This Handbook entry presents a conceptual, normative overview of the subject of taxation. It emphasizes the relationships among the main functions of taxation—notably, raising revenue, redistributing income, and correcting externalities—and the mapping between these functions and various...

We set up an OLG-model, where households both choose human capital investment and decide on investing their endogenous savings in a portfolio of riskless and risky assets, exposing them to (aggregate) wage and capital risks due to technological shocks. We derive the optimal public policy mix of...

This chapter provides a review of some implications of demographic shift arising from population aging for fiscal policy, taxation policy, and social security settings. The key implications of population aging that have been forthcoming from the many national and international macroeconomic...

We study Pareto optimal tax and education policies when human capital upon labor market entry is endogenous and individuals face wage uncertainty. Though optimal labor distortions are history-dependent, i.e. depend on income and education, simple policy instruments can yield the desired...

Relative consumption effects or status concerns that feature jealousy (in the sense of Dupor and Liu, 2003) boost consumption expenditure. If consumption is financed by labour income, such status considerations increase labour supply and, hence, the tax base. A higher taxable income, in turn,...

This article explores subjects in optimal income taxation characterized by recent research interest, practical importance in light of concerns about inequality, potential for misunderstanding, and prospects for advancement. Throughout, the analysis highlights paths for further investigation....

Products with negative externalities are often subject to regulations that limit competition. The single-product case may suggest that it is irrelevant for aggregate welfare whether output is restricted via corrective taxes or limiting competition. However, when products are differentiated...

This paper studies the role of family size in the design of optimal income taxation. We consider a second best setting where the government observes the number of children and the income of the parents but not their productivity. With a linear tax schedule the marginal tax rate is shown to...

This paper deals with optimal income and commodity taxation in an economy, where alcohol is an externality-generating consumption good. In our model, alcohol can be bought domestically, imported, or produced illegally. Border trade alone implies an incentive to set the domestic alcohol tax below...

This paper extends the previous literature on optimal redistributive taxation in the presence of externalities to a multiexternality setting. While taxes on income and on 'clean' commodities are still unaffected by the externalities, which confirms previous results, I find that the existence of...
