Abstract

Stochastic shocks to aggregate labor supply elasticity are introduced into a real-business-cycle setup augmented with a detailed government sector. The model is calibrated to Bulgarian data for the period following the introduction of the currency board arrangement (1999-2018). The quantitative importance of a stochastic aggregate labor supply elasticity parameter is investigated for the magnitude of the cyclical fluctuations in Bulgaria. The quantitative effect of such a stochasticity increases the variability of
hours, and lowers the correlation between hours and wages, and thus is found to be
quantitatively important for the labor market aspect of business cycles.
