Publication: Meta-Analyses as a Multilevel ModelGooty, J., Banks, G.C., Loignon, A.C., Tonidandel, S., & Williams, C. E.

Published in: Organizational Research MethodsJuly 24, 2019,  https://doi.org/10.1177/1094428119857471

Abstract: Meta-analyses are well known and widely implemented in almost every domain of research in management as well as the social, medical, and behavioral sciences. While this technique is useful for determining validity coefficients (i.e., effect sizes), meta-analyses are predicated on the assumption of independence of primary effect sizes, which might be routinely violated in the organizational sciences. Here, we discuss the implications of violating the independence assumption and demonstrate how meta-analysis could be cast as a multilevel, variance known (Vknown) model to account for such dependency in primary studies’ effect sizes. We illustrate such techniques for meta-analytic data via the HLM 7.0 software as it remains the most widely used multilevel analyses software in management. In so doing, we draw on examples in educational psychology (where such techniques were first developed), organizational sciences, and a Monte Carlo simulation (Appendix). We conclude with a discussion of implications, caveats, and future extensions. Our Appendix details features of a newly developed application that is free (based on R), user-friendly, and provides an alternative to the HLM program.

Publication: The effect of traditionally marginalized groups in advertising on consumer response; Enrica N. Ruggs, Jennifer Ames Stuart, Linyun W. Yang.

Published in: Marketing LettersSeptember 2018, Volume 29, Issue 3pp 319–335.

Abstract: Increasingly, national brands have cast people from marginalized groups in advertising. It is important to understand the elements that influence consumers’ responses to advertisements featuring groups who have been traditionally excluded from advertising campaigns. Although consumers may wish to buy brands that support their own views on human rights and equality, we propose that consumers in the target market may be uncomfortable if the group portrayal contradicts their beliefs about the topic, concept, or social groups in the ad. Across two studies, we show that when an ad creates this type of internal contradiction within consumers, it may elicit a more negative response than an ad portraying a more traditional model. However, we also find preliminary evidence that using models from marginalized groups can be more effective than using more traditional models—as long as such portrayals do not violate certain target consumers’ schemas. The implications of these results will be discussed.

Publication: Market Evidence against Widespread Point Shaving in College Basketball; Jason Berkowitz, Craig Depken, and John Gandar.

Published in: Journal of Economic Behavior & Organizationvolume 153, pp. 283-292.

Abstract:  This paper proposes using market-based information to investigate the likelihood of widespread point shaving in college basketball games with strong favorites. Information embodied in pre-game money lines facilitates the calculation of the market’s expectation that the game will end with a strong favorite winning but not covering the point spread, a result deemed suspicious in previous studies. Additional market-based information embodied in second-half lines reveal how the market’s expectation about second-half play differs from pre-game expectations. Applying our methodology to college basketball reduces previous estimates of the percentage of games thought to be consistent with potential point shaving to insignificant levels. Our approach can apply to other sports in which strong favorites are common.

Publication: Much Ado about Nothing: The (Lack of) Economic Impact of Data Privacy Breaches; Vernon Richardson, Marcia Weidenmier Watson and Rodney E. Smith.

Published in: Journal of Information SystemsIn press.

Abstract:  In this paper, the authors examine the consequences of data breaches using a long event window and a sample many times larger than most extant research.  They find the economic consequences are, on average, very small for breached companies.  On average, breaches result in less than -0.3% cumulative abnormal returns in the short window around the breach disclosure.  Except for a few catastrophic breaches, the nominal difference in cumulative abnormal returns between breach companies and the matched companies disappears within days after the breach.  The authors also test whether data breaches affect future accounting measures of performance, audit and other fees, and future Sarbanes Oxley Section 404 reports of material internal control weaknesses.  They find no differences between breach and matched companies.  The results answer the question why companies are not spending more to reduce breaches—because most companies do not experience a material economic impact from a breach.  Thus, the authors provide a few explanations of why there appears to be an effect at the economy-wide level, but no noticeable effect on individual company performance.

