Neural-Progressive Hedging: Enforcing Constraints In Reinforcement Learning With Stochastic Programming, Supriyo Ghosh, Laura Wynter, Shiau Hong Lim, Duc Thien Nguyen

Research Collection School Of Computing and Information Systems

We propose a framework, called neural-progressive hedging (NP), that leverages stochastic programming during the online phase of executing a reinforcement learning (RL) policy. The goal is to ensure feasibility with respect to constraints and risk-based objectives such as conditional value-at-risk (CVaR) during the execution of the policy, using probabilistic models of the state transitions to guide policy adjustments. The framework is particularly amenable to the class of sequential resource allocation problems since feasibility with respect to typical resource constraints cannot be enforced in a scalable manner. The NP framework provides an alternative that adds modest overhead during the online phase. …

Conditions For Increased Fraud Risk: A Case Study By Restaurant Segment, Elizabeth A. Yost

Journal of Hospitality Financial Management

Risk factors leading to fraud is an important issue for restaurant operators. This paper identifies and evaluates the financial and non-financial characteristics of different restaurant segments through the lens of the fraud triangle. Using probit modeling and time series data from 2004 to 2014, it investigates different factors that significantly impact the increased risk of fraud in four types of restaurant segments—quick service, fast casual, casual dining, and fine dining. As such the findings of this study provide a better understanding of internal and external risk factors leading to increased fraud in the restaurant industry.

Perspectives On Regulating Systemic Risk, Steven L. Schwarcz

Faculty Scholarship

This book chapter, which synthesizes several of the author’s articles, attempts to provide useful perspectives on regulating systemic risk. First, it argues that systemic shocks are inevitable. Accordingly, regulation should be designed not only to try to reduce those shocks but also to protect the financial system against their unavoidable impact. This could be done, the chapter explains, by applying chaos theory to help stabilize the financial system. The chapter then focuses on trying to prevent excessive corporate risk-taking, which is one of the leading triggers of systemic shocks and widely regarded to have been a principal cause of the …

Time Diversification: Tool, Fallacy Or Both?, Ladd Kochman, Randy Goodwin

Ladd Kochman

It seems fair to conclude that time diversification is more nearly a fallacy than a tool. Total periodic returns based on random annual outcomes expose the practice of diversifying with time not only as unproductive but as extremely risky as well. Yet, as the contrived distribution of alternating returns of 30% and -10% demonstrated, it is impossible to completely reject the idea that risk can actually decrease over time.

The Relationship Of Cognitive Effort, Information Acquisition Preferences And Risk To Simulated Auditor–Client Negotiation Outcomes, Gary Kleinman, Dan Palmon, Kyunghee Yoon

Department of Accounting and Finance Faculty Scholarship and Creative Works

The auditor–client relationship is a legally-mandated relationship in which one party, the auditor, is hired and paid by the auditee (client) to inform third party stakeholders as to whether the client firm’s financial statements are presented in conformity with national financial accounting standards. When these statements do not meet the criteria for acceptable financial statements, a negotiation situation may arise in which the auditor is presumed to act in the best interests of shareholders and creditors who have no independent knowledge of the auditor’s findings. The client management may then feel forced to defend its numbers. The result is a …

Regulating Systemic Risk In Insurance, Daniel Schwarcz, Steven L. Schwarcz

Faculty Scholarship

As exemplified by the dramatic failure of AIG, insurance companies and their affiliates played a central role in the 2008 global financial crisis. It is therefore not surprising that the Dodd-Frank Act—the United States’ primary legislative re-sponse to the crisis—contained an entire title dedicated to insurance regulation, which has traditionally been the responsibility of individual states. The most important insurance-focused reforms in Dodd-Frank empower the Federal Reserve Bank to impose an additional layer of regulatory scrutiny on top of state insurance regulation for a small number of “systemically important” nonbank financial companies, such as AIG. This Article argues, however, that …

The Bankruptcy-Law Safe Harbor For Derivatives: A Path-Dependence Analysis, Steven L. Schwarcz, Ori Sharon

Faculty Scholarship

U.S. bankruptcy law grants special rights and immunities to creditors in derivatives transactions, including virtually unlimited enforcement rights. This article argues that these rights and immunities result from a form of path dependence, a sequence of industry-lobbied legislative steps, each incremental and in turn serving as apparent justification for the next step, without a rigorous and systematic vetting of the consequences. Because the resulting “safe harbor” has not been fully vetted, its significance and utility should not be taken for granted; and thus regulators, legislators, and other policymakers—whether in the United States or abroad—should not automatically assume, based on its …

Issue Brief: Saving By Mitigating, University Of Louisville, New England Environmental Finance Center

Sustainable Communities Capacity Building

Natural disasters can cause loss of life, inflict damage to buildings and infrastructure, and have devastating consequences for a community’s economic, social, and environmental well-being. Hazard mitigation means reducing damages from disasters.

Local governments have the responsibility to protect the health, safety, and welfare of their citizens. Proactive mitigation policies and actions help reduce risk and create safer, more disaster-resilient communities. Mitigation is an investment in your community’s future safety, equity, and sustainability.

The Impact Of Groups And Decision Aid Reliance On Fraud Risk Assessment., Anna Alon, Peggy Dwyer

Faculty Publications

The purpose of this paper is to investigate how the brainstorming component of Statement of Auditing Standards (SAS) No. 99 influences decision aid use and reliance, and the effectiveness of fraud risk assessment. The research framework links the influences of the fraud assessment setting and decision aid reliance. The hypotheses are tested in an experiment with two manipulated factors: setting (group or individual) and decision aid (provided or not provided). The results of the study provide insight on how the brainstorming impacts fraud risk assessment, decision aid use and decision aid reliance. The results show that groups using a decision …
