Micro-level studies provide insightful knowledge on the drivers of the labor income share. This paper introduces a novel firm-level dataset on the labor income share. Using the World Bank Enterprise Survey data, we put together an unbalanced panel comprising 146,666 firms from 139 countries and...

Contradicting the conventional wisdom of constant factor shares, the portion of national income accruing to labor has been trending downward in the last three decades. This decline must have contributed to rising inequality as labor income is more evenly distributed than capital income. This...

The labor income share has been decreasing across countries since the early 1980s, sparking a growing literature about the causes of this trend (Karabarbounis and Neiman, 2014; Piketty and Zucman, 2014; among many others). At the same time, there has been a steady increase in asset prices. We build a...

This paper establishes some stylized facts of the long run relationship between growth and labor shares using historical data for the United States (1898-2010), the United Kingdom (1856-2010), and France (1896-2010). Performing individual country time-frequency analysis, we demonstrate the...

There are two fundamental reasons why factor shares have traditionally been overlooked in the economic literature. First, because of their nature, factor shares are conceptually difficult to define and measure. Second, they have for a long time been perceived as constant across time and space....

Summary statistics on the labor share of income show that between-country variation is much greater than within-country variation: functional income distribution is determined by factors which change substantially across countries but are persistent over time. We attempt to shed some light on...

We present a novel way to model technological shocks, with the feature that it can be biased towards more recently installed production units. We show that at one extreme, the shock is like a neutral technological shock, while at the other end of the spectrum, it resembles investment specific...

The accumulation principle suggests that complementarity between capital and labor forces the labor income share to rise in the presence of capital accumulation. The CES model estimates using data from 20 Japanese industries between 1970 and 2012 explain the same outcome but with substitutable...

The role of capital accumulation as a driver of the labor income share requires capital and labor to be substitutes, which appears paradoxical in a world predominantly characterized by complementarity between capital and labor. This paper argues that the composition of skills in the labor force...

We study the behavior of the US labor share over the past 65 years. We find that intellectual property products (IPP) capital entirely accounts for the observed decline of the US labor share, which otherwise is secularly constant for structures and equipment capital. The decline of the labor...
