Economists have long held that bringing firms under the umbrella of a common ownership structure creates monopolistic conditions that reduce competition. We challenge this view by investigating competition between firms in a nuanced manner. We examine the competitive and performance implications of “common institutional ownership,” which occurs whe...

Hospitals in the United States (U.S.), and the healthcare industry as a whole, are experiencing major transformations that will likely affect every facet of our society. One such example is a federal regulation known as the Value‐Based Purchasing (VBP) program, which shifts hospital reimbursements for services rendered away from a fee‐for‐service m...

The traditional forecasting methods in the M&A data have three limitations: first, the outcome of M&A deal is an event with a small probability of failure, second, the consequences of misclassifying failure as success are much more severe than those of misclassifying success as failure, and third, the nonlinear and complex nature of the relationshi...

Research summary We propose that CEO dismissal can change the strategic decision‐making of CEOs at competing firms. Competitor CEOs will experience an increase in job insecurity, which motivates them to refrain from strategic risk taking. We also identify two key boundary conditions that shape the influence of CEO dismissal on competitor CEOs’ risk...

For many countries attempting to control the fast-rising number of coronavirus cases and deaths, the race is on to “flatten the curve,” since the spread of coronavirus disease 2019 (COVID-19) has taken on pandemic proportions. In the absence of significant control interventions, the curve could be steep, with the number of COVID-19 cases growing ex...

Over the past two decades, more than 11,000 U.S. counties have been impacted by natural disasters. This study investigates how banks and their depositors respond to such events using a difference-in-difference-in-differences (DDD) methodology combined with coarsened exact matching (CEM). Analyzing 1.3 million observations from 1999 to 2017, we find...

In this paper, we propose systematic approaches for learning imbalanced data based on a two-regime process: regime 0, which generates excess zeros (majority class), and regime 1, which contributes to generating an outcome of one (minority class). The proposed model contains two latent equations: a split probit (logit) equation in the first stage an...

Unlike industrial sectors, quality of care is of critical importance in the healthcare sector. Accordingly, incorporating environmental sustainability into healthcare services poses a unique challenge since hospitals must strike a balance among service quality (i.e., clinical quality and patient experience), cost efficiency, and environmental footp...

We describe an exploratory study examining the effectiveness of an interactive app and a novel training process for improving calibration and reducing overconfidence in probabilistic judgments. We evaluated the training used in the app by conducting an American college football forecasting tournament involving 153 business school students making 52...

Outliers in financial time series data are different from that in cross-sectional data in terms of the treatment and the detection. First, outliers in time series can be the focus of analysis itself, such as outliers in margin debt to indicate an overheating market. Second, the outlier detection in time series should be accompanied by decomposition...

We extend the existing literature on bank capital structure by applying a time-varying parameter model to the partial adjustment framework. This model allows one to obtain a more timely and on-going assessment of bank behavior in adjusting the capital ratio to its optimal or target level. The estimated time-varying rate of capital adjustment indica...

We examine the effects of banks’ client stock ownership structure on their governance mechanism, risk taking, and systemic risk in the financial system. We apply a dyadic level of analysis to provide new insights into the relevance of such cross‐ownership as an effective monitoring mechanism and as a source of interconnectedness between and among f...

Emergency departments (EDs) are an integral part of many acute care hospitals. Recently, however, hospitals have been increasingly experimenting with a new type of ED, for example, freestanding emergency departments (FSEDs). These are EDs that are physically separate from acute care hospitals but provide many of the same services provided by tradit...

This study examines the often-overlooked effect of product category type—high- vs. low-priced, high- vs. low-frequency, and high- vs. low-perishability—when assessing the effectiveness of product advertisement locations in retailer direct mail flyers. Employing a quasi-experimental design, we analyze a national retail chain’s various featured produ...

Considerable research on merchandise returns has looked at marketing elements of the sales process (e.g., product display) and how they influence returns. However, marketing and order fulfillment processes are temporally decoupled in remote purchase situations such as online retail. While both are intricate parts of the overall sales transaction, i...

Purpose The purpose of this study is to investigate the relationship between social media and sensing capability for supply chain management (SCM) from an environmental scanning perspective. The authors consider upstream supply and downstream customer markets as two aspects of social media-enabled environmental scanning (SMES). The moderating effec...

