A Wisconsin Fixed Effect

Wisconsin’s unemployment rate has dropped to 2.8 percentage points in April. The national rate is 3.9 percentage points. Proof of Walkernomics success? Well, since on average Wisconsin’s unemployment rate is typically 0.9 percentage points below, the answer is “no”. Consider the Wisconsin and US unemployment rates.

How Many Times Have the 10y2y and 10y3m Spreads Concurrently Broken the 1% and 0.5% Thresholds w/o Subsequent Recession?

If one uses a three year window, it’s three times: February, 1986, May 1995, September 1997. Three other times, a recession follows.

The last time around — when people were saying “this time is different” — was May 2005. Inversion occurred in February 2006 (and in November 2006, skepticism of impending recession). The recession is dated by NBER as starting in December 2007.

For additional discussion of the implications of a flattening yield curve, see Michael Klein’s EconoFact article, and (for cross country empirics) Chinn and Kucko (2015).

The US Petroleum Trade Balance

As oil prices start heading up, the usual questions arise regarding the macro implications. One view is that with the revolution in tight oil production, the US will experience less of a negative impact than before. This conclusion relies on a set of assumptions, possibly including the US being substantially less dependent on oil imports. Is this true?

Guest Contribution: “The ECB’s Strong Euro Problem”

Today, we are fortunate to present a guest contribution written by Ashoka Mody, Charles and Marie Visiting Professor in International Economic Policy, Woodrow Wilson School, Princeton University. Previously, he was Deputy Director in the International Monetary Fund’s Research and European Departments.


The euro has appreciated 10 percent against the Swiss franc (CHF) over the past year. The U.S. dollar and the Japanese yen have not made similar gains vis-à-vis the franc. Tracking the franc’s movements relative to the major currencies gives an unusual window onto the deflation-fighting credentials of the world’s major central banks. It illustrates, in particular, the European Central Bank’s half-hearted efforts to fight the risk of price deflation. Financial markets have come to believe that the ECB will prematurely tighten monetary policy: hence, despite brief episodes of depreciation, the euro will tend to stay strong, hurting economic prospects in several eurozone member countries.

The Reagan Tax Cuts and Defense Buildup: Supply-Side Miracle or Keynesian Stimulus?

I keep on hearing about the supply-side miracle associated with the the Reagan era tax cuts. What do changes in estimated potential versus actual output suggest?
