This series of working papers explores a theme enjoying a tremendous resurgence: the functional distribution of income - the division of aggregate income by factor share. This first installment surveys some landmark theories of income distribution. Some provide a technology-based account of the...

Existing studies on the downward trend in the labor share of income mostly focus on changeswithin individual countries. I document, however, that half of the global decline in the laborshare of income can be traced to the relocation of activities between countries. I develop atwo-country model...

This paper provides evidence that shifts in the occupational composition of the U.S. workforce are the most important factor explaining the trend decline in the labor share over the past four decades. Estimates suggest that while there is unitary elasticity between equipment capital and...

As the pace of digitalization and automation accelerates globally, and more disruptive innovations in machine learning, artificial intelligence and robotics are expected, new data sources and measurement tools are needed to complement existing valuable statistics and administrative data. This is...

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...

Technological progress may be less beneficial for older workers than younger workers. In this paper, we empirically examine the impact of technological change on the wage share of older workers. More specifically, we look at five different types of technological advancement using data from 30...

The non-constancy of factor shares is drawing the attention of many researchers. We document an average drop of the labour share of 8 percentage points for eight European countries and the US between 1980 and 2007. We investigate theoretically and empirically two mechanisms: the substitution...

Over the past two decades, real median wage growth in many OECD countries has decoupled from labour productivity growth, partly reflecting declines in labour income shares. This paper analyses the drivers of labour share developments using a combination of industry- and firm-level data....

As shown in the 1930s by Hicks and Robinson, the elasticity of substitution (σ) is a key parameter that captures whether capital and labor are gross complements or substitutes. Establishing the magnitude of σ is vital, not only for explaining changes in the distribution of income between...

This paper provides novel insights on the changing functional distribution of income in the post-war US economy. We present a Divisia index decomposition of the US labor share (1948–2017) by fourteen sectors. The decomposition method furnishes exact contributions from four components towards...
