The paper elaborates some analytical opportunities for econophysics in the implementation of Basel II documents for banking. We see this chances by reviewing some methodologies proposed by the econophysicists in the three important aspects of risk management: the market risk, credit risk, and...

Time series of obligations with the public are important to liquidity risk management in emerging economies, but a traditional parametric VaR model could give imprecise measures of liquidity risk if the series do not approach a normal (Gaussian) distribution. To overcome this flaw of parametric...

Asymptotic Single Risk Factor (ASRF) model is used to derive the regulatory capital formula of Internal Ratings-Based approach in the new Basel accord (Basel II). One of the important assumptions in ASRF model for credit risk is that the given portfolio is well diversified so that one can easily...

This paper analyzes the measurement of credit risk capital requirements under the new Basel Accord (Basel II): the Internal Rating Based approach (IRB). It focuses in the analytical formula for its calculation, since its derivation to the main assumptions behind it. We also estimate the credit...

In the paper, I simulate the games with a joint presence of 95% VaR-rule and return-rule groups of agents in the game. Simulations highlighted the level of omniscience, next being the rule, which agents follow at the decision-making, and the third the presence of liquidity agents in the game....

The capital structure of firms that face restrictions on liquidity (i.e. that cannot hedge continuously) is affected by the agency costs and moral-hazard implicit in the contracts they establish with stockholders and customers. It is demonstrated in this paper that then an optimal level of...

In the paper, I simulate the social network games of a portfolio selection where agents consider VaR when managing their portfolios. Such agents behave quite differently from the agents considering only the expected returns of the alternatives that are available to them in time. The level of...

Since the capital structure affects the performance of financial institutions confronted to liquidity constraints, the Economic Capital is determined by the maximisation of value. Allowing economic decisions to be characterised by a distorted probability distribution, so assessing the attitude...

Basel II suggests that banks estimate downturn loss given default (DLGD) in capital requirement calculation. There have been studies that focused on the dependence of default rates and loss given defaults through economic cycles. However, the models proposed are still not satisfactory. In this...

The paper studies the impact of different time-scales on the market risk of individual stock market returns and of a given portfolio in Paris Stock Market by applying the wavelet analysis. To investigate the scaling properties of stock market returns and the lead/lag relationship between them at...
