On Au

Greg Mankiw has a cool New York Times article and blog post, "On Au" analyzing the case to be made for gold in a portfolio, including a cute problem set. (Picture at left from Greg's website. I need to get Sally painting some gold pictures!)

I think Greg made two basic mistakes in analysis.

From Livestock to the Stock Exchange

Artist's description: This is a brief visual history of trade, reading left to right. The first "money" was cattle, represented by the cheese. Ancient Mesopotamians kept track of their cattle exchanges on cuneiform tablets like receipts (we have some at the Oriental institute of Chicago!). The root of the word "pecuniary" comes from the root "pecu" meaning "cattle." Cowrie shells were another early form of currency for trade, and beaver fur, which was very valuable, was used in barter when Europeans discovered the New World. The coins and stock ticker tape represent the modern end of the history. July 2013. 8"x 16" oil on canvas.

Original here with many other sizes.

Sally says the beaver fur was inspired by a Russ Roberts EconTalk podcast, interviewing Timothy Brook on his book Vermeer's Hat. "Part of the book talked about how valuable beaver fur was for making hats that ended up in the Netherlands during Vermeer's lifetime." I don't know how many other artists listen to EconTalk while painting...

The Value of Public Sector Pensions

The unfunded promises of public sector pensions are in the news, with the Detroit bankruptcy. Josh Rauh at Stanford and Hoover has a nice blog post on the subject titled "Public Sector Pensions are a National Issue''. (Josh and Robert Novy-Marx wrote a very influential paper (ssrn manuscript) alerting us to the size of the state and local pension bomb.)

Josh's baseline number for the value of underfunded pensions: $4 trillion. Why so big, and why is this a surprise? Because many governments calculate their funding by assuming they will earn 8% per year. Discounting a riskless liability (pensions) at a risky rate is a basic error in finance. It's made all the time. University presidents are notorious for demanding their endowments "reach for yield" in order to "make our rate of return targets."

Reading this piece sparks a few thoughts about the risks posed by pensions and other unfunded liabilities.

Are we prepared for the next financial crisis?

Health Insurance and Labor Supply

I just ran across an interesting paper, "Public Health Insurance, Labor Supply, and Employment Lock" by  Craig Garthwaite,  Tal Gross and my Booth colleague Matthew Notowidigdo.

They study an interesting event

... In 2005, Tennessee discontinued its expansion of TennCare, the state’s Medicaid system. ... Approximately 170,000 adults (roughly 4 percent of the state’s non-elderly, adult population) abruptly lost public health insurance coverage over a three-month period.

The result was

a large and immediate labor supply increase....we find an immediate increase in job search behavior and a steady rise in both employment and health insurance coverage. 

A Ray of Hope? Hospitals Post Prices

I was intrigued by news stories of an Oklahoma hospital posting prices for surgery -- prices far below those offered by its competitors. Here is the article and the surprisingly low price list.  Several competitors felt the pressure to slash and post prices.
