Tax policy and tax administration can have a big impact on who does or does not pay their fair share, on economic incentives, and thus on levels of poverty and the distribution of income and welfare. Research under this theme focuses on developing a better understanding, in specific contexts, of the complex economic and political linkages between how governments tax, how their national economies perform, and how well their citizens live. Some of our specific concerns are: the taxation of high net worth individuals; efficient business taxation; and the taxation of socially-harmful activities like smoking tobacco.
