Typical. The government is doing the exact opposite of what they should do. Remember the Great Depression? Similar mistakes were made. Gas tax is there because they are trying to cure an externality of gas which is pollution. Raise the tax decrease the pollution to acceptable levels as people buy less gas. When gas prises are rising as they have been you do not increase taxes further. This will create a deadweight loss on the economy and you will see the price of all goods that use gas as an input rise. Since just about everything is moved by truck this means everything will go up in price. The economy will slow, GDP will be down. Dumb! Lowering the tax to stimulate the economy in the face of rising gas prices would be a better solution.
in theory you are partiallly correct and only in the short run and as it applies only to the state of CO,
the US' GDP output will not be drastically affected by the "slowing economy" of a single states do to a slight increase in a locality/municipality tax, decreasing/increasing a minor tax like a gas tax/sales tax doesn't have as big of an impact on the national economy as per say income taxes.
either way i'm not a fond proponent of sole-fiscal policy usage for economic stimulation, IMHO and my my interpritation
s of macroeconomic theory monetary policy seams to have a better effect on the national level. i hope it doesn't make it to the public.
