Modeling Financial Market Using Percolation Theory
P. 47–53.
Byachkova A.
Econophysics is a relatively new discipline. It is one of the most interesting and promising trends in modeling complex economic systems such as financial markets. In this paper we use the approach of econophysics to explain various mechanisms of price formation in the stock market. We study a model, which was proposed by Jean-Philippe Bouchaud and Dietrich Stauffer (Bouchaud 2002; Chang et al. 2002; Stauffer 2001; Stauffer and Sornette 1990), and used to describe the agents’ cooperation in the market. The most important point of this research is the calibration of the model, using real market conditions to proof the model’s possibility of setting out a real market pricing process

This study employs novel decomposed connectedness and portfolio analysis to assess the dynamic spillover effects among carbon finance, artificial intelligence, green energy markets, and bitcoin. The findings indicate that the average total connectedness index is 62%, especially during extreme market conditions. The decomposition of this measure into contemporaneous and lagged connectedness reveals that 56% of ...

We develop a neural network approach to solve the self-consistent Bogoliubov-de Gennes equations in strongly disordered s-wave superconductors. The method accurately reproduces inhomogeneous gap distributions and generalizes to system sizes far larger than those used in training. It reduces computational scaling from O(N6 ) to O(N2), enabling quantitative analysis of percolation phenomena and the superconductor-insulator ...

Banks are the central link in the national financial market and the economy as a whole. The share of bank assets in the asset structure of the Russian financial market, despite a slight decline, remains dominant relative to other participants, reaching 80%.
Russian banks are multifaceted. On the one hand, they provide working capital financing, long-term ...

The basis of the international financial market is foreign exchange flows arising from the functioning of the world economy. The main task of financial flows is to exchange the results of the activities of world economies. Therefore, the essence of the international financial market is to support the movement of foreign currency flows between financial ...

The sanctions pressure of the United States and the European Union on our country aims to weaken the Russian economy. In other words, to exclude banks’ operations on the international financial market and, if possible, freeze their assets. In February 2022, sanctions were imposed against Russian credit institutions, such as: disconnection from SWIFT, a ban ...

We analyze correlation structures in financial markets by coarse graining the Pearson correlation matrices according to market sectors to obtain Guhr matrices using Guhr’s correlation method according to P Rinn et al (2015, Europhysics Letters 110, 68 003). We compare the results for the evolution of market states and the corresponding transition matrices with those ...

Analyzing market states of the S&P 500 components on a time horizon January 3, 2006 to August 10, 2023, we found the appearance of a new market state not previously seen, which implies an isolated state or the beginning of a new general market condition. We study this in terms of the Pearson correlation matrix and relative ...

The current conditions of economic and political instability raise serious questions about the sustainability of the global fi nancial and economic system. The study of fi nancial markets of developed countries indicates their "overheating" and emphasises the necessity to search for alternative directions for global capital investments. The paper analyses the potential of BRICS development ...

Recent advances in the field of machine learning have yielded novel research perspectives in behavioural economics and financial markets microstructure studies. In this paper we study the impact of individual trader leaning characteristics on markets using a stock market simulator designed with a multi-agent architecture. Each agent, representing an autonomous investor, trades stocks through reinforcement ...

The global financial system is constantly changing, rapidly reacting on the external changes. These changes include evolving macroeconomic policy tools, creation of new regulations in financial markets (affecting both banking institutions, financial markets’ benchmarks, etc.), imposition of legal restrictions of dealing with certain types of financial institutors on the basis of decisions of particular governments, ...

We ask whether empirical finance market data (Financial Stress Index, swap and equity, emerging
and developed, corporate and government, short and long maturity), with their recently observed
alternations between calm periods and financial turmoil, could be described by a low‑dimensional
deterministic model, or whether this requests a stochastic approach. We find that a deterministic
model performs at least as ...
