Inventory in Times of War

Abstract:

We study how armed conflicts affect inventory across firms’ production facilities. We track 38,916 production facilities—including plantations, livestock farms, and factories—in war-torn Colombian regions; we also collect the data of 5,138 attacks performed by the two rebel groups involved in Colombia’s civil war. To obtain exogenous variation in the conflict intensity, we use a difference-in-differences model that hinges on the peace process between the government and one of the guerrilla groups. We find that when the conflict intensity increases by one order of magnitude, inventory decreases by up to 10.38%. Firms, however, barely reduce finished inventory during war; they mainly reduce raw and work-in-process inventory. To offset this inventory reduction, firms increase their cash holdings—that is, they shift their working capital from physical inventory to liquid assets. The location of the facility moderates the effect of war: when a facility is close to a distribution center—hence, inventory travels short distances—the firm responds to violence by aggressively reducing inventory; when a facility is far from a distribution center, the firm reacts less aggressively to war.

Software Patents and Firm Value: A Real Options Perspective on the Role of Innovation Orientation and Environmental Uncertainty

Abstract:

Although software patents have been growing steadily since 1996, when the restrictions on the patentability of software were eliminated, their value and impacts on the firm’s profits remain unclear and ambiguous. Drawing on the real options theory and the literature on exploration and exploitation, we develop a novel theoretical framework to assess the value of software patents. Moreover, we examine the impact of contextual factors related to the nature of innovation underlying firms’ patent portfolios (exploitative versus explorative) and the environmental uncertainty (competitiveness and dynamism) on the value of software patents. Specifically, we examine the interaction effect of a firm’s software patent stock and its innovation orientation on firm value in markets exhibiting different levels of environmental uncertainty. Based on a large-panel data set consisting of 602 U.S. firms, our results indicate that a software patent portfolio having higher levels of explorative orientation is associated with a higher firm value (as measured by Tobin’s q) in environments exhibiting low dynamism and high competitiveness. By contrast, a software patent portfolio with higher levels of exploitative orientation is associated with a higher firm value in environments with high dynamism and low competitiveness. We discuss the implications for research and practice.

Financial Returns to Firms’ Communication Actions on Firm-Initiated Social Media: Evidence from Facebook Business Pages

Abstract:

The primary goal of this study is to investigate the financial returns to firms’ communication actions on a firm-initiated social media platform by focusing on Facebook Business pages. To this end, we conceptualize and quantify two types of firms’ communication actions on social media: posts and responses to customer messages. Furthermore, we classify a firm’s responses to customer messages based on the valence of customer messages—positive versus negative—and examine the effects of volume as well as timeliness of the two types of a firm’s responses to customer messages on firm performance. Using a sample of 63 South Korean firms across industries over a three-year period (5,566 firm-week observations), we find that the volume and timeliness of a firm’s responses to negative customer messages, which are associated with an increase in customer satisfaction, have a significant positive impact on the firm’s market performance measured by abnormal returns and Tobin’s q. Interestingly, the results suggest that a firm’s posts and its responses to positive customer messages are not significantly associated with firm performance. Furthermore, we find that a firm’s posts and its responses to negative customer messages exhibit complementarities in contributing to firm performance. Our results are robust to various alternative specifications, econometric concerns, and Facebook’s policy changes, such as EdgeRank and Promoted Post. Our findings underscore the business value of firms’ actions on social media and provide unique and important implications for theory and practice regarding the appropriate ways to use social media for building and managing customer relationships.

The Role of Decision Support Systems in Attenuating Racial Biases in Healthcare Delivery

Abstract:

Although significant research has examined how technology can intensify racial and other outgroup biases, limited work has investigated the role information systems can play in abating them. Racial biases are particularly worrisome in healthcare, where underrepresented minorities suffer disparities in access to care, quality of care, and clinical outcomes. In this paper, we examine the role clinical decision support systems (CDSS) play in attenuating systematic biases among black patients, relative to white patients, in rates of amputation and revascularization stemming from diabetes mellitus. Using a panel of inpatient data and a difference-in-difference approach, results suggest that CDSS adoption significantly shrinks disparities in amputation rates across white and black patients—with no evidence that this change is simply delaying eventual amputations. Results suggest that this effect is driven by changes in treatment care protocols that match patients to appropriate specialists, rather than altering within physician decision making. These findings highlight the role information systems and digitized patient care can play in promoting unbiased decision making by structuring and standardizing care procedures.
