Typically speaking, when we analyze a proposal—for example, a rate reduction—we look at several things, based on certain principles. We look at the potential effectiveness. We look at the efficiency of a proposal. We look at the equity implications of that. We look at which groups of people, by income, age and gender, will be affected and how. We look at whether or not a potential proposal would have implications in terms of the simplicity versus complexity on the tax system. We try also to consider any implications for administering a potential change.
