After having built private networks of knowledge, firms are aware of users' personal data and are capable of creating systems to sort people into groups. The potential of powerful and opaque algorithms to create discriminatory biases has been widely acknowledged, and there is no explanation...

The empirical literature on employer learning assumes that employers learn about unobserved ability differences across workers as they spend time in the labor market. This article describes testable implications that arise from this basic hypothesis and how they have been used to quantify the...

This paper suggests that skill accumulation through past work experience, or "learning-by-doing", can provide an important propagation mechanism for initial shocks, as the current labor supply affects future productivity. Our econometric analysis uses a Bayesian approach to combine micro-level...

The paper examines the impact of skill transfer on economic growth. Even if there are the benefits of backwardness and the ability to absorb them, the South may not exploit them, because the skilled workers in the North are not willing to come to the South owing to their high opportunity cost....

To improve operational efficiencies while providing state of the art healthcare services, hospitals rely on IT enabled physician referral systems (IT-PRS). This study examines learning curves in an IT-PRS setting to determine whether agents achieve performance improvements from cumulative...
