|November 2017||Children, Time Allocation and Consumption Insurance|
with Richard Blundell, Luigi Pistaferri: w24006
We consider the life cycle choices of a household that in each period decides how much to consume and how to allocate spouses' time to work, leisure, and childcare. In an environment with uncertainty, the allocation of goods and time over the life cycle also serves the purpose of smoothing marginal utility in response to shocks. We combine data on consumption, spouses' wages, hours of work, and time spent with children to estimate the sensitivity of consumption and time allocation to transitory and permanent wage shocks. These structural parameters describe the ability of household to self-insure in response to shocks. We find that behavioral responses to wage shocks depend on the presence of young children. We also find that labor supply cross-responses depend on three counteracting force...
|March 2017||What Drives Differences in Management?|
with Nicholas Bloom, Erik Brynjolfsson, Lucia Foster, Ron S. Jarmin, Megha Patnaik, John Van Reenen: w23300
Partnering with the Census we implement a new survey of “structured” management practices in 32,000 US manufacturing plants. We find an enormous dispersion of management practices across plants, with 40% of this variation across plants within the same firm. This management variation accounts for about a fifth of the spread of productivity, a similar fraction as that accounted for by R&D, and twice as much as explained by IT. We find evidence for four “drivers” of management: competition, business environment, learning spillovers and human capital. Collectively, these drivers account for about a third of the dispersion of structured management practices.
|October 2012||Consumption Inequality and Family Labor Supply|
with Richard Blundell, Luigi Pistaferri: w18445
In this paper we examine the link between wage inequality and consumption inequality using a life cycle model that incorporates household consumption and family labor supply decisions. We derive analytical expressions based on approximations for the dynamics of consumption, hours, and earnings of two earners in the presence of correlated wage shocks, non-separability and asset accumulation decisions. We show how the model can be estimated and identified using panel data for hours, earnings, assets and consumption. We focus on the importance of family labour supply as an insurance mechanism to wage shocks and find strong evidence of smoothing of males and females permanent shocks to wages. Once family labor supply, assets and taxes are properly accounted for their is little evidence of addi...

|July 2012||Really Uncertain Business Cycles|
with Nicholas Bloom, Max Floetotto, Nir Jaimovich, Stephen J. Terry: w18245
We propose uncertainty shocks as a new shock that drives business cycles. First, we demonstrate that microeconomic uncertainty is robustly countercyclical, rising sharply during recessions, particularly during the Great Recession of 2007-2009. Second, we quantify the impact of time-varying uncertainty on the economy in a dynamic stochastic general equilibrium model with heterogeneous firms. We find that reasonably calibrated uncertainty shocks can explain drops and rebounds in GDP of around 3%. Moreover, we show that increased uncertainty alters the relative impact of government policies, making them initially less effective and then subsequently more effective.
