The Inflationary Effects of Sectoral Reallocation
The COVID-19 pandemic has led to an unprecedented shift of consumption from services to goods. We study this demand reallocation in a multi-sector model featuring sticky prices, input-output linkages, and labor reallocation costs. Reallocation costs hamper the increase in the supply of goods, causing inflationary pressures. These pressures are amplified by the fact that goods prices are more flexible than services prices. We estimate the model allowing for demand reallocation, sectoral productivity, and aggregate labor supply shocks. The demand reallocation shock explains a large portion of ...

Does Unemployment Risk Affect Business Cycle Dynamics?
In this paper, I show that the decline in household consumption during unemployment spells depends on both liquid and illiquid asset positions. I also provide evidence that unemployment spells predict the withdrawal of illiquid assets, particularly when households have few liquid assets. Motivated by these findings, I embed endogenous unemployment risk in a two-asset heterogeneous-agent New Keynesian model. The model is consistent with the above evidence and provides a new propagation mechanism for aggregate shocks due to a flight-to-liquidity that occurs when unemployment risk rises. This ...

Time Averaging Meets Labor Supplies of Heckman, Lochner, and Taber
We incorporate time-averaging into the canonical model of Heckman, Lochner, and Taber (1998) (HLT) to study retirement decisions, government policies, and their interaction with the aggregate labor supply elasticity. The HLT model forced all agents to retire at age 65, while our model allows them to choose career lengths. A benchmark social security system puts all of our workers at corner solutions of their career-length choice problems and lets our model reproduce HLT model outcomes. But alternative tax and social security arrangements dislodge some agents from those corners, bringing ...

The State Dependent Effectiveness of Hiring Subsidies
The responsiveness of job creation to shocks is procyclical, while the responsiveness of job destruction is countercyclical. This new finding can be explained by a heterogeneous-firm model in which hiring costs lead to lumpy employment adjustment. The model predicts that policies that aim to stimulate employment by encouraging job creation, such as hiring subsidies, are significantly less effective in recessions: These are times when few firms are near their hiring threshold and many firms are near their firing threshold. Policies that target the job destruction margin, such as employment ...

Time Averaging Meets Labor Supplies of Heckman, Lochner, and Taber
We add endogenous career lengths to the Heckman, Lochner, and Taber (1998a) (HLT) model with its credit markets and within-period labor supply indivisibilities, all of which are essential features of Ljungqvist and Sargent (2006) “time-averaging.” A benchmark social security system puts all workers at corner solutions of their retirement decisions. That lets our model reproduce most outcomes in HLT’s model with its inelastic labor supply and mandatory retirement date for all types of workers. Eight types of workers are indexed by pairs of innate abilities and choices of education ...
