forecast

Alright, we got the update from the city and it was not pleasant. Year-to-date collections are down more than 10%, and cities preferred measure (though we do not know why it is preferred) is down 6.87%. The forecast was for $1.35 million in collections and it came in at $1.02 million. So my pessimistic forecast was still too rosy. Based on this the updated forecast for May is revised down to $1.3 million.

Over the past few weeks the conversation about sales tax has been pretty consistent and fairly intense. That is probably as it should be given the overall importance of revenue generation across the state right now. What have I done so far?

Eleven of twelve months in the series are the same from one month to the next so of course the series is stable. The flaws of this approach can be seen when you look at the recent decline. A good month is totally outweighed by the totality of the previous eleven. It also begs a statistical question: should all these months be given equal weight while in the series and then just disappear? That seems highly suspect.

The latest numbers from the state OMB showed some interesting information regarding taxes, again. Rather than focus on sales tax this time I thought we could branch out into income taxes. Why? Sales tax revenues get the bulk of attention in the media and from me generally and I think branching out is important. Another reason is as the impacts and effects of the oil decline transmit into other sectors more fully, and the state budget cutting starts to fully take effect, we will see other revenues exhibit declines. My interest in the overall forecasting process, if we can call it that, also means we need to branch out into other revenue areas to understand the complete picture of the revenue process. The individual income tax revenue was also almost $20 million short of the forecast in May. With that in mind here is the picture for actual versus forecast individual income tax revenues in North Dakota:

The state released an updated forecast from Moody’s today along with some slides that make little sense (found here). I would go into the details of the forecast but why bother? We have absolutely no insight into the forecast process followed, the assumptions underlying any model relationships, or even a list of variables employed and the time period considered. Seriously, if this were my forecasting class, they would fail.
