International Studies of Economics, Volume 21, Issue 3, Page 230-248, September 2026.ABSTRACT In this article, we apply the notion of gravitational fields to commercial attraction, with the aim of providing valuable insights to inform the development of an econophysical methodology. We revisit the traditional notion of gravitational fields, extending it to encompass multiple economic variables and incorporating mobility and production ...

Econophysics deserves a revamping
CoRR, 2019 The paper argues that attracting more economists and adopting a more-precise definition of dynamic complexity might help econophysics acquire more attention in the economics community and bring new lymph to economic research.

A Learning Model with Memory in the Financial Markets
International Journal of Finance &Economics, Volume 31, Issue 1, Page 1203-1213, January 2026.ABSTRACT Learning is central to a financial agent's aspiration to gain persistent strategic advantage in asset value maximisation. The implicit mechanism that transforms this aspiration into an observed value gain is the speed of error corrections (demonstrating, an agent's speed of learning) whilst facing increased uncertainty.

The impact of cryptocurrency heists on Bitcoin's market efficiency
International Journal of Finance &Economics, Volume 30, Issue 3, Page 2912-2929, July 2025.Abstract Within the adaptive market hypothesis (AMH) framework, this study explores the dynamic impact of cryptocurrency heists on Bitcoin's market efficiency. By analysing Bitcoin's one‐minute price data, we calculate permutation entropy to assess market disorder and employ the complexity‐entropy causality plane to quantify structural changes in the ...
