A Call for Authenticity: Audience Responses to Social Media Influencer Endorsements in Strategic Communication

ABSTRACT

Utilizing social media celebrities as a communication channel has become a strategic practice for many organizations. By using the concepts of celebrity endorsement and authenticity, the effect of celebrity and content characteristics on followers’ attitudes towards the content and, in the case of sponsored content, purchase intentions are scrutinized. Instagram followers (N = 592) of 45 celebrities responded to a survey on nine photos of the celebrities. The results show that both the perceived authenticity and attractiveness of the celebrity are positively related with photo attitudes, but only authenticity has an effect on purchase intentions. Photos of social media influencers, people who have become famous through social media, increase purchase intentions more than photos of general celebrities. Congruence between the photo and the celebrity has the strongest positive effect on photo attitudes and purchase intentions. Sponsored photos are less favorably perceived than non-sponsored photos, but, among sponsored photos, sponsor disclosure has no effect on purchase intentions. The perceived authenticity of both the celebrity and her content is said to explain favorable audience perceptions. The findings imply that organizations should seek authentic matches between their message and the endorsing celebrity and that the content should align with the usual style of the celebrity.     

Institutional duality and human resource management practice in foreign subsidiaries of multinationals

We examine how institutional context affects the decisions that subsidiaries of multinational corporations (MNCs) make in pursuing particular human resource management (HRM) practices in response to institutional duality. Drawing on Varieties of Capitalism, along with the concept of intermediate conformity, we argue that the use of particular HRM practices by MNC subsidiaries will differ depending on both the combination of home and host institutional contexts, and on the nature of the particular practice under consideration. Using data from a survey of HRM practices in 1196 firms across 10 countries, we compare HRM practices in subsidiaries located and headquartered in different combinations of liberal and/or coordinated market economies. Our study suggests MNC subsidiaries conform only to the most persuasive norms, while exercising their agency to take advantage of the opportunities presented by institutional duality to adopt practices that distinguish them from indigenous competitors.     

Still feeling employable with growing age? Exploring the moderating effects of developmental HR practices and country-level unemployment rates in the age – employability relationship

Abstract

A compelling issue for organizations and societies at large is to ensure external employability of the workforce across workers’ entire work-life span. Using the frameworks of age norms, stereotyping and age meta-stereotypes, we investigate whether (a) age is negatively related to perceived external employability; and (b) the age-employability link is moderated by HR developmental practices (HRDPs) and unemployment rate. We argue that being aware of stereotypes and age norms in organizations, and holding also meta-stereotypes about their group, older workers perceive themselves as less externally employable. However, the context –HRDPs that one has experienced, and the country unemployment rate – would act as buffers. Using data from a large-scale survey from over 9000 individuals in 30 institutionally diverse countries, we found that the negative relationship between age and perceived external employability was significant across all countries. In addition, at the individual level, we found that HRDPs acted as a buffer for this negative relationship, such that the effect was less pronounced for individuals who have experienced more HRDPs during their working life. At the country level, the hypothesized moderating effect of unemployment rate was not observed. Limitations, future research directions, as well as practical implications of the study are discussed.     

The Shifting Geopolitics of Water in the Anthropocene

This forum responds to recent calls to hypothesize a geopolitics of the Anthropocene by examining how our notions of geopolitics of water may shift in the context of this new and, at times, divisive framework. The Anthropocene describes the geological epoch in which humans are the dominant actor in the global environmental system and has been a concept that is not without controversy. Taking the Anthropocene as an epistemological divergence where nature can no longer be viewed as separate from humanity, this forum asks how moving away from understanding hydraulic systems as essentially stable to understanding them as unstable and profoundly influenced by humans changes our understanding ofthe geopolitics of water. Collectively the contributions to this forum illustrate that formulating a water geopolitics of the Anthropocene requires 1) moving beyond a focus on fluvial flows to consider other forms of water; 2) broadening our understanding of the actors involved in water geopolitics; 3) examining new geopolitical tactics, particularly those grounded in law; 4) engaging critically with new and emerging forms of visualization and representation in the geopolitics of water, and; 5) examining how the notion of the Anthropocene has been used towards geopolitical ends and worked to elide different positionalities.     

