The Impact of the Bio-terrorism Act on the Supply Chain and Firm Value
Bibliographic record
Abstract
On June 12, 2002, President Bush signed into law the Public Health Security and Bioterrorism Preparedness and Response Act of 2002. The Bioterrorism Act requires domestic firms and importers to register their agribusiness facilities with the U.S. government, to notify Homeland Security prior to shipment of agricultural products, and to keep records on the origination of agricultural inputs and the destination of agricultural outputs. Thus, the Act significantly altered the U.S. regulatory climate for both U.S. and foreign food industry firms who do business in the U.S. We present evidence that the passage of the Bioterrorism Act resulted in an average 3.2% decline in the market value of equity of domestic food industry firms. Cross-sectional analysis suggests that costs are increasing in the diversity of the firms’ supply chains. Contrary to the conclusions of prior research, we also find that the Bioterrorism Act does not constitute a non-tariff barrier to Canadian food firms. We base this conclusion on the fact that the negative wealth effects for U.S. firms are similar in magnitude to those previously reported for Canadian firms.

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.
