The Consumption-Tightness Puzzle

Working Paper: NBER ID: w12421

Authors: Morten O. Ravn

Abstract: This paper introduces a labor force participation choice into a labor market matching model embedded in a dynamic stochastic general equilibrium set-up with production and savings. The participation choice is modelled as a tradeoff between forgoing the expected benefits of being search active and engaging in costly labor market search. The model induces a symmetry in firms' and workers' search decision since both sides of the labor market vary search effort at the extensive margins. We show that this set-up is of considerable analytical convenience and that it gives rise to a linear relationship between labor market tightness and the marginal utility of consumption. We refer to the latter as the "consumption - tightness puzzle" because (a) it gives rise to a number of counterfactual implications, and (b) it is a robust implication of theory. Amongst the counterfactual implications are very low volatility of tightness, procyclical unemployment, and a positively sloped Beveridge curve. These implications all derive from procyclical variations in participation rates that follow from allowing for the extensive search margin.
