Plotting the Words of Econophysics. [PDF]
Entropy (Basel), 2021 Text mining is applied to 510 articles on econophysics to reconstruct the lexical evolution of the discipline from 1999 to 2020. The analysis of the relative frequency of the words used in the articles and their “visualization” allow us to draw some conclusions about the evolution of the discipline.

Time‐Frequency Analysis of COVID‐19 Shocks and Energy Commodities
Complexity, Volume 2023, Issue 1, 2023., 2023 In a time‐frequency biwavelet framework, we analysed the short‐, medium‐, and long‐term impacts of COVID‐19‐related shocks on ten energy commodities (i.e., Brent, crude oil, coal, heating oil, natural gas, gasoline, ethanol, naphtha, propane, and uranium) from January 2020 to April 2022.

Bounded rationality and animal spirits: a fluctuation-response approach to Slutsky matrices
Journal of Physics: Complexity, 2023 The Slutsky equation, central in consumer choice theory, is derived from the usual hypotheses underlying most standard models in Economics, such as full rationality, homogeneity, and absence of interactions.

Mathematical Methods in the Applied Sciences, Volume 45, Issue 8, Page 4597-4624, 30 May 2022., 2022 We consider two systems of nonlinear first‐order ordinary differential equations proposed to describe Ca2+‐levels in renal vascular smooth muscle cells and in liver cells. Initially, we present the models and its assumptions. We next investigate an approach to local solvability by Picard–Lindelöf 's Theorem.

The mutual predictability of Bitcoin and web search dynamics
Journal of Forecasting, Volume 41, Issue 3, Page 435-454, April 2022., 2022 Abstract Economic theory predicts the price dynamics of an unbacked asset to be inherently unforecastable. The same applies to exchange rates of unbacked currencies. Albeit, empirically investors are found to be driven by online and offline news media.

Discrete Dynamics in Nature and Society, Volume 2022, Issue 1, 2022., 2022 The intrinsic information shared by financial assets provides a means of assessing their mutual linkages. In times of crisis, spillovers and information flow between markets increase, and this drives empirical investigations into the degree of connectedness between financial assets.

Complexity, Volume 2022, Issue 1, 2022., 2022 Agent‐based models are computational approaches used to reproduce the interactions between economic agents. These models are widely applied in many contexts to get deeper understanding about agents’ behaviors within complex systems. In this paper, we provide a bibliometric analysis about agent‐based models in finance and, considering bibliographic ...

Complexity, Volume 2022, Issue 1, 2022., 2022 Liquidity risk arises from the inability to unwind or hedge trading positions at the prevailing market prices. The risk of liquidity is a wide and complex topic as it depends on several factors and causes. While much has been written on the subject, there exists no clear‐cut mathematical description of the phenomena and typical market risk modeling ...
