We examine whether cobrandingthe practice of using two established brand names on the same productincreases the market value of parent firms. Using data from the consumer packaged goods industry, we document that the average stock market reaction to the announcement of cobranded new products is approximately+ 1.0%. We hypothesize that this reaction is significantly higher than it would have been if these same products were single branded, and we find evidence consistent with this hypothesis. We also examine … [Full Text]

In recent years many algorithms have been proposed in the literature for solving the Max-Cut problem. In this paper we report on the application of a new Tabu Search algorithm to large scale Max-cut test problems. Our method provides best known solutions for many well-known test problems of size up to 10,000 variables, although it is designed for the general unconstrained quadratic binary program (UBQP), and is not specialized in any way for the Max-Cut problem.

In this article, we explore the differential effects of a firm’s reputation and status on its interorganizational network. We hypothesize that due to its stable, unitary, and relational characteristics, status has a stronger influence on partner selection than reputation, which is less stable, multidimensional, and based more on perceptions of product quality and financial performance. Results from our analyses of the director networks of the 300 largest US firms from 1985 to 1993 confirm that across multiple measures of network characteristics, it is status that is the stronger predictor. In particular, high-status firms have networks that are higher in partner quality but are less diverse and contain fewer opportunities to bridge structural holes than the networks of high-reputation firms. These results contribute to our understanding of the different effects of reputation and status on firm behavior by emphasizing the importance of studying both together in order to understand the effects of either. They also contribute to work on interorganizational networks by demonstrating how structure emerges primarily as a function of focal firm status.

Departing from the static perspective of leader charisma that prevails in the literature, we propose a dynamic perspective of charismatic leadership in which group perceptions of leader charisma influence and are influenced by group mood. Based on a longitudinal experimental study conducted for 3weeks involving 116 intact, self-managing student groups, we found that T1 group perceptions of leader charisma mediate the effect of leader trait expressivity on T2 positive and negative group moods. T2 positive and negative group moods influence T3 distal charisma perceptions by affecting T2 proximal perceptions of leader effectiveness. The current findings offer critical insights into (a) the reciprocal relationship between group perceptions of leader charisma and group mood, (b) the dynamic and transient nature of group perceptions of leader charisma, (c) the importance of understanding negative mood in charismatic leadership, and (d) the mechanism through which charismatic leadership perceptions can be formed and sustained over time.

Hundreds of studies have attempted to define, measure, or otherwise explain how website visitors think, feel, and behave during and after visits to transaction-oriented business-to-consumer retail websites. This article reviews the predominant endpoints described in the peer-reviewed literature over the past decade for user-website interactions with e-tail websites. Results suggest that although scores of user-website interaction outcomes have been reported in the peer-reviewed literature, most of those endpoints represent one of ten high-level user-website interaction outcomes (confirmation/disconfirmation, trust, perceived risk, engagement, purchase intentions, actual purchase behavior, satisfaction, repeat website visit intention or behavior, repeat purchase intention or behavior) either directly or indirectly. This article provides a new information technology systems-based taxonomy for relevant outcomes to define website outcomes, identifies their common characteristics, and summarizes the relationships so far reported in the peer-reviewed literature.

Current understanding of women entrepreneurs, and in particular those within emerging economies, remains limited. This is despite the fact that the prevalence of women entrepreneurs across emerging economies has grown. Consequently, using India as a research context, the purpose of this study was to identify specific human and social capital factors that may contribute to venture growth for women entrepreneurs in emerging economies. Results suggest that both human and social capital factors play a role in determining business growth for Indian women entrepreneurs. Specifically, human capital factors related to industry experience as well as prior entrepreneurial experience were significant contributors, as were social capital factors related to the size of individuals’ business networks and the support received from family members. However, education, parental business ownership, and network composition characteristics relative to kinship ties were not significant predictors of venture growth in an Indian context. [Full Text]

Brands have evolved into complex symbols which are difficult to manage. Personify the brand reconciles brand’s abstract meanings with practitioner’s pragmatism. That is, conceptualizing brands as if they were people, attributing human qualities to them. This approach not only allows the development of more competitive brands.

We uncover a strong comovement of the stock market risk–return trade-off with the consumption–wealth ratio (CAY). The finding reflects time-varying investment opportunities rather than countercyclical aggregate relative risk aversion. Specifically, the partial risk–return trade-off is positive and constant when we control for CAY as a proxy for investment opportunities. Moreover, conditional market variance scaled by CAY is negatively priced in the cross-section of stock returns. Our results are consistent with a limited stock market participation model, in which shareholders require an illiquidity premium that increases with CAY, in addition to the risk premium that is proportional to conditional market variance.

Both professionals and academics have long criticized the use of traditional financial performance measures and called for balance in performance measurement systems. In 1992, Kaplan and Norton introduced the Balanced Scorecard and it has been adopted widely around the world and offered as a superior combination of nonfinancial and financial measures of performance. This paper is the result of a 15-year field study of a Fortune 500 company’s Balanced Scorecard. Both qualitative and quantitative data were collected to address the following research questions with respect to the Balanced Scorecard: 1) What has changed over time? 2) What has not changed over time? 3) Why has it endured? Changes highlighted are that the Balanced Scorecard was unaffected by a major change in organizational structure, a narrowing of focus and reduction in the scope over time, processes for changing the design were formalized, and that it has become engrained in the compensation system. Factors that have remained constant over time are the purpose of the Balanced Scorecard, its use for relative performance evaluation, and its use as a tool for best practice sharing. Two factors that appear to explain why it has endured are its use as a learning and communication tool and its ability to influence behavior. The paper concludes with a list of key success factors for building and sustaining a successful scorecard. This list might also be helpful to researchers seeking to investigate the design, use or impact of a Balanced Scorecard.

