In this paper, I use anecdotal evidence and logical reasoning to suggest that, despite the use of an extensive database, it is not possible to conclude that passage of the Sarbanes Oxley Act did not have an impact on companies' delisting decisions. Moreover, the instrumental variables used to proxy for SOX effects are too weak and suffer from a significant endogeneity problem given that passage of SOX was driven by many of the economic and control problems that are used to control for market and company factors.

Health is a major component of well-being and quality of life (QOL) and an increasingly costly one. We examine the role of employers for promoting QOL. A meta-analysis examines the impact of fifty well-being programs, which address six health issues and use seven marketing approaches. The analysis indicates that well-being programs and marketing approaches significantly improve employee health and depend on company size and employee gender. Results, based on sixty studies, show there is significant opportunity to efficiently tailor corporate health programs.

We consider a novel variant of the perishable inventory profit management problem faced by a firm that sells a fixed inventory over a finite horizon in the presence of price-adjustment costs. In economics literature, such price-adjustment costs are widely studied and are typically assumed to include a fixed component (e.g., advertising costs), an inventory-dependent component (e.g., inventory relabeling costs), as well as a component that depends on the magnitude of the price adjustment (e.g., cognitive and coordination managerial costs).
