This paper argues that tax avoidance by large corporations has contributed to the 25% increase in concentration among U.S. firms since the mid-1990s. Corporate tax avoidance gives large firms a competitive edge, which translates into larger market shares and an increase in the granularity of the...

This paper argues that tax avoidance by large corporations has contributed to the 25% increase in concentration among U.S. firms since the mid-1990s. Corporate tax avoidance gives large firms a competitive edge, which translates into larger market shares and an increase in the granularity of the...

Large and sustained differences in marginal products of capital (MPKs) across countries are sharply at odds with the core implications of the neoclassical framework. Lucas (1990) and many subsequent studies have examined reasons for this MPK differential. In a recent contribution, Caselli and...

Immigration may impact income distribution both by affecting the skill composition of a country's residents, and, by changing relative factor supplies, its relative factor prices. We provide some background evidence on compositional factors but focus primarily on factor prices. We first consider...

Wages grow but also become more unequal as workers age. Using German administrative data, we largely attribute both life-cycle facts to one driving force: some workers progress in hierarchy to jobs with more responsibility, complexity, and independence. In short, they climb the career ladder....

I study the optimal taxation of robots and labor income. In the model, robots substitute for routine labor and complement non-routine labor. I show that while it is optimal to distort robot adoption, robots may be either taxed or subsidized. The robot tax exploits general-equilibrium effects to...

Nearly 75 years ago, John Hicks introduced and formalized the concept of the elasticity of substitution between capital and labour and its relation to derived demand. The resulting formula has proven very useful in understanding the derived demand for productive factors, the distribution of...

In the middle of the nineties, the sharp increase in globalisation and the last privatization wave have promoted the shaping of a market for executives in France. Characteristics of this market are estimated for France and a competitive model is simulated in order to assess to what extend such a...

We examine the determinants of differences across countries and over time in the distribution of personal incomes in the OECD. The Gini coefficient of personal incomes can be expressed as a function of the wage differential, the labour share, and the unemployment rate, hence labour market...

This paper develops a tractable, heterogeneous agents general equilibrium model where individuals have different endowments of the factors that complement the schooling process. The paper explores the relationship between inequality of opportunities, inequality of outcomes, and efficiency in...
