We develop a method for identifying and quantifying the fiscal channels that help finance government spending shocks. We define fiscal shocks as surprises in defense spending and show that they are more precisely identified when defense stock data are used in addition to aggregate macroeconomic...

Prior to the subprime crisis, mortgage brokers originated about 65% of all subprime mortgages. Yet little is known about their behavior during the runup to the crisis. Using data from New Century Financial Corporation, we find that brokers earned an average revenue of $5,300 per funded loan. We...

We measure credit risk premia - prices for bearing corporate default risk in excess of expected default losses - using Markit CDS and Moody's Analytics EDF data. We find dramatic variation over time in credit risk premia, with peaks in 2002, during the global financial crisis of 2008-09, and in...

The past two decades have seen a rapid increase in Private Equity (PE) investment in healthcare, a sector in which intensive government subsidy and market frictions could lead high-powered for-profit incentives to be misaligned with the social goal of affordable, quality care. This paper studies...

Firms often exploit loopholes in government contracts to boost revenues. The welfare consequences of this behavior depend on how firms use the marginal windfall dollar, yet little evidence exists to guide policymakers. This paper studies how hospitals allocated over $3 billion obtained from...

Privatization has been shown to increase growth and profitability of public firms. However, effects on consumers are understudied. We study potential trade-offs in the US hospital sector where public control declined by 42% over 1983-2019. Private operators may improve hospitals' financial...

Medicare has increased the use of performance pay incentives for hospitals, with the goal of increasing care coordination across providers, reducing market frictions, and ultimately to improve quality of care. This paper provides new empirical evidence by using novel operations and claims data...

Between 2000 and 2020, the share of US hospital bed capacity under multi-unit firms (systems) increased from 58% to 81% - a rapid corporatization of a sector with $1.3 trillion in annual spend. However, little is known about how system ownership affects hospital profitability and quality. We...

Voluntary participation is a central feature of reforms being tested across US healthcare. Allowing choice can enhance effects if participants sort on unobserved treatment gains. However, selection may also bias program evaluation, misleading policymakers. We study this trade-off in the case of...
