We propose phase-like characteristics in scale-free broadband processes and consider fluctuation synchrony based on the temporal signature of significant amplitude fluctuation. Using wavelet transform, successful captures of similar fluctuation pattern between such broadband processes are demonstrated. The application to the financial data leading to the 2008 financial crisis reveals the transi...

Financial institutions are performing large scale migrations of their systems from DES to triple-DES. In this white paper we describe the basic characteristics of DES and triple-DES and look at the security properties that a financial transaction system will want to achieve. We then look at the problems related with a migration from DES to triple-DES, enumerating and discussing several points t...

We develop threshold models that allow copula functions or their association parameters changing across time. The number and location of thresholds is assumed unknown. We use a Markov chain Monte Carlo strategy combined with Laplace estimates that evaluate the required marginal densities for a given model. We apply our methodology to financial time series emphasizing the ability to improve esti...

the performance valuation of the economic enterprise inorder to confidence of limited resources’ optimum allocation is important affaire and as long as it isn’t use of appropriate indicator for performance measurement and stock value of the firm its value not toward reale value and capital doesn’t allocate truly. this subject is more sensitivity in inflation condition. the goal of this research...

Financial risk is an objective phenomenon in economic activities. It has received extensive attention in theoretical and practical fields. For each company and operators in the market economy, the financial risk is an objective existence. The manufacturing industry as a pillar industry of China’s economic development, occupies a large proportion in China’s listed company. However because of the...

Bank failure prediction is an important issue for the regulators of the banking industries. The collapse and failure of a bank could trigger an adverse financial repercussion and generate negative impacts such as a massive bail out cost for the failing bank and loss of confidence from the investors and depositors. Very often, bank failures are due to financial distress. Hence, it is desirable t...

In this paper we construct a modeling for detection of banks which are experiencing serious problems. Sample and variable set of the study contains 30 banks of Iran during 2006-2014 and their financial ratios. Well known multivariate statistical technique (principal component analysis) was used to explore the basic financial characteristics of the banks, and discriminant Logit and Probit models ...
