(St. Paul, MN)  --  Minnesota state tax collections in February and March were 41-million-dollars less than predicted, but officials say it appears to be from differences in timing of tax receipts and refunds -- and does not indicate an economy that's weaker than projected. The state's economic experts say it appears real Gross Domestic Product has grown for three consecutive quarters and, barring any unforeseen financial shock, the threat of a "double-dip" recession has passed.  They credit the federal government's actions with averting a much longer and deeper recession.  But experts say consumer attitudes have yet to reflect the improved outlook and add that lingering employment concerns, slow wage growth and tight credit will likely inhibit household spending until 2011. Forecasters say they don't expect consumer spending to drop, but there's also no sign that it will surge, as historically occurs after deep recessions.
