Abstract

fetched live from OpenAlex

Demographic projections show the majority of OECD economies will see declines in their working-age populations in the coming decades. This is potentially problematic, since young workers account for a large share of net labor reallocation between growing and shrinking industries. To examine if sectoral reallocation costs are exacerbated by an aging population, we develop a three-sector perpetual youth search model with sector-specific human capital. Our model features two interconnected frictions: sectoral preference , which implies that only some workers are mobile across sectors, and a wage bargaining distortion , whereby mobile workers’ outside option of searching in the growing sector dampens the fall in shrinking sector wages, leading to rest unemployment. In our parameterized model, as population growth declines from 3 to − 1 percent, output losses from a one-time reallocation shock of 3 percentage points increase seven-fold to nearly 10 percent of annual GDP, and there are extended periods of high unemployment and low vacancies.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
