The results of this research, which show the varying levels of responsiveness to the same change in tax credit, would suggest that there could potentially be different tax credits for different sectors. Now, on the government level, it's getting kind of messy, but potentially there could be a specific tax credit for social services and health centres and a different tax credit for a religious sector. Of course, it brings to light all kinds of normative discussions about which sectors are more important than others, so it gets politically messy, but that's what the research implies—that sectors do respond differently to the tax credits, and that potentially that would be the way to go forward.
