  • In this final rule, OSHA is modifying its Standard (HCS) to conform to the United Nations' Globally Harmonized System of Classification and Labelling of Chemicals (GHS). OSHA has determined that the modifications will significantly reduce costs and burdens while also improving the quality and consistency of information provided to employers and employees regarding chemical hazards and associated protective measures. Consistent with the requirements of Executive Order 13563, which calls for assessment and, where appropriate, modification and improvement of existing rules, the Agency has concluded this improved information will enhance the effectiveness of the HCS in ensuring that employees are apprised of the chemical hazards to which they may be exposed, and in redu...

  • This study examines the cause of the Melamine Scandal, a major food safety crisis that took place in China in 2008. Drawing upon game theory, it focuses on the interplay between two major stakeholders in the process of enforcement of food safety regulations-the regulatory agency of the government, and the public, which consumes manufactured or processed food products. The authors found that the Melamine Scandal was a symptom of malfunctioning of the mechanism of food safety controls in China. The reason for the lack of efficient regulations was that the compensation structure failed to provide the regulators enough incentive to perform their duty.

  • Based on the analysis of the specific environment in which football clubs compete, this paper presents a comparative institutional analysis of three paradigmatic structures of football club governance: privately owned football firms, public football corporations (stock corporations with dispersed ownership) and members' associations with an own legal personality (Verein). Against the background that "spending power" is the main driver of competitive advantage for clubs in the overinvestment environment of European football, the governance structure of the privately owned football firm exhibits superior abilities to tap sources of funding and channel them into playing talent. The results of the analysis are applied to current developments in German and English football and to recent init...
