This essay discusses the reasons for and implications of the decline in real interest rates around the world over the past several decades. It suggests that the decline in interest rates is largely explicable from trends in saving, growth, and markups. In this environment, greater government...

This paper describes the response of the economy to large shocks in a nonlinear production network. While arbitrary combinations of shocks can be studied, it focuses on a sector's tail centrality, which quantifies the effect of a large negative shock to the sector - a measure of the systemic...

This paper considers the consequences of a two-sector vertically-integrated model of firms producing output using firm-specific capital with a second sector producing firm-specific capital by adapting raw capital purchased in the market. Analysts rarely observe each sector separately....

This paper studies the evolution of China's production and trade patterns during its integration into the global economy. We document and explain new facts concerning changes in production and exports at the industry and firm levels using microdata and a quantitative Ricardian and...

When is a wealth tax preferable to a capital income tax? When is the opposite true? More generally, can capital taxation be structured to improve productivity, incentivize innovation, and ultimately increase welfare? We study these questions theoretically in an infinite-horizon model with...

When explaining the declining labor income share in advanced economies, the macro literature finds that the elasticity of substitution between capital and labor is greater than one. However, the vast majority of micro-level estimates shows that capital and labor are complements (elasticity less...

The recent shift to remote work raised the amenity value of employment. As compensation adjusts to share the amenity-value gains with employers, wage-growth pressures moderate. We find empirical support for this mechanism in the wage-setting behavior of U.S. employers, and we develop novel...

We study the importance of firm sorting for spatial inequality. If productive locations are able to attract the most productive firms, then firm sorting acts as an amplifier of spatial inequality. We develop a novel model of spatial firm sorting, in which heterogeneous firms first choose a...

This paper constructs time series of global profit shifting covering the 2015-19 period, during which major international efforts were implemented to curb profit shifting. We find that (i) multinational profits grew faster than global profits, (ii) the share of multinational profits booked in...

We examine whether corporate money in politics benefits or hurts labor using the 2010 Supreme Court ruling Citizens United, which rendered bans on political election spending unconstitutional. In difference-in-difference analyses, affected states experience increases in both capital and labor...
