Abstract

This paper explores the economic trends and identifies speculative bubbles within the emerging metaverse, based on the specific example of Decentraland, which is represented by its underlying native token MANA.For comparability, we consider three further tokens: SAND, ETH, and BTC.The study shows price prediction and provides further insight into bubble behavior to provide a deeper insight into the real trend and situation of the metaverse. When comparing all considered tokens, evidence of comovement and positive as well as negative bubbles is identified. This paper makes use of proven modeling techniques, such as SARIMA, for price prediction and LPPLS for financial bubble identification, visualization, and time stamping. [ABSTRACT FROM AUTHOR]

11. A matter of time and contacts: trans-local networks and long-term mobility of Eritrean refugees

Abstract

Eritreans have experienced protracted conflict and displacement over the last half a century. Aside from marginalisation, immobilisation, highly constrained livelihood options and legal limbo, this has also created a complex and dynamic web of transnational networks of Eritrean refugees and diasporas around the world. In this paper, we argue that protractedly displaced people are not only entangled with forced immobility but also encounter opportunities to create new migration pathways. This ethnographic study shows how protractedly displaced people build up socio-spatial connections and sequential small-scale mobility, circumventing the multiple constraints the governance regimes have placed upon them.

13. "ICI, PERSONNE N'EST D'ICI" (NOBODY HERE IS FROM HERE). DIASPORA IN SENEGAL

Author

Rudolf, Markus

Abstract

Abstract:The concept of diaspora can offer a new perspective on processes of integration and exclusion inside a nation. The concept helps to analyze internal displacement and national migration. Observations on the Diola in Senegal show how mechanisms of identification are contextually determined. Interviews in Dakar reveal that the status of internal immigrants from the Casamance can be understood better if they are regarded as a diaspora. At the same time the Diola diaspora located in trans-border regions features more integrative characteristics than are found in Dakar. The comparative analysis of diaspora facilitates an understanding of the relative importance actors attribute to different identifications. This approach helps to answer the question whether, where, and why local or national components of individual identifications are prioritized. The case study of instances where nation-building fails to integrate its subjects also points to difficulties of the current "nation state" model in general. Le concept de diaspora nous offre une nouvelle perspective d'analyse quant au processus d'intégration ou d'exclusion à l'intérieur même d'un pays. Ce concept nous aide à appréhender les migrations nationales et les déplacements à l'intérieur d'un pays. L'étude des Diolas au Sénégal nous montre la façon dont les mécanismes d'identification sont déterminés par le contexte. Des entretiens à Dakar montrent que le statut des immigrants de Casamance peut être compris de façon plus complète si l'on considère leur migration comme une diaspora. En même temps, les Diolas en diaspora installés dans des régions frontalières présentent des caractéristiques d'intégration plus grandes qu'à Dakar. L'analyse comparative des diasporas facilite la compréhension de l'importance relative que les divers acteurs accordant aux différents modes d'identification. Cette approche aide à répondre à la question de savoir pourquoi, ou et comment les éléments locaux et internationaux des modes d'indentification individuels sont choisis et hiérarchisés. Cette étude développe aussi des exemples dans lesquels le processus de construction de la nation échoue à intégrer des individus et met ainsi en évidence, de manière générale, les difficultés du modèle de l'Etat-Nation.

14. Sentimental Sustainability: Does What Companies Say Tell More Than What Companies Do?

Abstract

Based on a sample of more than eleven thousand unique 10‐K reports of US companies filed with SEC in period 2013 to 2018, this study examines the relationship between actual sustainability performance of companies, evaluated by MSCI ESG performance scores, and the extent and the scope of environmental, social, and governance information disclosure in their annual reports. The study shows empirical evidence supporting the signalling theory view of voluntary disclosure of ESG information in annual reports for most industries, while environmentally unfriendly companies belonging to the Mining industry division show excessive reporting behavior favoring environmental topics, which is consistent with incentives to improve public image and mitigate social, political, and legal risks in line with the legitimacy theory of information disclosure. When differentiating between forward‐looking and non‐forward‐looking ESG statements, the study shows that companies providing more forward‐looking ESG information in annual reports show better next‐year ESG performance. This study implements established content analysis techniques with focus on ESG reporting and performance, building up on the study of Baier, Berninger, and Kiesel (2020) that proposed an ESG‐tailored dictionary for textual analysis purposes.
