The Department of Revenue’s Wisconsin Economic Outlook, released last week, details a noticeable deterioration in forecast performance, in just the eight months.

2014Q1 personal income was 1% less (in log terms) than the March 2014 forecast. The forecast for 2014Q2 was revised downward by 1.1%.

The mark down in prospects makes sense once one sees the trajectory of Wisconsin economic activity, as measured by the Philadelphia Fed’s coincident indices (October figures released today):

According to this measure, the cumulative growth gap between Wisconsin and the US (and Minnesota) is again widening.

The ramifications of the downgrade in economic outlook are clear. From Wisconsin Budget Blog:
