Revisiting Capital-Skill Complementarity, Inequality, and Labor Share
This paper revisits capital-skill complementarity and inequality, as in Krusell, Ohanian, Rios-Rull and Violante (KORV, 2000). Using their methodology, we study how well the KORV model accounts for more recent data, including the large changes in the labor's share of income that were not present in KORV. We study both labor share of gross income (as in KORV), and income net of depreciation. We also use nonfarm business sector output as an alternative measure of production to real GDP. We find strong evidence for continued capital-skill complementarity in the most recent data, and we also find ...

Why Is the Labor Share Declining?
The fraction of national income accruing to labor (the labor share) had been roughly constant in developed economies for much of the 20th century but has fallen since the 1980s. We review several of the leading explanations in the literature for the declining labor share. We then point to hitherto unexplored dimensions of the data and provide suggestive evidence for a new explanation. In particular, we show that the labor share began a steeper descent in 2000. This more recent break in the labor-share trend coincides with the rapid rise of software investment, which has left a larger impact ...

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 ...

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 ...

Market Power, Inequality, and Financial Instability
Over the last four decades, the U.S. economy has experienced a few secular trends, each of which may be considered undesirable in some aspects: declining labor share; rising profit share; rising income and wealth inequalities; and rising household sector leverage and associated financial instability. We develop a real business cycle model and show that the rise of market power of the firms in both product and labor markets over the last four decades can generate all of these secular trends. We derive macroprudential policy implications for financial stability.

The Global Rise of Corporate Saving
The sectoral composition of global saving changed dramatically during the last three decades. Whereas in the early 1980s most of global investment was funded by household saving, nowadays nearly two-thirds of global investment is funded by corporate saving. This shift in the sectoral composition of saving was not accompanied by changes in the sectoral composition of investment, implying an improvement in the corporate net lending position. We characterize the behavior of corporate saving using both national income accounts and firm-level data and clarify its relationship with the global ...

Dynamic and Stochastic Search Equilibrium
I study the business cycle properties of wage posting models with random search, for which the distributions of employment and wages play a nontrivial role for the equilibrium path. In fact, the main result of this paper is that the distribution of firms is one of the most important elements to understand business cycle fluctuations in the labor market. The distribution of firms (1) determines which shocks are relevant for the labor market, (2) implies that wage rigidity does not significantly amplify shocks, and (3) puts discipline on the relative value of the flow opportunity cost of ...

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 ...

International Diversification, Reallocation, and the Labor Share
How does growing international financial diversification affect firm-level and aggregate labor shares? We study this question using a novel framework of firm labor choice in the face of aggregate risk. The theory implies a cross-section of labor risk premia and labor shares that appear as markups in firm-level data. International risk sharing leads to a reallocation of labor towards riskier/low labor share firms alongside a rise in within-firm labor shares, matching key micro-level facts. We use cross-country firm-level data to document a number of empirical patterns consistent with the ...

Payments on Digital Platforms: Resiliency, Interoperability and Welfare
Digital platforms, such as Alibaba and Amazon, operate an online marketplace to facilitate transactions. This paper studies a platform’s business model choice between accepting cash and issuing tokens, as well as the implications for welfare, resiliency, and interoperability. A cash platform free rides on the existing payment infrastructure and profits from collecting transaction fees. A token platform earns seigniorage, albeit bearing the costs of setting up the system and holding reserves to mitigate the cyber risk. Tokens earn consumers a return, insulating transactions from the ...
