We examine the concerns that new technologies will render labor redundant in a framework in which tasks previously performed by labor can be automated and new versions of existing tasks, in which labor has a comparative advantage, can be created. In a static version where capital is fixed and...

We construct new technology indicators using textual analysis of patent documents and occupation task descriptions that span almost two centuries (1850-2010). At the industry level, improvements in technology are associated with higher labor productivity but a decline in the labor share....

Data on consumption inequality are too fragile to reach firm conclusions. We introduce two new issues, disparities in the growth of price indexes and also of life expectancy between the rich and the poor. We conclude with a perspective on international differences that blends institutional and...

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 a la Ben Porath (1967) and capital-skill complementarity a la Grossman et al....

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

Thomas Piketty's (2014) book, Capital in the 21st Century, follows in the tradition of the great classical economists, like Marx and Ricardo, in formulating general laws of capitalism to diagnose and predict the dynamics of inequality. We argue that general economic laws are unhelpful as a guide...

This paper uses millions of records from a cross-country and time series database of both publicly listed and private companies to disentangle the role of technological change, market power, and globalization in driving a fall in the labor share. Labor shares are measured at the enterprise level...

We provide an argument for long-term automation and decline in the labor income share, driven by capital accumulation rather than technical progress or rising markups. We emphasize a fundamental asymmetry across physical and human capital. An individual can indefinitely replicate her claims on...

The fall of labor's share of GDP in the United States and many other countries in recent decades is well documented but its causes remain uncertain. Existing empirical assessments of trends in labor's share typically have relied on industry or macro data, obscuring heterogeneity among firms. In...

The recent fall of labor's share of GDP in numerous countries is well-documented, but its causes are poorly understood. We sketch a "superstar firm" model where industries are increasingly characterized by "winner take most" competition, leading a small number of highly profitable (and low labor...
