This paper proposes a tractable framework to analyze fiscal space and the dynamics of government debt, with a possibly binding zero lower bound (ZLB) constraint. Without the ZLB, a greater primary deficit unambiguously raises debt. However, debt need not explode: When R G - φ, where φ is the...

We propose a theory of indebted demand, capturing the idea that large debt burdens by households and governments lower aggregate demand, and thus natural interest rates. At the core of the theory is the simple yet under-appreciated observation that borrowers and savers differ in their marginal...

Rising income inequality since the 1980s in the United States has generated a substantial increase in saving by the top of the income distribution, which we call the saving glut of the rich. The saving glut of the rich has been as large as the global saving glut, and it has not been associated...

Brazil experienced one of the most severe recessions in its history from 2014 to 2016. Following a pattern shown for previous economic downturns in other countries, the Brazilian recession was preceded by a substantial increase in household debt from 2003 to 2014. This study utilizes a novel...

This study provides a new theoretical result that low interest rates encourage market concentration by raising industry leaders' incentive to gain a strategic advantage over followers, and this effect strengthens as the interest rate approaches zero. The model provides a unified explanation for...

Do low interest rates contribute to the rise in market concentration? Using data on firm financials and high frequency monetary policy shocks, we find that falling interest rates disproportionately benefit industry leaders, especially when the initial interest rate is already low. Falling rates...

From 2011 to 2014, the Brazilian government conducted a heavily advertised major credit expansion program through government banks as part of its effort to stimulate the economy. Using administrative data on individual-level borrowing and spending, we find that the program led to a substantial...

The County Business Pattern ("CBP") files contain employment and establishment counts for detailed industry codes covering all counties in the United States. The contribution of this project is to digitize, clean, and prepare the CBP files from 1946-1974. We also apply the methods developed in...

Academic research, government inquiries, and press accounts show extensive mortgage fraud during the housing boom of the mid-2000s. We explore a particular type of mortgage fraud: the overstatement of income on mortgage applications. We define "income overstatement" in a zip code as the growth...

Most government expenditure is on goods that yield primarily private benefits, such as education, pensions, and healthcare. We argue that markets are most advantageous in areas where high-powered incentives are desirable, but in areas where high-powered incentives stimulate unproductive...
