This paper reviews the literature on firm wage differences and the fixed effects methods
typically used to measure these differences. High wage firms tend to be more productive …

We develop a model of size-based market power in a frictional labour market. In the
canonical search environment, competition for workers is encoded in outside options. In our …

We study the extent to which employer heterogeneity affects gender gaps in earnings across
the distribution, over time, and over the life cycle, accounting for cohort effects. Using a …

Using novel matched employer-employee register data with firm-level information on the
introduction of industrial robots, this paper analysis the impact of robots on the wages of …

Using rich administrative and household survey data spanning 34 years from 1985 to 2018,
we document a series of new facts on earnings inequality and dynamics in a develo** …

This paper uses a revealed preference approach applied to administrative data from
Washington to document and characterize work-hour constraints. Workers have limited …

Software represents a major and fast-growing share of firms' capital investment, impacting
demand for labor and what workers do on their jobs. Using US Census Bureau panel data …

Recent studies attribute the rise in wage inequality primarily to widening pay disparities
between rather than within firms. I develop a novel theory to quantitatively explain this fact …

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 …