Improved instrumental variables estimation of simultaneous equations under conditionally heteroskedastic disturbances

In this paper we develop estimation techniques and a specification test for the validity of instrumental variables allowing for conditionally heteroskedastic disturbances. We propose modified two‐stage least squares (2SLS) and modified 3SLS procedures where the conditional heteroskedasticity is taken into account, which are natural extensions of the traditional 2SLS and 3SLS estimators and which achieve a lower variance. We recommend the use of these modified 2SLS and 3SLS procedures in practice instead of alternative estimators like limited‐information maximum likelihood/full‐information maximum likelihood, where the non‐existence of moments leads to extreme values, and also for ease of computation. It is shown theoretically and with simulation that in some cases 2SLS, 3SLS and our modified 2SLS and 3SLS procedures can have very severe biases (including the weak instruments case), and we present bias correction procedures to apply in practice along the lines of Flores‐Lagunes ( 2007 ). Our new estimation procedures can also be used to extend the test for weak instruments of Stock and Yogo ( 2005 ) and to allow for conditional heteroskedasticity. Finally, we show the usefulness of our estimation procedures with an application to the demand and supply of fish. Copyright © 2010 John Wiley & Sons, Ltd.     

Managing unintentional dwelling fire risk

In this paper, we examine the management of unintentional dwelling fire risk through the development of a geographical information system (GIS) for dwelling fire prevention support based upon an 18-month case study in a UK fire and rescue service. Previous research into causal factors in unintentional dwelling fire incidents was used to guide the development of a multiple linear regression risk model for dwelling fire incidents that was the basis of the GIS developed. The GIS provided a more detailed analysis of unintentional dwelling fire risk factors, and enabled more targeted fire prevention activities for the identified at-risk social groups.     

Options as a predictor of common stock price changes

Since rather novel techniques such as neural nets allow investigation of nonlinear model specification previously untested, it may be that traditional models of price formation underperform through misspecification rather than market efficiency. This paper explores whether a multilayer backpropagation model offers exploitable profit opportunities for some limited period. Using an intradaytransaction dataset obtained from the European Options Exchange (Amsterdam), We attempted to predict the return on Philips. Two neural nets are contrasted to ordinary linear regression analysis on the basis of three benchmarks (MSE, and net realized returns). An adaptively trained 33-14-1 architecture scored best on all criteria and yielded an annualized 11% return following a simple one-period trading strategy.     

A framework for analyzing intergovernmental collaboration – The case of ASEAN tourism

Intergovernmental collaboration in tourism among ASEAN nations has received little attention in the literature despite the significant economic contribution that tourism makes in the region. This paper helps to improve our understanding of the phenomenon by providing an overview of the progress made since 2002, and exploring the factors that facilitated and hindered progress. It was found that many of the suggested measures in the action plan, 'Roadmap for Integration of Tourism Sector’, were either not implemented at all or are overdue, although relatively significant progress was made in travel facilitation and human resources development. The authors suggest that current theories of collaboration do not adequately explain the patterns of ASEAN tourism. The paper seeks to expand the boundaries of theory by presenting a framework of collaboration which dissects the facilitators and inhibitors along three dimensions: stakeholders, resources, and processes and mechanisms. Recommendations to expedite and strengthen the collaboration are then formulated.     

Accruals quality and the incentive contracting role of earnings

This paper investigates the association between accruals quality and the usefulness of accounting earnings in incentive contracting. Accruals quality, which measures the precision with which accruals predict future cash flows, has two potential opposing effects on the noise in earnings as a measure of managerial performance. Specifically, higher quality accruals should decrease the deviations of earnings from future cash flows and increase the sensitivity of earnings to cash flows that are not attributable to managerial actions. My evidence indicates that better accruals quality is associated with a higher weight on earnings in compensation contracts, which suggests that accruals quality overall reduces the noise in earnings. I also find that the positive association between accruals quality and the weight on earnings is mainly driven by innate accruals quality rather than discretionary accruals quality. Therefore, accrual errors resulting from the volatility of the operating environment are a primary source of noise in earnings considered by compensation committees.
