A new Keynesian analysis of industrial employment fluctuations

This paper describes a model with sticky prices, search frictions and hours-clearing wages that provides firm differentiation across several dimensions: price, output, wage, employment and hours per worker. The connection between pricing and hiring decisions results in firm-level employment fluctuations that depend upon sticky prices, search costs, demand elasticity and labor supply elasticity. The calibrated model is able to match average US industrial employment volatility when assuming a small industrial size, providing one possible answer to Shimer (2005a)’s puzzle.
