much to charge people for their services.  I’m assuming these weren’t listed or known beforehand either.  This seems ripe for abuse given that the patient will be desperately wanting to get to the hospital and in no state for bargaining.  According to the article, most Chinese on social media didn’t even know that ambulances charge at all.  That must come as a big shock then when they get hit up by the driver.

So what did authorities decide to do?  Decree that ambulances “be fitted with taxi-style meters in an effort to allay public concerns about overcharging.”  Hmm, this doesn’t seem to be the most incentive compatible policy either.  As one social media cynic (read: realist) pointed out, “Don’t rule out ambulances taking a detour when using the meter.”  At least when you’re in the backseat of a cab, you can watch where the driver is going.  In the back of an ambulance in an emergency situation, that’s not going to be very feasible!  Don’t get me wrong, I’m in no way advocating free ambulance services, but there has to be a better policy than this.

That is from Cherokee Gothic.
