Just a few further thoughts, as yet completely unrefined, about the radio program today. The major discussion on the radio today was taxes. This is always an interesting topic because callers often provide multiple, and often contradictory, views of taxation. It is good that radio is not a visual medium (for many, many reasons) but the confused look on my face when listening to some of the callers would not be taken well I am sure.
Yesterday’s post (found here) mentioned Grand Forks retail and the fact that sales were behind last year’s level. As a recap, the accumulated total of monthly collections in 2016, when compared to the same month in 2015, were all lower, and in some cases by significant amounts. Collections from a few specific months were ahead of the same month the year before, but the accumulated total never got higher than 2015.
Location matters. A lot. The more I read and study about the North Dakota economy the clearer that becomes. As I go through this I am looking more and more at the various locations for economic activity in the state, as the following map demonstrates.
I did some looking at sales tax revenues. I went back to July of 2009 and stopped the graph at December 2015. I will have a separate post looking at the circumstances after that date with the revision of the forecast and what happened then. These data come from the state OMB Rev-E-News publication released monthly.
This is going to get a bit more technical than many of my other posts. However, I am a big believer that there is no reason to shy away from complexity, particularly when avoiding it sacrifices accuracy. So we are going to discuss forecast performance for sales tax in North Dakota. There are many different ways to evaluate forecasts and the one I will use here is called a tracking signal.
