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...

Are there still opportunities for welfare-improving reforms in unfunded pension systems? To answer this question, we analyze the intertemporal structure of implicit taxes in pay-as-you-go pension schemes. We demonstrate that these tax rates are declining over the life cycle. This timing is...

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....

In many countries elderly workers are subject to a double distortion when they consider prolonging their activity: the payroll tax and a reduction in their pension rights. It is often argued that such a double burden would not be socially desirable. We consider a setting where it would be...

A model is presented for simulating the level of taxes imposed on highly skilled labor. The effective average tax rate, defined as the relative wedge between employment costs and disposable income, is computed. Income and payroll taxes and social security contributions not yielding an equivalent...

In OLG economies with life-cycle saving and exogenous growth, competitive equilibria in general fail to achieve optimality because individuals accumulate amounts of physical capital that differ from the one that maximizes welfare along a balanced growth path (the Golden Rule). With human...

Spain’s government has introduced ambitious consolidation measures, which should yield a sizeable improvement in discretionary fiscal efforts. Should budgetary outcomes fall short of targets, the government should stand ready to introduce further measures, as announced. Such measures could...

The distributional effects of the minimum wage are analyzed in a model where skilled and unskilled labor are inputs into the production function. It is argued that distributional goals are best achieved by letting the labor market clear itself and achieving redistribution through taxes and...

France has a track record of persistent general government deficits, partly reflecting pro-cyclical fiscal policies in upswings. This has resulted in a quadrupling of its public debt-to-GDP ratio since the 1970s to above 80% of GDP. Reducing public debt is crucial because a high level of public...

This paper analyzes the dynamic politico-economic equilibrium of a model where repeated voting on social security and the evolution of household characteristics in general equilibrium are mutually affected over time. In particular, we incorporate within-cohort heterogeneity in a two-period...