Natural disasters are negative shocks that can severely disrupt the communities in which they occur. Disasters like hurricanes, tornados, floods, wildfires, and earthquakes, moreover, can cause severe property damage, including damages to homes, businesses, and automobiles. An important issue that arises is whether branches in communities affected...

While labor-displacing AI has the potential to transform critical aspects of society in the near future, previous work has ignored the possibility of the extreme labor displacement scenarios that could result. To explore this we surveyed attendees of three AI conferences in 2018 about near-to-mid-term AI labor displacement as well as five more extr...

Purpose There is a growing interest in the way non-profit organizations can use Twitter strategically to communicate their message, but little attention has been paid to the way content categories and features may facilitate retweets of messages of a non-profit organization that targets women as its audience. Based on stakeholder theory, this study...

The payday lending industry has been the subject of controversy over the years. This is largely due to the high fee structure of payday loans and the view of some that the industry targets economically vulnerable groups. For these reasons, some states prohibit payday lending, while others impose regulatory restrictions on their operations. Despite...

New product development (NPD) speed is an important concern for firms in today’s fast-paced economy. While existing literature has focused on continuous NPD speed improvements, this paper explores discontinuous NPD acceleration, or dramatic reductions in development time relative to firms’ normal NPD cycles. Across two studies, the authors intervie...

Exponentially weighted moving average (EWMA) control charts are typically used for faster detection of shifts in the process mean, relative to a Shewhart control chart, when the degree of shift is small. Normal guidelines suggest using a small (large) value of the weighting constant, λ, for detecting smaller (larger) shifts in the process mean. Pri...

Supply chain managers have yet to solve the conundrum of profitably distributing and selling to the poorest consumers. Most prevailing methods of addressing this problem take one of two contrasting approaches—that is, (1) price subsidization or (2) benefits/cash transfers. The former has been heavily studied in the literature with the consensus bei...

Transformative AI technologies have the potential to reshape critical aspects of society in the near future. However, in order to properly prepare policy initiatives for the arrival of such technologies accurate forecasts and timelines are necessary. A survey was administered to attendees of three AI conferences during the summer of 2018 (ICML, IJC...

This article proposes and tests a dual-process model of corporate social responsibility (CSR) communication. Building on the framing theory and associative network theory, the authors examine how including statements about a company’s CSR fit and CSR history in apology statements can affect purchase intention and negative word of mouth (NWOM). Perc...

The purpose of this paper is to focus on the losses of two very big banks, Citigroup (Citi) and Wells Fargo & Company (Wells Fargo), and two very small banks, First Busey Corporation (Busey) and Capital City Bank Group (Capital), over the period 1991–2016. The federal government actually bailed out the two big banks, as measured by total assets, wh...

This article examines how gender influences top managers’ networking activities and what situational factors intensify or ameliorate such gender effects. Focusing on female top managers’ efforts to engage in external networking activities, the authors conceptualize how and why female managers might develop different networking patterns and how such...

Purpose: The global business environment combined with increasing societal expectations of sustainable business practices challenges firms with a host of emerging risk factors. As such, firms seek to increase supply chain transparency, enabling them to monitor operational activities and manage supply chain risks. Drawing on organizational informat...

Given the financial troubles facing state pension plans in recent years, we examine determinants of the ratio of assets to liabilities, or the funded ratio, based on data for 153 pension plans from 2001 to 2014. The focus is on the relationship between both the actual investment return on pension assets and the assumed return used to discount pensi...

Merchandise return policies (MRPs) have long been an important area of interest for operations and supply chain management researchers, who have identified some key advantages and disadvantages of offering comprehensive and convenient return policies. However, there is a lack of rigorous scholarship on one key dimension of MRPs-return time leniency...

Microeconomic theories, including diminishing marginal utility and opportunity cost, suggest that low-income consumers should have greater utility and lower opportunity costs associated with coupon redemption. Therefore, low-income households should redeem coupons more often than higher income households. Additionally, household composition should...

Organizational image, identity, and identification are powerful concepts in terms of understanding members’ behaviors and beliefs. In particular, the term “image” has frequently been used to describe the overall impression of the organization, but most scholars have only focused on organizational image as it is perceived by external audiences. Howe...

In the complex setting of intergovernmental relationships, explaining how and why organizations are involved in network relationships has been a central and enduring quest of scholars in public management. In the setting of public organizations, a considerable amount of research has been conducted on managerial networking and its effects on public...
