Benders Decomposition for Production Routing under Demand Uncertainty

Abstract: The production routing problem (PRP) is a generalization of the inventory routing problem and concerns the production and distribution of a single product from a production plant to multiple customers using capacitated vehicles in a discrete- and finite-time horizon. In this study, we consider the stochastic PRP with demand uncertainty in two-stage and multistage decision processes. The decisions in the first stage include production setups and customer visit schedules, while the production and delivery quantities are determined in the subsequent stages. We introduce formulations for the two problems, which can be solved by a branch-and-cut algorithm. To handle a large number of scenarios, we propose a Benders decomposition approach, which is implemented in a single branch-and-bound tree and enhanced through lower-bound lifting inequalities, scenario group cuts, and Pareto-optimal cuts. For the multistage problem, we also use a warm start procedure that relies on the solution of the simpler two-stage prob...

Board Monitoring, Audit Committee Effectiveness, and Financial Reporting Quality: Review and Synthesis of Empirical Evidence

Abstract: We review and synthesize the results of empirical studies of associations between corporate oversight measures and financial reporting quality (FRQ). We examine two oversight components, board characteristics and audit committee characteristics. For each component, we summarize associations between variables contributing to monitoring effectiveness and three presumptive FRQ monitoring outcomes: (1) ex post consequences of low FRQ, such as financial reporting fraud; (2) earnings management measures, such as abnormal accruals; and (3) perceived informativeness of financial reports, manifest in earnings-returns associations, earnings response coefficients, and analyst perceptions of FRQ. Our classification scheme provides a coherent framework for synthesizing the implications of empirical findings, highlighting the role of different corporate governance variables in enhancing different aspects of FRQ. This synthesis has the potential to inform regulators, boards of directors, and forensic accountants who are concerned with improving the oversight of public corporations and reducing opportunities for managers and others to engage in financial fraud.

“And Who Are You?”: A Performative Perspective on Authority in Organizations

Abstract: As work and organizational realities become increasingly “post-bureaucratic,” the conventional and stable bases of a person’s authority—their position, their expertise, or the acquiescence of a sub...
