We examine whether exogenous and extremely negative events, such as terrorist attacks and mass shootings, influence the sentiment and forecasts of sell-side equity analysts. We find that analysts who are local to these attacks issue forecasts that are relatively more pessimistic than the consensus forecast. This effect is stronger when the analyst is closer to the event and located in a low-crime region. Impacted analysts are also relatively more pessimistic around the one- and two-year anniversaries of the attacks. Collectively, these findings indicate that exposure to extreme negative events affects the behavior of information intermediaries and the information dissemination process in financial markets. This paper was accepted by David Simchi-Levi, finance.

This is the Information Age, and that epicenter is information flow and content control. This is the one occupation that is best suited to benefit from this still evolving epoch of human history. In fact, any organization that fundamentally relies on information dissemination as a core resource to their production would seek out information experts as the de facto experts in this field for consultation on how best to handle their large volumes of information. Today, companies are searching for these very professionals and will pay extraordinarily well to have such expertise in their organizations. As long as they change their mindset, evolve from conservative ideologies of what a library professional is, and retain and improve upon the traditional library services while seeking to develop techniques and technologies that effectively handle the workflow of the information dissemination process in a Digital Age—adapting technologies such as the KATIE Index, the MEL System, and the LISA Informationbase for the physical and virtual collection management requirements—most library professionals will be able to focus on becoming information experts and establish their relevance at the very epicenter of business and education. Evolving into the information expert and leveraging new information technologies is where the future of library studies lays in this digital segment of the Information Age. This chapter concludes the first section of the book.

In attempting to understand the bewildering complexity of consumer markets, financial markets, and beyond, traditional textbooks and theories will not help much. This book presents a new market theory in which information plays the most important role. Markets are portrayed with three categories of actor: consumers, businesses, and information intermediaries. The reader can determine his own role, and with analysis and examples from the real-world economy, new questions can be raised and individual conclusions drawn. The aim is to stimulate the reader’s own thinking, either as a consumer on the high street, an investor on Wall Street, a policy maker in a government armchair, or an entrepreneur dreaming of the next big opportunity. This book should also generate and inspire academic debates, as the claims and conclusions are often at odds with mainstream theory.

Abstract A recently published paper in this journal (Choi, 2021) establishes a statistical link between, on the one hand, Islamist terrorist campaigns – including terrorist attacks and online propaganda – and, on the other the growth of the Muslim population. The author explains this result by stating that successful campaigns lead some individuals to convert to Islam. In this commentary, we intend to reply to this article by focusing on the impact of terrorist attacks on religious conversion. We first show that Choi's results suffer from theoretical flaws – a failure to comprehensively unpack the link between violence and conversion – and methodological shortcomings – a focus on all terrorist groups over a period where Islamist attacks were rare. This leads us to replicate Choi's analysis by distinguishing Islamist and non-Islamist terror attacks on a more adequate timeframe. By doing so, we no longer find empirical support for the relationship between terror attacks and the growth of the Muslim population. However, our analyses suggest that such a hypothesis may hold but only in contexts where the level and intensity of political violence are high.

Surveillance of a seaport can be achieved by different means: radar, sonar, cameras, radio communications and so on. Such a surveillance aims, on the one hand, to manage cargo and tanker traffic, and, on the other hand, to prevent terrorist attacks in sensitive areas. In this paper an application to video-surveillance of a seaport entrance is presented, and more particularly, the different steps enabling to classify mobile shapes. This classification is based on a parameter measuring the similarity degree between the shape under study and a set of reference shapes. The classification result describes the considered mobile in terms of shape and speed.

Compared with investing an ordinary options, investing the power options may possibly yield greater returns. On the one hand, the power option is the best choice for those who want to maximize the leverage of the underlying market movements. On the other hand, power options can also prevent the financial market changes caused by the sharp fluctuations of the underlying assets. In this paper, we investigate the power option pricing problem in which the price of the underlying asset follows the Ornstein–Uhlenbeck type of model involving an uncertain fractional differential equation. Based on critical value criterion, the pricing formulas of European power options are derived. Finally, some numerical experiments are performed to illustrate the results.

AbstractThis paper reviews the development of agent-based (computational) economics (ACE) from an econometrics viewpoint. The review comprises three stages, characterizing the past, the present, and the future of this development. The first two stages can be interpreted as an attempt to build the econometric foundation of ACE, and, through that, enrich its empirical content. The second stage may then invoke a reverse reflection on the possible agent-based foundation of econometrics. While ACE modeling has been applied to different branches of economics, the one, and probably the only one, which is able to provide evidence of this three-stage development is finance or financial economics. We will, therefore, focus our review only on the literature of agent-based computational finance, or, more specifically, the agent-based modeling of financial markets.

Traditional legal doctrine calls for hard law to regulate markets. Nevertheless, in financial markets, soft law has a long tradition, not at least due to the lack of multilateral agreements in this field. On the one hand, the recent financial crisis has shown that soft law does not suffice to avoid detrimental developments; on the other hand, a straight call for hard law would not be able to manage the recognized regulatory weaknesses. Therefore, emphasis should be put on the possibilities of combining hard law and soft law; specific areas allowing realizing such kind of “combination” are organizational issues, transparency requirements, and dispute settlement mechanisms.

Compared to other domains of media discourse, economic-financial news contain a considerable amount of speech acts regarding future events, in particular predictions. This can be explained by their specific institutional context, financial markets, where investors constantly seek to single out gain opportunities and to correctly assess their risk. One of the crucial factors making economic-financial predictions worthy of being considered in investment decisions is argumentation, in particular the extent to which the predicted proposition follows from a plausible and acceptable reasoning. Starting from a corpus of 50 articles of the Italian economic-financial press, we consider the inferential dimension of prediction-oriented arguments, focusing on the locus, i.e. the ontological relation on which the connection between the argument(s) and the predictive conclusion rests. All predictions found in the corpus were manually annotated with the software UAM Corpus Tool. For each of them we identified the source, which could be either the journalist him/herself or a third party, typically financial analysts or corporate actors. We distinguished mere predictive opinions from predictive standpoints, i.e. predictions for which the journalist advances one or more supportive arguments (either confirmatory of refutatory). For the latter category, we identified the locus referring to an adaptation of the taxonomy outlined by Rigotti (2009). The findings highlight in particular the following three interesting aspects: (1) in predictions, journalists reinforce their stance by plausible justifications, but weaken it at the same time by marking it as uncertain and/or by using reported speech or evidential means to reduce their responsibility for the predictive speech act; (2) the justification of a predictive standpoint, by the journalist or by third parties, is mostly based on loci of causality, in particular on the locus from efficient cause, the locus from final cause and complex forms of causality where the involvement of rational agents is implied but defocused; (3) moreover, journalists refer to the predictive opinions of experts or corporate insiders to activate the locus from authority, either by explicit argumentation or implicitly, by reporting speech from reliable sources. Our study suggests that the role of predictions in financial news is not so much that of giving any straightforward advice to investors, but rather that of providing chunks of sound argumentative reasoning, including both supportive evidence and rebuttals or refutatory moves, that the investor-reader might apply and combine in the highly uncertain context of financial markets. Overall, our findings shed light on how financial journalists fulfil the function of information intermediaries in finance.
