News sentiment and sovereign credit risk

We explore the impact of media content on sovereign credit risk. Our measure of media tone is extracted from the Thomson Reuters News Analytics database. As a proxy for sovereign credit risk we consider credit default swap (CDS) spreads, which are decomposed into their risk premium and default risk components. We find that media tone explains and predicts CDS returns and is a mixture of noise and information. Its effect on risk premium induces a temporary change in investors’ appetite for credit risk exposure, whereas its impact on the default component leads to reassessments of the fundamentals of sovereign economies.     

Social media bots and stock markets

This study examines the link between information spread by social media bots and stock trading. Based on a large sample of tweets mentioning 55 companies in the FTSE 100 composites, we find significant relations between bot tweets and stock returns, volatility, and trading volume at both daily and intraday levels. These results are also confirmed by an event study of stock response following abnormal increases in the volume of tweets. The findings are robust to various specifications, including controlling for traditional news channel, alternative measures of volatility, information flows in pretrading hours, and different measures of sentiment.     

Personality traits,basic individual values and GMO risk perception of twitter users

Abstract

The present study investigates how the most foundational factors to individual differences – personality traits and personal values – affect the perceived safety of genetic modification and their relative importance. Publicly available communication data from 522 Twitter accounts discussing genetically modified foods and their safety was processed in two steps. First, accounts were categorized by the researchers as viewing GM foods as either safe or not safe. Second, using the IBM Watson platform, the Twitter communication data were subjected to lexical analysis to assign scores according to the Five Factor Model for personality traits and Schwartz’s basic individual values to the individual accounts. Logistic regression analyses were performed to determine how perceived GM food safety is linked to personality traits and individual values. Although both traits and values significantly contribute to explaining GM attitudes, personality traits strongly moderate the effect of individual values on risk perception.     

FDI与我国高技术产业技术创新关系研究——基于2005-2014年省际面板数据

改革开放以来，中国大量吸引外商直接投资，期望以此提升国内的技术创新能力。然而，在当前的背景下，我国期望通过FDI提高技术创新能力的目标是否已经实现？我国各地区高新技术产业究竟需不需要外资？等问题值得我们深入研究。实证结果表明：FDI对我国东部地区高技术产业的影响为正，对其他地区影响为负。因此，应当根据我国各地区高技术产业发展水平，实施差异化引资策略，加强知识积累、人力资本建设，为高技术产业的发展提供基础。     

A netnographic sensibility: developing the netnographic/social listening boundaries

Netnography is constantly evolving as technologies and access to online data develop. Our paper outlines how large data sets of social media can be analysed through bridging the divide between the small, rich and contextually nuanced data that is the hallmark of netnography and the scope and scale of data made possible through social media listening conventions. We define this approach as netnographic sensibility and with the use of a short case study discuss the process through which social media data could be gathered, triangulated and analysed. We orientate the paper around two interrelated questions: investigating how netnographic insights can be extended using social media monitoring tools, and asking how this can be used to add richness and depth to understanding mass consumer realities. Our contribution complements the widely established methodological approach of netnography as we argue that netnography has the capacity and capability to embrace technological advances within the domain of social listening to add value for academic researchers.     

The Improbability of Fraud in Accounting for Derivatives: A Case Study on the Boundaries of Financial Reporting Compliance

ABSTRACT

This study responds to recent calls in the literature to examine fraud using detailed case studies, extending knowledge beyond individual incentives and capital market reactions towards a more contextualized understanding of the concept. We use an institutional logics perspective to challenge existing assumptions about a universally valid meaning of compliance, fraud, and faithful representation. Presenting the case of the Swedish bank HQ, we show how the interpretation of the accounting standard for option measurement varies across different enforcement bodies because the meaning of compliance is socially negotiated across the institutional logics of markets, financial regulation, and law. The independent decision-making of the different enforcement bodies leads to a systematic variation in the interpretation of principles-based accounting standards without ultimate coordination. To define consistent boundaries of compliance across institutional logics, and thus, to distinguish between fraud and allowable managerial discretion becomes problematic. Faithful representation, in turn, cannot be understood as financial statements reflecting a correct value or as financial statements being prepared in accordance with acceptable practice, as suggested in the earlier literature. Instead, faithful representation itself becomes a contextually bound concept, which can only be defined within an institutional logic.
