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.
We provide an innovative methodological contribution to the measurement of returns on infrequently traded assets using a novel approach to repeat-sales regression estimation. The model for price indices we propose allows for correlation with other markets, typically with higher liquidity and high frequency trading. Using the new econometric approach, we propose a monthly art market index, as well as sub-indices for impressionist, modern, post-war, and contemporary paintings based on repeated sales at a monthly frequency. The correlations enable us to update the art index via observed transactions in other markets that have a link with the art market.
Organizational, economic, and technology forces are encouraging organizations to experiment with new ways to develop their strategic priorities (Chesbrough & Appleyard, 2007). One such new approach is Open Strategy (OS), an approach that increasingly relies on the use of online digital platforms. OS refers to the process by which an organization’s strategy for the future is developed in a planned or inadvertent manner with more transparency for all stakeholders and/or inclusion of different stakeholders compared to conventional strategy-making processes (Hautz et al., 2017; Mack & Szulanski, 2017; Whittington et al., 2011).
Entrepreneurs making decisions under uncertainty are encouraged to evaluate their initial ideas through hypothesis testing, but entrepreneurial approaches vary in their emphasis on ex-ante theory development prior to collecting evidence. In this paper, we examine whether and how entrepreneurs benefit from adopting an evidence-based approach or a theory-and-evidence-based approach to decision-making.
We hypothesized that individuals in cultures typified by lower levels of relational mobility would tend to show more attention to the surrounding social and physical context (i.e., holistic vs. analytic thinking) compared with individuals in higher mobility cultural contexts. Six studies provided support for this idea. Studies 1a and 1b showed that differences in relational mobility in cultures as diverse as the U.S., Spain, Israel, Nigeria, and Morocco predicted patterns of dispositional bias as well as holistic (vs. analytic) attention.
The contemporary workplace is characterized by transience: Organizational members frequently turn over and careers span multiple organizations. Consequently, workplace friendships that were once close become less close and intimate, that is they become peripheral and can deteriorate. While research has examined the benefits for employees who move on to new opportunities, less clear is how stayers, or employees who remain behind in the work setting, are affected. To understand stayers’ experiences and how they manage, we draw on theories of belongingess and to offer a three-part episodic process model, which explains how stayers’ engagement in the task and social domains are influenced.
Voting outcomes can differ from underlying preferences due to strategic selection into voting. One explanation for such selection effects is lower participation of shareholders with popular preferences (free-rider effect) relative to those with unpopular preferences (underdog effect). We illustrate these effects in a rational choice model in which the voting participation decision depends on the probability of being pivotal and the costs and benefits of voting.
Worker attrition is a costly and operationally disruptive challenge throughout the world. Although large bodies of research have documented drivers of attrition and its operational consequences, managers still lack an integrated approach to understanding attrition and making decisions to address it on a forward-going basis.
This study examines whether the disclosure of critical audit matters (CAMs) in the expanded audit report in China is associated with an increase in audited financial statement quality. Specifically, we predict and find that timeliness of goodwill impairment by Chinese listed firms increased after the disclosure of CAMs related to goodwill.
Don’t believe the myth that a startup with a single founder is bound for trouble. According to a piece in the Harvard Business Review by UNC Kenan-Flagler Business School Professors Chris Bingham and Brad Hendricks, and UC-Irvine Paul Merage School of Business Professor Travis Howell, solo founders succeed with critical assistance from people and organizations who aren’t official co-founders and don’t require substantial equity.
European economies are now dominated by services, and virtually all companies view service as critical to retaining their customers today and in the future. This European edition provides students with a complete introduction to the unique marketing challenges that services present. Guiding students to recognize and understand these special characteristics, the text also explores frameworks for developing and implementing service strategies for competitive advantage across a wide array of industries.
This trial will provide evidence on the impact of a behavioral intervention to implement huddles as a key component of team-based care models. Knowledge gained from this trial will be critical to broader deployment and successful implementation of team-based care models.
In 2008, the majority of U.S. airlines began charging for the second checked bag, and then for the first checked bag. One of the often cited reasons for this action by the airlines’ executives was that this would influence customers to travel with less baggage and thus improve cost and operational performance.
Negotiation role-playing simulations are among the most effective and widely used methods for teaching and conducting research on negotiations. Teachers and researchers can either license a published, “off-the-shelf” simulation or write their own custom “bespoke” simulation.
Academics, politicians, and journalists are often highly critical of U.S. firms for holding too much cash. Cash holdings are stockpiled free-cash flow and incur substantial opportunity costs from the perspectives of economics. However, behavioral theory highlights the benefits of cash holdings as fungible slack resources facilitating adaptive advantages.
Measuring the impact of political risk on investment projects is one of the most vexing issues in international business. One popular approach is to assume that the sovereign yield spread captures political risk and to augment the project discount rate by this spread. We show that this approach is flawed. While the sovereign spread is influenced by political risk, it also reflects other risks that are likely included in the valuation analysis — leading to the double counting of risks. We propose to use “political risk spreads” to undo the double counting in the evaluation of international investment projects.
Purpose ‐ The purpose of this paper is to propose a conceptual framework ‐ the 4V model ‐ for better understanding how global brands create firm value. Organized around the global brand value chain, the 4V model includes four sets of value-creating activities: first, valued brands; second, value sources; third, value delivery; and fourth, valued outcomes. Design/methodology/approach ‐ The approach is conceptual with illustrative examples.
In this paper we examine the prevalence of data, specification, and parameter uncertainty in the formation of simple rules that mimic monetary policymaking decisions. Our approach is to build real-time data sets and simulate a real-time policy-setting environment in which we assume that policy is captured by movements in the actual federal funds rate, and then to assess what sorts of policy rule models and what sorts of data best explain what the Federal Reserve actually did.