Social media services and consumer computing devices are rapidly changing the way we are creating, distributing, and sharing emergency information during social crises (Palen et al. 2010; Palen et al. 2009; Shklovski et al. 2010; Shklovski et al. 2008; Starbird and Palen 2010). During large-scale crises (eg, natural disasters and terrorist attacks), it has become the norm that the incident is initially reported by a local eyewitness with a mobile communication device, the report is rapidly distributed through social media services, and … [Full Text]

Social network sites (SNSs) have attracted millions of users who interact with each other and with companies. However, few studies have examined the impact of knowledge sharing through electronic word of mouth (eWOM) in the context of SNSs. This paper investigates the relationship among the use of SNSs, users’ social capital, knowledge sharing, and eWOM. The results show that the intensity of use of SNSs is positively related to trust and identification which have a positive effect on eWOM quality. In addition, eWOM quality has a positive effect on knowledge sharing. Female users feel more strongly about eWOM quality when they trust others, or when they perceive that they belong to their SNS community when they use their SNS. Furthermore, female users feel more strongly about knowledge sharing when they perceive that eWOM quality is good. This study provides the theoretical framework of the relationship between eWOM and knowledge sharing on SNSs from the perspective of social capital. Practitioners could use this study as a rationale to utilize SNSs internally for organizational use, and externally for marketing purposes.

International Human Resource Management (IHRM) has become an important field of research. The first textbook on International Human Resource Management is approaching its 25th birthday (Dowling & Schuler, 1990; Dowling, Festing, & Engle,
2013) and the first journal dedicated to the investigation of human resource management topics in an international context established in 1989, the International Journal of Human Resource Management, is also close to it 25th Volume. Another specialized journal dedicated to international staff mobility, the Journal of Global Mobility, has been established by a group of prominent IHRM researchers this year. A regular conference dedicated to IHRM was established in the late 1980s and for more than 20 years this conference has convened biennially. It still enjoys strong support and the 13th Conference will be organized in Cracow, Poland in 2014.

In this paper, the cardinality constrained quadratic model for binary quadratic programming is used to model and solve the graph bisection problem as well as its generalization in the form of the task allocation problem with two processors (2-TAP). Balanced graph bisection is an NP-complete problem which partitions a set of nodes in the graph G = (N, E) into two sets with equal cardinality such that a minimal sum of edge weights exists between the nodes in the two separate sets. 2-TAP is graph bisection with the addition of node preference costs in the objective function. We transform the general linear k-TAP model to the cardinality constrained quadratic binary model so that it may be efficiently solved using tabu search with strategic oscillation. On a set of benchmark graph bisections, we improve the best known solution for several problems. Comparison results with the state-of-the-art graph partitioning program METIS, as well as Cplex and Gurobi are presented on a set of randomly generated graphs. This approach is shown to also work well with 2-TAP, comparing favorably to Cplex and Gurobi, providing better solutions in a much shorter time.

This paper examines whether political activism increases people’s propensity to participate in the stock market. Our key conjecture is that politically active people follow political news more actively, which increases their chance of being exposed to financial news. Consequently, their information gathering costs are likely to be lower and the propensity to participate in the market would be higher. We find support for this hypothesis using multiple micro-level data sets, state-level data from the US, and cross-country data from Europe. Irrespective of their political affiliation, politically active individuals are 9–25% more likely to participate in the stock market. Using residence in “battleground” states and several other geographic instruments, we demonstrate that greater political activism reduces information gathering costs and causes higher market participation rates. Further, consistent with our conjecture, we find that politically active individuals spend about 30 minutes more on news daily and appear more knowledgeable about the economy and the markets.
The relationship between macroeconomic developments and bank capital buffer and portfolio risk adjustments is relevant to assess the efficacy of newly created countercyclical buffer requirements. Using the US bank holding company data over the period 1992: Q1-2011: Q3, we find a negative relationship between the business cycle and capital buffer. Our results offer some support for the Basel III agreements that countercyclical capital buffer in the banking sector is necessary to help the performance of the real economy during … [Full Text]

This study investigates the effects of Corporate Social Responsibility (or CSR) fulfillment on consumer loyalty in the service market environment by comparing them with the effects of marketing mix strategies. This study also examines two potential mediating factors (i.e., service quality and consumer trust) in understanding how CSR relates to consumer loyalty. The results show that CSR performance builds customer trust, which leads to customer loyalty. CSR activities also affect customer perceptions of service quality although their effect is weaker than that of marketing mix strategies. The paper concludes with a discussion of the implications of the study for researchers and marketers.

This study differs from previous studies on open source software (OSS) developer motivation by drawing upon theories of volunteerism and work motivation to investigate the motives and attitudes of OSS volunteer developers. The role of commitment is specifically interesting, which is well established in the volunteerism and work motivation literature as a predictor of turnover and positively related to work performance, but has been overlooked by OSS researchers. The authors have developed a research model relating …