Publication: Geography Still Matters: Examine the Role of Location in Online Markets for Foreign Branded Products; Xia Zhao, Kexin Zhao and Jing Deng.

Published in: Decision Sciences, 05 Sept 2018

Abstract: Internet technologies and e‐commerce have significantly reduced communication and search costs and facilitated trade between distant parties. It has been advocated that the world becomes flat and geographic divisions are gradually irrelevant. However, recent studies have identified a type of location advantage in online platforms, that is, home bias. To further explore the role of geography in online markets, this study investigates another type of location advantage, the country of origin (COO) effect for online sellers. Using a large listing and transaction data set collected from both an e‐commerce retail platform in China and the official Web sites of two foreign brands, we examine the impact of geographic location on online sellers’ pricing strategies and transaction quantities. Our research provides empirical evidence supporting the existence of the COO effect for online sellers in the context of foreign branded product exchanges. Furthermore, the results suggest that sellers’ location information can be a substitute to their reputation and observable effort in facilitating online transactions.

Published in: Journal of the Academy of Marketing Science, 46 (3), 384-402

Abstract: This research investigates how national culture interacts with marketing strategy to influence consumers’ organic post-consumption satisfaction ratings of entertainment products rich in cultural content. Drawing upon a communication theory framework, the authors develop hypotheses concerning multiple interaction effects between culture and marketing strategies on consumers’ product evaluations. The authors test these hypotheses by analyzing consumer reviews of 260 movies in 25 country markets. In support of the hypotheses, the authors find that the cultural congruence between the product and the market improves consumer reviews, and that the effect is stronger in cultures characterized by collectivism, femininity, and uncertainty avoidance, as well as for products more heavily loaded with cultural content. In addition, the authors find that the negative effect of delay in product launch timing weakens for cultures characterized by long-term orientation, and that the positive effect of advertising spending on consumer evaluations is stronger in cultures characterized by high power distance belief. These results provide practical insights into how managers should make decisions concerning product design, launch timing, and advertising strategies in international markets.

Published in: Journal of Financial Economics, Volume 129, Issue 1, July 2018, Pages 111-135

Abstract: The authors construct a measure of the pairwise relatedness of firms’ human capital to examine whether human capital relatedness is a key factor in mergers and acquisitions. The authors find that mergers are more likely and merger returns and postmerger performance are higher when firms have related human capital. These relations are stronger or only present in acquisitions where the merging firms do not operate in the same industries or product markets. Reductions in employment and wages following mergers with high human capital relatedness suggest that the merged firm has greater ability to layoff low quality and/or duplicate employees and reduce labor costs. The authors further show in a falsification test that human capital relatedness has no effect on acquiring firm returns in asset sales when little or no labor is transferred, which helps validate our measure of human capital relatedness.

Publication: Social Class in the Organizational Sciences: A Conceptual Integration and Meta-Analytic ReviewAndrew C. Loignon and David J. Woehr

Published in: Journal of Management, Volume 44, Issue 1, January 2018, pp. 61–88

Abstract: Social class has become increasingly popular in the organizational sciences. Despite the burgeoning interest in this topic, there remains a great deal of ambiguity concerning the conceptualization and operationalization of social class. For instance, scholars have used income, education, and subjective ratings to measures one’s social class. In order to improve the conceptual clarity of social class, we develop and present a model that draws on the dominant theories of social class from both sociology and psychology while organizing their key principles to explain how social class influences an individual’s thoughts, feelings, and behaviors. By using this model as a framework, this study attempts to refine the conceptualization of social class by testing core research questions pertaining to the construct validity of this construct. After a comprehensive, interdisciplinary literature search, which yielded over 4,000 effect sizes, we conducted a meta-analysis to test the proposed model. The findings offer clear support for two distinct components of social class (i.e., objective and subjective) that are both highly related to one another and associated with other microlevel constructs (i.e., job attitudes). Given the timeliness and importance of social class, the findings of this conceptual review and empirical meta-analysis offer a means of summarizing this large, interdisciplinary literature while guiding future management research on this critical topic.

