Abstract

This paper examines monthly earnings volatility and its transmission to household earnings volatility using Norwegian data on the universe of monthly pay histories. We document substantial month-to-month earnings changes: within a job, while over one-quarter of months have no earnings changes, another quarter have at least a 23% change. Accounting for multiple jobs and non-employment increases volatility, while aggregating to households reduces volatility by 12-35%. Event studies around job loss and couple formation, along with decomposition and bounding exercises, show that most of this decline reflects pooling effects rather than sorting or responses to shocks.
