This paper investigates a real-business-cycle economy that features dispersed information about the underlying aggregate productivity shocks, taste shocks, and, potentially, shocks to monopoly power. We show how the dispersion of information can (i) contribute to significant inertia in the...

We examine how credit constraints affect the cyclical behavior of productivity-enhancing investment and thereby volatility and growth. We first develop a simple growth model where firms engage in two types of investment: a short-term one and a long-term productivity-enhancing one. Because it...

We introduce a neoclassical growth economy with idiosyncratic production risk and incomplete markets. Each agent is an entrepreneur operating her own neoclassical technology with her own capital stock. The general equilibrium is characterized in closed form. Idiosyncratic production shocks...

Using microdata for adults from the 1987-2000 years of the Behavioral Risk Factor Surveillance System, I show that smoking and height-adjusted weight decline during temporary economic downturns while leisure-time physical activity rises. The drop in tobacco use occurs disproportionately among...

This study uses aggregate data for 23 OECD countries over the 1960-1997 period to examine the relationship between macroeconomic conditions and fatalities. The main finding is that total mortality and deaths from several common causes increase when labor markets strengthen. For instance,...

This paper investigates the relationship between macroeconomic conditions, alcohol use, and drinking problems using individual-level data from the 1987-1999 years of the Behavioral Risk Factor Surveillance System. We confirm the procyclical variation in overall drinking identified in previous...

This study examines the relationship between economic conditions and health. Fixed-effect models are estimated using state level data for the 1972-1991 time period. Health is proxied by total and age- specific mortality rates, as well as by 10 particular causes of death. Total mortality and nine...

We dissect the comovement patterns of the macroeconomic data, identify a single shock that accounts for the bulk of the business-cycle volatility in the key quantities, and use its empirical properties to appraise parsimonious models of the business cycle. Through this lens, the data appears to...

We consider a stationary setting featuring forward-looking behavior, higher-order uncertainty, and learning. We obtain an observational equivalence result that recasts the aggregate dynamics of this setting as that of a representative-agent model featuring two distortions: myopia in the sense of...

The notion that business cycles are driven by demand shocks is subtle. I first review some of the conceptual and empirical challenges faced when trying to accommodate this notion in micro-founded, general-equilibrium models. I next review my own research, which sheds new light on the observed...