Publication: A picture is worth a thousand words: Translating product reviews into a product positioning map, Sangkil Moon and Wagner A. Kamakura

Published in: International Journal of Research in Marketing, 2017, Vol.34 (1), p.265-285

Abstract: Product reviews are becoming ubiquitous on the Web, representing a rich source of consumer information on a wide range of product categories (e.g., wines and hotels). Importantly, a product review reflects not only the perception and preference for a product, but also the acuity, bias, and writing style of the reviewer. This reviewer aspect has been overlooked in past studies that have drawn inferences about brands from online product reviews. Our framework combines ontology learning-based text mining and psychometric techniques to translate online product reviews into a product positioning map, while accounting for the idiosyncratic responses and writing styles of individual reviewers or a manageable number of reviewer groups (i.e., meta-reviewers). Our empirical illustrations using wine and hotel reviews demonstrate that a product review reveals information about the reviewer (for the wine example with a small number of expert reviewers) or the meta-reviewer (for the hotel example with an enormous number of reviewers reduced to a manageable number of meta-reviewers), as well as about the product under review. From a managerial perspective, product managers can use our framework focusing on meta-reviewers (e.g., traveler types and hotel reservation websites in our hotel example) as a way to obtain insights into their consumer segmentation strategy.

Publication: Software Diversity for Improved Network Security: Optimal Distribution of Software-Based Shared Vulnerabilities, Orcun Temizkan, Sungjune Park, & Cem Saydam

Published in: Information Systems Research (December 2017)

Abstract: Firms, and other agencies, tend to adopt widely used software to gain economic benefits of scale, which can lead to a software monoculture. This can, in turn, involve the risk of correlated computer systems failure as all systems on the network are exposed to the same software-based vulnerabilities. Software diversity has been introduced as a strategy for disrupting such a monoculture and ultimately decreasing the risk of correlated failure. Nevertheless, common vulnerabilities can be shared by different software products. We thus expand software diversity research here and consider shared vulnerabilities between different software alternatives. We develop a combinatorial optimization model of software diversity on a network in an effort to identify the optimal software distribution that best improves network security. We also develop a simulation model of virus propagation based on the susceptible-infected-susceptible model. This model allows calculation of the epidemic threshold, a measure of network resilience to virus propagation. We then test the effectiveness of the proposed software diversity strategies against the spreading of viruses through a series of experiments.

Publication: Financial Reporting Quality and Auditor Locality Contagion, Jamie Diaz, Gregory W. Martin, & Wayne B. Thomas

Published in: Auditing: A Journal of Practice and Theory (November 2017)

Abstract: Research in information economics seeks to understand how the actions of one individual affect the decisions of related individuals. We examine this issue in the context of information contagion between audit offices in the same locality. Specifically, we investigate whether contagion among Big N audit offices in the same metropolitan statistical area (MSA) causes their client firms’ financial reporting quality to correlate. We document a relation between overstatement of earnings for one firm (as evidenced by a subsequent restatement) and higher abnormal accruals for another firm in that same year, where both firms’ auditors are located in the same MSA. The correlation in reporting quality is consistent with contagion in practices between auditors. We also find evidence that auditor competition is one channel through which information contagion occurs. The between-audit office contagion we document is incremental to within-audit office contagion documented by prior research. Our evidence is important in understanding additional factors related to the quality of auditing and financial reporting and thus should be relevant to audit committees, regulators attempting to improve audit quality, and stakeholders in general.

Published in: American Economic Journal: Applied Economics (2017)

Abstract: We study the short-run, causal effect of Information and Communication Technology (ICT) adoption on the employment and wage distribution. We exploit a natural experiment generated by a tax allowance on ICT investments and find that the primary effect of ICT is to complement non-routine, cognitive-intensive work. We also find that the ICT investments led to organizational changes that were associated with increased inequality within the firm and we discuss our findings in the context of theories of ICT adoption and wage inequality. We find that tasks-based models of technological change best fit the patterns that we observe.

