摘要

Regulation of exposure to chemicals in the United States has become a topic of speculation. Certainly, this column has contributed to the cacophony. On March 20, the U.S. Department of Labor's Occupational Safety and Health Administration (OSHA) finally released the long-in-the-making revised Hazard Communication Standard (HCS). It's expensive to produce valid and accepted permissible exposure limits (PELs) for at least two reasons. First, at least four years are needed to organize, complete, and peer-review valid environmental, safety, and heath studies upon which the limits are based. Second, the data must be reviewed and published in an unbiased manner

7. We develop a sequential trade model of Iceberg order execution in a limit order book. The Iceberg-trader has the freedom to expose his trading intentions or (partially) shield the true order size against other market participants. Order exposure can cause drastic market reactions (“market impact”) in the end leading to higher transaction costs. On the other hand the Iceberg trader faces a loss-in-priority when he hides his intentions, as most electronic limit order books penalize the usage of hidden liquidity. Thus the Iceberg-trader is faced with the problem to find the right trade-off. Our model provides optimal exposure strategies for Iceberg traders in limit order book markets. In particular, we provide a range of analytical statements that are in line with recent empirical findings on the determinants of trader’s exposure strategies. In this framework, we also study the market impact also market impact of limit orders. We provide optimal exposure profiles for a range of hightech stocks from the US SP500 and how they scale with the state-of-the-book. We finally test the Iceberg’s performance against the limit orders and find that Iceberg orders can significantly enhance trade performance by up to 60. [O] . Gökhan Cebiro˜glu, Ulrich Horst 100
