Abstract
Construction labor shortages constrain project-level objectives and national development plans. The goal of this study is to utilize the lagged effects of macroeconomic conditions as early warning signs of construction labor shortages. To this end, the authors adopted a methodology, encompassing (1) retrieval of publicly available data and preprocessing of construction labor shortage as the target variable and macroeconomic measures as the explanatory variables, (2) identification of short-term associations between shortages and economic cycles using the Granger causality test, (3) examination of long-term relationships between labor shortages and economic conditions using the Johansen cointegration test, and (4) estimation of the impacts of economic conditions on labor shortages using the fixed-effects models. Results show that in the United States and Canada, interest rates and exports are the most significant leading indicators of construction labor shortages, with lags ranging from 12 to 15 months. Panel data analysis in the European Uinon and the United Kingdom reveals that a 1% increase in imports and building permits leads to increases in construction job vacancies by 1.19 and 0.63%, respectively, five quarters later. Findings highlight that by analyzing lagged macroeconomic indicators, construction practitioners can leverage the timely prioritize the strategies to mitigate labor shortages.

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 it