Publication: Who Are Your Friends? The Influence of Identification and Family In- and Out-Group Friendships on Nonfamily Employee OCB and Deviance, Laura Marler & Laura Stanley

Published in: Entrepreneurship Theory and Practice (forthcoming)

Abstract: To better understand non-family employee OCB and deviance within family firms, we refine the conclusions that family friendships are beneficial (e.g., Vardaman et al. (forthcoming)) by offering a more nuanced perspective that not all friendships are created equal. Building on the work of Eddleston & Kidwell (2012), we consider whether family member friends belong to the family in-group or the out-group. We propose that only friendships with in-group family members will have a positive influence on nonfamily employees’ organizational identification, resulting in higher levels of OCB and lower levels of deviance. On the other hand, friendships with out-group family members will be associated with lower levels of nonfamily employee OCB and higher levels of deviance. Thus, our theorizing expands the nascent literature on nonfamily employees, offering a theoretical rationale for their complex behavior.

Publication: Callable Contingent Capital: Valuation and Default Risk, Weidong Tian

Published in: Management Science 

Abstract: This paper proposes the use of contingent capital with a call provision, in which the insurer has an option to redeem the contingent capital at any time. I characterize in detail a unique dynamic equilibrium of common stock, subordinated contingent capital, and a senior standard bond under a simple yet sufficient and necessary condition that can be implemented easily. I further show that the issuance of callable contingent capital does not affect the default risk of an outstanding senior standard bond. As a result, callable contingent capital provides an alternative design for contingent capital using a prudential capital structure for a bank that is “too big to fail.”

Published in: Journal of Financial and Quantitative Analysis, 50(6), 1269-1292. 

Abstract: This paper examines data from 45 world markets and shows that the previously documented relation between mean returns and idiosyncratic volatility arises because of biases in volatility estimates that we can attribute to the bid–ask bounce in trade prices. We show that no significant relation exists between mean returns and idiosyncratic volatility estimated from quote-midpoint returns. Further, there is no significant relation between mean returns and the portion of transaction-price-based idiosyncratic volatility that is orthogonal to bid–ask spreads. The pricing of idiosyncratic volatility is due to the negative pricing of the bid–ask spread.

Publication: The effect of a temporary product distribution channel on supply chain performance, Moutaz Khouja and Jing Zhou

Published in: Naval Research Logistics

Abstract: We focus on explaining the growth of e-commerce platforms such as Groupon and LivingSocial.  To do so, we analyze a supply chain of a manufacturer and two retailers, a permanent retailer who always stocks the manufacturer’s product and an intermittent deal-of-the day retailer who sells the manufacturer’s product online for a short time. We find that without a deal-of-the-day (DOTD) retailer, it is suboptimal for the manufacturer to offer a quantity discount while it is optimal for the retailer to offer periodic price discounts to consumers. With the addition of a DOTD retailer, it is likely to be optimal for the manufacturer to offer a quantity discount. We show that even without market expansion, i.e., no exclusive DOTD retailer consumers, opening the intermittent channel can leave the permanent retailer no worse-off while increasing the manufacturer’s profit. We identify the regular and discounted wholesale prices and the threshold quantity at which the manufacturer should give the discount. We also identify the optimal retail prices. We find that opening the intermittent channel increases the profit of the manufacturer, is likely to decrease the average retail price and to increase sales, and may increase the permanent retailer’s profit.

Abstract: While the information systems scholarly and practice literatures both stress the importance of senior executive engagement with IT management, the recommendations for doing so remain, at best, limited and general. Examining the influence of serious IT-related deficiencies on CEO/CFO turnover within the post-SOX financial reporting context, specific CEO/CFO IT management responsibilities are identified: CEOs are shown to be held accountable for global IT management responsibilities, and CFOs are shown to be held accountable for demand-side IT management responsibilities. Implications for information systems research, management research and information systems practice are provided.

Abstract: We know that healthier mothers tend to have healthier infants, but we do not know how much of that relationship reflects the intergenerational transmission of genetic attributes versus environmental influences. From a policy perspective, it is crucial to understand which environmental influences are important and whether investments in one generation affect outcomes for the next. Schulkind uses variation in the implementation of Title IX to measure the effects of increased athletic opportunities on the health of infants. Babies born to women with greater athletic opportunities as teenagers have babies that are healthier at birth. They are less likely to be born of low or very low birthweight and have higher Apgar scores.

