I might be able to help you. Do you want me to quote it so it makes it a little bit easier? The Department of Finance study said the following:
Corporate income tax measures have a limited impact on aggregate demand over the periods displayed in the table but have among the highest multiplier effects in the long run. This is because they increase the incentive to invest and accumulate capital, which leads to a higher capacity to produce goods and services.
Do you agree with that?
