Concrete and Cement Additives Antitrust Litigation

The causation theory in MDL-3097 involves the allegation that price-fixing and market sharing among dominant manufacturers of concrete and cement additives artificially inflated prices. This collusion disrupted normal competitive dynamics, leading to increased costs for purchasers and broader market distortions. Economically, the conspiracy caused a pass-through effect, raising construction costs and delaying projects, which adversely impacted the construction industry and end-users. Legally, the case hinges on establishing that the defendant's conduct was a substantial cause of the injury, with the court analyzing proximate causation and economic harm caused by the collusion.
