Did Covid-19 Change Life Insurance Offerings?, Timothy F. Harris, Aaron Yelowitz, Charles J. Courtemanche

Institute for the Study of Free Enterprise Working Papers

The profitability of life insurance offerings is contingent on accurate projections and pricing of mortality risk. The COVID-19 pandemic created significant uncertainty, with dire mortality predictions from early forecasts resulting in widespread government intervention and greater individual precaution that reduced the projected death toll. We analyze how life insurance companies changed pricing and offerings in response to COVID-19 using monthly data on term life insurance policies from Compulife. We estimate event-study models that exploit well-established variation in the COVID-19 mortality rate based on age and underlying health status. Despite the increase in mortality risk and significant uncertainty, we find limited …

Resilience Mediates The Relationship Between Socio-Cognitive Mindfulness And Perceived Stress In Academic Middle Managers In Higher Education, Rachel R. Slaymaker

Electronic Theses and Dissertations

Faculty, staff, and administrators in higher education have experienced rising stress levels due to an increasingly turbulent environment amid constant change and uncertainty. In particular, academic middle managers experience increasingly high demands and significant stressors in the ever-changing landscape of higher education. Most research that addresses stress among academic middle managers has focused on the management of stressors and emphasized the need for additional training and technical support rather than how to address adaptive challenges. However, emerging research has provided promising evidence of the positive effects of mindfulness in reducing the perception of stress and enhancing resilience, both of which …

U.S. Settler Colonialism, White Supremacy, And The Racially Disparate Impacts Of Covid-19, Monika Batra Kashyap

Faculty Articles

This Essay contextualizes the racially disproportionate impacts of COVID-19 in the United States within a framework of settler colonialism in order to broaden the understanding of how structural inequality is produced, imposed, and maintained. A settler colonialism framework recognizes that the United States is a present-day settler colonial society whose laws, institutions and systems of governance continue to reenact the three processes upon which the United States was built—Indigenous elimination, anti-Black racism, and immigrant exploitation. This Essay connects these foundational processes—and their underlying White supremacist logics—to the disparate health impacts of COVID-19 on Indigenous, Black, and immigrant of color communities …

The Potential Impacts Of Covid-19 On The Global Value Chains: Gvc Positioning And Linkages, Gerald Foong, Pao-Li Chang

Research Collection School Of Economics

Apart from the public health crisis entailed by the Coronavirus Disease 2019 (COVID-19) pandemic, it has also propagated a pandemic-induced economic shock globally. One transmission channel is via the inter-country linkages arising from the trade in intermediate inputs, which is a pertinent characteristic of global value chains (GVCs), and resulting in a "supply-chain contagion" as termed by Baldwin and Tomiura (2020). In this paper, we propose measures of bilteral downstreamness and upstreamness, the extent of a country's GVC participation, and the position of a country in GVCs by leveraging upon the gross export decomposition framework as laid out by Borin …

Covid-19 In Spain And India: Comparing Policy Implications By Analyzing Epidemiological And Social Media Data, Parth Asawa, Manas Gaur, Kaushik Roy, Amit P. Sheth

Publications

The COVID-19 pandemic has forced public health experts to develop contingent policies to stem the spread of infection, including measures such as partial/complete lockdowns. The effectiveness of these policies has varied with geography, population distribution, and effectiveness in implementation. Consequently, some nations (e.g., Taiwan, Haiti) have been more successful than others (e.g., United States) in curbing the outbreak. A data-driven investigation into effective public health policies of a country would allow public health experts in other nations to decide future courses of action to control the outbreaks of disease and epidemics. We chose Spain and India to present our analysis …
