Yesterday I learned that the person who first used the term "duality" in connection with linear programming, indeed with anything in economics, was John von Neumann in a private conversation with George Dantzig in 1947, the "father of linear programming."  That was the year Dantzig published his paper showing the simplex method for solving linear programming problems, bot their primals and their  duals.  Von Neumann wrote a paper on it the same year but did not publish it, with it only...

Yeah, I know, the Iran situation is more in the headlines, but nobody knows anything and everybody is shooting off their mouths.  I shall comment on that one when things settle down a bit.Instead I shall provide info less widely reported coming out of nkecon on the still-unreported-in-MSM story about the increasingly bad food situation in North Korea (DPRK). There are multiple reports.  Drought has hit the principal rice growing area in DPRK.  Also, there is now a serious situation regarding...

I want to follow Dean Baker in dumping on the Robert J. Samuelson Monday, 9/11/19 WaPo column on "The Democrats' fairy-tale campaigns."  He may be right that lots of proposals have been put forward with no clear accounting of how much all of them will cost, but RJS also fails to recognize some might save money, such as a properly structured universal health care program that might move us more towards the costs we see in other nations.  Of course, RJS regularly uses this column to call for...

Yes, I am watching "The Longest Day" on TMC.  Have not seen it for decades, but this 75th anniversary of D-Day seems to be the time to do it.  This will be a rambling post all over the place.  I note that according to the film, it was German Field Marshall Rommel who is depicted calling it "the longest day," the day before it happened, seeing it coming.I have been there several times, first in Fall 1953 when I was young and it was cold and rainy.  Three times in1994, 1997, and 2002 I and my...

Thanks to Greg Mankiw, I’ve seen a preview of the piece by Sam Bowles and Wendy Carlin that will be published in a forthcoming Journal of Economic Literature.  It’s apparently part of a roundtable on the teaching of introductory economics, and not surprisingly Bowles and Carlin focus on the freely downloadable CORE text produced with support from the Institute for New Economic Thinking.  The starting point of their article is the revolution in economic textbooks inaugurated by Paul Samuelson...

President Trump's threat to impose tariffs on Mexico over immigration has pushed Federal Reserve Chair Jay Powell to say that if the tariffs lead to economic growth slowing, the Fed will cut interest rates.  While the bump may be about to end, this announcement was followed by a  solid global surge of stock markets on June 4 followed by smaller increases the next day.  This sets up a moral hazard situation for Trump where if he behaves irresponsibly on trade policy (with even GOP senators...

What follows is some unsolicited advice for the Sanders campaign.Politico has an important piece on the downside of the extraordinary age bias in Sanders’ support.  Like a teeter totter, the large advantage Sanders enjoys among younger voters is counterbalanced by his dismal showing among the older crowd.  The article reviews voting breakdowns from the 2016 campaign and current poll results, and it shows that Sanders is not just behind among seniors, but way, way behind.  His political...

Menzie Chinn has been reading the latest Economic Report of the President and finds a very erroneous and misleading chart, which is figure 1-6 from this this document (see page 45), which states: Equipment investment, in particular, exhibited a pronounced spike in the fourth quarter of 2017, as both the House and Senate versions of the TCJA bill, which were respectively introduced on November 2 and November 9, stipulated that full expensing for new equipment investment would be retroactive...

Douglas Irwin is a very good economist. Let’s highlight his Historical Perspectives on U.S. Trade Policy: The Civil War marked the beginning of a long period of high U.S. tariffs. These tariffs served the dual purpose of raising revenue for the federal government and keeping out foreign goods, ostensibly for the protection of U.S. labor and business. After the war, tariffs (which generated roughly half of government revenue) remained high to service the enormous debt burden that resulted...

Can The Hill be more wrong? President Trump will award the Presidential Medal of Freedom, the nation's highest civilian honor, to economist Arthur Laffer, the White House announced Friday. The president will honor Laffer on June 19 for his contributions to economic policy. The White House described Laffer as "one of the most influential economists in American history" in announcing the award. OK the Idiot-in-Chief did say that but repeat after me – Art Laffer is not an economist. Why did...
