Purpose – The purpose of this paper is to develop a model of brand authenticity and analyze the antecedents and effects of the construct. Although there is no doubt about the relevance of authenticity in personal relationships, published research has yet not thoroughly explored the concept’s meaning in reference to brands. Design/methodology/approach – Based on socio-psychological attribution theories and grounding on the identity-based brand management approach, a causal model of brand authenticity is developed. The hypothesized relationships are analyzed using the partial-least-squares approach. The primary data are based on an online survey conducted in Germany (n = 600). The respondents were asked about fast-food and beer brands. Findings – The data show that brand authenticity positively impacts on brand trust. Furthermore, the key antecedents in the model (consistency, continuity and individuality of a brand) drive the perception of brand authenticity as hypothesized. Research limitations/implications – The model should be tested in further product categories and moderators should be integrated. Originality/value – The findings suggest that authenticity is perceived when a brand is consistent, continuous and individual in its behavior. Nevertheless, the empirical results indicate that the factor individuality has the lowest influence on perceived brand authenticity. This is an interesting finding, as being “unique” is commonly regarded as an important success factor in branding. Although the study’s findings confirm its relevancy, they relativize its importance: being consistent, meaning that a brand fulfills its brand promise at every brand-touch point, and being continuous, meaning that the brand promise reflects the essential core of the brand, are of major importance. © Emerald Group Publishing Limited.

This article seeks to determine the mechanism(s) behind the convergence of domestic counterterrorism regulations that has been noted across many Organisation for Economic Co-operation and Development (OECD) countries. Four hypotheses are developed and tested through regression analyses. These hypotheses examine (1) U.S. influence, operationalized though a unique U.S. footprint indicator; (2) national characteristics; (3) the extent to which states' domestic structures match; and (4) international networks. We find little support that U.S. influence matters. The international influence that does exist seems to operate through networks promoting learning, especially following a rise in the general global threat level. National characteristics as a driver also find some support. © 2014 Copyright © Taylor & Francis Group, LLC. Source

Fast, global, and sensitively reacting to political, economic and social events of any kind – these are attributes that social media like Twitter share with foreign exchange markets. Does the former allow us to predict the latter above chance level? The leading assumption of this paper is that time series of Tweet counts have predictive content for exchange rate movements. This assumption prompted a Twitter-based exchange rate model that harnesses regARIMA analyses for short-term out-of-sample ex post forecasts of the daily closing prices of EUR/USD spot exchange rates. The analyses made use of Tweet counts collected from January 1, 2012 – September 27, 2013 via the Otter API of topsy.com. To identify concepts mentioned on Twitter with a predictive potential the analysis followed a 2-step selection. Firstly, a heuristic qualitative analysis assembled a long list of 594 concepts, e.g., Merkel, Greece, Cyprus, crisis, chaos, growth, unemployment expected to covary with the ups and downs of the EUR/USD exchange rate. Secondly, cross-validation using window averaging with a fixed-sized rolling origin was deployed. This was instrumental in selecting concepts and corresponding univariate time series with error scores below chance level as defined by the random walk model that is based only on the EUR/USD exchange rate. With regard to a short list of 17 concepts (covariates), in particular SP(Standard & Poor’s) and risk, the out-of-sample predictive accuracy of the Twitter-based regARIMA model was found to be repeatedly better than that obtained from both the random walk model and a random noise covariate in 1-step ahead forecasts of the EUR/USD exchange rate. The increase in predictive strength facilitated by information gleaned from Twitter was evident on the level of forecast error metrics (MSFE, MAE) when a majority vote over different estimation windows was conducted. The results challenge the semi-strong form of the efficient market hypothesis (Fama Journal of Finance, 25, 383-417, 1970, Fama Journal of Finance, 46(15), 1575-1617, 1991) which when applied to the FX market maintains that all publicly available information is already integrated into exchange rates. © 2014, Springer Science+Business Media New York.

According to the basic needs of eating and drinking, new demands develop steadily for the assortment, the food production and trade. Beside the current trends in the food sector like "convenience", "health, fitness & wellness", "premium & pleasure", the subjects sustainability/ecological/green" gain in importance for the consumer. To counteract the narrow view on single sustainable (green) food product attributes and their influence on consumer behaviour, the following paper aims to provide an approach that includes several variables that have been considered to be of importance after reviewing existing literature to better understand the consumer and key drivers for their purchase intention towards green food products.

Sustainability reporting has attracted significant attention from the business as well as the academic community in recent years. Not only has the latter frequently made recommendations on reporting, it has also extensively examined factors that have an influence on reporting. Several studies have noted differences in the extent and style of reporting across countries, but the influence of specific cultural and socio-economic environments on reporting has only been given limited consideration so far. It is the goal of this paper to help fill this gap. For this purpose, we examine the sustainability reporting of the 100 largest companies in the United Kingdom and Finland, as both are highly developed countries in North-Western Europe, but with significantly different cultural and socio-economic systems. Aside from the extent of reporting and media used, we examine the reporting standards and guidelines applied. Moreover, the focus of disclosure (economic, social or environmental) was investigated, which also brings a new perspective to the academic literature. Our results suggest that the cultural and socio-economic environment has an impact on the extent of reporting, but with regard to the focus of reporting and the application of standards the results are mixed. A stronger shareholder oriented culture does not lead to a more extensive inclusion of economic issues in sustainability reporting, while the extent of environmental reporting depends on the strength of environmentalism. The impact of cultural and socio-economic factors on the application of standards, such as the Global Reporting Initiative, appears to be limited. © 2012 John Wiley & Sons, Ltd and ERP Environment.
