Reclaiming Relevance Through Problem‐Driven Interdisciplinary Research

Journal of Management Studies, EarlyView.
Abstract Management studies initially emerged as an applied field, uniquely positioned to tackle practical organizational problems through interdisciplinary research. Over time, however, the field has prioritized abstract theoretical contributions over real‐world engagement, fragmenting into disciplinary silos ill‐equipped to address complex ...

Econophysics and Financial Market Complexity [PDF]

, 2008
In this chapter we consider economic systems, and in particular financial systems, from the perspective of the physics of complex systems (i.e. statistical physics, the theory of critical phenomena, and their cognates). This field of research is known as

Structure and Evolution of the International Pesticide Trade Networks

Frontiers in Physics, 2021
To meet the increasing demand for food around the world, pesticides are widely used and will continue to be widely used in agricultural production to reduce yield losses and maintain product quality. International pesticide trade serves to reallocate the

Optimal Portfolio Choice With Cross‐Impact Propagators

Mathematical Finance, EarlyView.
ABSTRACT We consider a class of optimal portfolio choice problems in continuous time where the agent's transactions create both transient cross‐impact driven by a matrix‐valued Volterra propagator, as well as temporary price impact. We formulate this problem as the maximization of a revenue‐risk functional, where the agent also exploits available ...

Permutation Entropy and Its Main Biomedical and Econophysics Applications: A Review

Entropy, 2012
Entropy is a powerful tool for the analysis of time series, as it allows describing the probability distributions of the possible state of a system, and therefore the information encoded in it.

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.

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. It may be necessary to concentrate less on the applications than on the basics of economic complexity, beginning with expansion ...

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 ...
