April 2019Earnings Dynamics and Firm-Level Shocks
with Lisa Laun, Costas Meghir, Luigi Pistaferri: w25786
We use matched employer-employee data from Sweden to study the role of the firm in affecting the stochastic properties of wages. Our model accounts for endogenous participation and mobility decisions. We find that firm-specific permanent productivity shocks transmit to individual wages, but the effect is mostly concentrated among the high-skilled workers; firm-specific temporary shocks mostly affect the low-skilled. The updates to worker-firm specific match effects over the life of a firm-worker relationship are small. Substantial growth in earnings variance over the life cycle for high-skilled workers is driven by firms accounting for 44% of cross-sectional variance by age 55.
February 2017The Returns to Nursing: Evidence from a Parental Leave Program
with Martin B. Hackmann: w23174
Nurses comprise the largest health profession. In this paper, we measure the effect of nurses on health care delivery and patient health outcomes across sectors. Our empirical strategy takes advantage of a parental leave program, which led to a sudden, unintended, and persistent 12% reduction in nurse employment. Our findings indicate detrimental effects on hospital care delivery as indicated by an increase in 30-day readmission rates and a distortion of technology utilization. The effects for nursing home care are more drastic. We estimate a persistent 13% increase in nursing home mortality among the elderly aged 85 and older. Our results also highlight an unintended negative consequence of parental leave programs borne by providers and patients.