Recent Publication: The Palette that Stands Out: Color Compositions of Curated Online Visual UGC with Higher Consumer Interaction, Nima Y. Jalali and
Purushottam Papatla

Published in: Quantitative Marketing and Economics

Abstract: Photos posted by consumers on social media, like Instagram, often include brands. Despite the substantial increase in such photos, there have been few investigations into how prospective consumers respond to this visual UGC. We begin to address this gap in this research by investigating the role of the color compositions of photos in consumer response. Consumer response is operationalized as the proportion of views by visitors that stimulate clicks to enlarge the photo when it’s curated on the included brand’s website. Composition is operationalized as the specific combination of levels of the photo’s color attributes: hue, chroma, and brightness. Our goal is to identify the color compositions of photos, ceteris paribus, which get more clicks when they are curated. Data for our investigation comes from clicks over a one-year period on photos posted on Instagram curated by fifteen brands in six product categories on their sites. We assume Beta distributed proportions and calibrate a Beta regression using MCMC methods for our investigation. We find that click-rates are higher for photos that include higher proportions of green and lower proportions of red and cyan. We also find that chroma of red and blue are higher in photos with higher click-rates. Findings from our research led the sponsoring firm to modify its proprietary curation algorithm for client brands. The firm informed us that, post-modification, there has been a substantial increase in click-rates of curated photos for brands in several categories.

Published in: Academy of Management Journal

Abstract: Despite multiple high-profile calls—across decades and from multiple stakeholders—to address the widening gap between science and practice, the relevance of research conducted in the management domain remains in question. To once again highlight this issue and, more importantly, identify solutions, we explore the grand challenge of the science-practice gap by applying stakeholder theory. Using a grounded theory approach, we conducted a series of interviews (n = 38) and a focus group with academics and practitioners (e.g., executives, entrepreneurs, government officials) in order to develop a set of theoretical models and propositions that extend stakeholder theory. We supplemented our inductive theory building approach with a survey of academics (n = 828) and practitioners (n = 939) and a qualitative content analysis to identify 22 grand challenges (i.e., eight shared, eight uniquely academic, and six uniquely practitioner). We discuss the theoretical and practical implications of our findings and illustrate multiple directions for future research to build permanent bonds—not just temporary links—between science and practice.

Published in: The Journal of Finance

Abstract: The authors introduce a novel approach to estimating latent oil risk factors and establish their significance in pricing nonoil securities. The model, which features four factors with simple economic interpretations, is estimated using both derivative prices and oil-related equity returns. The fit is excellent in and out of sample. The extracted oil factors carry significant risk premia, and are significantly related to macroeconomic variables as well as portfolio returns sorted on characteristics and industry. The average nonoil portfolio exhibits a sensitivity to the oil factors amounting to a sixth (in magnitude) of that of the oil industry itself.

Recent Publication: Online Price Dispersion Revisited: How Do Transaction Prices Differ from Listing Prices?, Kexin Zhao, Xia Zhao and Jing Deng.

Published in: Journal of Management Information Systems. Volume 32, Issue 1, 2015.

Abstract: Price dispersion of a homogeneous product reflects market efficiency and has significant implications on sellers’ pricing strategies. Two different perspectives, the supply and demand perspectives, can be adopted to examine this phenomenon. The former focuses on listing prices posted by sellers, and the latter uses transaction prices that consumers pay to obtain the product. However, no prior research has systematically compared both perspectives, and it is unclear whether different perspectives will generate different insights. Using a unique data set collected from an online market, we find that the dispersion of listing prices is three times higher than the dispersion of transaction prices. More interestingly, the drivers of price dispersion differ significantly between listing and transaction data. The dispersion of listing prices reflects sellers’ perception of market environment and their pricing strategies, and it may not fully capture consumer behavior manifested through the variation of transaction prices. Our study indicates that the difference in perspectives taken on the online prices yields different results as to their dispersion.
