Special Issue Information

Dear Colleagues,

After the first Special Issue dedicated to this theme, we are now opening a second volume that considers the same basis and the recognition that financial markets could be described as complex systems not only due to their own behaviour but also because of the way that agents interact and their dynamics. Moreover, in the actual context of the COVID-19 pandemic, this complexity surely increases, implying the need for continuous monitoring of financial markets when some of the fluctuations of the markets remain unexplained. The appearance of Econophysics as an autonomous research field dates back to the 1990s, when many researchers started to apply statistical physics methods to financial data. The term Econophysics was originally applied by H. Eugene Stanley, with the objective of calling attention to the high number or papers that were already published even at that time. Since then, the number of publications has increased significantly, and Econophysics is now recognized as an independent research area. Within the context where so much about financial markets is unexplained, where technological advances make financial markets more available (inclusively creating new financial services), where financial markets are, in general, more interconnected, it remains important to keep the focus on studying those markets. Hence, in this Special Issue, we will attempt to understand the behaviour of financial markets based on the use of methods of Econophysics.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Financial Studies is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs).

The change of information near light speed, advances in high-speed trading, spatial arbitrage strategies and foreseen space exploration, suggest the need to consider the effects of the theory of relativity in finance models. Time and space, under certain circumstances, are not dissociated and can no longer be interpreted as Euclidean. This paper provides an overview of the research made in this field while formally defining the key notions of spacetime, proper time and an understanding of how time dilation impacts financial models. We illustrate how special relativity modifies option pricing and hedging, under the Black–Scholes model, when market participants are in two different reference frames. In particular, we look into maturity and volatility relativistic effects. Full article

The notion of “relativistic finance” became ingrained in the public imagination and has been asserted in many mass-media reports. However, despite an observed drive of the most reputable Wall Street firms to establish their servers ever closer to the trading hubs, there is surprisingly little concrete information related to the relativistic delay of the trading orders. There is an underlying assumption that faster electronics are always beneficial to the stability of the network. In this paper, the author proposes a modified M/M/G queue theory to describe the propagation of the trading signal with finite velocity. Based on this theory, we demonstrate that, even if the reaction time of the system is negligible, the propagating signal is distorted by simple acts of trading along the transmission line.
