Electronic Word-of-Mouth in Social Networking Sites: A Cross-Cultural Study of the United States and China

ABSTRACT

Understanding electronic word-of-mouth (eWOM) in social networking sites (SNSs) is crucial as consumers have potential to reach global audiences quickly and easily. This article presents the first cross-cultural study on eWOM in SNSs by examining social relationship variables between the United States and China. Specifically, social capital, tie strength, trust, and interpersonal influence were examined as potential predictors of eWOM communication in the emerging online social channels. The results suggest that national culture plays a significant factor that affects consumers’ engagement in eWOM in SNSs in the two countries. Theoretical and managerial implications for global Internet marketers were presented and discussed.     

Why does MNE performance vary across countries?: An inquiry into the competitive value of MNE assets

Variations in MNEs’ competitive positions across countries are a prevalent phenomenon in the business landscape, but are not fully explained by MNE theory. Building on competition theories and applying them to the context of MNEs, we hypothesize that the value of MNEs’ assets varies in relation to competitors of different nationalities and geographic scope, as well as across locations. These predictions are tested on US legal-services MNEs in competition with US domestic firms and non-US MNEs in the US and abroad. We find support for the hypothesized variations, particularly with reference to competitors’ location and nationality. These variations suggest that the value of MNE assets is relative, and that their varying market positions across countries are an inherent feature of international competition, calling for corresponding positioning and strategies.     

Evolving research on expatriates: what is ‘known’ after four decades (1970–2012)

The purpose of this paper was to provide a comprehensive review of the evolving research on a still key challenge for human resource management (HRM) in the globalized business of today: the expatriates and their impact on business performance. Research of four decades was reviewed to show what was known and what was not yet known. A bibliometric analysis was conducted to build a conceptual map of the evolving research. Up to 438 papers published in 104 different journals by 233 authors were analyzed. Most of the literature studies and research does not show a systematic approach, so this review may be useful for scholars and practitioners in the field of HRM and International Business Management in order to advance into the next stage of development on how to deal with and take advantage of hiring expatriates. Even after more than four decades of intensive research, the literature on expatriation is still nascent and requires higher order content. New contexts and organizations should be included in the research agenda, while an effort must be made in systematic approaches and in building higher order content in the international HRM field.     

GMM estimation of a structural demand model for yogurt and the effects of the introduction of new brands

The demand structure for yogurt is assumed to be properly described by a one level nested logit model that is applied to aggregate market data. Given the presence of endogenous regressors, suitably lagged endogenous variables (Arellano and Bover in J Econom 68:29–51, 1995; Blundell and Bond in J Econom 87:115–143, 1998) are proposed as instrumental variables. The validity of this set of instruments is discussed and price elasticities and marginal costs are recovered from the demand estimates. Total welfare gains associated to the introduction of two new brands by the same manufacturer are finally computed. Prices and profits decreased and total welfare increased.     

The conservation against development paradigm in protected areas: Valuation of ecosystem services in the Doñana social-ecological system (southwestern Spain)

The ecosystems of the Doñana social-ecological system (southwestern Spain) provide numerous ecosystem services to society. We valued the most important ecosystem services through a market-based approach, revealed-preference and stated-preference methods to assess the conservation effectiveness of the Doñana Protected Area, with consideration of existing human activities in surrounding lands. We also analysed the spatial distribution of the ecosystem services beneficiaries and the scale of their related markets. We found a clear trade-off between the local and global market values of ecosystem services because landscape management outside of the Doñana Protected Area promotes the provision of ecosystem services associated with international markets. Our results suggest that a conservation against development model occurs in the Doñana social-ecological system, in which land use intensification takes place outside of the Protected Area borders as a result of promoting marketed ecosystem services, while biodiversity conservation is the main activity inside the Protected Area. We conclude that protected areas should be part of a larger-scale, adaptive landscape management strategy in which conservation planning should be the focal element in coordinating sectoral policies in the context of social-ecological systems.     

Are commercial bank lending propensities useful in understanding small firm finance?

We consider recent criticism by Berger et al. (J Bank Finance 31:11–33, 2007) of the use of commercial bank lending propensities (e.g., small business loans/total assets) as research tools. We use 2SLS cross sectional regressions with bank fixed effects to examine the relationship between small business lending and bank size. Our results indicate that the propensity to lend to small businesses declines as bank size increases, and the growth in small business lending does not keep pace with the growth in bank size. An increase in bank asset size from $1 billion to $100 billion reduces the ratio of small business loans to total loans and leases by 28 percentage points. Contrary to Berger and Black (2007) we find that most small business loans are made by small banks. For 1993 to 2006 as a whole, small banks (those under $1 billion) accounted for only 14.1% of total deposits and 9.7% of total banking assets, but they accounted for 28.4% of small business loans outstanding. This is consistent with the pattern shown by lending propensities. We conclude that these propensities remain very useful tools in research on small firm finance.
