We assess the concentration and duration of zero tax liabilities and of transfer receipts, using data for households with ten to forty years of observations from the Panel Survey of Income Dynamics. We find that neither is strongly concentrated. Nearly 68% owe no federal tax in at least one...

We examine immigrant entrepreneurship and the survival and growth of immigrant-founded businesses over time relative to native-founded companies. Our work quantifies immigrant contributions to new firm creation in a wide variety of fields and using multiple definitions. While significant...

We study immigrant entrepreneurship and firm ownership in 2007 and 2012 using the Survey of Business Owners (SBO). The survival and growth of immigrant-owned businesses over time relative to native-founded companies is evaluated by linking the 2007 SBO to the Longitudinal Business Database...

The economics of climate change involves a vast array of uncertainties, complicating both the analysis and development of climate policy. This study presents the results of the first comprehensive study of uncertainty in climate change using multiple integrated assessment models. The study looks...

We study how inequality, skills, and economic activity adjust over time to technological innovations. We develop a theory of technological transitions where economies adjust through two margins: (i) within-generation reallocation of workers with heterogeneous skills, and (ii) cross-generation...

We leverage a large-scale incentivized survey eliciting behaviors from (almost) an entire university student population, a representative sample of the U.S. population, and Amazon Mechanical Turk (MTurk) to address concerns about the external validity of experiments with student participants....

We design and conduct large-scale surveys and experiments in six countries to investigate how natives perceive immigrants and how these perceptions influence their preferences for redistribution. We find strikingly large misperceptions about the number and characteristics of immigrants: in all...

Populism may seem like it has come out of nowhere, but it has been on the rise for a while. I argue that economic history and economic theory both provide ample grounds for anticipating that advanced stages of economic globalization would produce a political backlash. While the backlash may have...

Using data from the 2010-2014 American Community Survey, we use a procedure suggested by Capps et al. (2015) to identify refugees from the larger group of immigrants to examine the outcomes of refugees relocated to the U.S. Among young adults, we show that refugees that enter the U.S. before age...

This paper provides a mathematical foundation for independent random matching of a large population, as widely used in the economics literature. We consider both static and dynamic systems with random mutation, partial matching arising from search, and type changes induced by matching. Under...
