This paper analyses optimal income taxes over the business cycle under a balanced-budget restriction, for low, middle and high income agents. A model incorporating capital-skill complementarity in pro- duction and differential access to capital and labour markets is de- veloped to capture the...

This paper undertakes a normative investigation of the quantita- tive properties of optimal tax smoothing in a business cycle model with state contingent debt, capital-skill complementarity, endogenous skill formation and stochastic shocks to public consumption as well as total factor and...

This paper considers the role of human capital accumulation of agents differentiated by skill type in the joint determination of social mobility and the skill premium. Our approach allows us to evaluate the dynamic e¤ects of tax reforms and education spending policies on economic e¢ ciency as...

The stylized facts suggest a negative relationship between tax progres- sivity and the skill premium from the early 1960s until the early 1990s, and a positive one thereafter. They also generally imply rising tax progressivity, except for the 1980s. In this paper, we ask whether optimal tax...

This paper examines whether efficiency considerations require that optimal labour income taxation is progressive or regressive in a model with skill heterogeneity, endogenous skill acquisition and a production sector with capital-skill complementarity. We find that wage inequality driven by the...
