How is a developing country affected by its odious government's ability to borrow in international markets? We examine the dynamics of a country's growth, consumption, and sovereign debt, assuming that the government is myopic and wants to maximize short-term, socially unproductive, spending....

Recent work highlights a falling entry rate of new firms and a rising market share of large firms in the United States. To understand how these changing firm demographics have affected growth, we decompose productivity growth into the firms doing the innovating. We trace how much each firm...

We study private equity in a dynamic general equilibrium model and ask two questions: (i) Why does the investment of venture funds respond more strongly to the business cycle than that of buyout funds? (ii) Why are venture funds returns higher than those of buyout? On (i), venture brings in new...

We review the evidence that artificial intelligence (AI) is having a large effect on the economy. Across a variety of statistics--including robotics shipments, AI startups, and patent counts--there is evidence of a large increase in AI-related activity. We also review recent research in this...

This paper shows that social capital increases economic growth by raising government investment in human capital. We present a model of stochastic endogenous growth with imperfect political agency. Only some people correctly anticipate the future returns to current spending on public education....

This paper demonstrates theoretically that a financial shock can have very persistent effects on international trade. Motivation is taken from the aftermath of the dramatic trade collapse in 2008-9, which despite a substantial recovery, has left a persistently slower growth rate in trade. We...

Population growth has declined markedly in almost all major economies since the 1970s. We argue this trend has important consequences for the process of firm dynamics and aggregate growth. We study a rich semi-endogenous growth model of firm dynamics, and show analytically that a decline in...

This paper connects two salient economic features: (i) Fiscal shocks have asymmetric effects across business cycle phases (Gechert et al., 2019); (ii) Okun's coefficient is time varying and may be unstable. The intertwined dynamic behavior of fiscal shocks and unemployment-output trade-offs are...

Partner selection is a vital feature of human behavior with important consequences for individuals, families, and society. Hypergamy occurs when a husband's earning capacity systematically exceeds that of his wife. We provide a theoretical framework that rationalizes hypergamy even in the...

This paper studies the prevalence and nature of zero-hours contracts (ZHCs) in the UK labour market. The headline count of ZHC workers based on the Labour Force Survey has long underestimated and continues to underestimate the number of workers in ZHC or ZHC-like jobs. ZHC jobs and workers are...
