UNC-Chapel Hill Professor Kurt Gray discusses how research can help us understand – and navigate – our rapidly changing professional and social lives.
Quantum computers are not yet up to the task of providing computational advantages for practical stochastic diffusion models commonly used by financial analysts. In this paper we introduce a class of stochastic processes that are both realistic in terms of mimicking financial market risks as well as more amenable to potential quantum computational advantages.
With the increasing prevalence of renewable energy supply contracts, utility suppliers are investing in new green sources and developing allocation policies of those to satisfy renewable targets required by customers. However, the variability of customer demand and the intermittency in supply complicates the supplier's decision process. In this paper, we address these challenges by formulating the utility supplier's problem as a two-stage stochastic program.
North Carolina’s 100 counties have experienced an uneven pattern of growth and development over the past decade or so, even during the pandemic, when the state was a magnet for migration. At one end, metropolitan and amenity-rich counties captured most of the growth between April 1, 2020, and July 1, 2021; at the other, 21 counties experienced net out-migration. Given these disparities, the Urban Investment Strategies Center offers an approach using targeted economic development strategies.
Our national security depends on a safe and secure food supply that is free of contamination, whether unintentional or the result of a terrorist act. In December 2006, Congress and the White House passed the Pandemic and All-Hazards Preparedness Act (PAHPA), establishing the goal of near-real-time electronic situational awareness to enhance early detection of, rapid response to, and management of public health threats in order to minimize their impact. Meeting this challenge for food safety depends on our ability to collect, interpret, and disseminate electronic information across organizational and jurisdictional boundaries. While events such as 9/11 have elevated the need to share critical intelligence related to security threats, these events have also promoted the proliferation of multiple data systems and tools whose lack of interoperability hinders effective intelligence gathering and timely response. Further, most of the public health and food safety informatics work in the United States—from early detection of food-related outbreaks by local and state health departments to confirmation by the Centers for Disease Control and Prevention (CDC) through “fingerprinting” of pathogenic contaminants—takes place at different local, state, and federal jurisdictional levels. As a result, large gaps exist in our ability to meet the challenge of food safety in the United States with regard to PAHPA.
The COVID-19 financial downturn will have short- and long-term effects on personal and consumer finance, as explored by a panel of Kenan Institute-convened experts during a press briefing held yesterday. The full recording of this briefing—along with a deeper-dive analysis on the specific implications of the downturn on personal retirement income by Kenan Institute Executive Director Greg Brown, is available in this week’s Kenan Insight.
We study the interaction of flexible capital utilization and depreciation for expected returns and investment of firms. Empirically, an investment strategy that buys (sells) equities with low (high) utilization rates earns 5% p.a.
Times are tough for universities. Leaders on campus are facing more pressure than ever – strategic, operational, and financial. How do we manage our administrative functions efficiently to free up resources for our core dual mission of teaching and research?
Extant literature highlights the importance of specific choices such as pricing and particular strategieslike “get big fast” for strategy in two-sided markets. Yet it leaves open how executives form a viable strategy in entrepreneurial settings, particularly when buyers, sellers, and product may be uncertain. With an inductive case study of 8 two-sided marketplace ventures in multiple industries, we developa theoretical framework that describes how entrepreneurs address this challenge: by focusing on successive strategic domains, beginning with supply.
This study provides evidence that nonbank institutional investors that participate in loan syndicates value inside information obtained through lending agreements with bellwether borrowers. The private information nonbank institutional investors obtain from lending relationships with bellwether firms can help identify trading opportunities in other public market securities. Thus, we predict and find that institutional investors compensate bellwether firms by charging a lower loan spread.
This study examines the antecedents and consequences of knowledge sharing and monitoring based governance strategies on emissions reduction. We theorize, and empirically test, the impact of supply base diversity in industry and geographic locations on the governance strategy choices. We find that sector and regional diversity both have a significant impact on emissions reduction strategies, yet their direct and interactive impacts are different. Regarding consequences, we find that engaging suppliers is associated with GHG emissions reduction for both buyers and suppliers.
We study the relation between trade credit, asset prices, and production-network linkages. Empirically, firms extending more trade credit earn 7.6% p.a. lower risk premiums and maintain longer relationships with customers.
As the digital revolution rages on, every business leader must become technology literate. This guide provides executives with an introduction to the technologies that are transforming our world.
We present a classical enhancement to improve the accuracy of the Hybrid variant (Hybrid HHL) of the quantum algorithm for solving linear systems of equations proposed by Harrow, Hassidim, and Lloyd (HHL). We achieve this by using higher precision quantum estimates of the eigenvalues relevant to the linear system, and a new classical step to guide the eigenvalue inversion part of Hybrid HHL.
Immigration is one of the most contentious policy issues, and Congress has for decades failed to make any significant legislative progress. The result is an incoherent policy landscape and serious operational challenges on the ground. At the same time, immigration and immigrant integration are critical to U.S. workforce growth, government fiscal solvency, and innovation. I discuss key findings from the economics literature and their implications for where to focus immigration reform efforts.
There is no doubt that the COVID-19 crisis has devastated the U.S. economy. But the particulars of this devastation are difficult to gauge, because unique aspects of the of the pandemic distort the data commonly used to assess such situations. In this Kenan Insight, we take a deep dive into the data to learn what it actually tells us about the economic impact of COVID-19, and suggest possibilities for a restart and recovery of the U.S. economy.
A pooled Public Use Microdata Sample File of the Census Bureau’s Annual American Community Survey (2011-2015) is used to (1) create a demographic profile of the nation’s older adult population; (2) develop an older adult household typology which encapsulates both generational dynamics and diverse living arrangements; and (3) identify older adults who face the greatest barriers to aging in place. Policies and strategies that support and facilitate successful aging in place for the most vulnerable older adults are discussed.
The COVID-19 pandemic has exposed vulnerabilities in many supply chains, none more so than the healthcare supply chain. What factors have contributed to the alarming lack of readily available healthcare resources in the wake of overwhelming need? And what can be done to prevent such a disconnect from happening again? Professor Brad Staats, faculty director of the UNC Center for the Business of Health, and UNC Kenan-Flagler Business School Professor Jay Swaminathan present the findings of their most recent supply chain research in this week’s Kenan Insight.
Much has been said (and rightly so) about the catastrophic effects of the COVID-19 pandemic. But there is another side to the crisis. It’s a story of hope, based on collaboration and innovation. As healthcare needs and economic hardships intensify, entrepreneurs around the globe are stepping up to create solutions that will not only address immediate needs, but also effect long-lasting change. A panel of Kenan Institute-convened experts discussed this surge of innovation in response to COVID-19 on April 7, 2020. The full recording of this press briefing–-along with a deeper-dive analysis on the drivers of innovation amid the crisis by UNC Kenan-Flagler Professors Mahka Moeen and Chris Bingham-–is available in this week’s Kenan Insight.
