We examine when anomaly returns occur. We use a powerful database that contains the precise date on which accounting information is first made public. Despite recent findings to the contrary, once timing is considered, anomalies exist in the data.
Using a novel database on venue short sales and market design characteristics, we ask: Where do short sellers exploit their information advantage?
Empirical research in operations management has increased steadily over the last 20 years. In this paper, we discuss why this is good for our field and offer some comments on the qualities we admire in an empirical operations management paper.
We study differences in the effects of prices, non-price promotions, and brand line length on brand shares at different retail formats. Our conceptual framework rests on the presence of trip level fixed and category level variable utility components and shows how the trade-off between these components results in (i) different formats visited on different types of shopping trips; and (ii) differential marginal sensitivities of brand shares to changes in marketing mix variables across trip types.
Community banks are the central financial institution in many places. They have the capacity to alleviate credit constraints of small firms. This may increase economic resilience, delaying or mitigating the effects of the Great Recession. We estimate how the county-level banking access and community bank market share affect both the timing and duration of the Great Recession. Using the Cox Proportional Hazards Model, we find that communities with a higher community bank market share are either less likely to experience recession conditions, or experience these conditions later. Using the Heckman Selection model, we confirm these results, and show that communities with a higher community bank market share are less likely to experience recession conditions. This research provides the first link between local financial institutions, and economic resilience.
In this paper, we empirically analyze the determinants of excess inventory announcement and the stock market reaction to the announcement in the US retail sector. We examine if the firm’s operational competence, as measured by total factor productivity (TFP), can explain the retailer’s excess inventory announcement. We also investigate if the stock market reaction to such announcements is conditional on the operational competence of the announcing firm. We use a combined dataset on excess inventory announcements, annual financial statements, and daily stock prices of publicly traded retailers in the USA between 1990 and 2011.
Abstract Supply chains are often characterized by the presence of a dominant buyer purchasing from a supplier with limited capacity. We study such a situation where a single supplier...
When financially distressed firms have overwhelming debts, a prominent option for survival is to file for Chapter 11 bankruptcy protection. We empirically study the effect of Chrysler’s Chapter 11 bankruptcy filing on the quantity sold by its competitors in the U.S. auto industry.
Networks of serial entrepreneurs, investors, and their affiliated companies play a critical role in driving entrepreneurial behavior, investor focus, and innovation hot spots within specific industry sectors and are critical for shaping the character of robust regional economies.
Many of the most prosperous places in the U.S. are hotbeds of technology and also the home bases of companies which exercise monopoly power across much larger territories – nationally, or even globally. This paper makes four arguments about regional income disparities.
The essence of a brand is that it delivers on its promises. However, consumers’ trust in brands (CTB) has declined around the world in recent decades. As a result, CTB has become a major concern for managers. The authors examine whether CTB is influenced by marketing-mix activities (i.e., advertising, new product introduction, distribution, price, and price promotion) implemented by brands.
We investigate how auditor alignment, i.e. parent and subsidiary are audited by auditors from the same audit firm network, affects the quality of the internal information environment of groups and their subsidiaries decision making and performance management processes. We predict that auditor alignment improves internal information quality via better information coordination across the group, and via lower internal information asymmetry between parent and subsidiaries.
This monograph provides a structured overview of costing system research that can explain the variation in the characteristics and properties of costing systems found in practice based on firms’ source(s) of their demand for cost information. Costing systems are not developed in a vacuum but are designed to fulfill a purpose. In order to have a meaningful decision on the various demands for cost information, I start in Part 1 by exploring the different techniques firms can use to supply cost information to its managers and employees.
This study finds that greater asymmetric timeliness of earnings in reflecting good and bad news is associated with slower resolution of investor disagreement and uncertainty at earnings announcements. These findings indicate that a potential cost of asymmetric timeliness is added complexity from requiring investors to disaggregate earnings into good and bad news components to assess the implications of the earnings announcement for their investment decisions.
In the last few decades, many healthcare institutions converted their ownership type from nonprofit to for-profit, contributing to an increased presence of for-profit ownership in the U.S. healthcare sector. There have been opposing views on whether such ownership conversions benefit the public. Employing a large panel dataset of U.S. nursing homes from 2006 to 2015, we conduct a difference-in-differences analysis on converted facilities’ financial performance, operating policies, and quality of care. We observe that converted facilities significantly increased their post-conversion profit margins, compared to propensity-score-matched controls.
Customer care employees (CCEs) are an excellent source of ideas for new and enhanced services for customers. By serving many customers, CCEs have the ability to see patterns in unserved and underserved needs. By being inside rather than external to the firm, CCEs have the ability to offer suggestions that build on existing capabilities, which result in ideas that are more easily implementable. There is a long history of research and practice for soliciting suggestions from employees, but little of this work has described how CCEs can be organized into a temporary online crowd to cocreate innovative ideas.
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).
The effectiveness of cancer screening and adherence to cancer screening guidelines can be inhibited by long wait times for screening appointments. We develop a queueing network model of screening for a disease within a population of patients with imperfect adherence to screening guidelines to characterize the relationship between the screening request frequency rate and the wait time for screens. We first use our model to derive the capacity needed by a given system or the population size a given system can serve to guarantee a certain service level.
Despite recognizing the importance of events, researchers have rarely explored the influence of broader societal events on employee experiences and behaviors at work. We integrate perspectives on events and social identities to develop a cross-level theoretical model of the spillover effects of mega-threats, which we define as negative, large-scale, diversity-related episodes that receive significant media attention.
Scholars have long been interested in new industry emergence, highlighting that it could often be impeded by uncertainty across four dimensions: technology, demand, ecosystem, and institutions. Building on the insight that uncertainty stems from partial knowledge, we develop a conceptual framework that utilizes a temporal and a process perspective for knowledge generation and aggregation.
