Abstract
In an era of rapid technological advancements and macroeconomic shifts, worker reallocation
is necessary, yet responses to labor market shocks remain sluggish, making it crucial to identify
bottlenecks in occupational transitions to understand labor market dynamics and improve mo-
bility. In this study, we analyze French occupational data to uncover patterns of worker mobility
and pinpoint specific occupations that act as bottlenecks which impede rapid reallocation. We
introduce two metrics, transferability and accessibility, to quantify the diversity of occupational
transitions and find that bottlenecks can be explained by a condensation effect of occupations
with high accessibility but low transferability. Transferability measures the variety of transitions
from an occupation to others, while accessibility assesses the variety of transitions into an
occupation. We provide a comprehensive framework for analyzing occupational complexity and
mobility patterns, offering insights into potential barriers and pathways for efficient retraining
programs. We argue that our approach can inform policymakers and stakeholders aiming to
enhance labor market efficiency and support workforce adaptability.
