Summary and Keywords
All governments require revenue, and domestic taxes are the primary means for generating it. Yet both the size and shape of taxation vary significantly across countries and have been transformed over time. What explains variation in domestic taxation? To answer this question, recent scholarship on taxation has focused on the politics of taxation as a tool for redistribution. This has led to a wide body of research on the fiscal impact of taxation and on the introduction, evolution, and variation in direct and progressive tax regimes, particularly the income tax. Yet the focus on taxation as a redistributive tool yields a puzzle, as more progressive tax systems tend to be found where redistribution is in fact the lowest. Explanations of this paradox often center on the impossibility of high and progressive taxes on capital in the context of international economic integration. Not as well studied are taxes other than the taxation of income, and the deliberate politics of nonfiscal, regulatory, and incentive effects of different tax choices. Methodologically, problems of endogeneity are ubiquitous in the study of tax policy choices, but more sophisticated experimental work is well underway in research on individual preferences for taxation.
