Does Redistribution Increase Output? The Centrality of Labor Supply
The aftermath of the recent recession has seen numerous calls to use transfers to poorer households as a means to enhance aggregate activity. We show that the key to understanding the direction and size of such interventions lies in labor supply decisions. We study the aggregate impact of short-term redistributive economic policy in a standard incomplete-markets model. We characterize analytically conditions under which redistribution leads to an increase or decrease in effective hours worked, and hence, output. We then show that under the parameterization that matches the wealth distribution ...

Top Income Inequality in the 21st Century: Some Cautionary Notes
We revisit recent empirical evidence about the rise in top income inequality in the United States, drawing attention to key issues that we believe are critical for an informed discussion about changing inequality since 1980: the definition of income (labor versus total), the unit of analysis (individual versus tax unit), the importance of partnership and S-corporation income, income shifting between the corporate and personal sectors in response to tax incentives, the definition of the top of the distribution, and trends in the middle and bottom of the distribution. Our goal is to inform ...

Corporate Tax Cuts and the Decline of the Manufacturing Labor Share
We document a strong empirical connection between corporate taxation and the manufacturing labor share, both in the US and across OECD countries. Our estimates associate 30 percent to 60 percent of the observed decline in labor shares with the fall in corporate taxation. Using an equilibrium model of an industry where firms differ in their capital intensities, we show that lower corporate tax rates reduce the labor share by raising the market share of capital-intensive firms. The tax elasticity of the labor share depends on the joint distribution of labor intensities and value added at the ...

Capital-Task Complementarity and the Decline of the U.S. Labor Share of Income
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 non-routine tasks, equipment capital and routine tasks are highly substitutable. Through the lenses of a general equilibrium model with occupational choice and the estimated production technology, I document that the fall in relative price of equipment capital alone can explain 72 percent of the observed ...

The Future of Labor: Automation and the Labor Share in the Second Machine Age
We study the effect of modern automation on firm-level labor shares using a 2018 survey of 1,618 manufacturing firms in China. We exploit geographic and industry variation built into the design of subsidies for automation paid under a vast government industrialization program, “Made In China 2025,” to construct an instrument for automation investment. We use a canonical CES framework of automation and develop a novel methodology to structurally estimate the elasticity of substitution between labor and automation capital among automating firms, which for our preferred specification is 3.8. ...

Endogenous Bargaining Power and Declining Labor Compensation Share
Workhorse search and matching models assume constant bargaining weights, while recent evidence indicates that weights vary across time and in cross section. We endogenize bargaining weights in a life-cycle search and matching model by replacing a standard Cobb-Douglas (CD) matching function with a general constant elasticity of substitution (CES) matching function and study the implications for the long-term labor share and bargaining power in the U.S. The CES model explains 64 percent of the reported decline in the labor share since 1980, while the CD model explains only 28 percent of the ...

Have US Households Depleted All the Excess Savings They Accumulated during the Pandemic?
During the COVID-19 pandemic, US households accumulated a historically high volume of personal savings. As the crisis waned, personal savings started to decline. Economists disagree on whether households have drained their excess savings, and they disagree on which income group is more likely to have done so. The lack of consensus stems from different assumptions about today’s long-term saving rate, which is used as a benchmark to define excess savings. If households need to set aside a higher share of their income now relative to before the pandemic, then pandemic-era excess savings have ...

Consumption, Wealth, and Income Inequality: A Tale of Tails
We provide evidence that the distributions of consumption, labor income, wealth, and capital income exhibit asymptotic power-law behavior with a strict ranking of upper tail inequality, in that order, from the least to the most unequal. We show analytically and quantitatively that the canonical heterogeneous-agent model cannot replicate the proper ranking and magnitudes of these four tails simultaneously. Mechanisms addressing the wealth concentration puzzle in these models through return heterogeneity lead to a mirror consumption concentration puzzle. We match the cross-sectional data on ...

Credit and the Labor Share: Evidence from U.S. States
We analyze the role of credit markets in explaining the changes in the U.S. labor share by evaluating the effects of state-level banking deregulation, which resulted in improved access to cheaper credit. Utilizing a difference-in-differences strategy, we provide causal evidence showing labor share declined following the interstate banking deregulation. We show that the lower cost of credit, increase in the availability of credit, and greater bank competition in each state are mechanisms that led to the decline in the labor share. We use this evidence to obtain the elasticity of labor share ...
