Building on social movement theory, this study assesses the influence of social media activism on the stock market performance of targeted firms. We focus on information published on Twitter by two critical stakeholders: consumer associations and trade unions. To the extent that social media represent a valid medium to mobilize stakeholders' activism, protests on Twitter may damage firm reputation, leading to capital market reactions. Using a corpus of over 1.5 million tweets referring to Spanish listed banks, we study the impact of activism by looking at targeted firms' abnormal variations in price and trading volume. Our findings suggest that the Twitter activism of key stakeholders has a significant impact on investors' decisions. Further, our empirical analyses indicate that the mechanisms affecting investors' behavior differ depending on the characteristics of the stakeholder group. Hence, this study contributes to understanding how social movements influence corporate behavior via social media. Copyright © 2017 John Wiley & Sons, Ltd and ERP Environment  相似文献

Children do not choose what to eat based on health issues alone, and the high availability of non‐nutritious food in the environment can be a barrier to the consumption of healthy foods. Brazilian children are consuming processed, savoury, rich in fat, sodium and refined carbohydrates rather than more nutrient‐dense foods. Foods offered in public school meals and those sold in private school canteens in Brazil are subject to regulation, but not the snacks brought from home. This study identified the suggestions of public and private school students about the characteristics that a snack should present in order to be considered both healthy and palatable. A qualitative exploratory study using focus groups was conducted with 128 primary school students aged 7–10 years old. Interviews were transcribed and content analysis was conducted, generating three categories: (1) foods actually consumed during snack breaks; (2) examples of foods considered healthy and/or tasty for consumption during snack breaks; and (3) desired characteristics of a healthy and tasty snack. Foods of high energy density and low nutritional value were mentioned as the most consumed snacks, usually brought from home or purchased within/near the schools. Consumption of meals offered by the National School Meal Program was reported by only one‐third of the public school students. Fruits, natural juices and vegetables were considered healthy foods; sweet‐tasting preparations containing fruits were considered tasty; while fruits and natural fruit juices were considered both healthy and tasty. Sweet‐tasting preparations containing fruits were mentioned as examples of snacks with the desired healthy/tasty characteristics. The disparity between what was actually consumed and what was reported as ideal leads us to question the availability in retail stores of healthy yet palatable foods that meet this population's desires.  相似文献

This paper proposes a new theoretical framework for assessing the influence of risk in shaping the governance form in biopharmaceutical inter-firm relationships. In particular, we propose a multidimensional operationalization of relational and performance risk and, by following Transaction Cost Economics (TCE) and Real Options (RO) theory constructs, we hypothesize a relation between the aforementioned risk components and the choice of governance form. Specifically, following TCE reasoning, we hypothesize that a high level of relational risk leads towards more hierarchical governance forms, while, following RO theory, we hypothesize that a high level of performance risk leads toward market-oriented governance forms; finally, we hypothesize a moderating effect of each risk component on the other. We empirically test our framework through the analysis of 353 inter-firm relationships signed worldwide between pharmaceutical and biotech companies from 2007 to 2010. The results show substantive support for our theoretical framework. Furthermore, we find a significant moderating effect of the performance risk on the TCE relation between relational risk and governance forms.  相似文献

The paper examines some issues related to different styles of innovation in some advenced countries. The statistical work carried out is an attempt to answer the questerion: to what extent do countries' styles of innovation differ and how often do similarities arise? The issue of similarity/dissimilarity of countries' styles of innovation is investigated in the last 100 years for a group of selected countries. The evidence provided is based on a US patent database held at the University of Reading and countries' styles of innovation are measured with the use of the RTA index in four historical periods. The conclusions of the paper are consistent with the theory of national systems of innovation. Countries show very different styles of innovation and, what is more important, this difference is stable over time. However, a selected combination of similar countries occurs in every period, thus underlining the existence of regional groups. These regional groups are the only pairs of countries showing technological similarity historically.  相似文献

This investigation assessed Mexican-American and Anglo wives' perceptions of family decisionmaking roles for the purchase of eight different goods and services. This comparison was used to explore the impact ethnic subculture plays in consumer behavior. The findings indicate that ethnicity significantly affects wives' perceptions of family decisionmaking roles for expensive items, and that this is not just due to common associations with other variables. This is an under researched area in which cross-national differences and basic socioeconomic disparities are often inaccurately attributed to culture.  相似文献

Cointegration analysis suggests that the buffer stock precautionary model accounts for the optimal reserve demand in nine developing countries located in Asia and Latin America. The corresponding VECMs are further interpolated, using the permanent and transitory innovation decomposition procedure, in order to assess the relative impact of the time series on the convergence to equilibrium after a shock. Finally the (asymmetric) effect on the speed of convergence of positive/negative changes in signal variables—such as the excess reserves of the previous period, relative competitiveness and US monetary stance—is found to be significant, in line with mercantilistic and fear of floating motives for hoarding reserves.  相似文献

Drawing on faultlines and challenging the assumption that family board members form a homogenous subgroup, we hypothesize that the distinction between executive and non‐executive family board members can create faultlines that affect firm performance. We propose that the discrepancy between results and goals can activate and exacerbate faultlines. Using a sample of 421 family small and medium‐sized enterprises (SMEs), we find a U‐shaped relationship between the ratio of family executive board members and firm performance showing the consequences of relationship‐based and task‐related faultlines. Moreover, we find that the U‐shaped relationship occurs when firms perceive that they under‐achieve their objectives, whereas a reverse J‐shaped relationship appears when firms over‐achieve their objectives.  相似文献
