We analyze the implications of the decline in labor’s share in national income for optimal Ramsey taxation. It is optimal to accompany the decline in labor share by raising capital taxes only if the labor share is falling because of a decline in competition or other mechanisms that raise the...

We study the evolution of labor shares in 1995-2014, while taking into account international trade based on value added concepts. Declines in labor shares accelerate in 2001-2007, concurrently with global value chain (GVC) integration, after which there is no trend for both. We develop a...

To what extent can technological advances in the production of capital account for the recent, worldwide decline in the labor income share? We pose two challenges to the automation narrative: first, estimates of the elasticity of substitution (EOS) between capital and labor tend to fall below or...

This study provides evidence for the US that the secular decline in the labor share is not only explained by technical change or globalization, but also by the dynamics of factor taxation, automation capital (robots), and population growth. First, we empirically find indications of...

Since the beginning of the Industrial Revolution, technological change has led to the automation of existing tasks and the creation of new ones, as well as the reallocation of labor across occupations and industries. These processes have been costly to individual workers, but labor demand has...

The aggregate labor share in U.S. manufacturing declined dramatically over the last three decades: Since the mid-1980's, the compensation for labor declined from 67% to 47% of value added which is unseen in any other sector of the U.S. economy. The labor share of the typical U.S. manufacturing...

We explore the possibility that a global productivity slowdown is responsible for the widespread decline in the labor share of national income. In a neoclassical growth model with endogenous human capital accumulation à la Ben Porath (1967) and capital-skill complementarity à la Grossman et...

This paper examines the implications of Artificial Intelligence (AI) and automation for the taxation of labor and capital in advanced economies. It synthesizes empirical evidence on worker displacement, productivity, and income inequality, as well as theoretical frameworks for optimal taxation....
