Against Regulatory Stimulus, Erik F. Gerding

Publications

With political constraints on fiscal responses and monetary policy confronting the zero lower bound, policymakers may be tempted to turn to financial deregulation as a tool to stimulate economic growth in a recession, a strategy I label “regulatory stimulus.” This article creates a framework for answer two questions: first, whether and when regulatory stimulus is effective in promoting macroeconomic growth, particularly in a severe recession or liquidity trap; and second, if regulatory stimulus is effective, whether it is worth the potential trade-offs in terms of longer-term macroeconomic policy objectives.

Ultimately, I find grounds for skepticism that financial deregulation can effectively …

Disability Law And The Case For Evidence-Based Triage In A Pandemic, Govind Persad

Publications

This Essay explains why model policies proposed or adopted in response to the COVID-19 pandemic that allocate scarce medical resources by using medical evidence to pursue two core goals—saving more lives and saving more years of life—are compatible and consonant with disability law. Disability law, properly understood, permits considering medical evidence about patients’ probability of surviving treatment and the quantity of scarce treatments they will likely use. It also permits prioritizing health workers, and considering patients’ post-treatment life expectancy. These factors, when based on medical evidence and not inaccurate stereotypes, are legal to consider even if they disadvantage some patients …

Creating Diagnostic Assessments: Automated Distractor Generation With Integrity, Darryl Chamberlain, Russell Jeter

Publications

The goal of this paper is to propose a new method to generate multiple-choice items that can make creating quality assessments faster and more efficient, solving a practical issue that many instructors face. There are currently no systematic, efficient methods available to generate quality distractors (plausible but incorrect options that students choose), which are necessary for multiple-choice assessments that accurately assess students’ knowledge. We propose two methods to use technology to generate quality multiple-choice assessments: (1) manipulating the mathematical problem to emulate common student misconceptions or errors and (2) disguising options to protect the integrity of multiple-choice tests. By linking …

Explainable Ai Using Knowledge Graphs, Manas Gaur, Ankit Desai, Keyur Faldu, Amit Sheth

Publications

During the last decade, traditional data-driven deep learning (DL) has shown remarkable success in essential natural language processing tasks, such as relation extraction. Yet, challenges remain in developing artificial intelligence (AI) methods in real-world cases that require explainability through human interpretable and traceable outcomes. The scarcity of labeled data for downstream supervised tasks and entangled embeddings produced as an outcome of self-supervised pre-training objectives also hinders interpretability and explainability. Additionally, data labeling in multiple unstructured domains, particularly healthcare and education, is computationally expensive as it requires a pool of human expertise. Consider Education Technology, where AI systems fall along a …
