The Invisible Run-Off
Today, the Alphaville section of the Financial Times published The invisible run-off, in which I discuss a new source of “quantitative tightening” that almost no one seems to have noticed. I estimate that $350 billion of private funds will be absorbed when the U.S. Treasury refinances its securities that are now in special accounts for state and local government bonds. The Treasuries are…

My Letter to the Wall Street Journal
My Letter to the Wall Street Journal
The Wall Street Journal just published a letter of mine, Debt Bomb has Shorter Fuse Than Many Citizens Think (credit to them for the snappy title, and to my wife Corrina for invaluable editing). I respond to the Journal’s recent editorial Obama’s Debt Interest Bomb.
The editorial warned of a growing burden of interest payments on the national debt, due to rising interest rates and the…

Quarter the Cross: An Elegant Construction
Quarter the Cross: An Elegant Construction
Last month, I presented an infinite pattern of nested crosses as a response to the #QuarterTheCross challenge on Twitter. The idea is to find interesting ways to shade one-quarter of the area of the cross built from five squares.
Now David Butler, a math lecturer at the University of Adelaide, has found an elegant way to construct this pattern with the classic tools of compass and straightedge(I…

Quarter the Cross
Yesterday, I noticed that some of the math teachers I follow on Twitter were challenging their students, and themselves, with the #quarterthecross problem. The problem is simply to find interesting regions of a five-square cross that take up exactly one-quarter of its area. This looks like a great way to get kids to explore fractions and geometry.
A solution that occurred to me would be to use…

My FT Alphaville Commentary on Managing U.S. Treasury Debt
My FT Alphaville Commentary on Managing U.S. Treasury Debt
My commentary Go Long, Mr Mnuchin has just been posted at FT Alphaville of the Financial Times. I address the questions of whether the U.S. Treasury debt should be lengthened and whether it should use 50-year or 100-year bonds to do so. These are hot topics that the likely next Secretary of the Treasury raised after he was nominated last fall. I think that “ultra-long” bonds are good idea but…

NAMA in NOLA
I am excited to go to New Orleans this week to speak at the annual conference of the National Association of Municipal Advisors (NAMA). I will be on a panel about bond structuring with Lori Raineri of Governmental Financial Strategies Inc., Dave Abel of William Blair, and Shelley Aronson of First River Advisory. We will discuss some of the important structuring questions that face municipal…

Taming Premium Bonds The Bond Buyer published my commentary Taming Premium Bonds earlier today. Although callable premium bonds are very popular in the municipal market, I argue that they hurt issuers and the market.

Spoiler Alert: Stop here if you want to solve the puzzle yourself! Answers (some correct and some not) will be given below.
This innocent-seeming puzzle stirred several math teachers to exchange ideas, diagrams and animations. Some of them changed their minds about it…

A Mathematician’s New Year’s Resolutions Speaking of the new year, here are some funny resolutions from the "Math with Bad Drawings" blog. I like the one about completing chores in finite time. I bet Zeno never finished cleaning his room!
Happy 5 2 01!
Happy 5 2 01!
Last year, in Happy 0 0 1 0 0 1 0 0 0 0 1!, I discussed an interesting way to represent numbers based on their prime factorization. For example, 63 is represented by 0 2 0 1 because 63 = 20 x 32 x 50 x 71.
In the prime power representation, 2015 was 0 0 1 0 0 1 0 0 0 0 1. However, with 2016 = 25 x 32 x 50 x 71, this year can be represented by the more concise 5 2 0 1.
I doubt you can express…
