I just heard a very interesting proposal from Lawrence Lindsey (as a guest on the Daily Show) regarding economic stimulus strategy. He proposed that rather than spending $B top-down – instead reduce personal and business taxes by an equivalent amount of $B of investment. He noted the potential benefits of quickly putting money into the pockets of individual workers which can be put into the economy, and reducing business operations costs – providing incentive to create jobs/maintain jobs. An interesting idea.
For those with $5,000 laying around and some time on your hands – you could do some simulation on various tax policies using this Stats Canada simulation software and data.
