This study examines "tunneling" practices through which health care providers covertly extract profit by making inflated payments for goods and services to commonly-owned related parties. While incentives to tunnel exist across sectors, health care providers may find it uniquely advantageous to...

Good data on the size and composition of the independent contractor workforce are elusive, with household survey and administrative tax data often disagreeing on levels and trends. We carried out a series of focus groups to learn how self-employed independent contractors speak about their work....

What is the role of startups within the innovation ecosystem? Since 2000, startups have grown in their share of commercializing research from top U.S. universities; however, prior work has little to say on the particular advantages of startup ventures in the innovation process relative to more...

Private equity (PE) plays an increasingly important role in the modern US economy. However, its impacts on owned-firms are incompletely understood. We exploit a historically large leveraged buyout of a national hospital chain to examine how the full life cycle of PE influences hospital-level...

Firm-to-firm connections in domestic and international production networks play a fundamental role in economic outcomes. Firm heterogeneity and the sparse nature of firm-to-firm connections implicitly discipline network structure. We find that a large group of well-established statistical...

This paper develops a new model with heterogeneous firms under perfect competition in a Heckscher-Ohlin-Samuelson setting. We show that trade need not make selection in the comparative advantage sector stricter as suggested by earlier work. Selection is driven by the capital intensity in entry...

The impact of shocks in dynamic environments depends on how forward-looking agents anticipate the path of future fundamentals that shape their decisions. We incorporate flexible beliefs about future fundamentals in a general class of dynamic spatial models, allowing beliefs to be evolving,...

We provide a spatial theory of clean growth to assess the global impact of the rise of renewable energy. We model the details of the combined production and transmission network of electricity ("the grid") that determine the supply and losses of energy in space. The local rate of clean energy...

We review theoretical and empirical work on the economic effects of the United States and China trade relations during the last decades. We first discuss the origins of the China shock, its measurement, and present methods used to study its economic effects on different outcomes. We then focus...

The legitimacy of the world trading system is under growing attack, as challenges to its conformity with norms of fairness and social justice are increasingly voiced by citizens and their governments around the world. Taking a novel "bottom up" approach to concerns for fairness, we show how...
