Labor market effects in the German‐Czech border region: An empirical study using the IAB employment sample (IABS)
Bibliographic record
Abstract
Abstract Using the IAB Employment Sample (IABS) covering 1980–2001, we investigate what impact the fall of the Iron Curtain has had on the skill structure of employment and wages in the western German districts neighboring the Czech Republic. The introduction of free trade and capital mobility in this region, which has one of the world's largest wage differentials, can be seen as a natural experiment. Even though full liberalization of the labor markets has not yet occurred, integration of product and capital markets should lead to significant shifts in economic activities. We presume that changes in skill and wage structures are particularly apparent in the regions situated immediately on the open border. Distinguishing three skill categories we obtain rather unexpected results. Though we observe a general shift from low‐skilled jobs towards skilled jobs and a convergence trend of border regions towards the national average, we do not find a special effect for the period after the opening of the border, neither concerning the skill structure nor the wage differentials.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
