Tacit Collusion in Markets Under Regulatory Threat: The Effect of Multimarket Contact on Pricing Strategies

Journal of Management Studies, EarlyView.
Abstract Firms under regulatory threat often have a collective interest in influencing policy outcomes through market behaviour. However, when coordination is prohibited and collective benefits are non‐excludable, such efforts are constrained by coordination and outcome uncertainty.

Effect of substructure fabrication method and design on the fracture resistance properties of metal–ceramic restorations

Journal of Prosthodontics, EarlyView.
Abstract Purpose In metal–ceramic restorations, the substructure fabrication method and design may affect the prognosis of the prosthesis. This study evaluated and compared the fracture resistance of metal–ceramic restorations fabricated with different substructure fabrication methods using two different alloy powders and designs.
